I think the initial numbers is that if we utilized the majority of available land in our country. We could produce enough ethanol to replace around 30% of our gasoine useage. That number can only go up, as planting, and land-use efficiency goes up. And that doesn't factor in change in our transportation efficiency.

Now, imagine lots of vehicles with the E-flex technology, or similar (i.e. potential for fuel-less travel). Then later on as the tech gets improved, and upgraded....well, you get the picture: We will need to use less fuel anyways. So that 30% grows to 40%, and 50%, and 60% - beacuse there's less fuel to displace. So Ethanol can become a very large portion of the solution. Along with Biodiesel, and Hydrogen, and God-knows whatelse they come up with.

Well said, well said. My only question is whether or not E85 capable cars can also be ran on cellulosic ethanol??? Now that might be a stupid question, but I'm just wondering. I mean if plants are being used in either scenario included with alcohol and a small amount of petrol I don't see why not??? Maybe I just answered my own question???
