Here's a video playlist outlining my compost hot water system so far:
This all stems from a Frenchman named Jean Pain. I discovered Jean Pain's composting method back in 2008 while browsing for info on composting toilet systems. All that existed then was a single article in the Readers Digest from 1982. So I started a Wikipedia article, defended the notability challenges, negotiated copyrights for images of Jean Pain, and watched it grow from there. A few months later, Youtube user TaranikiFarm copied and uploaded the 1980s documentary, The Power of Compost, focusing on Jean Pain's method, made back in the early 80s as well. Jean Pain drew 18 months of energy from his large compost pile. Heating and gas, 100% of his energy needs, including his truck and machines!
Now, clearly such a method is not for everyone, but it is for me. Energy rates in parts of Australia are expected to rise over 60% in the next 3 years, and I don't intend to be left out in the cold as energy poor either. My outspokeness and impatience with work always gives me a sense of precarity in regards to income, so I think its a good idea to skill up on alternative living. Besides that, its just good fun :)
Next step, getting methane gas from it for cooking...
