A company called Solar Chill has developed an award-winning refrigerator that runs completely off of solar energy. The idea behind the appliance is that perishable goods can now be transferred from location to location without spoiling. One such application of this tech would be the transfer of vaccines, which must be kept cool at all times.

This technology is especially useful to humanitarian groups which must travel in regions with limited gird connectivity or no grid at all. The prototypes have been successfully field tested over an 18 month period, in Senegal, Indonesia and Cuba. Solar Chill is now ready to deploy the technology and is awaiting for the World Health Organization to back approval.

The fridges improve on existing solar-vaccine cooling technology by bypassing the use of conventional lead batteries and not using any ozone depleting or potent global warming substances. You can find out more information — and photos — by visiting their website below.
