GCC: Cow Power!

Continuing with my Green Car Congress obsession, here's an article on cow manure:

Biomethane from Dairy Manure Could Power 1M Cars in the US:

There are 8.5 million cows in the United States, each producing enough manure to potentially generate about 30 cubic feet of biomethane per day, which could replace significant amounts of natural gas at today’s prices. If used as vehicle fuel, biomethane could power a million cars.

OK, so I don't really care about manure of methane. I just wanted an excuse to link to Ms. Cow Power!
