The Fusioneers, who build nuclear reactors in their back yards
These are Farnswoth Fusors[1], first developed by Philo T Farnsworth, one of the inventors of television.<p>The devices use about 100,000x more energy than they produce FROM FUSION (edit, thanks), but some fusion does occur. An individual ion can be heated by 11,000 kelvins with a single electron volt, so 15,000ev is enough to reach fusion temperature. The statistical challenge is getting ions to collide - overcome the (repelling) coulomb force - and fuse.<p>There are discusson groups online for this topic [2] and there's even a high school in the Seattle area that has a fusor [3].<p>[1] <a href="https://en.wikipedia.org/wiki/Fusor" rel="nofollow">https://en.wikipedia.org/wiki/Fusor</a><p>[2] <a href="http://www.fusor.net/board/" rel="nofollow">http://www.fusor.net/board/</a><p>[3] <a href="http://www.industrytap.com/overview-polywell/31940" rel="nofollow">http://www.industrytap.com/overview-polywell/31940</a>
