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.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.The huge downside is that works at much much higher temperatures, but if you can't solve the neutron capture issue...
