Successful second round of fusion experiments with Wendelstein 7-X
I thought the main problem with nuclear fusion is neutron capture converting the structural materials which are no longer fit for purpose.<p>I'm quite keen on aneutronic fusion, Boron 11 + a neutron, which converts to three alpha particles which can lose their energy to magnetic fields generating electricity, no need for any Victorian steam engines.<p>The huge downside is that works at much much higher temperatures, but if you can't solve the neutron capture issue...
