Promethean Power-runner-up winner in MIT’s $100K Entrepreneurship Competition develops solar hybrid milk chiller

Panchabuta has often talked about the  potential of offgrid solar- especially in the telecom space-particularly in the rural telecom and telecom tower space. We have also discussed of the immense potential in the defence and the railways for solar pv based solutions. Opportunities exist for cost effective and innovative solutions in the low and medium temperature thermal collectors space.

Promethean Power  a runner-up winner in MIT’s $100K Entrepreneurship Competition in 2007,  located in Cambridge, Massachusetts has developed a solar-powered refrigeration system for commercial cold-storage applications in off-grid and partially electrified areas of developing countries.

The company has a number of angel investors and investment funds looking to maximize social, environmental and business impact in developing countries including 21 Ventures, Gray Ghost Ventures, Invested Development and Solgenix.

The technology enables food suppliers to store and preserve perishable food items—such as milk, fruits and vegetables—without the need for expensive diesel-powered generators.

Solar Hybrid Milk Chiller runs partly on solar energy and partly on electricity. In April 2010, Sorin Grama and Sam White, the two founders of PPS set up their milk chiller as a pilot project in Savoi Verem in Goa. In just one month the system proved its worth by making it possible to chill milk instantly at the collection centre itself, thereby curtailing the bacterial growth and increasing the quality of milk.

This complete, rural refrigeration system is designed for mission critical refrigeration applications that must operate 24 hours a day, 365 days a year. The combination of solar and grid power provides a necessary backup mechanism and eliminates the need for a dedicated diesel generator. When compared with conventional Bulk Milk Coolers (BMCs), PPS milk chiller provides significant advantages. (Read entire article here).
