I do understand the second generation using non food crops would be a better route but now that we know there is enough oil/gas for the next 100 years these hard times may slow down second generation ethanol development.
I thought it was interesting how Henry Ford built his first generation of vehicles to run on ethanol. Sounds like flex fuels is nothing new.![]()
Of course, when Henry Ford first started churning out vehicles, there weren't a lot of them around. Great amounts of ethanol weren't required. The amount we require today to make a significant impact is a number of degrees greater. And therein lies a problem with ethanol (even second generation ethanol) as a fuel source. How can we possibly grow and transport enough biomass in an economically feasible manner to meet current needs?
As far as the numbers I have seen, even second generation ethanol production requires more energy to produce than it can deliver. With more research, maybe we will see a net gain. But we're not there, yet.
