Fuel from human waste 人类排泄物可转化为燃料

Windpower: One form of renewable energy

风能：一种可再生能源 

A new process which turns human excrement into valuable fuel has been developed by scientists in Thailand.

They have produced a reactor which transforms unwanted waste materials into high quality fuel.

Although the process is expensive, the scientists believe it will become more economically viable as natural oil supplies dwindle.

Within the next 100 years, the world's supply of fuels like oil and gas is expected to disappear altogether.

Scientists have spent decades trying to invent ways of trapping so-called renewable energy, such as sunlight or windpower, that will last forever.

泰国科学家开发出一种将人的排泄物转化成高值燃料的新方法。

它们制造了一台可将没用的排泄物转化成高能燃料的反应器。

虽然这种转化很昂贵，科学家们相信随着天然燃料供应的萎缩，这种燃料在经济上会变得可行起来的。

在下个一百年内，世界上的石油和天然气等燃料将会全部耗尽。

科学家们已花了几十年的时间,试图发明能够收集象太阳能和风能等取之不尽的可再生能源的方法
