[Biofuel Frank]

Hello all! As you can tell from my name I'm obsessed with renewable and alternative fuels. I've spent countless hours of research into this topic, and have determined that I really dislike ethanol as fuel choice for America because of its means of production, it's not sustainable and there is always the classic food vs fuel debate. Methanol is produced from natural gas in America which defeats the purpose of making a methanol fueled car, when CNG autos are now mainstream (which ford and some other auto makers did in the 90's) that's leaves us with 2 more mainstream alcohols, propanol and butanol. Propanol is essential rubbing alcohol, which is great for medical purposes but it can't be produced from renewable sources. Leaving us with probably the next fuel of the future for gasoline engines. Butanol is around 90% the energy of gasoline and very similar to gasoline in terms makeup, it can be put directly into almost all gas engines with no modification, that means non- flex fuel cars can run on it. The main problem is producing it, in world war 2 a German man developed a method called ABE, it produces acetone, ethanol, and butanol. This can be done by bacteria and fermentation, similar to ethanol. The problem is the low yield of butanol, my question is do you guys think that all the fuels from ABE can all be dumped into a fuel tank and combusted? If not, do you think butanol with more research can replace ethanol, like I do? I'm not going to make the post any longer so if you feel the need to please do a little outside research, and comment I love alt fuel discussions!!
