Mitti Cool Refrigerator – clay fridge keeps food cool without electricity

An enterprising Gujarati entrepreneur has come up with a novel way to help people keep food cool without needing to plug in an expensive to run refrigerator. His Mitti Cool is a cooler made of clay, which uses the natural cooling effect of water evaporation to do the job.

His fridge has a water compartment on the top and bottom of the unit, which soaks water through the porous clay in order to cool down the contents of the box by up to 8 degrees C. This means that you can keep vegetables fresh for up to a week, and milk fresh for 3 days, which is not bad going really for no power.
