This is not a joke, but it is funny. It's also practical. b O}&i3.L;

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. \AI-x$5R *

In other words, cow fartpacks are here. C

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. M| @@

According to the EPA, cow farting (and burping, actually a lot of it is burping) accounts for 5.5 million metric tons of methane per year in the United States — that's 20 percent of total US methane emissions. <f)T*E^5%

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. eq"Xwq *

He doesn't think we're going to live in fart-powered cities before 2070, but he can "imagine a future farm with a couple of these cows used to provide energy to satisfy the farm’s needs." ;2 ?fz@KZ

Just fart-powered farms, then. Excuse me？ 4kV$JV.l
