Terry, while I am the one who asked to have some of Deanna's earlier messages removed, she has a solid point here. Hemp is one of numerous organic materials that can be used to produce alcohols. However, a waste product that BFRE is proposing to use, such as wood/paper processing leftovers, and/or landfill refuse(properly sorted), would have both the lowest possible raw material costs, and would not require using fertile land used for foodstuffs, etc.
So, BFRE's approach seems to me the best idea yet to produce ethanol( and/or other products) with the least intrusion on both land use and the environment. Their only remaining hurdle seems to be finances to build its plants. This seems to be the remaining goal of the Bluefire management that must be overcome for success..
