I am only a cat veterinarian but I thought up a potentially feasible power generator. Use a fresnel lens or parabolic reflector to focus heat on the junction of two dissimilar metals, creating electricity via the Seebeck effect. There is a power company in the Mojave, it turns out, that does this with parabolics and provides power to 260,000 homes. Can a smarter person than me rig this up and test??(posted 9275 days ago)
