Theremoelectric generators are made by Teledyne Energy Systems. 110 W. Timonium Rd. Timonium, MD. 21093 phone 301-252-8220 A typical model from Teledyne will generate 30 watts and consume 33.6 pounds of butane per week. Output voltage is 12 volts at 2.5 A. Typical size for such a unit is 17x25x23 inches and weighs in at a hefty 73 pounds. I found a little *barge* floating in the Tennesse River with one of these units attached. The barge also had a 19 inch radio antenna attached to a box....about a mile upstream was the Brown's Ferry Nuclear Plant! Charlie Thompson Motorola Digital Signal Processor Operation Austin, TX.

All the talk about thermoelectric generators that I've seen have all stated that the devices worked off of either chemically generated heat, or by burning some fossil fuel. It would seem that these devices are idealy suited for use in solar production of electricity. Has any work been done? Are there any models that work with solar heat? How efficient are they? Cost effective? -- Edwin Wiles seismo!sundc!netxcom!ewiles Net Express, Inc. 1953 Gallows Rd. Suite 300 Vienna, VA 22180
