This is a novel idea. Heat up sand during the daytime with solar energy. After sunset circulate the hot sand through a steam generator to run a turbine and generator. Short 2 min video. https://youtu.be/KozXB04eM-c

2021-04-01 “We Need Base Load Generation” Myth

Rep. Rodney Davis (R – Illinois) said, (quoted from interview with Judy Woodruff on PBS Newshour, 2021 April 1, at about 22:00 point) “The problem is, we still have to have base load generating capacity. That means nuclear facilities that actually have zero emission just like the one in Clinton, Illinois. We also make sure

2021-03-22 LCOE Levelized Cost Of Energy – NREL

From FB reply Nuclear power plants are too expensive and are being taken out of service and decommissioned. The San Onofre Nuclear Generating Station is being decommissioned at a cost of 4.4 billion dollars and will take 20 years. LCOE levelized cost of energy is how a utility judges its generating assets. Nuclear and conventional
