I read an article a while back about algae biofuel production. It's one of those techs like the new ceramics that are pretty much hush hush.
Anyway, they grow the algae, skim it off, squeeze it for oil, ferment it for methanol and/or ethanol, then feed what's left, if anything, to the livestock.
It's been applied to clean coal tech to scrub the output from the smokestack to nearly clean. Pipe the exhaust thru the algae tanks.
Very exciting stuff!
