JBark said:Maybe it falls between the cracks when it comes to incentives (like the $.50 ethanol and $.50/$1.00 biodiesel incentives), so investors aren't interested? Or maybe there's some patent/licensing issues? That's about all I can think of.
That is exactly the problem. There are no incentives at all for investors. It is already about the same price as ethanol with incentives, so if there were no incentives it would be cheaper right now. It is the byproduct of lobbies. They are special interest by default and mixed alcohol processes don't have a lobbying group so they won't get subsidies so they cannot afford a lobbying group.
That is the problem with legislators being for sale...
As far as ethanol fuel in cars, all you really need to get good efficiency is a turbo and many cars have this. Then just reflash the ECU and most cars with turbos could run on pure ethanol right now.
Edit: To clarify though, you could be correct as well about the patent issue, but I have no confirmation one way or the other.
