In a bid to understand the impact of the wind produced by cows on global warming, scientists collected gas from their stomachs in plastic tanks attached to their backs.I just hope they haven't run into any patent infringement issues.
Guillermo Berra, a researcher at the National Institute of Agricultural Technology, said every cow produces between 800 to 1,000 litres of emissions every day.
As loyal Fat Knowledge readers know, over 2 years ago I dreamed of the possibility of collecting the methane from cows. As I wrote:
What if instead of letting the methane go into the atmosphere where it causes harm, what if you capture it and use it as fuel, lessening our dependence on fossil fuels (methane is natural gas for those of you that didn't take o-chem)? I'm imagining a sci-fi like device with a tube that is inserted into one of the cow's stomachs that draws off the methane gas into a balloon on the side of the cow.It brings a little tear to the eye to see that the dream has become a reality.

Update: Now with video. Still not clear to me how it connects to their stomach.
Update #2:This article has a picture of how the tube attaches to the cow.
Also, they state that a cow gives off 28-35 (lets call it 33) cubic feet of methane a day, or 1,000 cubic feet a month. The EIA put the commercial price of 1,000 cubic feet at $12.45 in April of 2008. At that price, you could capture $150 of methane per cow per year.
