A cow poop-powered tractor. The British company New Holland has developed a tractor that runs on liquified methane. This is New Holland’s step toward carbon-neutral farming. With an aim to provide a “sustainable, more productive, and more profitable future for farmers.” The New Holland T7 Methane Power LNG tractor has 270 horsepower and is expected to perform as well as the diesel-powered tractor. The T7 is also equipped with precision farming technology to improve productivity. Cow dung is collected and stored in a covered slurry lagoon. Where it is processed into liquefied methane and cryogenically frozen and later used as fuel. Should all farmers switch to methane-powered farming tools?
