Wow, it’s really great to have so many posters here who can provide some professional and informed opinions.
I have a question for ya’ll. Petroleum prices are going up, but if we were able to generate our own non-food crop based biofuels, would it be possible for farms to be self-sustaining? That is, could they “grow” their own fuel, and put that fuel to work harvesting food crops? This sounds almost too good to be true, but if the amount of fuel generated can produce an amount of energy greater than all the energy costs that went into producing it, that wouldn’t be so far-fetched, would it?

I can’t claim to be all that informed. I do remember back in the early 1980s when a number of farmers brewed their own alcohol for machinery and vehicles. They used everything you could name, and some were really inventive. Garbage, paper, wood chips, grass, crop detritus, cane. You name it. They all seemed to have a good time doing it, but they didn’t do it for years and years either. As far as I know, none of them blew themselves up. But that was all just “home made” stuff, not necessarily viable commercially, because they put their own work into it. So it wasn’t really “free” because if you did that on a larger scale, you would have to pay people to do it (and probably have a lot better equipment as well as an energy source for distilling other than wood a farmer cuts himself) They didn’t have any transportation costs, either. Make alcohol, carry it to tractor, pour it in. That was their transportation system. So, I guess the answer is that it’s clearly possible as an “on the farm” thing. Beyond that, I don’t know.
