Directory:Abba Pot-in-Pot Cooling System - Nigerian inventor, Mohammed Bah Abba, of Mobah Rural Horizons, has received awards for his simple-to-implement invention of and evaporative cooler consisting of one pot inside another, with wet river sand in between and a damp cloth (or jute bag) on top. When kept in a dry, well-ventilated, and shady location, water evaporates, cooling the inner container.

$25 Fridge Powered By Cooking Fire - The 8-pound prototype zero-emission fridge doesn't need gas, propane or kerosene and is powered by regular fire. TED Video (EcoGeek Dec. 12, 2008)

Magnetic Refrigerator to Cut Power Consumption by 40% - Once Karl Sandeman, a physicist at Cambridge University, has helped resolve the practical issues, the cooling power of the 21st century fridge could come from a 19th century discovery. Camfridge has built two prototype magnetic fridges that promise to cut energy consumption by 40% and save the ozone layer. (Guardian UK Dec. 14, 2006)
