Urine-powered restaurant opens in Melbourne

A Melbourne restaurant with electricity powered by customer's urine has opened for business.

The Greenhouse project uses by-products of agriculture for insulation and energy and was built using recycled materials, according to Smart Planet.

Dutch designer Joost Bakker said: "Urine is incredible for nitrogen, it's so valuable - you only need the urine of 25 people to provide fertilizer for a hectare of crop.

"I have designed the restaurant in reverse. I've started at the end; assessing the waste production, and worked back from there.

"My dream has always been to build a restaurant that creates no waste and now I think I have achieved it!"

Every part of the building is apparently 100% recyclable.
