* Video: [http://www.youtube.com/watch?v=z2AP5PnSo1c Biogas-powered Electrictal Generator in Myanmar.] Brief video shot at the Myanmar Baptist Convention agricultural training center near Yangon in early March. Biogas brewed from wastes produced by a few hogs located just above this location is piped to an electric generator. Each day, there's enough biogas produced to power the 3 kw generator for 45 minutes in the morning and another 45 minutes in the evening. The generator, in turn, powers lights as well as an electric pump that extracts water from the center's well for storage in an elevated tank. The stored water flows by gravity to spigots throughout the farm. Saw Hei Moo, who directs the project, estimates that the biogas system costs about $350 with the generator running around $300. Toss in perhaps another $100 for pipe, cylinders and other types of essential apparatus.
