Here's a thought. Grow low THC HEMP and use it to make Butanol. Anybody done any research on that? We currently import HEMP from Canada but are not allowed to grow it stateside because of wrong headed thinking in Washington (HEMP=Marijuana). Low THC HEMP is NOT the same as Marijuana, in fact the two do not even like to grow together. You can NOT get high on low THC HEMP. Looks like there will be more information coming soon on Butanol,,, http://www.runningonfumesfilm.com/resources/ROF+Trailor.mov When I had my engine shop I rebuilt several tow motor engines for a Marble distributor. They had old Toyota 3R engines in them running LPG. They were NOT really designed for LPG. The cylinders and valve guides were extremely worn out! Good thing they had thick cylinder walls as we usually had to bore them .100. We upgraded them to hard valve seats & guides and chrome rings to make them last longer. Most modern engines can probably run LPG OK but I'd think twice before converting an older pre non-leaded fuel motor. But HEY,,, that's just ME!!!
