A Helpful Bunch

Popular Science looks at Thiago Olson's fusion reactor.

How did he do it? Olson pored over graduate-level physics textbooks, studied vacuum-pump manufacturers’ manuals, and scoured the Web for cheap parts. Though mostly self-taught, he occasionally solicited advice on a fusion Web site. Once, he posted photos of a cheap photomultiplier tube he’d bought online because he had no idea how to rig it up. Another fusioneer on the site who had the same model promptly told him which wires went where. Amateur nuclear engineers are, it seems, a helpful bunch.

Yes we are.

BTW there is a short video of the reactor in operation at the Popular Science site. Or if you prefer you can go directly to Youtube.
