Hi Thomas .. I'm not a fan of corn based ethanol either .. I don't see it as a food vs fuel issue; however, as the DDGs are a great animal feed and will be utilized as such .. Ethanol is just such a poor substitute for gasoline .. I'm hoping that the market for ethanol is restricted to MBTE replacement as an octane enhancer and maybe some limited E85 in the crop growing areas .. From an energy density perspective and ability to integrate with the existing transportation fuels infrastructure; butanol seems a better choice .. While the potential resource base is huge; oil shales are the least attractive of the petroleum derivatives .. Let's exploit the tar sands and heavy oils ( Orinoco ) first .. Scalability is a real issue for all currently contemplated extraction schemes from these reserves and not likely to offset depletion losses from conventional crudes .. It's a big problem if one's intent is to maintain the status quo going forward .. I'm thinking some combination of bio-fuels, new nukes, large scale hydro, wind/solar/tidal, will allow a more or less stable transition to a predominately electrified future transport grid .. Triff ..
