Old school poo power from the Wayback machine operators at Modern Mechanix.

SEWAGE that costs large cities tremendous sums each year can be turned into a source of power equivalent to thousands of tons of coal! The waste now dumped into rivers or shipped to sea may be used to run factories or to light buildings!...The apparatus for producing gas from sewage consists of two sludge digestion tanks in which the sewage is allowed to ferment. The gases given off are composed of from 25 to 75 per cent of methane, or marsh gas

This great new initiative by the city of Santa Rosa has catapulted this unlikely city into the list of top green cities of the US.

Popular Science did a write up on Santa Rosa, detailing its Geysers' wastewater-to-electricity project. Under this project 12 million gallons of wastewater the city is pumped to the steam fields daily which is then converted into 85 megawatts of power, enough to power 85,000 homes.
