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.
It uses a ton of material to power 73 homes annually (652 feet high and 45 feet in diameter), works best in a desert but requires a lot of water. Yeah, nuclear energy is really threatened by that. Modern microreactors in development make, for example, 1.5 MWe at let's say 90% capacity factor. Assuming about 1000 kWh/mo for a house, that microreactor, which can fit on the back of a semi truck and be transported down the highway that way, can power 985 homes anually and doesn't require cooling water (will require water for electrical steam generation).
There are technology (reactor) demonstrations planned within the next 2-3 years, so not quite but very close. A lot of active R&D work going on right now for specific designs at a lot of companies.
The technologies on which these reactor designs are based have been demonstrated previously. The specific designs are in progress and well on their way. AGR, EBR-II, and MSRE are examples.
Maybe, but I've had plenty of conversations where I've bought evidence, facts, used reliable sources, etc. and I see the same people still lying their asses off.
