It’s now a few days after Christmas dinner and my wife and I are still trying to put a dent into all the leftovers sitting in our refrigerator. In the western world, we’re lucky that most of us have a large fridge in our homes so we can keep perishable foods fresh, but in rural communities and villages in developing countries, more reliable and effective systems for cold-storage are needed to eliminate spoilage and boost village-based economies.
Promethean Power Systems is a for-profit social enterprise, started in 2007 by Sorin Grama and Sam White, and was the runner-up in MIT’s $100K Entrepreneurship Competition in 2007. The company designs and manufactures refrigeration systems for off-the-grid communities in emerging markets such as India, so rural food suppliers can preserve perishables such as milk, fruits and vegetables without using expensive and environmentally damaging diesel-powered generators.
According to Promethean Power Systems, in India, $10 billion in agricultural produce is lost each year due to inadequate refrigeration, but they’re working on reducing this, particularly in the dairy industry, with their technology. The company’s first product, the Rapid Milk Chiller, features a “patent-pending rapid heat exchanger that cools milk immediately to arrest bacteria growth and maintain milk quality according to international standards,” and does not require a diesel-generator backup.
With the Rapid Milk Chiller raw milk spoilage is eliminated while shelf-life of processed milk is extended, operation costs are lowered because there is no longer a need for a diesel generator, and transportation costs from villages to cities can be reduced as cold-storage at the source minimizes the number of collection trips needed.

Thank you Promethean Power Systems for making our world wonderful.
