I remember an article that the Navy was using an algae based diesel fuel, at only $424 a gallon. ......They did get it down to $27 a gallon, but, is it worth it?
I am not an ethanol fan, but does help a little in the corn prices. Right now they pretty low, although, yields have been GREAT so far this year.
If a better fuel is needed, ethanol is not the answer. Compressed natural gas is. Not much for emissions. Not a ton of processing. No need for emission robbing bullchit that is on all of our vehicles now. There is plenty out there. Just need more pipelines to support it. AND to get the car and truck manufactures on board.
