What happened

A Japanese designer has developed a technology that generates tiny amounts of electricity from everyday materials such as soil, water, food and construction waste.

Why it matters

Glinting in the night, halfway up a hill in Japan, the greenhouse-like ‘Ku-An’ test lab is lit by electricity harnessed from 1,500 wooden boxes of soil and compost.

Common ground

Designer Satoshi Nakagawa has long battled sceptics, but believes that the technology powering the 800 LEDs has a role to play in solving humanity's energy conundrum.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
