In the future, America will harness cow farts to curb pollution and power the grid. It sounds like a joke, but it's actually a real promise. By 2020, dairy industry emissions will be reduced by 25%, largely by persuading dairy farmers to capture methane gas.
U.S. Agriculture Secretary Tom Vilsack announced this at the Copenhagen climate change summit this week. Farmers will be able to buy anaerobic digesters that convert cow, errr, emissions into electricity.

In the late 80's, my (now) wife worked on Capitol hill in DC. She came home from work one day to tell me that she'd had to read a report about methane from cows, and how it was (already) a problem.
Twenty years later, it's still seen as a 'new' and fairly crazy thought.
