"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
Cob houses can be a great option for survivalists or preppers looking to build a second shelter out in the country, or even as a main home. If you’re thinking about going the cob home way, make sure to check local building codes – the USA hasn’t really caught up with the trend yet and some counties make it very difficult to build a home like this…even though it’s just as safe (or safer) than a “traditional” house.
