如何把便便变成能源?

How To Turn Poop Into Power

Hi, this is Julián from MinuteEarth.
你好 我是《分钟地球》的朱利安
At this very moment, your body (and the bodies of most animals)
就在此时 你和大多数动物的身体
are producing a valuable renewable resource
正在产生一种宝贵的可再生资源
that could be used to power and heat your home.
来给你的房屋提供能量和热量
As it happens, poop contains the raw materials necessary to produce methane gas,
事实上 粪便中含有产生甲烷气体所必需的原材料
which you can burn to produce energy or heat.
你可以燃烧这些气体来产生能量或热量
But you can’t just light your toilet or a pile of manure on fire
但是你不能只点燃厕所或粪便
and plug your phone in.
然后就给手机充电
There are a few critical steps necessary
要利用便便提供能量
between pooping and using that poop for energy.
有几步关键步骤必不可少
First, we need to collect the poop
首先 我们要收集粪便
and in the case of human poop,
以人类的粪便为例
separate it from sewage water at a treatment plant,
从水处理厂的污水中分离出便便
which leaves a goopy poopy sludge
剩下了黏糊糊的粪泥
that’s a bad process as it sounds.
这听起来可不是个美妙的过程
Then, we put the poop in a warm, oxygen-free tank
然后将便便放到一个温暖 无氧的容器中
where some poop-eating microorganisms
那里有以便便为食的微生物
break down the complex carbon-based molecules poop is made of
它们将构成粪便的复杂碳基分子
into a series of simpler and simpler and simpler molecules
分解为结构越来越简单的分子
until finally, other microorganisms happily gobble up these new molecules
直到最后 其它微生物能愉快地享用这些美食
and breathe them out as a gas
并以气体的形式排出去
which contains some carbon-dioxide,
排出的气体中一部分是二氧化碳
but is mostly, and more importantly, made up of methane,
但更重要的是大部分气体是甲烷
the simplest carbon-based molecule.
它是最简单的碳基分子
Amazingly, more than half of the poop by volume becomes gas
神奇的是 按体积来算 一半以上的粪便变成气体
and the rest is a compost-like solid made up of nutrients the microorganisms didn’t break down.
剩下的是微生物不能分解的堆肥状固体
Most sewage treatment plants doodoo this poop-to-gas magic trick
大多数污水处理厂进行便便变气体的戏法
simply to rid themselves of poop!
仅仅为了解决便便本身!
And since methane is a powerful greenhouse gas,
由于甲烷是一种的温室效应很高的气体
most plants just burn it off to convert it into carbon dioxide,
大多数处理厂也只是燃烧便便 将其转化成二氧化碳
which is only 5% as potent a greenhouse gas,
二氧化碳的温室效应仅为5%
and they sell the leftover solids as fertilizer.
他们把剩下的固体作为肥料出售
But a few plants have started doing “double-doody”
但是有几家工厂开始做“双料便便”
by burning the methane in generators to power their operations
他们在发电机中燃烧甲烷 为运转提供能量
or in furnaces to heat their buildings,
或是在锅炉中的燃烧甲烷 为建筑供热
and some are producing so much gas and electricity,
一些工厂产出大量的甲烷和电力
they’ve started selling it.
又开始出售这些产物
Similarly, more and more farms are installing the necessary infrastructure
同样的 越来越多的农场安装所需的设备
to transform their animal poop into methane,
将动物的粪便变为甲烷
which they can sell for profit
他们可出售甲烷而盈利
or use themselves to cut energy costs.
或者用于自己的农场来降低能源成本
which is great,
这个做法太棒了
because most countries, like US
因为像美国等很多国家
generate literal crap tons more livestock poop than human poop.
牲畜产生的的粪便比人类的更多
With this potential poop power
有了这一潜在的能源
we could generate enough electricity to power over 13 million homes annually.
每年的发电量能满足1300万户家庭使用
If we stop wasting our waste and fully embrace poop power,
如果我们不再浪费便便 充分利用便便的能量
our excellent excrement could even become the largest source of power in states
粪便甚至可成为第一大能源
with tons of livestock, like Iowa –
因为在爱荷华州这些州有数吨的家畜
that is, our #2 would literally be #1.
这样便便就成为名副其实的第一
And even if your computer is poop-powered,
甚至若你的电脑用便便供电

NordVPN can fix that by simply switching the country of the server
NordVPN通过改变连入的所在服务器国家
you’re routing your connection through.
