This is one bike which certainly doesn't let anything go to waste, because it is powered by poo. The creation - dubbed Toilet Bike Neo - is the brainchild of Japan's leading toilet manufacturer Toto and uses a modified lavatory and a mobile laboratory to process poo. The company hopes the travelling toilet, which can reach a maximum speed of 50mph, will help reduce CO2 emissions by 50 percent in the next six years. [Photo/IC]
