Mark Steudal, a Peace Corps volunteer in Kenya, sends us this:
This is a picture of a Bio Gas generator. It is basically a 9 foot deep well that is filled with manure and water from the nearby cows. A huge drum is then placed into the well. The drum catches the methane gases that are generated from the manure decomposing, which due to the pressure of the large drum are pumped into the house by a underground hose. This family did most of their cooking on the gas, didn’t need to use firewood or buy charcoal (except when making chapatis of course).
