Sand (or similar things to sand) to store heat. Interesting. They did point out that sand is in short supply, so sand like materials will be needed instead.
I didn't see anything on how they were converting that stored heat into useful amounts of electricity, but I imagine they have their ways. I got a lot of sand around my house... Water table is about 8 feet down.
