Cow power can fuel ethanol innovations

"The goal is to create a largely self-sufficient operation. For example, cattle manure would be used to produce methane to power the operations, including the ethanol plant, which would produce a by-product called distillers grain, which would be fed to the cattle.
The process turns manure from a pollution problem into an alternative energy solution. And it makes ethanol, an alcohol fuel made from renewable sources, into a more cost-effective competitor to gasoline made from depleting oil supplies.
Overall, the Belmont operation would produce beef, ethanol, distillers grain, carbon dioxide, electricity, ammonia products, fertilizer, bedding and potted plants, all of which would be used on site or sold for cash."
