" So why are we using Ethanol instead of Butanol?? PRICE, so far Butanol " has been MUCH more expensive to produce than Ethanol but that could be " changing. BP & Dupont have a pilot project going in Europe to try the " feasibility of changing an Ethanol plant to Butanol. " http://www.technologyreview.com/read_article.aspx?ch=specialsections&sc= biofuels&id=18443&a= i got an error when i tried to pull this pg up. Hmmm, don't know why it worked (and worked from this post). I think BP & Dupont are on to something,,,,and the Shell engineer's refusal to comment on it,,,, HHHmmm,,, " Energy independence (or at least a step in the right direction) is easy " for this country. All we have to do is change the wrong headed thinking " in Washington that makes growing low THC Hemp illegal and use it to make " Butanol. " http://www.butanol.com/ you and they have convinced me of butanol's potential, but imho they still have a long way to go. iirc their production process, while it can work directly on cellulose unlike the common yeast-based ethanol fermentation, has miserable production efficiency. butanol saturates water at 7%; more separates on its own. if they could get their bacteria to live at this level they'd really have something, but it chokes at 2%. That's part of what the research is about, getting the efficiency up. Butanol has much higher energy content than Ethanol (better HP and mileage) and can be transported by the same infrastructure as gasoline. I just wish I could make it in my backyard!! and even if we switched all gasoline vehicles to butanol, we still consume far too much. sufficient acreage to fill current demands would be difficult to come by, never mind the economic spillover as production competes for space with food crops. Not necessarily true if you add low THC Hemp in the mix. There are THOUSANDS of acres of land not really suitable for growing other crops that COULD be used to grow Hemp. We IMPORT Hemp from Canada but are not allowed to GROW it here!! What's wrong with THAT picture?? And shouldn't we do EVERYTHING we can to reduce oil imports??? http://www.votehemp.com But HEY,,, that's just ME!!
