I’ve volunteered to build a small experimental solar furnace for my housemate, which he’s been hankering to make for a while now but has gotten low on his priority list. Since I think this stuff is pretty cool, I like power tools (woo-hoo!), and I’m not teaching this summer, I figured, “Why not?”
Here’s the link to make it by the way: http://www.amasci.com/amateur/mirror.html
It’s all done with mirrors… lots and lots of little one inch mirrors, all reflecting sunlight on one very bright, very hot focal point. Think of a satellite dish and radio waves, and just coat that dish with mirrors and substite photons for radio waves. Woo-hoo!
Let’s go and heat up some tea!
