Scientists skeptical of Lockheed Martin's truck-sized fusion reactor breakthrough boast


Re: To the skeptics...

The main problem is the startling lack of detail they provide - however that diagram has one major flaw. The end of the 'bottle' are, as far as I can see, magnetic mirrors. They suffer from the fact that high energy partiicles escape from them cooling the overall plasma and drasticallyt reducing the temperature. As a technology it was obsolete thirty years ago. The neutral beam injetors, well they are quite inefficient and I'm not sure how far it takes to stop the beam (depends on the density of the plasma - again not stated) but that superficially looks too short.

Thermonucear fusion is hard to do, but the required parameters have been around for a *long* time. A Tokomak at least as big as DEMO. It takes time and money and in the 1990s petrol was too cheap and that killed the last big international attempt (particularly the Americans - they did their best to kill it off).
