If Only I Had It

What an invention made by a Japanese guy? Hopefully governments from the entire world take this idea as an advantage.

A street light powered by waste seems like a strange idea but if you think about the ratio between city trash and energy needs, things start to make sense.

This street light can composts any waste and uses the methane by-product as a fuel to power the lamps. The compost can then be retrieved to re-green our cities. A wonderful idea but how much trash can it take keep such a system going?
