BIodigester, a Poo Miracle
How, you ask can poo be a miracle? Well, you take a cow and a bag of plastic and you get food. Simple.. missed one step.. gas. This is another awsome project that peace corps volunteers are doing here in Nicaragua. We (being health volunteers) havn't had the pleasure of being trained in biodigesters, but we decided to go and observe one so that when we get back to the states, we can impliment this low tech miracle when we build our straw-bale home.
Look, its like this. You have a cow, or maybe you don't. You can find cow poo in the streets, or you can use other kinds of poo, including human. You mix the poo with 1 part water, well blended. Then you put it in a bag, where the gas is collected and goes through a pipe that lands at your gas stove. This gas is oderless and can provide about 6 hours of cooking a day based on the size of the bag.
This day, we went to a very small and dry community in Leon, where there were plenty of cows, dirt, rocks and jicaro trees. They already had the hole dug, so the volunteer showed up with her bags, and pipes and we put it together. I wont bore you with the details, but its a pretty nice biodigester and we were pretty excited at the concept. now we just have to figure out how to insulate it against the Utah winters.
