顶楼主。 sbzeY1 开始以为是笑话,上网一查,是真事,阿根廷国家农技所的项目,并预言2070年后大家生活的城&乡没准会以屁甲烷为能源,原文如下: D^N[=q99&e These new cow fart packs from Argentina could save the world "=FIFf ZHz^S)o\[s S3; lKr This is not a joke, but it is funny. It's also practical. *}7U`Aa *jGPGnSo 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. CK=ARh#|
R3cg2H In other words, cow fartpacks are here. P>|Ef~j >;m{{nj 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. W.IH#`-9E ,b$z!dvhl According to the EPA, cow farting (and burping, actually a lot of it is burping) accounts for 5.5 million metric tons of methane per year in the United States — that's 20 percent of total US methane emissions. f KHse$?_ m.!wsw 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. ,eDu$8J9 ad9EG#mD# Pablo Soranda, INTA press officer, told that the project is more about making a point than it is converting people to a way of life. %S c=_%6 m!;G/s* He doesn't think we're going to live in fart-powered cities before 2070, but he can "imagine a future farm with a couple of these cows used to provide energy to satisfy the farm’s needs." !W(`<d]68: *aI~W^N3 Just fart-powered farms, then. Excuse me? vpi l$Uq ]/a
g*F 我觉得还不是太搞,苹果不也想出iFart吧。祝大家周末开心。 Q~8y4=|#CY TKd6MZhT v3~FR,Kl `6UtxJSx ,^HS`!s[ E 9Kx<\)-GMD
