Everyone's looking for energy fixes in all the wrong places.
(Page 2 of 2)
The only way to make up for the relatively low density of solar
flow is to use more land in gathering it. There is no
Moore's Law waiting to improve the process. Solar cells, windmills,
and other forms of solar flow may be made cheaper—which is
where most of the research is going right now—but landrequirements will never be reduced. Those
requirements, when confronted, turn out to be staggering. In a 2007
essay that is becoming a classic, Jesse Ausubel, of the Program for
the Human Environment at Rockefeller University, calculated the
amount of land that would be required to equal the output from
fossil fuels using so-called "renewable" energy. Running a
1,000-megawatt electrical station—the standard size—for example,
would require 1,000 square miles of forest. A hydroelectric dam
generating 1,000 MW usually backs up a reservoir of about 250
square miles. T. Boone Pickens's plan to generate 4,000 MW of
electricity from wind in west Texas will cover around 1,200 square
miles. In the December 2007 issue of Scientific American,
three solar energy theorists presented a "grand plan for solar
energy" that would involve powering the entire country by covering
30,000 square miles of Southwest desert with solar collectors.
No amount of technical ingenuity or venture capital flowing out
of Silicon Valley is ever going to change these parameters. Cool
Earth Solar, for example, a company in Livermore, California, has
invented an eight-foot balloon whose surface acts as a magnifying
glass to concentrate solar energy on a small photovoltaic cell at
its center. This will cut down on the requirements for expensive
solar cells. But it will not reduce the space required by the
balloons. Bob Metcalfe, co-founder of the Ethernet, is heading
GreenFuel Technologies, a Massachusetts company developing
photosynthetic algae that will convert the carbon exhausts from a
coal plant into biofuel. But the algae pools for a single 1,000-MW
coal plant will cover 40 square miles.
Both fossil fuels and solar flows have their limitations. Fossil
fuels can produce only so much energy from their chemical bonds.
Solar flows can be increased only by covering more land. So is
there any other source of energy that can surpass these
limitations?
IT TURNS OUT THERE IS. We just haven't gone down far enough into
the microcosm. If we go down one step further, we encounter the
greatest storehouse of energy in the universe: the nucleus of the
atom.
To understand the dimensions of the energy stored in the atomic
nucleus, it is best to begin with Einstein's formula E = mc2.
Almost everyone has heard of it (it is the title of one of Mariah
Carey's recent albums), yet how many people understand exactly what
it means?
Einstein's formula says that matter and energy are
interchangeable. They form a continuum. Energy can be converted to
matter and matter can be converted to energy. The important thing
is the coefficient— the speed of light squared. That is a
very, very large number, on the order of one quadrillion. What it
says is that a very, very small amount of matter
translates into a very, very large amount of energy.
These transformations take place at the atomic level, both
within the electron shells and in the nucleus. It is the
distribution of matter between the two that defines the difference.
More than 99.9 percent of the mass of an atom is within its
nucleus. That translates into vast stores of energy, beyond
anything we encounter in the "chemical" reactions of the electron
shell. If producing energy comes from the conversion of matter,
there is only one logical place to look for large amounts of
matter: in the nucleus of the atom. Over the course of the early
20th century, a generation of brilliant European scientists—Marie
Curie, Niels Bohr, Werner Heisenberg, Enrico Fermi, Leo
Szilard—gradually unlocked the secret of the vast quantities of
potential energy in the nucleus of the atom. Then as World War II
approached, many of these scientists migrated to America to help
build the atomic bomb. Ever since, the idea of "nuclear power" has
been fatefully intertwined with nuclear weapons.
A far better way to think of nuclear power, however, is as
"terrestrial energy," because that is where we encounter it. As
Einstein said to his fellow scientists when he signed the letter to
President Roosevelt, "For the first time in history, mankind will
be using energy not derived from the sun."
Terrestrial energy—"nuclear energy"—is derived from the
breakdown of the uranium and thorium atoms, two of the three
heaviest atoms. They are so large that they are unstable and
therefore "radioactive." Radioactivity is a release of energy. When
uranium and thorium break down in the earth's crust, they release
enough energy to raise the earth's core temperature to 7,000
degrees Fahrenheit—hotterthan the surface of the
sun. Although no one has ever calculated the exact portion,
anywhere from 50 to 90 percent of the earth's internal heat is
believed to come from these two elements.
When we mine uranium or thorium and accelerate their breakdown
in a controlled environment, we have what is called a "nuclear
reactor." In doing this, we are simply borrowing terrestrial energy
from nature—just as we borrow solar energy in the form of
photovoltaics, hydroelectric dams, and fossil fuels.
The only difference is the energy density. You will
recall that the breaking of a carbon-hydrogen bond in coal or oil
produces 1 electron volt. The disintegration of the nucleus of a
single uranium atom produces 200 million electron volts.
This extraordinary concentration of matter means that vast amounts
of energy can be generated from very small quantities of this
natural resource.
For example, a 1,000-MW coal plant is fed by a 110-car "unit
train" of coal cars arriving at the plant every 18 hours. (Such a
unit train now leaves the Powder River Basin of Wyoming to
distribute coal around the nation every six minutes. In 1999 it was
every 25 minutes.) A 1,000-MW nuclear reactor, on the other hand,
is supplied by a single tractor-trailer that arrives at the reactor
with a new supply of fuel rods every 18 months.
This extraordinary concentration of energy occurs on the back
end as well. The same 1,000-MW coal plant will release three
million tons of carbon dioxide exhausts into the atmosphere every
year, while the reactor's emissions are zero. The only "waste" is
the highly radioactive fuel rods that— properly reprocessed—can
produce even more energy. France, which has a complete nuclear
cycle, gets 30 percent of its reactor fuel from spent fuel rods.
All the remaining "waste" from 30 years of producing 75 percent of
its electricity from nuclear power is stored beneath the floor in a
single room at the La Hague plant in Normandy.
So there is plenty of energy at the bottom. We just haven't
realized where it is yet. The place to look for both for an
abundant supply of energy and the answer to our environmental
problems from generating energy is in the nucleus of the atom.
William Tucker is a shill for the nuclear industry. While he
sings a pretty song about nuclear power he neglects to mention
the lingering curse of radioactive pollution produced by the
nuclear industry.
In response to his article, I say:
* No nuclear power.
And ...
* No coal power.
If humankind cannot survive without electricity our species will
go extinct. Since humankind cannot survive without electricity,
our species will certainly go extinct.
Addiction to electricity and technology has driven humankind on a
dead-end path. Our civilization is dying and no amount of
desperation will save it from collapse.
Let it go.

My company offers solar solutions to homeowners as part of a

homeowner buy a solar system because the cost benefit ration just
isn't there.
If every existing home in America was refitted with the best
insulation practices and we had nuclear power for our energy
needs, americas need for power, not including vehicles, would
drop in half

David Mathews’ solution is that we rely on bicycles made of hemp
for our transportation needs, but doing so would require a
significant downsizing in the world’s population. While I’m sure
that he is willing and able to assist in the necessary reductions
with great enthusiasm, I think that it’s kindler and gentler to
build nukes at breakneck pace to sate the population’s growing
stationary energy needs. Moreover, over a short time excess nuke
capacity could generate hydrogen, a medium suitable for fueling
our mobile transportation needs.
So the contrast is simply that Mr. Mathews wants to drive
humanity back to the caves and savannahs while more thoughtful
folks seek to deploy the harnessed atom in a manner that
engenders human prosperity. And he’s the progressive?

Nuclear power isn't going to save civilization. Nuclear power is
desperation ... sort of like the intensive care unit for Terry
Schiavo.
Humankind will lose electricity and technology and if it is not
possible for humankind to survive without these the species will
go extinct. Technological civilization is a dead-end path.

mike b| 4.24.09 @ 9:08AM
the problem with nuclear "waste" was created when Jimmy Carter
decided that reprocessing nuclear fuel rods was not going to be
allowed. Commercial fuel rods are only about 3% enriched uranium,
while nukie sub reactor rods are considerably higher. France
supplies about 70% of their power with nuclear, and reprocess the
rods. It is, in simple terms, recovering the uranium from fuel
rods that that has not been consumed and putting that in new
rods. It is my understanding the total amount of French "waste"
has a foot print of about 2000 sq. ft. The US nuclear industry
has been paying the federal gov't for years to support the Yucca
Mountain facility, while Congress (think Harry Reid) has been
intentionally dragging their feet to get it finished. Start
reprocessing the fuel, and the amount of waste would be miniscule
in comparison to what it is today. As for Dave Mathews
comments---he is fortunate to live in a country that has the 1st
amendment that protects his right to express his opinion

Libtard morons. True believers they are.
We are to emulate the great europeans in everything but that
which has actually worked.
Germany is the model for wind and solar and guess what ? It is
not the panacea that the left has promised. France, on the other
hand, derives some 80% of it's electricity from Nuclear fuel. No
problem. DM, your claims were made by many others since the '60's
- dire predictions of impending doom and population crash. They
have all been wrong - wrong then and wrong now.
Trust me if solar could be made to work efficiently, it would not
require one government subsidy.
DaveS| 4.24.09 @ 10:01AM
Tucker got one thing kind of wrong, but he may have done so for
reasons of simplicity: when uranium and thorium decay, they
produce the energy he speaks of at the earth's core. When uranium
(-233 or -235) fissions you get about 160 MeV in fission fragment
kinetic energy with the rest is neutrons and gamma. The thorium
is useful when bred to U-233. Other than that, the facts (Mr.
Matthews) speak for themselves. God has created a pretty
marvelous energy source - born solar and discovered terrestrial.
Everything else pales or is pipe dream.
dcd| 4.24.09 @ 10:26AM
Government subsidies are the problem. Except for basic research
the government should get out of the game; no direct or indirect
subsidies for ethanol, solar, hydrocarbons, or nuclear. An
industry should cover its own expenses, pay full market price for
what it takes, and persuade the locals that it is an acceptable
neighbor without the federal government's pocketbook or muscle.

I am wondering here if this doesn't scare the EW's, Environmental
Wacko's, as much as attempting to actually use solar power? They
are screaming about trashing the Mojave desert to try major wind
and solar plants, they complain about endangering birds and
migration patterns at existing wind plants in California and
obviously the technology for safe nuclear is already here and has
been.
Using the technology from the next generation reactors and
producing a stable cost effective source of hydrogen power for
vehicles, and we laugh at the world still using something quaint
like oil for vehicles and coal for power.
With so many upsides, the only downside is the threat of EW's. It
just provides further proof rational debate is non existent when
it comes to the environment. It's not the environment any more,
it's control as has been pointed out in many other articles.
Let's hope reason will at some point prevail if enough of US keep
hammering away at politicians of both sides until they get the
message.

Fiat lux| 4.24.09 @ 1:44PM
We already use the most efficient and safe ‘terrestrial
energy’…
“A liter of gasoline, for example, can produce 9.7 kilowatt-
hours (kWh) of power—probably the densest form of chemical energy
we will ever encounter.”
…oil. Petroleum and its derivatives natural gas and coal
originate deep under the earth’s crust/upper mantle from iron
oxide (earth has an iron core), calcium carbonate (marble) with a
touch of water at high pressures and heat.
(http://www.gasresources.net/AlkaneGenesis.htm) The sun and plant
life has/had nothing to do with the creation of oil. The laws of
thermodynamics prohibit low energy material (cold water/bio-mass)
to magically become high energy material (hot water/petroleum).
Naval Architect| 4.24.09 @ 2:32PM
To JamesD:
The Navy has a program for decommissioning and recycling nuclear
powered naval vessels, see
http://en.wikipedia.org/wiki/Ship-Submarine_recycling_program
The nuclear fuel contained in these reactors is removed and
re-processed. The reactor compartments are then buried at
Hanford, WA.
Fiat lux| 4.24.09 @ 2:43PM
The progression of high carbon fuels to low carbon fuels has been
happening for the past 140 plus years. Hydrogen/Carbon ratios:
Wood – 1/10, coal – 1/2, oil – 2/1, natural gas – 4/1
The future of energy follows this progression to a carbonless
fuel. H20. Water. Hydrogen. Not the hydrogen cell. Hydrogen and
oxygen gas.
The only problem stopping development of safe HHO systems is the
fact that you can't control/constrain supplies
(finacial/political power) on something that falls from the sky.
Stan Redmond| 4.24.09 @ 2:59PM
In reply to CMC:
While voltaics may get more effecient we CAN NOT control the
amount of sunlight striking the earth. We CAN NOT control cloud
cover. A solar voltaic may capture 100% of the sun's energy but
at night or on a cloudy day, they are 100% useless. There is also
no way to store that energy on a realistic scale.
Marc Jeric| 4.24.09 @ 3:25PM
Nuclear power was killed by Carter, our "nukelar engineer", when
he placed a Sierra Club Lawyer and Massachussetts consumer
advocate on the Nuclear Regulatory Commission. He also killed the
Clinch River reprocessing plant. The three nuclear power
accidents were the following: 1) Browns Ferry fire was caused by
a union worker who left the flaming candle under the cable tray -
you see, work rules called fior lunch break and he did not have
time to finish utterly useless test of air flows between rooms
dictated by the NRC; 2) Three Mile Island reactor meltdown (this
should not be called an accident - no fly was hurt there, so it
was only equipment failure); another useless test dictated by the
NRC after only 8 weeks of operation of a brand new plant that had
passed all the tests already; union worker from a subcontractor
forgot to re-open the valves on the emergency cooling water
pumps; when the pressure relief valve got stuck open and the
reactor cooling water escaped, those pumps came on but hit those
closed valves - you see, union work rules called off the workers
at the time and so the valves stayed closed; 3) Chernobyl steam
explosion (it was not a nuclear reaction!) dispersed nuclear
material over the countryside. How come? Chernobyl design for 14
similar Soviet plants was one of the 14 American designs rejected
for inherent safety faults; but it was one stolen by the Soviet
spies Rosenbergs (was that their name - later executed) and
passed to the Soviets; the reason it was rejected by the
Americans was that at below the 20% power level the reactor
became unstable with a positive reactivity factor (in other words
tended to heat up uncontrollably); the Soviets used 14 reactors
of that type to produce both electricity and bomb material but
then had too many of them and wanted to pass some of them to
electricity production only. For that purpose and in order to
profit by western technology they submitted the Chernobyl plant
to western inspection. That inspection criticized the Russian
design for using ordinary marine diesels for emergency power
(those diesels needed 2 minutes to produce 100% power while
american special diesels took only 10 seconds); the Russians
protested that it was not necessary since the inertia of the main
turbine-generator upon shutdown will provide enough emergency
power while their diesels are coming up. The IAEA inspectors said
OK if the Russians could privide proof by a test. So the Russians
waited for a time of low electricity demand in Kiev one Sunday
night to perform that test. However the Kiev engineer told them -
No shutdown! Communist Party Congress is dancing, drinking,
celebrating long into the night! - and so the plant operators
held the reactor under that fateful 20% rating for several hours
- till 4 AM; as predicted by the Americans 40 years before, the
reactor entered into uncotrollable reactivity state and caused
steam explosion. Since the Russians saving money dispensed with
the containment structure which would have kept the damage within
it, the overheated reactor rods were carried by exploding steam
into the atmosphere. This is way to long - I will leave it to the
reader to form his own conclusions.

bernardo| 4.24.09 @ 6:14PM
I first thought the moderator should remove Matthews from this
post, since, after all, the man seems to be advocating or at
least salivating over the prospect of genocide of the entire
human race, which includes many women and minorities. However, on
second thought he serves a valuable purpose. Whenever you think
the "greens" are all merely misguided idealists (as some of them
really are), think of Matthews. Conservatives like to call the
radical enviros watermelons, for green on the outside and red on
the inside. However even that is too kind for the extreme wing of
the movement. Marx did not want to destroy a majority of the
human race or even to reduce it to prehistoric savagery. Many
extremist greens want the latter, and quite a few are intrigued
by the former. So laugh at Matthews and call him a moron if you
like, but remember. He stands for something, and he is not alone.
Dave Lincoln| 4.24.09 @ 10:44PM
Mr. Tucker,
I agree with you on you general principles, and I have before on
your articles about energy. However, as an engineer, I see enough
mistakes in your article to see you as an "innumerate
journalist", and this tempts me to dismiss anything else you have
to say.
The difference between energy and power is very important, Mr.
Tucker. You confuse it a lot! Power is the rate of transfer of
energy - the units are different, and when I read one instead of
the other, it makes me lose respect for your writing.
Here are some mistakes that I see (you could easily have talked
to a Mech. Engineer to get him to review your article before
publication, and save me from all this writing):
1) "A liter of gasoline, for example, can produce 9.7 kilowatt-
hours (kWh) of power..." NO! 9.7 kW-hr of ENERGY. OK, at that
point, I figure, just a typo.
2) "Anthracite coal produces 9.4 kWh, liquid natural gas 7.2 kWh,
methanol 4.6 kWh, and wood around .5–.9 kWh, depending on its
moisture content." ??? huh? per what? Per liter?, but that can't
apply to wood. Per mass, perhaps? Don't know, you seem very
innumerate here, Mr. Tucker.
3) "Sunup to sundown, the sun's rays shed about 400 watts per
square meter of ground in the United States". OK, obviously the
solar incidence is varying through the day. So, do you mean total
ENERGY? In that case, you probably meant 400 kWhr per day per
sq-m. You could have said average of 35-50 or so W/sq-m during
the day, to put it in terms of POWER. You've got it totally
confusing.
4) New topic. You say the constant, c (speed of light) squared is
"on the order of one quadrillion". One Quadrillion what's, Mr.
Tucker? Good grief, give me some units, dude! Without units,
number mean nothing. Why don't you just say 12 next time ( the
speed of light square does = 12 in SOMEBODY's units). If you're
gonna be all SI on us, use 9 x 10**16 m-sq/s-sq as your c**2, as
that way you can deal with mass in kg, and energy in Joules (N-m,
or kg-m-sq/s-sq) Yeah, you get a lot of freaking energy from the
loss of a kg of matter, you betcha.
5) Aha, you corrected Earth's "crust" to Earth's "core", per
previous comment. Very good.
OK, sorry, but these kind of mistakes bug me, but also will take
away from your message (not to "people" like the
perl-Dave-Matthews-script, or any lefty, as there is never much
understanding anyway.) You are quite correct that these Silicon
Valley types are quite idiotic when they think they have a better
way. Many of these people are very good computer people, but none
of them are real engineers, and that's what it takes to solve a
physical problem. It reminds me of that geek Bezos from Amazon
thinking he is somehow enlightened about reaching space. Stick to
books, Jeff; that's your "space".
OK, I hope you don't take this the wrong way, Mr. Tucker. If you
do reply, I will be glad to send you a way to reach me so you can
get a quick edit next time - I am not saying this as snark - I
would like to help.
Ralph Woods| 4.25.09 @ 12:01AM
In reply to Dave Lincoln, I think you are missing the point of
the article by Mr. Tucker. He is simply trying to explain the
order of magnitude of the energy sources available to mankind. As
it is, probably less than 5% of the population could understand
what he is writing about. Any type of math or physics is Greek to
most people. As evidence I suggest you look to the "smartest"
members of congress who calculated a person making $ 30,000.00
per year could buy a $ 400,000.00 house at 10% interest and
actually pay the mortgage payments.

Mr. Matthews:
Let's put this into perspective: more people have died in the
back seat of Ted Kennedy's car than have died from commercial
nuclear power here in the US.
Shyster| 4.25.09 @ 6:04AM
Even were his allegations correct(and, as usual, they're
not)
Matthews offers no viable argument against Tucker's points. Small
wonder
since Matthews is an ignoramus, par excellence.
It's necessary, though not agreeable, to respond
to a moron like Matthews precisely because there are
idiots that actually believe the claptrap he spews.
Matthews, care to elaborate on the "lingering curse of
radioactive pollution produced by the nuclear industry."?
Where, exactly, does that "radioactive pollution" exist, aside
from your wild imaginings?
Civilization has always been driven by technological advances,
not Malthusian nonsense.
Frankly, David, you're well beyond "ignorant incompetence".
By the way, David, it's spelled, "racist", not "reacist".
In case you hadn't bothered to read the actual science,
David,
there's no case for suggesting the world population will reach 9
billion anytime soon.
As civilization advances, the trend is toward diminished
population, not more.
Your 9 billion estimates have no statistical basis. Of course,
having a background in statistics, isn't one of your forte's.
Any survey of history would inform your fevered brain, that
civilization has advanced in direct
proportion to it's reliance and utilization of energy.
It's obvious you're a fervent adherent of Paul Ehrlich, who has
been
wrong about everything related to population, supply,etc...
Get a brain fellow...
Your remarks about hydrogen production reveal a similar ignorance
of basic science.
Nuclear power is a simple solution to a complex problem. I can
certainly
understand your inability to understand both science and common
sense.
Nuclear power is desperation? No, your attempts to discredit it
are signs of desperation and ignorance.
Contrary to your assertions(actually, idiot ramblings)
technological
advances have always driven the advancement of civilization.
There's
nothing "dead end" about it. The drivel you spew is the dead end
to
civilization.
You actually listen to Keith Olberman? And you have the
termerity
to call conservatives, dumb? A man who lies about attending an
Ivy League
school who majored in communication at an agricultural college?
And conservatives
are dumb?
By the way, idiot child, the earth cooled for thirty years while
CO2 emmisions rose.
And incidentally, there's been no global warming in ten years
despite
increases in CO2? Who's the idiot?
David, you're a certified idiot and ignoramus.
Check back when you actually have facts in support of your
silly
arguments.
Final question: doesn't it bother you being an uneducated,
ignorant
Bozo? Oh, I forgot, you worship another uneducated, ignorant
Bozo, Al Gore.
(ever notice how Gore became a multi-millionaire selling carbon
credits?)

"Humans don't live off electricity."
Actually, we do. We live of the electricity our bodies generate
for such things as muscle movement (try moving blood around
without the muscle contractions of your heart, contractions
powered AND regulated by electricity), we live off the
electricity our neurons generate when we have a thought (have you
EVER though about that?), and we live off the electricity our
very cells generate in the mitochondria located in every cell in
our body. Since electricity is so vital to our very life
processes (as it is the most efficient way to transport energy,
which is why life utilizes it), why should our cultures and
societies use electricity as well? After all, the generation,
distribution, and consumption of electricity is NATURAL. Ignoring
this fact is what will cause out population to collapse.
BTW, I'm STILL waiting for the population collapse that was
predicted 40 years ago, a prediction that claimed that the words
couldn't sustain a human population of 3 billion. We're now at 6
billion and counting, so where's the Great Extinction?
Richard Baker| 4.25.09 @ 9:57AM
The thrust of the article is that the energy being searched for
exists not where all the lefties say it must be but where it is.
To the engineers who decry a certain unitless form of
explanation: remember that most of the population doesn't even
understand the broad basis for the use of the atom as a source of
power due to a defective teaching of even high school science.
Case in point, I taught science at a local Florida high school in
2000 to 9-10th graders and a student argued with me that electric
cars would eliminate the need for coal/oil power plants. When I
asked him how would the electric cars be re-charged, he said that
you'd just plug them into a wall socket. When I further asked
from where the power for the sockets was derived, he said POWER-
and stopped in mid word as the light bulb went on. As I tried to
explain Conservation of Energy, my class looked at me as if I was
speaking of the secret of the universe. That is why the article
is written the way it is.

Re:Lincoln: Some of what you said is reasonable but I think "400

As far as Mr. Tucker I am never sure what to think. He always
spends a huge mass of his articles on a razzle dazzle of
marginally relevant scientific facts. Granted greenies do this
too; so if he were writing in a publication for the
pseudosophisticated, or frankly ignorant, such as the NY Times,
this would make a lot of sense. However I expect more
sophisticated Spectator readers to understand that e=mc2 matters
only as an extremely far off theoretical upper limit, ie, not
much at all. What matters in actual practical practice is how
much energy can be economically extracted, and Mr. Tucker spends
extremely little of his time on this point.
Spectator readers are also sophisticated enough to know that if
the greenie razzle dazzle were true, then the "renewables" would
be economically efficient and would therefore not require
government coercion to get people to adopt; so, except as a
talking point to discuss with your less sophisticated friends who
imagine the NY Times to be intelligent - I don't see the point in
using up a lot of article space refuting it.
If nuclear power is the most efficient then what government
coercion is preventing its adoption? That's the question I would
like answered.

I actually considered going into nuclear engineering in the early
60's as I was a physics major in college and prettydamn good at
it.. Glad I didn't as the industry made a complete disaster of it
with all the fragmented approaches that were taken. You have to
give the French credit for one thing they put a concentrated
effort into their nuclear program and it has paid of handsomely
for them. They now lead the world in technology and probably will
build most of the new reactors that are being or will be built in
countries all around the world except the USA.
mike| 4.26.09 @ 1:43AM
first of all, tucker was foolish in using estein theory of
relativity as symbolic form, and wrote it like an inexpierenced
child would. the correct formula as written is E= mc^2, this
oversight is laughable. further more those coparimg other
countries to America fail to mention their populations, france
has significanly less individuals than the United States. that
means what would work for them probably would not work for us.
further more nuclear power is a renewable resource, it again
requires a seperate fuel source that contrary to popular claims
is not reclaimed through reprocessing- only 95% is meaning that
eventually the rods will become useless. in addition, the plants
are an accident wating to happen given the risks for nuclear
meltdown, terrorist targetting, and the fact that nuclear power
is one of the largest causes of outsourcing known to man. it is
very hard to outsource green energy due to it's natural state.
while nuclear energy is much more effienct than fossilfuels, it
is not the great tool tucker makes it out to be.

nuclear meltdown, terrorist targetting," Did you get your
knowledge of nuclear energy from the movie China Syndrome ? Have
you ever been in a large scale chemical plant or a chemical
weapons facility? If the reprocessing process is so ineffective
as you suggest why do the French pour so much effort into it and
why are they reprocessing nuclear warheads for the "fuel"? A bit
more complicated than I think you understand.

Dave Lincoln: '3) "Sunup to sundown, the sun's rays shed about
400 watts per square meter of ground in the United States". OK,
obviously the solar incidence is varying through the day. So, do
you mean total ENERGY? In that case, you probably meant 400 kWhr
per day per sq-m. You could have said average of 35-50 or so
W/sq-m during the day, to put it in terms of POWER. You've got it
totally confusing.'
No, he meant an average of 400 W/m^2 (9.6 kWh/m^2 per day). Which
is rounding up, but there's a big chunk of the SW US that
receives more than 300 W/m^2 (7.2 kWh/m^2/day).

Hmm, I think I missed something here. Only 95% of the fuel is
recovered? That high? Wow.
And no, I don't think we should make decisions based on what is
easy to outsource. If the point of an energy source is to provide
useless, parasitic make-work jobs then I suggest we use the
superior energy source and then just hand the money to the people
who would otherwise have gotten the make-work jobs. We're better
off- we have a superior energy source; they're better off - they
get the money but don't have to work; everybody wins.
If anybody detected sarcasm - yeah it was there. There are very
few groups I respect less than those who want the government not
just to point guns at other people and force them to hand over
money - but for the government to force others to pretend they
are earning the money.

First I wish to post a correction to a # in the article:
"Sunup to sundown, the sun's rays shed about 400 watts per square
meter of ground in the United States."
Actually, the average is 1000 watts per square meter. (this comes
from my own data from experiments in college in Illinois &
from the data of other experimenters)
I'm an engineer, and from my perspective, ALL energy sources and
storage techniques have their proper place/application. There is
no one solution.
On a National scale, and for some private, but grand projects, we
need nuclear power, period -- end of story. On smaller scales
solar and wind are great. Solar is even good at a medium scale
(towns up to 100,000 people), especially when it's not strictly
PV, put utilizes various thermal utilizeations like solar
stirling engines which allow for thermal storage to run the
system when the sun don't shine (combines nicely with geothermal
too!)
Anyway, we already have all the "solutions" to continue to run a
civilized technological society, that is also "in tune with the
environment" . . . to use a cliche, it's simply a matter of doing
it.
Lynn H.| 4.27.09 @ 11:20PM
Don't forget the energy required to manufacture solar panels.
Using current technology, it takes an average of 16 years to get
to the point where a solar panel has generated as much
electricity as was required to manufacture it. Assuming a
lifespan of 20 years, that means the net energy gained is only
20% of what it produces.
Scientists are researching more efficient ways to make solar
panels, but in the meantime they don't make much sense unless you
live in a very sunny region.

No, 1000 W/m^2 is about the *maximum* you can get on the Earth's
surface, reduced from the 1370 you can get above the Earth's
atmosphere. The *average* is lower still, because half the Earth
is on the night side, and the rest is tilted at various angles to
the sun.

CMElec| 5.18.09 @ 10:58PM
The energy source that ushered in the 20th century is wholly
inadequate to the tasks required of it in the 21st. That will
soon become more clearly evident. The single reason for the
existence of our highly technological society is energy;
inexpensive and in quantity. Without it we will have to shoulder
the plow along with animals pulling most of the load. That won't
happen, trust me. It will be nukes, there is no other option as
available or scalable. Put all of the arguments to rest and deal
with what is real.
The fact is that installing solar panels for your home or
business can cut your electric bill to $0 today.
The typical American homeowner won't pay attention to the
science, but they will pay attention to their monthly expenses.
If a product can save them money, they will take advantage. In
this case, take your monthly electric bill and multiply by 12
months, then again by 25 years to determine how much you will
spend on traditional utility-generated electricity during the
typical life of a solar panel system. Then depending on your
energy needs, compare this to the $5,000 to $25,000 cost to
install solar panels.
For example, if you spend $200 per month for electricity, then
you will spend $81,979 over 25 years, including a low annual
price inflation rate of 2.5%. No matter how you calculate it, you
will save money with a $5,000 to $25,000 solar panel system. Some
so-called experts will say the cost per kilo-watt (kW) for
traditional utility energy is less than the cost per kW of solar.
Remember, you can pay the utility for 25 years, with annual price
increases, or you can pay 80% less with solar power.
If you are worried about the upfront cost for solar panels, there
are many financing and leasing programs available to homeowners
with good credit. Some loans are tax-deductible too.
If you want to do something about this today, then visit FreeCleanSolar.com to search a
nationwide network of 500 local solar installers. You can also
find information about state solar rebates, federal tax credits,
solar financing and leasing, system costs and the benefits of
going solar. The bottom line is that many homeowners and business
owners can afford solar power today.
Hmm communism another delicate issue that causes dispute even
between people that share the same opinion.
Loved the article and do agree with George's interpretation of
it.
I come from a communist country so I guess my opinion is a bit
blurred, but to be honest I believe that every social system has
problems whereby the people suffer
My company offers solar solutions to homeowners as part of a
energy saving package for their homes. To date, we have had no
homeowner buy a solar system because the cost benefit ration just
isn't there.

And ...
* No coal power.
If humankind cannot survive without electricity our species will go extinct. Since humankind cannot survive without electricity, our species will certainly go extinct.

David Mathews’ solution is that we rely on bicycles made of hemp for our transportation needs, but doing so would require a significant downsizing in the world’s population. While I’m sure that he is willing and able to assist in the necessary reductions with great enthusiasm, I think that it’s kindler and gentler to build nukes at breakneck pace to sate the population’s growing stationary energy needs. Moreover, over a short time excess nuke capacity could generate hydrogen, a medium suitable for fueling our mobile transportation needs.
So the contrast is simply that Mr. Mathews wants to drive humanity back to the caves and savannahs while more thoughtful folks seek to deploy the harnessed atom in a manner that engenders human prosperity. And he’s the progressive?

David Mathews| 4.24.09 @ 7:57AM
Hello Mike,
* "David Mathews’ solution is that we rely on bicycles made of hemp for our transportation needs, but doing so would require a significant downsizing in the world’s population."
The human population will peak at approximately 9 billion and collapse in a manner similar to the housing bubble's collapse, except with much more horrific implications. That's just reality.
* " While I’m sure that he is willing and able to assist in the necessary reductions with great enthusiasm, I think that it’s kindler and gentler to build nukes at breakneck pace to sate the population’s growing stationary energy needs."
Humans don't live off electricity. The food and water problems will overwhelm humankind in the decades ahead and no amount of nuclear power will solve those problems.
* "Moreover, over a short time excess nuke capacity could generate hydrogen, a medium suitable for fueling our mobile transportation needs. "
Perhaps there is a nuclear powered perpetual motion machine, too. The moon might also be made of green choose, too.
* "So the contrast is simply that Mr. Mathews wants to drive humanity back to the caves and savannahs while more thoughtful folks seek to deploy the harnessed atom in a manner that engenders human prosperity. And he’s the progressive? "
Nuclear power isn't going to save civilization. Nuclear power is desperation ... sort of like the intensive care unit for Terry Schiavo.

the problem with nuclear "waste" was created when Jimmy Carter decided that reprocessing nuclear fuel rods was not going to be allowed. Commercial fuel rods are only about 3% enriched uranium, while nukie sub reactor rods are considerably higher. France supplies about 70% of their power with nuclear, and reprocess the rods. It is, in simple terms, recovering the uranium from fuel rods that that has not been consumed and putting that in new rods. It is my understanding the total amount of French "waste" has a foot print of about 2000 sq. ft. The US nuclear industry has been paying the federal gov't for years to support the Yucca Mountain facility, while Congress (think Harry Reid) has been intentionally dragging their feet to get it finished. Start reprocessing the fuel, and the amount of waste would be miniscule in comparison to what it is today. As for Dave Mathews comments---he is fortunate to live in a country that has the 1st amendment that protects his right to express his opinion

No problem. DM, your claims were made by many others since the '60's - dire predictions of impending doom and population crash. They have all been wrong - wrong then and wrong now.
Trust me if solar could be made to work efficiently, it would not require one government subsidy.
DaveS| 4.24.09 @ 10:01AM
Tucker got one thing kind of wrong, but he may have done so for reasons of simplicity: when uranium and thorium decay, they produce the energy he speaks of at the earth's core. When uranium (-233 or -235) fissions you get about 160 MeV in fission fragment kinetic energy with the rest is neutrons and gamma. The thorium is useful when bred to U-233. Other than that, the facts (Mr. Matthews) speak for themselves. God has created a pretty marvelous energy source - born solar and discovered terrestrial. Everything else pales or is pipe dream.
dcd| 4.24.09 @ 10:26AM
Government subsidies are the problem. Except for basic research the government should get out of the game; no direct or indirect subsidies for ethanol, solar, hydrocarbons, or nuclear. An industry should cover its own expenses, pay full market price for what it takes, and persuade the locals that it is an acceptable neighbor without the federal government's pocketbook or muscle.

I am wondering here if this doesn't scare the EW's, Environmental Wacko's, as much as attempting to actually use solar power? They are screaming about trashing the Mojave desert to try major wind and solar plants, they complain about endangering birds and migration patterns at existing wind plants in California and obviously the technology for safe nuclear is already here and has been.
Using the technology from the next generation reactors and producing a stable cost effective source of hydrogen power for vehicles, and we laugh at the world still using something quaint like oil for vehicles and coal for power.
With so many upsides, the only downside is the threat of EW's. It just provides further proof rational debate is non existent when it comes to the environment. It's not the environment any more, it's control as has been pointed out in many other articles.
Let's hope reason will at some point prevail if enough of US keep hammering away at politicians of both sides until they get the message.

We already use the most efficient and safe ‘terrestrial energy’…
“A liter of gasoline, for example, can produce 9.7 kilowatt- hours (kWh) of power—probably the densest form of chemical energy we will ever encounter.”
…oil. Petroleum and its derivatives natural gas and coal originate deep under the earth’s crust/upper mantle from iron oxide (earth has an iron core), calcium carbonate (marble) with a touch of water at high pressures and heat. (http://www.gasresources.net/AlkaneGenesis.htm) The sun and plant life has/had nothing to do with the creation of oil. The laws of thermodynamics prohibit low energy material (cold water/bio-mass) to magically become high energy material (hot water/petroleum).

To JamesD:
The Navy has a program for decommissioning and recycling nuclear powered naval vessels, see http://en.wikipedia.org/wiki/Ship-Submarine_recycling_program
The nuclear fuel contained in these reactors is removed and re-processed. The reactor compartments are then buried at Hanford, WA.
Fiat lux| 4.24.09 @ 2:43PM
The progression of high carbon fuels to low carbon fuels has been happening for the past 140 plus years. Hydrogen/Carbon ratios: Wood – 1/10, coal – 1/2, oil – 2/1, natural gas – 4/1
The future of energy follows this progression to a carbonless fuel. H20. Water. Hydrogen. Not the hydrogen cell. Hydrogen and oxygen gas.
The only problem stopping development of safe HHO systems is the fact that you can't control/constrain supplies (finacial/political power) on something that falls from the sky.

In reply to CMC:
While voltaics may get more effecient we CAN NOT control the amount of sunlight striking the earth. We CAN NOT control cloud cover. A solar voltaic may capture 100% of the sun's energy but at night or on a cloudy day, they are 100% useless. There is also no way to store that energy on a realistic scale.

Nuclear power was killed by Carter, our "nukelar engineer", when he placed a Sierra Club Lawyer and Massachussetts consumer advocate on the Nuclear Regulatory Commission. He also killed the Clinch River reprocessing plant. The three nuclear power accidents were the following: 1) Browns Ferry fire was caused by a union worker who left the flaming candle under the cable tray - you see, work rules called fior lunch break and he did not have time to finish utterly useless test of air flows between rooms dictated by the NRC; 2) Three Mile Island reactor meltdown (this should not be called an accident - no fly was hurt there, so it was only equipment failure); another useless test dictated by the NRC after only 8 weeks of operation of a brand new plant that had passed all the tests already; union worker from a subcontractor forgot to re-open the valves on the emergency cooling water pumps; when the pressure relief valve got stuck open and the reactor cooling water escaped, those pumps came on but hit those closed valves - you see, union work rules called off the workers at the time and so the valves stayed closed; 3) Chernobyl steam explosion (it was not a nuclear reaction!) dispersed nuclear material over the countryside. How come? Chernobyl design for 14 similar Soviet plants was one of the 14 American designs rejected for inherent safety faults; but it was one stolen by the Soviet spies Rosenbergs (was that their name - later executed) and passed to the Soviets; the reason it was rejected by the Americans was that at below the 20% power level the reactor became unstable with a positive reactivity factor (in other words tended to heat up uncontrollably); the Soviets used 14 reactors of that type to produce both electricity and bomb material but then had too many of them and wanted to pass some of them to electricity production only. For that purpose and in order to profit by western technology they submitted the Chernobyl plant to western inspection. That inspection criticized the Russian design for using ordinary marine diesels for emergency power (those diesels needed 2 minutes to produce 100% power while american special diesels took only 10 seconds); the Russians protested that it was not necessary since the inertia of the main turbine-generator upon shutdown will provide enough emergency power while their diesels are coming up. The IAEA inspectors said OK if the Russians could privide proof by a test. So the Russians waited for a time of low electricity demand in Kiev one Sunday night to perform that test. However the Kiev engineer told them - No shutdown! Communist Party Congress is dancing, drinking, celebrating long into the night! - and so the plant operators held the reactor under that fateful 20% rating for several hours - till 4 AM; as predicted by the Americans 40 years before, the reactor entered into uncotrollable reactivity state and caused steam explosion. Since the Russians saving money dispensed with the containment structure which would have kept the damage within it, the overheated reactor rods were carried by exploding steam into the atmosphere. This is way to long - I will leave it to the reader to form his own conclusions.

I first thought the moderator should remove Matthews from this post, since, after all, the man seems to be advocating or at least salivating over the prospect of genocide of the entire human race, which includes many women and minorities. However, on second thought he serves a valuable purpose. Whenever you think the "greens" are all merely misguided idealists (as some of them really are), think of Matthews. Conservatives like to call the radical enviros watermelons, for green on the outside and red on the inside. However even that is too kind for the extreme wing of the movement. Marx did not want to destroy a majority of the human race or even to reduce it to prehistoric savagery. Many extremist greens want the latter, and quite a few are intrigued by the former. So laugh at Matthews and call him a moron if you like, but remember. He stands for something, and he is not alone.
Dave Lincoln| 4.24.09 @ 10:44PM
Mr. Tucker,
I agree with you on you general principles, and I have before on your articles about energy. However, as an engineer, I see enough mistakes in your article to see you as an "innumerate journalist", and this tempts me to dismiss anything else you have to say.
The difference between energy and power is very important, Mr. Tucker. You confuse it a lot! Power is the rate of transfer of energy - the units are different, and when I read one instead of the other, it makes me lose respect for your writing.
Here are some mistakes that I see (you could easily have talked to a Mech. Engineer to get him to review your article before publication, and save me from all this writing):
1) "A liter of gasoline, for example, can produce 9.7 kilowatt- hours (kWh) of power..." NO! 9.7 kW-hr of ENERGY. OK, at that point, I figure, just a typo.
2) "Anthracite coal produces 9.4 kWh, liquid natural gas 7.2 kWh, methanol 4.6 kWh, and wood around .5–.9 kWh, depending on its moisture content." ??? huh? per what? Per liter?, but that can't apply to wood. Per mass, perhaps? Don't know, you seem very innumerate here, Mr. Tucker.
3) "Sunup to sundown, the sun's rays shed about 400 watts per square meter of ground in the United States". OK, obviously the solar incidence is varying through the day. So, do you mean total ENERGY? In that case, you probably meant 400 kWhr per day per sq-m. You could have said average of 35-50 or so W/sq-m during the day, to put it in terms of POWER. You've got it totally confusing.
4) New topic. You say the constant, c (speed of light) squared is "on the order of one quadrillion". One Quadrillion what's, Mr. Tucker? Good grief, give me some units, dude! Without units, number mean nothing. Why don't you just say 12 next time ( the speed of light square does = 12 in SOMEBODY's units). If you're gonna be all SI on us, use 9 x 10**16 m-sq/s-sq as your c**2, as that way you can deal with mass in kg, and energy in Joules (N-m, or kg-m-sq/s-sq) Yeah, you get a lot of freaking energy from the loss of a kg of matter, you betcha.
5) Aha, you corrected Earth's "crust" to Earth's "core", per previous comment. Very good.
OK, sorry, but these kind of mistakes bug me, but also will take away from your message (not to "people" like the perl-Dave-Matthews-script, or any lefty, as there is never much understanding anyway.) You are quite correct that these Silicon Valley types are quite idiotic when they think they have a better way. Many of these people are very good computer people, but none of them are real engineers, and that's what it takes to solve a physical problem. It reminds me of that geek Bezos from Amazon thinking he is somehow enlightened about reaching space. Stick to books, Jeff; that's your "space".
OK, I hope you don't take this the wrong way, Mr. Tucker. If you do reply, I will be glad to send you a way to reach me so you can get a quick edit next time - I am not saying this as snark - I would like to help.
Ralph Woods| 4.25.09 @ 12:01AM
In reply to Dave Lincoln, I think you are missing the point of the article by Mr. Tucker. He is simply trying to explain the order of magnitude of the energy sources available to mankind. As it is, probably less than 5% of the population could understand what he is writing about. Any type of math or physics is Greek to most people. As evidence I suggest you look to the "smartest" members of congress who calculated a person making $ 30,000.00 per year could buy a $ 400,000.00 house at 10% interest and actually pay the mortgage payments.

Mr. Matthews:
Let's put this into perspective: more people have died in the back seat of Ted Kennedy's car than have died from commercial nuclear power here in the US.
Shyster| 4.25.09 @ 6:04AM
Even were his allegations correct(and, as usual, they're not)
Matthews offers no viable argument against Tucker's points. Small wonder
since Matthews is an ignoramus, par excellence.
It's necessary, though not agreeable, to respond
to a moron like Matthews precisely because there are
idiots that actually believe the claptrap he spews.
Matthews, care to elaborate on the "lingering curse of radioactive pollution produced by the nuclear industry."?
Where, exactly, does that "radioactive pollution" exist, aside from your wild imaginings?
Civilization has always been driven by technological advances, not Malthusian nonsense.
Frankly, David, you're well beyond "ignorant incompetence".
By the way, David, it's spelled, "racist", not "reacist".
In case you hadn't bothered to read the actual science, David,
there's no case for suggesting the world population will reach 9 billion anytime soon.
As civilization advances, the trend is toward diminished population, not more.
Your 9 billion estimates have no statistical basis. Of course, having a background in statistics, isn't one of your forte's.
Any survey of history would inform your fevered brain, that civilization has advanced in direct
proportion to it's reliance and utilization of energy.
It's obvious you're a fervent adherent of Paul Ehrlich, who has been
wrong about everything related to population, supply,etc...
Get a brain fellow...
Your remarks about hydrogen production reveal a similar ignorance of basic science.
Nuclear power is a simple solution to a complex problem. I can certainly
understand your inability to understand both science and common sense.
Nuclear power is desperation? No, your attempts to discredit it are signs of desperation and ignorance.
Contrary to your assertions(actually, idiot ramblings) technological
advances have always driven the advancement of civilization. There's
nothing "dead end" about it. The drivel you spew is the dead end to
civilization.
You actually listen to Keith Olberman? And you have the termerity
to call conservatives, dumb? A man who lies about attending an Ivy League
school who majored in communication at an agricultural college? And conservatives
are dumb?
By the way, idiot child, the earth cooled for thirty years while CO2 emmisions rose.
And incidentally, there's been no global warming in ten years despite
increases in CO2? Who's the idiot?
David, you're a certified idiot and ignoramus.
Check back when you actually have facts in support of your silly
arguments.
Final question: doesn't it bother you being an uneducated, ignorant
Bozo? Oh, I forgot, you worship another uneducated, ignorant Bozo, Al Gore.
(ever notice how Gore became a multi-millionaire selling carbon credits?)

Ray| 4.25.09 @ 9:54AM
"Humans don't live off electricity."
Actually, we do. We live of the electricity our bodies generate for such things as muscle movement (try moving blood around without the muscle contractions of your heart, contractions powered AND regulated by electricity), we live off the electricity our neurons generate when we have a thought (have you EVER though about that?), and we live off the electricity our very cells generate in the mitochondria located in every cell in our body. Since electricity is so vital to our very life processes (as it is the most efficient way to transport energy, which is why life utilizes it), why should our cultures and societies use electricity as well? After all, the generation, distribution, and consumption of electricity is NATURAL. Ignoring this fact is what will cause out population to collapse.
BTW, I'm STILL waiting for the population collapse that was predicted 40 years ago, a prediction that claimed that the words couldn't sustain a human population of 3 billion. We're now at 6 billion and counting, so where's the Great Extinction?
Richard Baker| 4.25.09 @ 9:57AM
The thrust of the article is that the energy being searched for exists not where all the lefties say it must be but where it is. To the engineers who decry a certain unitless form of explanation: remember that most of the population doesn't even understand the broad basis for the use of the atom as a source of power due to a defective teaching of even high school science. Case in point, I taught science at a local Florida high school in 2000 to 9-10th graders and a student argued with me that electric cars would eliminate the need for coal/oil power plants. When I asked him how would the electric cars be re-charged, he said that you'd just plug them into a wall socket. When I further asked from where the power for the sockets was derived, he said POWER- and stopped in mid word as the light bulb went on. As I tried to explain Conservation of Energy, my class looked at me as if I was speaking of the secret of the universe. That is why the article is written the way it is.

Re:Lincoln: Some of what you said is reasonable but I think "400 watts per meter squared" is fair enough, implicitly assuming he means the average power.
As far as Mr. Tucker I am never sure what to think. He always spends a huge mass of his articles on a razzle dazzle of marginally relevant scientific facts. Granted greenies do this too; so if he were writing in a publication for the pseudosophisticated, or frankly ignorant, such as the NY Times, this would make a lot of sense. However I expect more sophisticated Spectator readers to understand that e=mc2 matters only as an extremely far off theoretical upper limit, ie, not much at all. What matters in actual practical practice is how much energy can be economically extracted, and Mr. Tucker spends extremely little of his time on this point.
Spectator readers are also sophisticated enough to know that if the greenie razzle dazzle were true, then the "renewables" would be economically efficient and would therefore not require government coercion to get people to adopt; so, except as a talking point to discuss with your less sophisticated friends who imagine the NY Times to be intelligent - I don't see the point in using up a lot of article space refuting it.
If nuclear power is the most efficient then what government coercion is preventing its adoption? That's the question I would like answered.

I actually considered going into nuclear engineering in the early 60's as I was a physics major in college and prettydamn good at it.. Glad I didn't as the industry made a complete disaster of it with all the fragmented approaches that were taken. You have to give the French credit for one thing they put a concentrated effort into their nuclear program and it has paid of handsomely for them. They now lead the world in technology and probably will build most of the new reactors that are being or will be built in countries all around the world except the USA.
mike| 4.26.09 @ 1:43AM
first of all, tucker was foolish in using estein theory of relativity as symbolic form, and wrote it like an inexpierenced child would. the correct formula as written is E= mc^2, this oversight is laughable. further more those coparimg other countries to America fail to mention their populations, france has significanly less individuals than the United States. that means what would work for them probably would not work for us. further more nuclear power is a renewable resource, it again requires a seperate fuel source that contrary to popular claims is not reclaimed through reprocessing- only 95% is meaning that eventually the rods will become useless. in addition, the plants are an accident wating to happen given the risks for nuclear meltdown, terrorist targetting, and the fact that nuclear power is one of the largest causes of outsourcing known to man. it is very hard to outsource green energy due to it's natural state. while nuclear energy is much more effienct than fossilfuels, it is not the great tool tucker makes it out to be.

Mike, what does population size have to do with French success at generating 70-80% of their electrical needs? I'm curious. "the plants are an accident wating to happen given the risks for nuclear meltdown, terrorist targetting," Did you get your knowledge of nuclear energy from the movie China Syndrome ? Have you ever been in a large scale chemical plant or a chemical weapons facility? If the reprocessing process is so ineffective as you suggest why do the French pour so much effort into it and why are they reprocessing nuclear warheads for the "fuel"? A bit more complicated than I think you understand.

No, he meant an average of 400 W/m^2 (9.6 kWh/m^2 per day). Which is rounding up, but there's a big chunk of the SW US that receives more than 300 W/m^2 (7.2 kWh/m^2/day).

Hmm, I think I missed something here. Only 95% of the fuel is recovered? That high? Wow.
And no, I don't think we should make decisions based on what is easy to outsource. If the point of an energy source is to provide useless, parasitic make-work jobs then I suggest we use the superior energy source and then just hand the money to the people who would otherwise have gotten the make-work jobs. We're better off- we have a superior energy source; they're better off - they get the money but don't have to work; everybody wins.
If anybody detected sarcasm - yeah it was there. There are very few groups I respect less than those who want the government not just to point guns at other people and force them to hand over money - but for the government to force others to pretend they are earning the money.

First I wish to post a correction to a # in the article:
"Sunup to sundown, the sun's rays shed about 400 watts per square meter of ground in the United States."
Actually, the average is 1000 watts per square meter. (this comes from my own data from experiments in college in Illinois & from the data of other experimenters)
I'm an engineer, and from my perspective, ALL energy sources and storage techniques have their proper place/application. There is no one solution.
On a National scale, and for some private, but grand projects, we need nuclear power, period -- end of story. On smaller scales solar and wind are great. Solar is even good at a medium scale (towns up to 100,000 people), especially when it's not strictly PV, put utilizes various thermal utilizeations like solar stirling engines which allow for thermal storage to run the system when the sun don't shine (combines nicely with geothermal too!)
Anyway, we already have all the "solutions" to continue to run a civilized technological society, that is also "in tune with the environment" . . . to use a cliche, it's simply a matter of doing it.
Lynn H.| 4.27.09 @ 11:20PM
Don't forget the energy required to manufacture solar panels. Using current technology, it takes an average of 16 years to get to the point where a solar panel has generated as much electricity as was required to manufacture it. Assuming a lifespan of 20 years, that means the net energy gained is only 20% of what it produces.
Scientists are researching more efficient ways to make solar panels, but in the meantime they don't make much sense unless you live in a very sunny region.

No, 1000 W/m^2 is about the *maximum* you can get on the Earth's surface, reduced from the 1370 you can get above the Earth's atmosphere. The *average* is lower still, because half the Earth is on the night side, and the rest is tilted at various angles to the sun.

The energy source that ushered in the 20th century is wholly inadequate to the tasks required of it in the 21st. That will soon become more clearly evident. The single reason for the existence of our highly technological society is energy; inexpensive and in quantity. Without it we will have to shoulder the plow along with animals pulling most of the load. That won't happen, trust me. It will be nukes, there is no other option as available or scalable. Put all of the arguments to rest and deal with what is real.
FreeleanSolar| 7.22.09 @ 3:16PM
The fact is that installing solar panels for your home or business can cut your electric bill to $0 today.
The typical American homeowner won't pay attention to the science, but they will pay attention to their monthly expenses. If a product can save them money, they will take advantage. In this case, take your monthly electric bill and multiply by 12 months, then again by 25 years to determine how much you will spend on traditional utility-generated electricity during the typical life of a solar panel system. Then depending on your energy needs, compare this to the $5,000 to $25,000 cost to install solar panels.
For example, if you spend $200 per month for electricity, then you will spend $81,979 over 25 years, including a low annual price inflation rate of 2.5%. No matter how you calculate it, you will save money with a $5,000 to $25,000 solar panel system. Some so-called experts will say the cost per kilo-watt (kW) for traditional utility energy is less than the cost per kW of solar. Remember, you can pay the utility for 25 years, with annual price increases, or you can pay 80% less with solar power.
If you are worried about the upfront cost for solar panels, there are many financing and leasing programs available to homeowners with good credit. Some loans are tax-deductible too.
If you want to do something about this today, then visit FreeCleanSolar.com to search a nationwide network of 500 local solar installers. You can also find information about state solar rebates, federal tax credits, solar financing and leasing, system costs and the benefits of going solar. The bottom line is that many homeowners and business owners can afford solar power today.
