{sniff, sniff} 43% efficient? Smells like bovine byproduct to me.
I also find it interesting that proponents of the big "E" are so quick to overlook or forgive the loss of mileage seen by dilluting gasoline. Or they just brush it off by saing 'just rebuild the engine with higher compression.' Riiiiiiiiiiiiiiiiiiiiiiiiiiight!!! I'm going to spend $3,000 to $6,000 to rebuild a perfectly running engine so I can save a few pennies per gallon at the pump. Let me get RIGHT on that.
BTW, bumping the compression up to best use ethanol will make the engine useless for gasoline at the CRs I've seen recommended. Seems it'll be pretty hard on starters. And I'm pretty sure it's illegal from a federal emissions standpoint.
