Solar Furnace

Here is something I have an interest in. The French have one somewhere in the south. The mirrors produce heat a million degrees or so. Molten salt is pumped through the tower and the super heat transferred to tanks which can produce steam which will drive turbines even when the sun goes in.

I'm going to make one "sans" the molten salt as you can't get molten salt pumps on Ebay.
