Ethanol can be a useful solution, but corn-based (indeed, any high-starch based) ethanol not only cannot be part of the solution, but will be, now and forevermore, only implemented by very high levels of taxpayer (NOT gov't!) subsidy, no matter how often ADM and that crowd say otherwise.
Why does everyone assume that ADM will hold onto corn based ehtanol production? If cellulose based proves to be more profitable they WILL move their production in that direction so that can make more money.
Granted right now they are raking it in hand over fist thanks to subsidies, but if/when this cheaper method starts jacking their market, ADM will WILL move toward that direction. I'm no fan of ADM but they will be a huge part of the ethanol movement in this country. At least until the price of oil drops back below $30 bbl. After that who knows whats gonna happen in the energy market?
