The Energy Spectator
Unscientific American
Scientific American used to be a great magazine — before it became intellectually unsustainable.
Scientific American used to be a great magazine but like any publishing venture headquartered in New York, it has gradually drifted into liberal never-never-land. .
Over the years the magazine has run several lead stories encouraging complete nuclear disarmament. At one point it had O.J. Simpson’s attorney explaining why DNA technology would never be accurate. Now it’s become a shameless, uncritical cheerleader for a world run on renewable energy.
This month’s cover story, “A Plan for a Sustainable Future: How to get all energy from wind, water and solar power by 2030,” is a prime example. Authors Mark Z. Jacobsen and Mark A. Delucchi are respectively, a professor of civil and environmental engineering at Stanford and a research scientist at UC Davis — which makes you wonder what’s going on in academia these days. The article is so full of half-truths, absurd omissions and blue-sky fantasy that it is hard to know where to begin.
The authors premise is this: In order to free ourselves from fossil fuels and nuclear power, the authors postulate, all we need to do over the next 20 years is build the following:
• 490,000 tidal turbines of 1 megawatt apiece (<1 percent of which are now in place).
• 5,350 geothermal plants of 100 MW (< 2 percent in place).
• 900 hydroelectric dams of 1300 MW (70 percent in place),
• 3,800,000 windmills of 5 MW (1 percent in place).
• 720,000 wave converters (ocean turbines driven by waves rather than the tide), 0.75 MW (< 1 percent in place).
• 1,700,000,000 rooftop solar voltaic systems, 0.003 MW (< 1 percent in place).
• 49,000 solar thermal plants (mirror arrays that heat a fluid), 300 MW (< 1 percent in place).
• 40,000 photovoltaic power plants (sunlight directly into electricity), 300 MW (<1 percent in place).
That would make a nice stimulus package, wouldn’t it? Let’s hope Congress doesn’t take this too seriously. Offhand, I would say that if we undertook one-tenth of these tasks over the next twenty years we would be very ambitious. Even then, the authors have had to do a lot of fudging. For example:
• 900 hydroelectric dams, 1300 MW, 70 percent in place. There are only 94 dams in the whole world that produce more than 1300 MW, eleven of them in the United States. Even Glen Canyon (1296 MW) does not quite qualify. Around the world there are few dam sites left untamed. Even building 70 more dams of this size – let alone 800 — is unlikely.
• 3,800,000 windmills, 5 MW, <1 percent in place. The largest windmills now designed generate 3 MW. These are “the length of a football field,” as President Obama recently mentioned. A windmill generating 5 MW would probably be the length two football fields and stand 80 stories high. Imagine the landscape covered with 3 million these.

Yea. I picked up some of these from the library where you can place your old magazines on a rack for anybody to take. I took about six of them; read two and threw the rest into the trash can where they belonged.
Useless magazine for fact gathering.
E. Patrick Mosman| 10.28.09 @ 8:03AM
Scientific American initiated a practice of scientific censorship when it attacked not only Mr.Bjorn Lomborg's "the skeptical environmentalist", but Mr. Lomborg personally and then refused to publish his letter defending himself and his work in the magazine and threatened to sue him if he put their attack on his website along side his reply.
The following is a excerpt frm a lettr to Mr. T. Boone Pickens on his proposal to have the government fund the power and natural gas lines for his proposed wind farms and gas wells.
"Those who oppose drilling for oil also oppose the use and development of coal, shale, dams, nuclear and even wind mill(NIMBY Liberals) as energy sources all of which would be provided by investments by corporations while preferring to place their hopes in investing tens of not hundreds of billions of dollars wrested from taxpayers in the hopes that sometime in the future energy sources will be developed that will not only replace the today's energy sources but will keep up with increasing demand of the future. The ultimate source for this future energy world be it sun, wind, crops or waves is dependent on the fickle whims and fancies of mother nature an often brutal and unforgiving taskmaster. Both Newton and Einstein used a 'thought' idea to set up and think through a problem and there doesn't see to have been much thought given to to possible problems and unintended consequences of an all electric world when hurricanes, tornados, earthquakes, floods, droughts, hail, snow/ice storms or enemy actions wreck havoc on the power transmission systems.
At least today gasoline and diesel powered emergency vehicles, fire, police, power company trucks from all over the US, ambulances and peoples' own vehicles were operational. How will the power companies,governments and individuals cope when such necessary vehicles are dependent on electric power and transmission lines are brought down by weather occurrences, an extended blackout from overloads or possibly an enemy EMP attack?"

John Lockwood| 10.28.09 @ 8:05AM
It isn't just Scientific American either. The other popular-level science level magazines have long since been drifting into ultra-liberal politics, offering their leftist opinion as scientific fact.
Mitch| 10.28.09 @ 8:30AM
I used to subscribe to Discovery and Popular Mechanics, among other magazines, but didn't renew around the turn of the century because they were filled the the same crap as this Scientific American article. Discovery was way over my head with a lot of their magazine, BUT I'm not that stupid.
Jim Wilson| 10.28.09 @ 8:47AM
As a youngster I found science and mathematics within the pages of Scientific American. Several years ago I noticed the drift into the Unscientific American and stopped reading it. I thought I was the only one who was troubled by the decline of a once great publication. I'm relieved to know that I am not alone. Read American Scientist.
Ben Van Johnson| 10.31.09 @ 9:38PM
I subscribed to SA until about 1999. I noticed long before that, though, that something was going amiss with its contents. The articles with equations, diagrams and charts were replaced with pictures, the writing became simplistic, the attacks on Christians (in editorials and articles) via Darwinian evolutionary boosterism and "big-bang God is not necessaryism" became rampant, etc. When Ronald Reagan was president, the mag would constantly trot out a Dr. Kosta Tipsis, to deny that missile defense was, or ever would be, possible. The final straw was an issue with a center-fold of a man who had had himself mutilated via a "sex change" operation, with an accompanying store about the brutality and sexism of the scientific community.
Richard Hilson| 10.28.09 @ 8:47AM
In general, a good article.
I have to point out that Mr Tucker is way off on the diameter of a 5MW windmill. He assumes that the power has a linear relationship. He is incorrect. The fan laws state that everything being equal, the power is a function to the 5 power. So if a 3 MW windmill has a 300 ft diameter, a 5 MW windmill would have a 333 ft dia, everything else being equal, RPM, etc.
William Tucker| 10.28.09 @ 9:04AM
Richard,
Thanks very much. You are correct.
daveng43| 10.28.09 @ 9:36AM
The force of the wind being proportional to wind pressure and the area of the fan blades indicates that the fan laws are irrelevant in the diameter. A differently shaped fan blade (larger area) can produce the same power with a smaller diameter.
Bill Powell| 10.28.09 @ 11:10AM
Dave - don't you think they are probably using the most efficient blade design currently known? I mean, there must be a reason for the currently used design and size.
Ryan| 10.28.09 @ 3:40PM
Not necessarily - models and prototypes and math can only be reasonable predictors, but real-world behaviour can send all the calculations to the wind...as it were. What's practical on paper may not carry out in the field.
JeffT| 10.28.09 @ 8:49AM
Not to mention the fact that environmentalists will NOT allow any of this to be built. Just try getting anything built nowadays, and you'll wait years for the dreaded environmental impact statement to be drawn up. Never gonna happen. We're just SOL.
LtCol| 10.28.09 @ 9:23AM
ALL the popular mag's are in the same boat, and made that change in the late 1990s. National Geo is off the wall...every story this year had to have some comment, however slight, about global warming...I've stopped taking them and they keep sending me letters wanting to know why.
Flee| 10.28.09 @ 3:31PM
Me too. They went off the global warming cliff a few years back and refused to offer any space for differing viewpoints. I think that is what is missing most from this subject is the lack of presentation of alternative viewpoints. If you want to radically alter all of our lives at least have the common courtesy to allow for an alternate opinion.
John II| 10.29.09 @ 1:32AM
Me three. But my wife and I still get National Geo each month, not for the shabby writing and smug propaganda but for the fabulous photography and the intermittent maps. And we store them in the garage as usual, year after year, in the expectation that our grandkids and maybe even their kids will some day find good use for the great pictures in their school projects.
But the reliable techie quality of the mag always puts me in mind of Michael Oakshott's famous characterization of the current era: we live in a time when technical proficiency trumps reason.
KyMouse| 10.29.09 @ 11:36AM
LtCol (thank you for your service), I've noticed for years that National Geographic has had that slant. Many articles give the impression that the world would be a better place if humans died off altogether -- that's especially true in articles about the deforestation of the "rain forest," which I still call "jungle." (I say "swamp" instead of "wetlands," too -- sue me, NatGeo!)
Peter C. | 10.28.09 @ 9:44AM
I unsubscribed to Unscientific American years ago over their constant harping over "global warming". I'm glad to see others are catching on.
Doug Crockett| 10.28.09 @ 12:31PM
I subscribed to Scientific American for almost 30 years, from junior high school until it decomposed about the time Martin Gardiner left (in the late 1980's I think). At that time, a new publisher came on and the content started loading up with liberal political nostrums. I quit when the editor started urging readers to contact a state school system that was trying to evaluate science courses that included non-Darwinian material. I figured that if I wanted to read something like Time magazine, I could do it by reading Time magazine.
chaynes| 10.28.09 @ 9:53AM
Dear Messrs Hilson and Tucker
Very respectfully, your figures on windmill sizes are incorrect. To be correct, the wind speed must somehow increase when you make the windmill bigger.
With a fixed wind speed, available windpower depends on the amount of air flowing through the windmill, much like hydroelectric dams, whose power depends on tthe amount of water, for a fixed height. For that reason, the power depends on the square of the diameter. If a 3 mw windmill is 300 feet in diameter, a 5 mw windmill would be 390 ft in diamter. Big windmills turn slower than small ones, much the way a big boat propeller turns slower than a small one.
On a separate subject, Federally funded scientific research indicates that wind may not blow continuosly, nor the sun shine at night, at least in certain locations. Did Drs. Jacobsen and Delucchi have any figures on how many baterreries would be needed to store the power, in the event that the output of the windmills and solar panels happens to drop off?
Dave| 10.28.09 @ 12:43PM
Chaynes,
Haven't you heard. The used (up) batteries from the Chevy Volt will be used to store solar power. When you have tyo swap out the batteries, the old ones go to the solar plant. LOL
Scott Nelson| 10.29.09 @ 5:38PM
Actually, the most promising energy storage method doesn't ruse batteries. It uses the intermittent power source to pump water uphill to a reservoir and then release it when needed to run a turbine. It's sort of an artificial hydroelectric concept.
JoshInHB| 10.28.09 @ 10:03AM
Last year there was a large solar reflector project, I think around 100mw, that was ready to be built in the mohave desert in ca that was killed by an environmental lawsuit. Everything was ready to go on it, planning was done, financing was in place etc. and the enviros killed it to "save" a tortoise.
JoshInHB| 10.28.09 @ 10:06AM
Actually it was a 500mw project

I stopped taking SciAm years ago as well when it became clear the magazine was firmly rooted to the left wing agenda of the global warming hoax, science be damned.
L. Ross| 10.28.09 @ 10:29AM
I took SciAm for years and years. Had to give it up because they basically dropped the science and just sell liberalism.
On a different point, I like windmills. I live close to Palm Springs, and I think they are simply beautiful. I would have no problems with millions of winmills dotting the landscape. I have always wondered why they don't replace the high tension towers with windmills. They could have electrical generation and transmission co-located.
Appleby| 10.28.09 @ 10:48AM
Our dear leader in Ontario (Canada, not California) has decided to go full speed ahead with windmills despite the fact that people who live as near them as he plans to place them have reported medical problems caused by the low-level continuous noise they make, and environmentalists point out that they are effective bird-and-bee-shredders.
Dear Leader Dalton refers to these complaints as "NIMBYism" and brushes them aside.
Fortunately Ontario is beyond bankrupt and none of this stuff can possibly be built; it's just a feint to try to fulfill a campaign promise to close down all our coal fired plants by 2005, leaving us here in a cold Northern country (Al Gore was wrong, it's not warming up here) to freeze in the dark.
Currently we have a group of hysterical Marching Mommies protesting the idea of running trains from downtown to the airport, plastering signs on their baby strollers shrieking SAVE MY LITTLE LUNGS! Their claim is that the line would be running 400 trains per day, which is impossible because we don't even have 400 trains in the whole system, and if you ran them that close together they'd never be able to stop for passengers.
But logic never stopped a Marching Mommy.
Otis, my man| 10.28.09 @ 8:06PM
I hate the windmills. I think they are a blot on the landscape. They wrecked a perfectly beautiful view of the eastern side of the coastal range near San Francisco. Driving on I-80 through that pass I get nauseous from the spinning blades all along the horizon. The many non-spinning ones look like wilted flowers. What a mess.

A recent Sunday story of Rumpke dump (Cincinnati, OH area main dump) stimulated me to do a bit of approximate arithmetic. Up to 10,000 tons of household trash a day is placed in Mount Rumpke. Assume on the conservative side that 60% of that trash is carbohydrate or carbohydrate equivalent which is 6,000 tons which is 12,000,000 pounds. A pint is pound so there is 12,000,000 pints of carbohydrate equivalent. At 8 pints to the gallon there is 1,500,000 gallons per day of carbohydrate equivalent At 42 gallons to the barrel there are 35,000 barrels per day X 365 days per year means 1.3 million gallons of fuel equivalent placed in the Rumpke dump per year. Note I am neglecting yards and tree waste , construction demolition waste, animal feed lots, and so forth.
This waste, which is collected anyway, should be transported to a nuclear plant. There using the waste heat that is now vented into the air to power the grinders, blowers, electromagnets and other equipment that is necessary to heat and process the waste into useful liquids such as methanol, ethanol and biodiesel. There are a number of pilot plants in the United States that are used to convert wood and other carbohydrate waste into biofuels. We need such pilot plants to be designed to be powered by waste heat from nuclear and cola plants.
Using waste that is now buried to produce fuel is carbon neutral and would significant lessen the amount of petroleum now used.
robert hord| 10.28.09 @ 11:20AM
There is a lubricant available that will lower starting speed of a wind turbine from 7.8 mph to perhaps 2 to 3 mph if used in place of what they now use. Try and get the builders to adopt it now.
Mark Murphy| 10.28.09 @ 11:23AM
I love reading Scientific American. But as a lay person its still fairly easy to spot the garbage. A couple of years ago they had an article proposing a scheme to return the west to the condition it was in before humans arrived. It involved importing large mammals like elephants to replace the mastadons, lions and other critters. They didn't think they could get the government to go for this, just wait a few years, so they suggested that rich people should set up private preserves for this purpose.
I read somewhere that the only real sciences are math and physics and everything else is somebody's opinion.
Mark Murphy
axbucxdu| 10.30.09 @ 1:19PM
Mark Murphy said: "I read somewhere that the only real sciences are math and physics and everything else is somebody's opinion. "
Math isn't a science, heaven forbid, nor can modern physics cannot escape the category of "somebody's opinion"...
Paul from SA| 10.28.09 @ 11:43AM
Scientific American, Discovery, Popular Mechanics, Poplular Science, Nature, Science, National Geographic are magazines I used to subscribe to. Now I will not even read them for free. It got so bad, where you could be reading a fine article and toward the end, it seemed like the author was required to trash Republicans, conservatives and George Bush and blame us for all the worlds problems (all conservatives are corrupt and inferior: Conservatives are against science. Conservatives are against the environment. Conservatives are against economics. Conservatives are against the truth.).
Meanwhile they have no evidence for what they are claiming. Whether its global warming or their hatred for conservatives.
Reader's Digest, Time, Newsweek and so many others were hijacked by leftist anti-conservatives.
I think they make all their money from office subscriptions.
Mark from WI| 10.28.09 @ 11:53AM
After a near 15 year subscription to Scientific American, I cancelled it two years ago for numerous issues matching those expressed in this column. When contacted by phone regarding the reason for my cancellation, I was told by the caller that others were cancelling for the same reason.
tj| 10.28.09 @ 12:08PM

"We the People" can win this if we all take up the mantle against corruption and take back our country. I will never send the GOP any money evuh again until or when they return to conservative values....they just don't get it!!! Duh! What part of you lost the last 2 elections does the GOP NOT UNDERSTAND???
Anneke| 10.28.09 @ 12:23PM
Not only does this say something about the state of the magazine, it also says a lot about the state of science, especially in Academia. Too many scientists have been co-opted by environmentalism and group think. Political, social, and private agendas say "think green" and objectivity goes out the window. I recently watched a biochemistry professor/researcher shed tears over the "grave danger" the planet is in due to climate change. When emotion and self-interest (grant funding) trump rationality, science becomes belief and a religion unto itself.
mujalan| 10.28.09 @ 12:33PM
Anneke, you have said it well. I used to subscribe to SA and eagerly looked forward to getting my hands on any issue I could. The last issue or two I have picked up have been major disappointments. But you are right that all this should be setting off warning bells in our scientific community. Observations of some of the other, populist, "scientific" publications seem to point in the same direction.
Bob Miller| 10.28.09 @ 12:34PM

cdc| 10.28.09 @ 12:41PM
The irony here is hilarious. The National Spectator, a publication that regularly espouses the pseudoscientific gibberish of the Discovery Institute, criticizing Scientific American for being insufficiently rigorous.
I'm all for nit picking SA's articles, exposing errors makes science stronger, but can you direct a modicum of this skepticism at the next Discovery institute press release (I'd say research article but they have never done any).
Big Leo| 10.28.09 @ 3:22PM

cdc| 10.29.09 @ 10:38AM
yes, American spectator. A significant mistake helpfully pointed out by several of the keenly observant readers of my post. my apologies for the inadvertant confusion I might have caused
DBL| 10.28.09 @ 12:59PM
In 1986, Scientific American was sold to a German publisher, Verlasgruppe Georg von Holtzbrinck GmbH. Some time after that, the old management left and the new owner installed new editors and a new publisher. The new crew obviously decided to chase circulation and ad dollars by dumbing down the magazine and pandering to the conventional, liberal biases of the Upper West Side. The result is plain to see.
By the way, Mr. CDC, the name of the magazine you are criticizing is the "American Spectator," not the "National Spectator." Your criticisim of the Discovery Institute is spot on, but irrelevant to what's happened to Scientific American over the years.
DBCooper| 10.30.09 @ 9:12PM
The actual date that SciAm went in the toilet was 1984 when Gerard Piel died and left his brainless son Jonathan as president and editor. Verlasgruppe simply carried on the existing tradition of using editors who were not scientists.
Thank you for encouraging me to research the year that I quit reading the magazine and my 30-year collection of issues went into the trash.
CraigZ| 10.28.09 @ 12:59PM
I actually am a big of solar power. My ideal collector would be in geo-stationary orbit over the Pacific Ocean, beaming its power down to floating collectors, and sent via undersea superconducting cable to the mainland. I despair at our civilization justifying its ongoing suicide. I truly believe that we should double down and invest in our future, especially space technology. X-Prizes and other ways to encourage private space efforts are the solution. Lots of innovation, and NOTHING spent until there is a practical device. Let’s say we give the first enterprise with a 1000 MW orbital power station a check for 200 Billion dollars tax-free. Use the Stimulus. Then sit back and watch. And remember, NOTHING is spent until the power is actually coming down from the sky. This is the twenty-first century. It’s about damn time we acted like it.
Brian Mays| 10.28.09 @ 2:13PM
Jon:
Those 5 MW and 7 MW turbines to which you refer are designed to be offshore turbines. These turbines cannot be placed just anywhere. Nobody has placed a wind turbine in deep water yet. They have to be located fairly close to shore.
So where are we going to place 3.8 million of these turbines?
If we lined the entire coastline of the continental US end to end (including the shores of the Great Lakes) with these turbines packed as tightly as we can get them (spaced three diameters apart), we'd have to stack them in 90 rows of turbines to get them all in. These turbines, row after row, would stretch a distance of 34 miles out to sea!
Obviously, a significant portion of these millions of wind turbines would need to be located on land, and the 5 MW onshore turbine has not been developed yet, as far as I know.
This illustrates just how ridiculous Jacobsen and Delucchi's article is.
Mark Owen| 10.28.09 @ 1:22PM
As a geology grad student in the 1970's, the Scientific American was my Bible for factual science. Sadly I have not read one for many years because they have become a politically correct pseudo-science publication of politics. The same goes for all other "Science" publications that I have subscribed to over the years. Are there any truly scientific journals left out there? I still love factual science from many different fields but can't find an honest publication anymore. Can anyone suggest one?
David Govett | 10.28.09 @ 1:59PM
Years ago, used to read the excellent magazine regularly. Haven't bought a copy since it was politicized by the Left.
A metaphor for America.
weirdone | 10.28.09 @ 2:06PM
At some time I subscribed to most of the magazines listed by other comments. The only one I still get is National Geographic, have for about 45 years, I told my wife that I would not be renewing my subscription as I am tired of the Global Warming lectures every time I open the magazine.
Neo| 10.28.09 @ 2:36PM
Scientific American descended into "vanity" status (i.e. the authors like to see their name in print) decades ago.
Big Leo| 10.28.09 @ 3:26PM
I've been on the same course with magazines mentioned by many here. The magazines I used to get have become tiresome propaganda mouthpieces instead of merely informational. I finally dropped my subscription to the National Geographic which my family has maintained for ninety years because it had ceased to be anything but an AGW journal. Sad.
Nick| 10.28.09 @ 3:44PM
This is what is so great about the internet.
I have found several sites that treat science as something that must be provable and repeatable. And when I find new ones, I stick them in my "science" folder.
Sites like MichealChichton.com, JunkScience.com, and Watts Up With That are great on the global warming hoax, as well as other subjects.
Numbers Watch is a good site for showing how statistics are abused by scientists and the media alike.

This reminds me of a childhood experience that I remember. I was about 11 at the time and it was in the mid 70's.
We had a poster contest for alternative power. Mine was, in retrospect, not so good. I think it was a carefully designed plan to use bicycles to generate electrical power. I lovingly gave it to the teacher who took it politely. I later walked by and found it in the trash. It must have had a significant emotional impact upon me since I remember it.
Looking back, it was tough love. It taught me that many of my ideas were crocks and that just because they were noble, didn't entitle them to display even in an elementary school alternative power exhibit.
I suppose the other kids are all victims of their own far fledged balderdash schemes never getting the proper criticism they deserved. They included, as I remember, solar panel generators and windmills...
Otis. my man| 10.28.09 @ 8:15PM
The authors Jacobsen and Delucchi are what unemployed grad students morph into when you throw Federal Grant money at them.
The money gives them the freedom to cook up these crock ideas you refer to while sitting around campus somewhere smoking a bong.
Marc Jeric| 10.28.09 @ 4:17PM
Here is another proud "denier" - one of the over 31,000 independent professionals and scientists (including over 9,000 with PhD's, including me) who signed the "Global Warming Petition" (see Internet) stating that there is no anthropogenic global warming.
This windmill talk reminded me of a visit to La Castilla Vieja in Spain - with those ancient windmills still pumping water from undergroung wells, and remining one of Don Quijote's exploits.

Let's assume we magically come to get all of our energy requirements from wind, solar, geothermal and other so-called 'sustainable' sources, and that the total energy employed is the same as it is now.
Why should I suppose that this moving-around of energy would have total physical and chemical consequences of lesser magnitude than the ones caused by the way we currently move this much energy around? I can easily imagine the effects being different, but it seems to me that the magnitude must be exactly the same.
Not so?

great article explaining the absurdity of sole investment in Renewables. Also great points about nuclear. Where did you get your information?

Stanford University should be embarrassed to allow such a study to even be published. This a bunch of folks that need to get a strong dose of reality – just ain’t possible in the world we live in. The renewables may be out there, but the lack of political will and economics won’t let it happen. Did these characters just figure out that fossil fuels are inefficient? Most people I’ve run into over the last 50 years seemed to already know that. You also have to wonder if they know anything about arithmetic. They propose 3.8 million large wind turbines by 2030. That means we have to build, erect, and integrate into the power networks 520 wind units a day – yes each day! The plan also requires 490,000 tidal turbines (67 per day); 5,350 geothermal plants (about 3 every 4 days); 720,000 wave converters (almost 100 every day); and 1.7 billion rooftop photovoltaic systems (almost 233,000 every day) –Huh!!!!!!!!) Who are these so-called professors. It's scary to think that they're teaching people about energy, a subject about which they obviously have little understanding and to whcih they bring no common sense.

The magazine Scientific American wwass sold to a German publisher mor than a decade ago. The tone of the magazine changed to Social Democrat and has never improved.

Anything but nuke; anything but market; anything but 'natural;' pulleeeeezzzzze! U-235 is natural - and so is the fission process (thank you, Lord.) Delusion is not remedied by an academic credential. The anti-nuke stance is a child of the anti-war 60s and 70s crowd.

Have read copies of "Scientific American" from 60-70+ years ago and the recent editions are pale, in comparison. Hard to imagine that a magazine that wrote about the Wright brothers, Edison, Tesla, and so many others has reduced itself to birdcage flooring.

American Scientist is a magazine comparable in level to the old Scientific American. It is published by a technical society, but is available at bookstores and by subscription.
I have not read it regularly enough to know how steeped in the global warming tea it is, but it is worth a good look.
Joseph Hertzlinger | 10.28.09 @ 8:48PM
Leftist propaganda in Scientific American is nothing new. Doesn't anybody here recall their hatchet job on Herman Kahn?
On the other hand, it used to be segregated in just a few articles. You could ignore the first article, "Science and the Citizen", and the book reviews and the rest would be a safe zone. That is no longer the case.
Raoul Ortega| 10.28.09 @ 10:41PM
Exactly. I started subscribing in high school, and even I noticed back in the 70s/early 80s that the first article was always something that would fit right in with the agitprop in "The Bulletin of the Atomic Scientists" when it wasn't some sort of social science drivel. But it was when they stopped having the covers with the single illustration with a large white border that things went downhill.

Scientific American is now like something out of the movie " Idiocracy ". I used to subscribe twenty years ago. I picked one up at a newsstand earlier this year and saw that things had changed. Lots of big, brightly colored pictures covered the pages with far simpler explanations than I was used to seeing. The article titles were sensationalistic and the articles themselves short on , well, science. Ugh.
I want to say something about windmills as well. We've got a lot of them near my town, and most of the time at the biggest nearby farm, most of them aren't turning. I don't think this is due to maintenance. I talked to a guy who recently retired from Penelec and got the sense that many of them are only activated when demand goes up because wind energy is unreliable in terms of providing base power generation. This probably means the authors underestimated the number of windmills we'd be needing.

The dirty little secrect the fanboys don't like to talk about is embodied energy (the total amount of energy required to build a working windmill). Rarely will the device return the embodied energy investment in less than 10 years (about the standard lifespan of a windmill turbine).
God put oil, gas, coal and uranium in the ground becuase he loves us. We should be gracious and accept the gift responsibly.
Windmills are an eyesore.

I took the magazine for years, starting in 1970, and loved it. Then they started with the PC articles and I dropped them like a hot potato. I refuse to give my money to a PC company. They will go the way of the newspapers. How's that liberalism working for your balance sheet now SA?
JohnWesternMass| 10.29.09 @ 3:33AM
I've not seen anyone mention biomass as an alternative to fossil fuels for generation electricity. Several writers have noted that wind and solar can only provide "peak" power (when the wind is blowing and/or the sun is shining). Biomass and hydro are the only two major renewables capable of providing "baseload power" (a constant flow of electritiy 24/7).
Environmentalists claim that biomass will denude our public and private forests but the fact is that every state creates what is called clean waste wood in the form of roadside clearing debris, old broken wood pallets, stump removal, and the "slash" created by commercial logging operations which leaves 40% of the tree on the forest floor. NIMBYs are theoretically correct in their fears of laying waste to our forestlands but only if too many biomass plants would be built.
Futher, market conditions would mitigate against clear cutting forestlands. Here in Massachusetts, more forestland is owned by private parties than by the state. No forestland owner in his right mind would sell a tree worth plus or minus $1,000 as a saw log for as little as $25 a ton as wood chips. And no investor is going to risk his investment unless it is clearly demonstrated that there is a sustainable wood fuel supply.
Unlike a lot of other readers of the American Spectator, I don't think that global warming is a hoax. I think we're in deep doo doo, primarily because an ever-expanding global population places strains on the environment in many ways including the need for more electric power and the consequences of that need.
Nick| 10.29.09 @ 11:42AM
John,
Instead of THINKING that "we're in deep doo doo", is it not better to base your conclusions on facts?
Go to MichaelCrichton.com and read his speeches on AGW.
Jim O'Brien| 10.29.09 @ 7:37AM
Ask the average American if "greenhouse gases" are bad, and he will say Yes. The public doesn't even know that the earth would be much too cold for humans if we did not have greenhouse gases. The public doesn't even know that water vapor is a major "greenhouse gas". The public doesn't know that CO2 is essential for life, doesn't realize that CO2 is merely a trace element in the atmosphere (about 380 ppm), and doesn't understand that climate is so complex that even our best scientists don't understand it. The weatherman can't tell us for sure if Hurricane K will hit Florida or Louisiana in 48 hours, but the "climate scientists" of academia claim to know that the average sea level in NYC in 2075 will be 13 inches higher than now. Boy, are they smart or what?
I notice in my local public library that there are about 20 rows of novels, but just two rows of science and math books ...........

Why is there so little discussion about the energy savings that can be achieved with conversion to L .E.D lighting ? Not only the energy, but the ongoing maintenance, initial installation [ less copper all the way back to the power source! ] Another considerable benefit could be the flexibility of directing the light to what you intend to illuminate [ not outer space or your eyes ]. If you do the math, even retro-fitting with still costly bulbs compelling.
JOHN ROLIN| 10.29.09 @ 5:00PM
When I was in high school and college, I used to love the Science and Mathematics in SA. Now that I am retired, I find that the magazine has devolved into a social -cultural screed for the liberals. It is not only the magazine, but this unfortunate state of affairs in many scientific endeavors today. Just look into what is happening in the GW debate.
It is a sad day when scientists pervert science in the service of polical and social causes.
Blane Burns| 10.30.09 @ 3:45PM
The basis of all serious breackthroughs in science are the result of philosophy. Wild hair (Hare?) ideas and flights of fantasy. That is how Einstein and company did it. Talking math and 'what if's'. The problem now is tht we have small minds with too much education and too narrow an education. People educated beyond their intelligence. We meet them every day. They are blinded by their own diplomas. They get where they are by telling folks what they want to hear. Science has been that way for years.

With the possible exception of the chief Skeptic himself, Michael Shermer, genuine skepticism appears to be as scarce at Scientific American as evolution is in Kansas’ public schools. Even Michael, when it comes to economics and the impact of science on our economic systems, appears to be a SINO (Skeptic In Name Only). As a longtime subscriber and fan of the men and women working to advance our understanding of the universe around us, I have seen a noticeable trend in support of left-of-center-only (LOCO) opinion related to climate change, economics, healthcare, and other issues. My perception may be incorrect but it seems the direction of editorial opinion, for example, in perspective and sustainable developments is clearly tilted in a direction supported less by facts than ideology. Mr. Tucker’s point is also well taken that “A Plan for a Sustainable Future….” appears long on wishful thinking and short on real world applicability.

I've been reading Scientific American for 30 years and I, too, am dismayed by its recent leftward drift. There are far too many articles on "climate change" and the superiority of liberal thinking. The magazine has adopted the same snotty, condescending tone as most of the other magazines that cater to liberal elites. Very sad.

Are there any windmill manufacturers that rely only on wind and solar power to build their windmills? Are there any solar panel makers that rely solely on wind and solar to build their solar panels? I doubt it. If climate change can cause temperatures to go up (see Gore, Al) or down (see "The Day After Tomorrow"), can cause floods and also droughts, etc, etc, how will we be able to tell that we've finally solved the diabolical problem of AGW? I am a real scientist (Ph.D. in organic chemistry) and I am truly ashamed at the state of science today. The first casuality of progressivism is always the truth. Human caused global warming is to science today what bloodletting was to medicine centuries ago. AGW is nothing more than an elaborate hoax funded by generous taxpayer subsidies and its real purpose is as a rationale for raising taxes and bringing about world governance. Even if it is all a lie. For progressives, the end always justifies the means. As for SI, I haven't read it in years, and it used to be my favorite magazine. Rationality will return someday. But that day will have to wait until liberals are out of political power.

"U of Mass. Biologist Jeffrey Dukes calculated that the fossil fuels we presently burn in one year were produced from stores of organic matter "containing 44Å~10 to the 18 grams of carbon, which is more than 400 times the net primary productivity of the planet's current biota." In plain and simple English, this means that every year we use four centuries' worth of planetary plant and animal matter that were converted into fossil fuel over many millions of years. Every single barrel of oil replaces 25,000 man hours of human labor energy. The idea that we can simply replace fossil fuel and the extraordinary power density it provides with a fast market shift to “green” energy is the stuff of wild science fiction. "
