f 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: <Fb3\T L These new cow fart packs from Argentina could save the world %[ 4/UD=7 iC&=-$vu xEaRuH c This is not a joke, but it is funny. It's also practical. ~u1ox_v`%( )'\Jp
7*3 Argentina's National Institute for Agricultural Technology (INTA) has invented a way to convert cow flatulence into usable energy, and it involves putting a plastic backpack on a cow. Ea1{9>S =nOV!!
In other words, cow fartpacks are here. HyXw^ +tsj &$ F0 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. c"t1E-Nsk +O3zeL 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. +Tc4+q! }gyJaMA 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<]<x? MK[l*=\s 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. 4NbX!"0 I"@X~Y7} 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." Mm-FdP
m 8rXq-V_u Just fart-powered farms, then. Excuse me? gBHev1^y )7=B]{B_ 我觉得还不是太搞,苹果不也想出iFart吧。祝大家周末开心。 (?xGlV`n {f#{NA5 BDxrS q,H +GI[
