Was prohibition of all alcohol introduced so that the Model T Ford wouldn't be produced to run on hemp-ethanol?

No. Ford never made a model that ran solely on ethanol though he did make a carburetor that could be put on the vehicle to make it possible. This is a myth that probably has some basis in fact. Prohibition didn't take effect until 1919 and (maybe) partly because John D. Rockefeller helped get Prohibition passed, changing the goal from temperance with alcohol. But that theory has a problem since alcohol was a waste product from oil production, Rockefeller's main business. So why would he care if it was alcohol he sold to drivers or gasoline? Farmers could make their own alcohol so he'd have a lot more competition so this seems like a good conspiracy theory, if not for the fact that few if any Model T's actually ran on alcohol.

Very interesting theory. Do you know if the dates were very close?

Did prohibition reach as far as industrial uses?

I can see the fight between oil producers and potential ethanol producers. Maybe there were oil men already in government, so it was passed without question - more profit for themselves if they had a large investment in oil.

You would have to look where the vested interests were.

Whenever ethanol is suggested as an alternative fuel it has always faced very stiff opposition.

Considering how much vegatable waste is sent to landfill - if that could be pulped and fermented instead - that would create a massive fuel source, which at the moment is untapped.

Nice try but not this time. Alcohol prohibition was in response to a growing epidemic of public drunkenness. And by the actions of a lot of religious busybodies who felt that God preferred us to have a sober life.

Besides, at the time gasoline was so cheap, ethanol from any source could not compete in price with gasoline.
