顶楼主。 G9\EZ\x! 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: D899gGe These new cow fart packs from Argentina could save the world ~\2;i]| 49o\^<4b Q}=fVY This is not a joke, but it is funny. It's also practical. [!W5}=^H $( S*GF$S 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. PmHd9^C P"b8!k? In other words, cow fartpacks are here. +|6`E3j% iBucT"d] 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. zei6S d$}&nV/A) According to the EPA, cow farting (and burping, actually a lot of it is burping) accounts for 5.5 million metric tons of methane per year in the United States — that's 20 percent of total US methane emissions. UanEzx% U<Vy>gIC Here's how the fartpacks work: tubes run from the backpack into the cows' rumen (or biggest digestive tract). They extract about 300 liters of methane a day, which is enough to run a car or a fridge for about 24 hours. 0}B?sNr j(sLK
& Pablo Soranda, INTA press officer, told that the project is more about making a point than it is converting people to a way of life. Z%#^xCz;w> F"I*-!o He doesn't think we're going to live in fart-powered cities before 2070, but he can "imagine a future farm with a couple of these cows used to provide energy to satisfy the farm’s needs." <P-$RX J<rlz5': Just fart-powered farms, then.
