Eco Factor: Golf cart runs on methane made from cow dung.
Already running short of fuel, any respite in the existing stocks seems as meaningless as it had ever been. Taking a cue from the exigency, Yamaha has suggested a green solution in developing a methane-powered golf cart. It uses cow dung as fuel. Osaka Gas Co., a close collaborator, lent a hand in providing methane at a low cost. In Katori, Osaka first processes cow poo into biofuel and then turns it into methane gas. Though it is not easy to store, Osaka makes it possible in developing an activated carbon capable of sopping it up at low pressure. The golf cart has a specially designed tank that can hold methane around 30 times of its volume.
