Lockheed says makes breakthrough on fusion energy project
"Lockheed Martin Corp said on Wednesday it had made a
technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade. Tom McGuire, who heads the project, said he and a small team had been working on fusion energy at Lockheed's secretive Skunk Works for about four years, but were now going public to find potential partners in industry and government for their work. Initial work demonstrated the feasibility of building a 100-megawatt reactor measuring seven feet by 10 feet, which could fit on the back of a large truck, and is about 10 times smaller than current reactors, McGuire told reporters."

They hate that. - Anonymous these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

Lockheed says makes breakthrough on fusion energy project
/quote
Lockheed shares fell 0.6 percent to $175.02 amid a broad market selloff. /end-quote Or how about N times the cost for 1/Nth the smell? I smell skunk alright... When it comes to fusion "announcements" such as this I'm about as grumpy an old man as you can get. Having USENET chops that date back to the Pons & Fleischmann debacle.... So what they've announced, apparently, is some kind of 'technique' for a fusion reactor that makes it much smaller than any proposed to date. Left out of the article: 1) Is proposed reactor capable of going beyond breakeven? Well unclear. We have these quotes from the article: /quote In a statement, the company, the Pentagon's largest supplier, said it would build and test a compact fusion reactor in less than a year, and build a prototype in five years. /end-quote Well heck, a college kid just a few years back built a Farnsworth fusor in his physics lab. Sucker works fine. As have Farnworth fusors that have been built since the 60's. Do they generate power? No. [2] Just exactly what are the performance specs for the 5 year prototype? More info less hype please.... 2) How do you deal with the copious amounts of neutrons produced in D-D fusion? And how is the shielding prevented from become lethally radioactive eventually? 3) Seen this befo /quote Ultra-dense deuterium, an isotope of hydrogen, is found in the earth's oceans, and tritium is made from natural lithium deposits. It said future reactors could use a different fuel and eliminate radioactive waste completely. /end-quote. Ah yes, the aneutronic "advanced" fusion fuels such as 3He-3He, p-11B and p-6Li. I refer Mr. McGuire to an MIT PhD Thesis by Dr. Todd Rider[1], published in 1995, who killed off his own pet project! I quote the following: /quote For the record, the author would like to apologize for apparently killing some of the most attractive types of fusion reactors which have been proposed. He advises future graduate students working on their theses to avoid accidentally demolishing the area of research in which they plan to work after graduation. /end-quote and furthermo /quote Analytical Fokker-Planck calculations are used to determine accurately the minimum recirculating power that must be extracted from undesirable regions of the plasma's phase space and re-injected into the proper regions of the phase space in order to counteract the effects of collisional scattering events and keep the plasma out of equilibrium. In virtually all cases, this minimum recirculating power is substantially larger than the fusion power, so barring the discovery of methods for recirculating the power at exceedingly high efficiencies, reactors employing plasmas not in thermodynamic equilibrium will not be able to produce net power. Consequently, the advanced aneutronic fuels cannot generate net power in any foreseeable reactor operating in either in or out of equilibrium. Moreover, D-3He can only produce net power when burned in thermodynamic equilibrium, which means that in any possible D-3He reactor, the neutrons and tritium produced by D-D side reactions cannot be reduced below a certain level, which is calculated. /end-quote So maybe McGuire & Co. have beat the odds by upping the efficiency ante via PowerPoint? Or maybe they have Dr. Rider on staff? [1] http://dspace.mit.edu/handle/1721.1/11412 [2] http://carlwillis.wordpress.com/2008...usor-carls-jr/ |

.... And why is it these guys *always* need partners to see it through? Just build the damn thing! You'll have no problem selling them if they work!

Suggesting the market believes that Lockheed is throwing money down the drain? I have to wonder at the ten times smaller claim. Given that there are no functioning fusion power generators, ten times smaller than what? Ten times smaller than other reactors that don't produce a net power output? It's not clear what they're claiming they could build in a year, but if it's a proof of concept reactor, I'll just wait for that before opening my wallet. Sylvia. |
