In most underdeveloped countries, people use mud pots in which they keep water to drink chilled water. These countries are poor and cannot afford refrigeration. In Africa, water is used to cool vegetables and food products when a refrigerator is not available. That idea is now used to create the Thermodynamic Cooler concept which is actually directed at emerging economies.

It needs no electricity and the water cooling helps to preserve food without a hitch. The design comes with a stackable design where the bowl can be used to store fruits. Thanks to a damp cloth everything remains fresh and cold and this would help the poor people of the third world keep their food clean and safe without having it spoiled by tropical temperatures. The only hitch is that water needs to be added from time to time.

Unfortunately these “emerging economies” are mostly countries in Africa and Asia where there is a severe shortage of water. While trying to save electricity, you would only be wasting water. Thus, I guess no energy can be created or destroyed and can only be transferred from one source to another, like an annoying scientist once said. You try to save electricity but end up spending water! Great design indeed!
