Solar power plants have one problem: they can’t make power at night! Until now. Use inexpensive mirrors to focus the sun’s heat on a single tower full of salt. Then pump the liquid hot salt to a water boiler to create steam that turns a turbine that turns a 500 Megawatt generator. Who would have thought salt was the best way to store heat? They will probably find something even better in a few years. For now, we have something that is basically free and non-explosive and non-toxic so that’s good.
