Building a Large Solar Cooker

I started building this unit as a heater for making ice from ammonia, but it bakes cakes and other foods quite well. The metal shell is the shell from the inside of a freezer / refrigerator. You CAN build this too, on a larger or smaller scale. http://www.solarcookomh.org is a good place to go. These photos are the documentation of my construction and baking process. The first item baked was the single cake pictured. A few days later I baked 5 loaves of bread and two cakes in about 1.5 hours. I could of baked about 20 loaves of bread in the same amount of time. There is plenty of rooom in the cooker. I estimate I could of cooked between 4 and 5 batches of 20 loaves in one day in this cooker. The whole thing cost me $9.00 US to make plus the cost of the mylar sheeting which is 11 cents a square foot. I could of used aluminum foil in its place. I bought paint ($4) and clamps ($5) at Home Depot. The glass, the metal 'tub' from a freezer, the sliding glass door for the top, the insulation, the card board was all free or scrap.
