"Why not use Compost To Heat your home[?] Instead of burning wood for heat, some Europeans now build a compost pile over plastic water lines that extract heat from the decomposing plant material. Temperatures can get as high as 149 degrees. With a circulating pump as the only moving part, the compost heater lasts an average of 12 to 16 mos.–& occasionally up to 24 mos. –providing heat and up to 80% of the hot water for a 1,500 sq. ft. home." -Green Renaissance' via FARM SHOW Magazine
Walt bought me a subscription to "Farm Show" magazine. WOW! He really knows what I like, (though I think the mag. should be renamed "Farm Showoff" magazine). "Farm Show" is a showcase for ingenuity. If you like "Make" magazine, and appreciate do-it-yourself projects on a large, industrial scale, you might want to check out this magazine!
