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. }~h(w^t

The reason this is not a joke is because it is actually happening, but also because cows are responsible for a remarkable amount of global methane emissions, which are a major cause of global warming. It's a real problem. gzD@cx?V

Here's how the fartpacks work: 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. R$Tp8G >j
