all told, i spent about $30, and half of that was for a digital thermometer that ultimately didn't work for this application. I used recycled cardboard, black duct-tape, home-made wheat paste, and aluminum foil, and recycled newspaper. I got the plans from the solarcooking.org site for a box cooker, and modified them slightly. The rest of the money was spent on plexi-glass. My mum wants one now, and I think I'm going to try to use recycled glass, as well. It will be slightly heavier and more fragile, but I think I'll get better results.

The sad part of the solar cook stoves is that there has been many accounts of cultural differences getting in the way of their acceptance. Some cultures insist that cooking be performed indoors in many cases this is with 3 stone fires and poor ventilation. The absurdity is dumbfounding though so are many cultural tendancies of people in developed countries.
