Also frankly that a nuclear reactor isn't simple - neither is a coal power plant really. Serious, large engineering is always complicated: argument from incredulity is a fallacy for a reason. Solar panels are cheap because the supply line of ultra-pure silicon is incredibly well-developed to service the computing industry (it basically runs on discards from it). You have to do the actual engineering before you'll know whether or not a thing is viable, and you're likely to find some surprises - i.e. a lot of advanced capability these days has become possible due to things like cheap, fast computing power or ubiquitous high-accuracy GPS systems (differential GPS can get ridiculously accurate).
