The Problem With Capturing Methane and Selling It

Methane is the gas that powers gas toves and central air eating systems. Most of the methane is being released from the front in the form of burps. You would like their burps on fire, but I don't think that it would be feasible. So you have to somehow trim it in source, prevent it from being produced. Unfortunately, you cannot do it with the cows. It's like they become rebels.
