Technologies

• A compressor-free refrigerator - Engineers at Penn State have developed a new method of running a refrigerator that doesn't require a compressor. Rather, it changes the level of organization in a solid to change the temperature. This change in entropy results in heat-transfer. (Slashdot Commentary) (Pure Pedantry; August 12, 2008)
  

• Pot-in-Pot Non-Electric Cooling System - Nigerian inventor, Mohammed Bah Abba's award-winning, simple-to-implement invention of and evaporative cooler, consisting of one pot inside another, with wet river sand in between and a damp cloth on top. When kept in a dry, well-ventilated, and shady location, water evaporates, cooling the inner container.
  

• Acoustic Stove, Fridge, Generator Could Aid Third World - The "Stove for Cooking, Refrigeration and Electricity," or SCORE, could help improve the health and quality of life for the two billion or so people in the world who cook over open fires. The SCORE thermoacoustics technology promoted by a multi-institutional project converts heated gas into sound waves which can be used to cook, cool, and/or generate electricity.
  

Research and Development

• Promethean Solar Refrigerator - Promethean Power Systems is developing a clean, quiet, solid-state solar-powered refrigeration system for commercial cold-storage applications in off-grid and partially electrified areas of developing countries, using thermoelectric cooling modules and solar photovoltaic (PV) panels. (Video Series link) (Engineering TV; Jan. 6, 2009)
  

• $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)
  

• A Plastic That Chills - Thin films of a new polymer developed at Penn State change temperature in response to changing electric fields. Qiming Zhang, an electrical-engineering professor at Penn State, who reported the new material in Science last week, say that it could lead to new technologies for cooling computer chips and to environmentally friendly refrigerators.(MIT Technology Review; August 11, 2008)
