that's the problem with ethanol (and biodiesel) as it's being implemented now - corn is not the most efficient producer of ethanol (there are woody grasses that do much better) and NO bio-fuel is going to take over from gasoline without significant efficiency gains! sooner or later american car manufacturers will have to realize that 30 mpg will not be sufficient efficiency in the future (or even in the SUMMER, looks like)Insightful Trekker said:IMO the biggest "problem" with alcohol blend fuels is that there's simply not enough acreage available. Even IF 100% of the available land was converted we couldn't get 50% of our daily gasoline consumption equivalent. But it would quickly "solve" the problem as food would rapidly become scarce. :/
And then there are the aldihide emissions that haven't even been addressed yet.
I'm referring to all the billboards I've been passing that advertise 30 mpg as if it's an Amazing! Feat! of Efficiency!james said:30 mpg? When they're whining about having to meet something like a 22.5 mpg fleet average?
insofar as I'm trying to recall from my grad work on benefit cost analyses of alternative fueled vehicles for university fleets, it's the parts that can dry out: things that are rubber, primarily. biodiesel has the same effect but to a lesser degree.b1shmu63 said:There's a good project for an Insighter. Find out what systems and parts are corroded by ethanol and convert their vehicle. Perhaps this would be a good university class project? :idea:
