A MIT spin-off has created a solar powered refrigerator that can bring cooling to those far from the electric grid – especially those in developing countries like India and China.
"Promethean Power Systems has developed a solar-powered refrigeration system for commercial cold-storage applications in off-grid and partially electrified areas of developing countries. … store and preserve perishable food items … without the need for expensive diesel-powered generators"
" … a for-profit enterprise. We believe that creating a cost-effective solution for cold-chain food distribution in emerging markets is an excellent business opportunity that could deliver enormous social and environmental benefits."
" … study revealed a large business opportunity in India for an efficient cold-storage solution targeted to the dairy industry … Cold-storage at the village level minimizes the number of collection trips and reduces transportation cost in half. Today, the only alternative is to use commercial refrigerators with diesel-powered backup generators, a no-win situation that further exposes the dairies to escalating energy prices. "
