[网讯]科学家研制出牛屁包收集甲烷用于发电 [复制链接]

奥巴马政府声称，将采取措施，减少牛的肠胃气胀，从而减少牛的甲烷排放。于是，科学家开始对牛的腹胀问题重新研究，他们打算收集牛的有害排放，转变成“绿色”能源。 4thLK8/c5g

阿根廷科学家表示，已经为这个问题找到了解决办法——可以用来收集牛屁的“屁包（fartpacks）”。 q/~U[.C

阿根廷的科学家介绍说，将屁包的管子直接插入牛的消化道，每天可收集300升甲烷气体，转化的能源可供一辆汽车跑24小时。插入牛胃里的管子用来把甲烷气体收集到屁包里，挂到牲畜栏房顶上进行分解。阿根廷国家农业技术研究所已经研究这种装置很多年，目前它仍处于概念论证阶段。 e|u|

除了这种屁包以外，科学家还在为牛研制新的饮食，以便它们更容易消化食物，科学家打算把牛食用的谷物换成紫花苜蓿和三叶草等植物。早期的一项研究发现，研究人员通过使用单宁酸，可以将牛的甲烷排放减少25%。

新的发明！

黑科技啊

可以极大地解决能源问题

太搞笑了，纯扯

顶楼主。 A$ %5l  
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： @va{&i`%A7

This is not a joke, but it is funny. It's also practical. ]+)z}lr8 C

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. @I}:HiF

In other words, cow fartpacks are here. YD2M<.U

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. H? N!F7s

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. n|NI]Qi*

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. k#`.!yI,

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. 6k"Wy3/

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." Zb-TCS+3l

Just fart-powered farms, then. Excuse me？ 7^Uv1ezDR

我觉得还不是太搞，苹果不也想出iFart吧。祝大家周末开心。 0sVCTJ@

简单的事也用心去做

很有趣的研究

实际运用不太现实

只要用心，一切皆有可能。 wi:]oo#
