Cows naturally produce a gas called methane that can be burned by humans.
Cows release methane as they chew, burp, and fart, but mostly when they burp.
A herd of cows can produce up to 450 gallons of the stuff every day.
Cow dung releases methane as it deteriorates, as well. What is left can be used for rich, non-smelly fertilizer.
Methane is an extremely potent greenhouse gas, and much of it is produced as a result of cattle farming.
Because most of the methane from cows is produced when they burp, it is not currently practical to extract methane from cattle.
