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!

Molten Salt and Rocket Science To Make Solar Energy Work At Night

This video accompanies one of our April feature stories about Transforming Sustainable Energy in Afghanistan. It really makes you think about how living, literally off the grid for so long can be turned into an opportunity to bypass the step we are all trying to make now (in transforming our wasteful daily ways) and go straight to sustainable living and using renewable energy sources. Kudos to the team for putting this together!

There’s more where this came from.
