I think alcohol is a great alternative when it is NOT produced from food stocks. But when you factor in the emissions concerns created by the agriculture needed to grow those food stocks, it's not as clean as some believe. And yes, I believe you need half again as much alcohol compared to gasoline to produce the same amount of energy?

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
