"Some people walk in the rain, others just get wet." --Roger Miller
Un-Electric Refrigerator
Eggplants can now last 27 days instead of 3. Thanks to Mohammed Bah Abba, who invented an incredible 'Pot-in-a-pot' device that serves as a refrigerator, without the electricity! The device owes its cooling powers to a simple law of thermodynamics: when moisture comes into contact with dry air, it evaporates, causing an immediate drop in temperature. When the water in the sand between the two pots evaporates, the inner pot is kept cool, preserving the goods inside. Mohammed's simple yet profound invention is changing the world -- for one, it allows rural Nigerians to preserve their food!
