> What about the big fusion reactor in the Sky? Shouldn't we go all in on solar? Perhaps we should not go "all on" anything. Solar is available now, it's getting cheaper by the day, and it's very easy to install and use. But it's intermittent, requires storage, it's not portable except at low levels, and energy density is not that great. Fusion is obviously not available now. But when figured out, it would have all the strengths of classic nuclear energy without most of its weaknesses. We should keep deploying solar as fast as possible, while aggressively pushing for fusion research.
