The eco-beetle that runs on gas, just not that kind of gas

Eco Beetle VW

Developed by a team of British engineers, the Volkswagen Beetle converted Bio-Bug is Britain’s first car to run on a mixture of gas and human waste, making it a practical alternative to electric vehicles. Apparently the energy efficient car only requires the output (for want of a better word) from the lavatories of just 70 homes to power it for 10,000 miles.

I wonder what its exhaust smells like?
