I'm glad to see that the co-solvent in Pure Energy, 2-methyltetrahydrofuran (MTHF), can be derived from biomass (cellulose, as in waste paper, wood pulp, etc.), according to a few references I found:
"...BioMetics is interested in making a derivative of levulinic acid, called MTHF, which acts as a high octane oxygenated gasoline substitute and lowers the price of fuel. During studies conducted by the State of Georgia, The Florida Institute of Technology Southern Bell, and a New York City-based company called Pure Energy Inc., MTHF has been proven to lower emissions in vehicles, said BioMetics' co-founder Stephen Fitzpatrick..." (Anyone know more about Pure Energy's relationship with BioMetics? It appears Fitzpatrick's patent will apply to the Pure Energy process.)
