This is just MHO, but, here goes.....
The Hemp fuel thing looks to me, from the wording and the site it is on and the links and other stories on that site, like something from High Times magazine. Just another backdoor way to try and get pot legalized. "Yeah man, grow the stuff, you can smoke the bud and make gas out of the stem."
Its all plant oil and you can do the same from corn or soybeans or many other plants, Im sure. No reason to legalize drugs to make fuel. Again, thats JMO, and Im sure there are others out there. (BTW, I dont think legalizing marijuana is that bad of an idea. It could be taxed and take some revenue burden off the rest of us, but that is a much better reason than using fuel as an excuse.) It would probably be a good fuel source, if what this article says is true. But how credible is it? Its hard to believe anything that comes from alot of these "pot papers". They have tried every angle for years and will do about anything to get it legal.
The turkey gut thing looks interesting. Dont know if it will make it or not, but sounds good. I think that is where our future should be for fuel. Renewable resources. Corn, soybeans, other crops that Im sure could be grown in less than perfect farmland to make oil and now the turkey gut/used grease thing. If that can be used, then Im sure that the leftovers from the big packing houses for beef and pork could also be used.
I dont know whatever happened to the gasahol thing. I know a fella in Iowa that was good friends with my dad that went big into that. He already owned alot of farmland and built many stills to produce the alcohol. Everything was going good, then it just went belly up. I dont know what stopped that, unless it was the oil cartels or something.
