Argentina’s National Institute for Agricultural Technology (INTA) has invented a way to convert cow flatulence into usable energy, and it involves putting a plastic backpack on a cow.
According to the Environmental Protection Agency, cow flatulence and burping, accounts for 5.5 million metric tons of methane per year in the United States, that’s 20% of total US methane emissions.
Yeah, but how much is that per cow?
According to the INTA experimentation, tubes run from the backpack into the cows’ rumen (or biggest digestive tract). They extract about 300 liters of methane a day, which is enough to run a car or a fridge for about 24 hours.
I’m guessing really large fridge or really small car.
I’m still not buying ketchup as a vegetable, though.
