ScienceDaily (Nov. 19, 2009) In everything from computer processor chips to car engines to electric powerplants, the need to get rid of excess heat creates a major source of inefficiency. But new research points the way to a technology that might make it possible to harvest much of that wasted heat and turn it into usable electricity.

That kind of waste-energy harvesting might, for example, lead to cellphones with double the talk time, laptop computers that can operate twice as long before needing to be plugged in, or power plants that put out more electricity for a given amount of fuel, says Peter Hagelstein, co-author of a paper on the new concept appearing in November in the Journal of Applied Physics.

Every day people send perfectly good natural insecticides and soil amendments to the landfill. Many of them are not gardeners and dont really realize the gold theyre throwing away, but some of them are gardeners who just have not yet discovered the beneficial properties contained in kitchen wastes. I, too, was a doubting Thomas until solid evidence made me a believer.
