And for those who might think that fart gas, otherwise known as bio
gas, is unrealistic, here is the Mother Earth News "Plowboy Interview"

AIR, it's possible to get somewhere in the neighborhood of 2-6 CF of methane

the US. The idea can make sense in some situations but is far from a
universal solution.
