That looks like an awesome idea.
A very hot solution to solar power when the sun goes down!
Molten salt (such as the kind that can be found near Mount Doom), is simply a good conductor of heat. A new power plant will use nearly 20,000 heliostats—basically very focused mirrors—aimed at a focal point in a tower, which will heat up salt to a steamy 1,050 degrees Fahrenheit. Pump that salt near some water and you get enough steam to run a turbine. Hold that salt at that high temperature and then put it near water later and (BAM!) you get power when the sun isn’t out!
