Sick. Love the caveman #OOPS#. Ethanol wont work, if you knew how much rainforest they are destroying to produce the demand for it now, you wouldnt even consider it running 100% in the future. Not tree hugging its just a fact that highly fertile soil is needed for this stuff and it can only last for so long, that is: much shorter that fossil fuels! Unless they can sort it out biologically (but probably wont..). I heard in africa on the cheap that they have carbys that start the car with petrol and switch over to ethanol once warm, it requires a lot more heat than petrol to 'boil' or vapourise. Obviously the price of this stuff will go up with demand too, no doubt to ridiculous prices.
