顶楼主。 nYA@t=t0 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: E[IjeJB5 These new cow fart packs from Argentina could save the world Ev%_8CO4e `1O<UJX U"SH
fI: This is not a joke, but it is funny. It's also practical. `B1r+uTP~ DL*/hbG 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. q 4Rvr[ gAFu In other words, cow fartpacks are here. /"Z6\T9 /y2)<{{I 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. q:iB}ch5R \Uz7ar#, 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. D]P_tJI %1\MW+ 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. j'\!p):H Ne!0 `^`~ 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. W{)RJ1 &1ZqC; 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." 7{"urs7 T &"_5?7_N Just fart-powered farms, then. Excuse me? #0:N$'SZ ~4T:v_Q7g 我觉得还不是太搞,苹果不也想出iFart吧。祝大家周末开心。 o+}>E31a sYMgi D @N(*1,s2 }{oZdO :gwM$2vv ^9jrI
