This looks like a completely uneconomical mess to me.

Ethanol will hopefully be a short-lived product as it is by far not the best alternative out there...but the marketing realities call for it to be around awhile. The perfect biofuel would never make it to market if the consumer had to do even the most basic of modification to their vehicle in order to use it.

O.K. I'll bite. If all I have to do is the most basic of modifications to my vehicle, it would probably be cheap, and so easy just about anyone with a pulse could do it. If the perfect biofuel came along in this scenario I'd be all over it, provided I didn't have to pay more for it that what I currently pay, and that it was actually a cost-effective solution unlike ethanol.

Any more ethanol in the current fuel at the pump, and you may as well kiss your engine goodbye (along with any drivetrain warranty), unless of course it's already flex-fuel capable.
