Finally, the human race has come up with something useful that can be created from what is being flushed down the toilet every day. The new Volkswagen Beetle has been converted to run on methane, which has been produced from human excrement. The 2.0 liter car is called the ‘Bio-Bug’, and sources say that it is as efficient on the methane as on conventional fuel and can maintain a top speed of 114 mph (183 km/h).

The affirmation of its performance came from sources at GENeco, a British firm that specializes in organic waste and sustainability.
They say that this method had not been this successful in the past since the methane that was produced from human source, was not clean enough to be used in vehicles, without compromising on performance. Advances in technology have made this possible now. The icing on the cake for green enthusiasts is that this fuel source is sustainable. The car starts off on regular unleaded petrol fuel and automatically switches to the refined methane after the engine is warmed up. Projections from the company say that one facility could provide for 95.4 million miles of auto transportation in a year, which means that CO2 emissions could be reduced by 19,000 tonnes.
