Solar Thermal Coffee

Ok so we're no baristas, we're popcornistas. But coffee beans turn out to be perfectly suited for solar thermal cooking. The same kettles used to make popcorn can be used to roast coffee. There are some limitations. It's sort of impossible to observe them as they roast, and smelling them is quite difficult. But we found we could make a tasty medium roast nontheless. It might not be coming down the BjornQorn pike any time soon, but we'll keep investigating.  Beer next?
