Argentina’s “#Methane_Backpacks” Turn Cow Farts into Green Energy
Cows farts, albeit stinky, are rich in methane gas, a greenhouse gas and a fuel source. Trapping those cow farts though is like trying to catch a wave upon the sand, but now researchers in Argentina are tapping into this un-utilized potential and capturing the gas with methane collecting backpacks. A tube stuck right into the cow’s rumen collects the gases and stores them in an inflatable sack on their back. Later the methane is purified and compressed so it can be used to generate electricity, run a refrigerator, cook or even run a car, all while keeping the methane out of the atmosphere. While the concept still needs more testing and development, as well as a serious look at the ethics, this is the beginning of #Cowpower, the newest form of renewable energy.
