"World's Biggest Science Experiment"

As I was saying:  Fusion falters under soaring costs.

Some scientists also believe that the technical hurdles to fusion have become more difficult to overcome and that the development of fusion as a commercial power source is still at least 100 years away.

At a meeting in Japan on Wednesday, members of the governing Iter council will review the plans and may agree to scale back the project.

"This is a vast global project to show the scientific feasibility of fusion as a limitless source of energy. "On top of this platform we are going to build 130 buildings. The main building will contain the Iter machine itself. "It will be huge - the size of the Arc de Triomphe in Paris - and it'll weigh about the same as a battleship - 36,000 tonnes of metal and instrumentation."


What's the old saying, 'fusion is 100 years in the future and always will be"? Sounds to me like they're going to need an infinite source of energy just to build the damn thing.

IEEE Spectrum: Fusion on a Budget

This article originally appeared in the IEEE Spectrum back in March, 2009, but is only now available online:

RH-FoaB .... it’s pretty simple, according to Paul Schatzkin, who runs Fusor.net, a Web site where amateur ”fusioneers” congregate to swap equipment and advice: ”Find two stainless steel half-spheres, seal them together around a wire grid, suck the air out of it, apply some high voltage to the grid, inject a bit of deuterium into the chamber, and sit back and count the neutrons.” Don’t expect to reach energy breakeven, Schatzkin says, but at least you’ll be failing to achieve practical fusion at only a millionth the cost of a tokamak....

Building a fusor is simple enough for amateurs to contemplate because of the enormous global inventory of used lab equipment, says veteran fusioneer Richard Hull. For example, fusion containers need only achieve pressures of about one millitorr; vacuum pumps with that capability make their way to eBay for US $10 to $100. High-voltage feedthroughs are in the same range—or free, if you build your own from microwave-oven salvage. The most expensive items, according to Schatzkin, are neutron detectors, which have to be purchased new. But a cheap workaround is available, Hull says: You can prove your fusor is working by irradiating a piece of silver and watching the decay of the Ag-108 and Ag-110 isotopes with a simple Geiger counter.


Yes, ITER and NIF may be getting all the press (I still haven't heard from NYT's Friedman...), but the real action is taking place in basements and garages.  Follow those two links and look at those two facilities.  They can't be serious.

Cold "Fusion" is "hot" again??

Maybe the worst thing that ever happened in the annals of fusion research was the announcement of the discovery of "cold fusion" back in 1989. Now, whenever I mention the subject to somebody, invariably the answer is "oh, you mean 'cold fusion'?  Well, no, that's NOT what I mean. 

Now CBS has breathed new life into the concept with a segment on 60 minutes:

NYTimes Thomas Friedman Discovers Fusion

NIF_fig10_role Unfortunately, he discovered it at the National Ignition Facility, where they can spend tens of millions of dollars on a single burst of fusion produced by a finely-tune array of nearly 200 laser beams:

Hang around long enough and you’ll even hear that in another 10 or 20 years hydrogen-powered cars or fusion energy will be a commercial reality. If I had a dime for every time I’ve heard one of those stories, I could buy my own space shuttle. No wonder cynics often say that viable fusion energy or hydrogen-powered cars are “20 years away and always will be.”

But what if this time is different? What if a laser-powered fusion energy power plant that would have all the reliability of coal, without the carbon dioxide, all the cleanliness of wind and solar, without having to worry about the sun not shining or the wind not blowing, and all the scale of nuclear, without all the waste, was indeed just 10 years away or less? That would be a holy cow game-changer.


Tom, do you want a REALLY "holy cow game-changer"?  Then how about a process that produces real, hot, "thermonuclear" fusion in a device you can build in your own basement or garage?  Instead of a facility the size of an auto factory, costing tens of millions -- if not hundreds, or billions -- of dollars, suppose fusion could be achieved in a device that costs about as much as a good set of used golf clubs?

It's possible, and in fact it's being done almost every day in a device first demonstrated more than 40 years ago by electronic video pioneer Philo T. Farnsworth -- as described in my book, The Boy Who Invented Television.

Admittedly, the process we're talking about here -- the Farnsworth fusor -- produces no more "energy gain" (we call it "break-even," Tom) than that behemoth in California that you found so impressive and promising. 

But if it's a real "paradigm shift" you want in the way the world produces energy -- clean, (relatively) safe and virtually unlimited energy -- then what could be more promising than a machine that occupies about as much space as a microwave oven? 

And what could be more exciting than a process that is being effectively explored on a grassroots level by dozens of people around the world who are producing fusion in their own basements and garages -- and then comparing their results and sharing data with their colleagues around the world via the Internet?

Now, there's a really interesting prospect:  instead of holding out for a future where energy production continues to be controlled by large and well-capitalized industrial interests, suppose we could all produce more clean energy than we could ever possibly use.  And do it right in our own basements from a benign fusion energy device -- a gadget that would occupy the same space our oil, gas, or coal burning furnace occupies now? 

That was the vision articulated by Philo T. Farnsworth when he first developed the Fusor in the 1960s.  And while anybody building a Fusor today will tell you that they are many orders of magnitude from anything approaching "break even" or net energy production, the effort is worth noting, because dollar for dollar, the Farnsworth approach is producing vastly more amounts of actual fusion than the immensely complicated devices like you toured at the National Ignition Facility.

In your op-ed piece, Friedman concludes:

...we need to make a few big bets on potential game-changers. I am talking about systems that could give us abundant, clean, reliable electrons and drive massive innovation in big lasers, materials science, nuclear physics and chemistry that would benefit, energize and renew many U.S. industries.


And I agree, we need to make a few big bets.  But we also need to make a few SMALL bets, and stop looking toward gigantic institutions to deliver the solutions we need if they can perhaps be delivered instead on an entirely different scale.

Speaking of "Change..."

Stemcell I'm still getting static (in the form of snarky comments) to that "Nobel Laureates Endorse Obama" post from a couple of months ago, so I'm leery of making "political" posts in this this space.  But this isn't politics, it's just "news."  (And rather old news at that, the dateline is like 10 days ago....)

WASHINGTON (AFP) – President-elect Barack Obama on Saturday signaled climate change and genetic research will be among his top priorities when he takes office as he named White House science and technology advisers.

"Today, more than ever before, science holds the key to our survival as a planet and our security and prosperity as a nation," Obama said in a weekly radio and video address.

"It's time we once again put science at the top of our agenda and worked to restore America's place as the world leader in science and technology."

Obama's comments were a clear reference to President George W. Bush's administration which has been accused of downplaying scientific findings on climate change and genetic research.


Now, before anybody gets riled up and posts a comment about the new president's middle name or the former domestic terrorists in his neighborhood, kindly recall this statement, attributed to John Wayne in the wake of the 1961 inauguration of John F. Kennedy:

"I didn't vote for him, but he's my President, and I hope he does a good job."


Which is really all anybody can ask for at this juncture.

"Flash of Genius" - A Timely Reminder

The release of the new movie "Flash of Genius" has brought the subject of  How Inventors Always Get Screwed into the daily media diet.

Armstrongtm BTW, if you don't know about Armstrong, you should read Lawrence Lessing's (he's not the Internet Lessig) 1956 biography, "Man of High Fidelity." The book is sadly out of print (old paperback copies are selling for $25.00 on Amazon (NSDQ: AMZN)). ortunately, though, the complete text of the book has been posted here by the Internet Archive...

Anyway, if you think American technological prowess begins and ends with the Mac and iPhone, you owe it to yourself to read this tale of a true genius struggling against those out to steal the fruits of his brilliance. In Armstrong's case, his nemesis was RCA impresario David Sarnoff....

RCA -- along with Westinghouse and a host of other companies -- infringed Amstrong's patents for years. He was less lucky than Kearns, though. He committed suicide by walking out of a hotel window in 1954...

The point I want to make is that people who think modern technology sprung fully realized in some easy and fun way from the landscaped corporate vistas of Silicon Valley don't know squat. Every development from Maxwell, Edison, and Tesla; up through Marconi and De Forest; to Eckert, Mauchly and the present day has not come without a humongous struggle. (For another great tale of inventor screwing -- tellingly, also involving RCA -- read Tube: The Invention of Television by David Fisher, about the travails of Philo Farnsworth.)

 

The importance of this topic in the current scenario cannot be over-stated.  Our leaders keep telling us that we're going to innovate our way out of the current energy / economic / environmental crises.  Maybe somebody needs to remind our leaders what really happens to the individuals who produce the innovations we're counting on to reshape the world.

If they really want to "transform America" (as one of the major party candidates stated upon launching his campaign), then they need to take a long hard look at how individual genius suffers in a world dominated by monolithic corporate capitalism.
