If you want to improve the output of solar energy systems, why not also run them at night? That's the question researchers in Qatar and Jordan addressed as they successfully devised a system that promises to more than double energy output of current solar power stations.
Maybe those are the ones running the astroturfing campaigns?
Good call. Who are they shilling for though?
More or less directly for the nuclear lobby I would assume. Or did I somehow misinterpret your question?
