On Solar Cooker
29th Mar Finished a rudimentary solar cooker. It got cloudy. Will try it later. The center of the cooker was hotter than surroundings. Stuck some aluminum pouches (will serve as reflectors) on a carton using wood twigs. Covered the inner layer with a black cloth (will absorb heat). Added some insulation (will retain heat) . Covered the carton with a transparent plastic (for greenhouse effect). Hopefully it should work. 30th March The solar cooker is working. It has heated the water pretty good. I am happy. I have added potatoes to check its capability. I had also left a water filled cup out in the open to benchmark it. That cup has not worked even a little. 31st March Adjusted the angles. The water got hot very fast. The cooker's efficiency has increased significantly compared to yesterday. Water id evaporating and condensing.
