The project proposes to build and characterise a low-cost ice-maker using nocturnal radiative cooling. It does not use any external energy (electricity or otherwise). The projected cost, if manufactured in large numbers, could be as low as a few hundred rupees per unit. The process of making ice using nocturnal radiative cooling was being practiced in India (and elsewhere) a few centuries ago. During the medieval times, the kings and nobility enjoyed iced desserts such as kulfi in the hot interiors of India. The intended target is remote populations at the bottom of the economic pyramid. The ability to create ice, and therefore, refrigeration processes could have large impact in food-preservation and storage, medical refrigeration, etc.
