Will a Future 'World Fuel' be Ethanol Based?

"However, the vehicle manufacturers would prefer a single 'World Fuel', identical in specification wherever their engines are sold around the world, but derived from a range of feed stocks, each appropriate to its region. (Of course, the oil companies may insist on 'almost identical', because some fuel additives apparently have quite incredible marketing properties, vying with Viagra in their potency.) The concept is that 'World Fuel' (VW have already registered the name Sunfuel) could be made from petroleum in Norway, sugar cane in Brazil, natural gas in Dubai, switchgrass on the Great Plains, in South Africa and in the Ukraine, and wheat in Somerset. And guess what? The 'World Fuel' specification bears a striking resemblance to E85. Naturally, engine designers know the characteristics of their ideal liquid fuel, and these are dominated by considerations of overall efficiency, not just combustion efficiency. They are asking Big Oil for a World Fuel, and are hoping most of us will want to use it. "
