Current proposals for nuclear fusion, most notably hydrogen fusion variants (ie deuterium-tritium in particular), increasingly seem like a pipe dream to me. Fusion seems attractive because stars do it but stars also have gravity on their side. We hafve to build lmeter thick concrete walls to protect against errant neutrons (as mentioned in the article) but that doesn't solve the real problem: escaping neutrons are energy lost. You also can't ignore the fact that those neutrons also destroy the precise equipement designed to contain the reaction. Add to this, you need to perfectly contain an ultra-high temperature plasma and you run into fairly fundamental issues with fluid dynamics (ie turbulence). I'm disappointed but not the least bit surprised that the pro-fission HN crowd tries to hijack this thread into a fission energy argument. Is it possible to discuss nuclear fusion without bringing the quite unrelated fission issue into it?
