Mansukhbhai Prajapati invented a terracotta clay refrigerator that runs without electricity. He has a company called Mitticool which has produced over 250 clay products including filters, pressure cookers and tawas. It took five years for him to develop the clay refrigerator; now he is working on building a clay house that would stay cool without an air conditioner.
