Wow! Anyone else seen home heating via compost? Combined with the Earth Ship and Tiny House movement, this could be a winner! Happy composting!
"Japanese students at Waseda University have designed and built an innovative straw house that produces its own heat through agricultural fermentation. During the cold months, dried straw is composted in acrylic cases within the house using the low-odor Japanese “bokashi” method. The fermentation naturally heats up the house by generating 30° celsius heat for up to four weeks."
