This kills me every time:
Making food into fuel makes no sense at all.
News flash -nobody's starving. My family is planting corn on acreage that the FedGov paid them to lie fallow under the PIK program for many, many years, and selling the additional bushels to the distilleries. Normal corn production (how much field corn are you eating, anyway? Mexican tortillas use white corn...) is no less than it was prior to ethanol's debut. Our black angus beef herd is also fat, dumb, and happy.
And all that vitriol completely negates the fact that distilleries around my neck of the woods are built with the capability to switch over to cellulosic ethanol production, anyway. Folks may giggle and snort, but corn was the easiest short-term attempt to create a biofuel using technology that our alcoholic forefathers pioneered. It worked in the gas tank of Jimmy Johnson as he was running shine prior to his NASCAR days, and it works fine in my E-85 truck. I haven't run a drop of regular gasoline in over two years now, and when I run it in my high-compression 383 stroker '53 Chevy pickup project, I'll also drive it to and from the family farms - Jimmy Crap Corn, and I Don't Care...
Now, you want a good biofuel source, I'd start looking at liquifying and cracking Soylent Green, say, from the Berkeley area. Just get the hemp out of the mix, first.
