Why don't we convert all the animal waste inta fuel? Around here we have lots a hog confinements, there be no reason that that couldn't be converted inta methane gas ta run equipment an electric plants. Done all the time in 3rd world nations. The byproduct a that be natural fertilite. Right now they just disc it in an complain bout how it be pollution. It wouldn't be a total fix ta our energy problems, but like many other pieces sure would help. Just thinkin I guess.
