Of all the ways to heat metal to melting points in order to work with it, using the sun's heat is not usually listed among them. But Green Power Science does just that with this DIY solar foundry. Metal-working, in the backyard, without an open flame. Crazy!
But also still fairly dangerous. Just read the description on the project: "The solar tracker keeps our target illuminated for 8 hours a day enabling build temperatures exceeding 2100˚ Celsius, a new personal record."
Watch some of the metal working that is possible with this solar concentrator:
