What can you do with cow dung? We can think of at least one green car option: transform it into biomethane and use the gas to power a golf cart. This is what the engineers at Yamaha in Katori, in Chiba Prefecture. Osaka Gas Co. provided the methane at a low cost. It was then stored in a special tank filled with activated carbon capable of absorbing the methane at relatively low pressure. The tank was developed by Osaka Gas Co. as an alternative to a high-pressure pump and tank. The town of Kator
Looking for a sustainable fuel to power your fleet of semi trucks? If you are a dairy farm, we'd bet that the one thing you've got too much of is cow manure. Hilarides Dairy happens to have this exact problem, and it's turning it into a solution. Over 10,000 cows will happily provide enough dung to generate 226,000 cubic feet of biomethane gas each and every day. That amount of gas (literally) is enough to cut 650 gallons of diesel fuel fuel per day from the farm's fleet of vehicles.
