Use collected solar energy from a battery source, or direct, mirrored solar energy, or direct, magnifying glass concentrated solar energy, or even Wind charged or wave charged batteries! Now place the fridge underground in cooler soil leftover from night time cool off, and super insulate the cooling chamber! Do we have a free and Perpetual source of refrigeration Yet? Certainly not by American housewives standards, but the (GRD) great republican depression is in the process of kicking this environmentally unsound royalty off their thrones! In the mean time, we of the third world will survive well with any refrigeration possible and I am certain that an Asian household would not turn their noses up at this chance! </p>Uncle BSat, 10 Jan 2009 16:11:19 -0000http://www.ohgizmo.com/2008/12/10/fridge-cools-with-fire-for-real/#comment-4329538<p>Using a flame to power a refrigerator is nothing new. RV's, boats, and travel trailers have used refrigerators powered by a propane flame for 40+ years. This is just a new take on an old idea...</p>ChipThu, 11 Dec 2008 11:58:54 -0000http://www.ohgizmo.com/2008/12/10/fridge-cools-with-fire-for-real/#comment-4324066<p>Just a correction, home refrigerators don't use liquid ammonia, which is hazardous if it leaks. They use refrigerants such as freon or R12. Ammonia refrigeration is used in commercial settings, and was used to create large blocks of ice for use with the "icebox" found in homes before home refrigeration was feasible. These ammonia refrigerators work, but must be used with special care to prevent leaks.</p>WaltThu, 11 Dec 2008 01:28:27 -0000
