A mixture of clay, cow dung, mustard oil cake, and pedihusk is prepared, pasted on the parabolic baskets, dried, smoothed, dried again and sanded. Finaly, aluminium reflector paper is glued onto the surface. A bamboo crate holds the parabolic baskets, allowing them to move vertically from 30 to 90 degrees. The model can cook 0.5 kg rice in 35 min. with adjustments every 12-15 min. This is much quicker than solar box cookers.
Further improvements are under way.
