After having a solar powered LCD television, now it is a solar powered refrigerator that is on the cards.A MIT spin-off Promethean Power Systems has secured funds to develop a solar powered fridge for rural India by the year 2009.The device uses thermoelectric cooling effect as opposed to freon based cooling, which in turn allows for reduced dependence on diesel generators.The device uses power form a hybrid compressor for cooling effect in addition to 3-5 solar panels.
Promethean estimates that the fridge costs 66 percent less to operate because of the ability to remotely monitor and diagnose problems, as well as the need for fewer fossil fuels.Additionally the design of the fridge allows it to run off the grid and can work for farmers living in rural India who have limited access to centralized grid based power.
