Solar Cookers Technology

A new solar cooker that can even cook dinner - looks like an improvement on the technology, but still is not as convenient as other cooking methods that take less time. I thought I did a post on solar cooking earlier. What I found was the only place that Solar Cooking has taken off is in Tibet (fuel is expensive, and can be used for fertilizer) and Darfur refugee camps (this way people don't need to go foraging for fuel, which is dangerous).
