Well, Paul.

Actually I do know the difference between industrialised feedlots and small, integrated, mixed farms, and between cattle ranchers and poverty stricken Nepalese peasants. So do the people we're in touch with. They're not just theorising about these things, they're doing them, and many of them haven't been to a gas station for years. Neither have I.

Indeed it's easily possible to use crop by-products and crop wastes for on-site energy production without cheating on soil fertility maintenance, the same as it's possible to sell crops off-farm without cheating on soil fertility maintenance. On a real farm there's always an ample array of choices and options on just what shall be deemed "production" and what "waste". If there were any basis to your view of it everything would have to be returned to the soil and I wonder what would be the point of farming in the first place. Organic farming is all about sustainable surpluses.

Indeed there are farmers in the US using $200 DIY stills to produce 5 gal/hr of 190-proof fuel ethanol without robbing the soil. On a slightly larger scale, more than four thousand people download Floyd Butterfield's on-farm fuel ethanol plans every month. And so on. I'm not talking through my hat but there's no point in my arguing about it.

We do a lot of work with sustainable biofuels and now it's sweeping the world, whether other people notice it or not. But it's just a part of our project, we don't think it's the most important part, we've always been much more interested in Albert Howard. We wouldn't do biofuels at all if they weren't entirely compatible. Fear not, I'm sure Sir Albert's old bones don't rattle a lot whenever someone says "biofuel". It's possible to do anything badly, but it's a delusion to be blind to all other possibilities.

I must admit I'm a little puzzled by the quite widespread resistance to sustainable biofuels among organics people. After all it's the same issue. How can biofuels be sustainable if they're not grown sustainably? And which crop cannot be grown sustainably? Conversely, how can organic growing be sustainable if it's still plugged into the fossil-fuel energy system when it could so easily be independent, via air, fire, water, and, most certainly, earth. Off-topic on a soils list? Well, if you insist, and of course I'll defer and desist after this reply.

It's strange that this resistance seems to be virtually confined to the US, where it's rather common, while elsewhere it might be just the odd individual. Are you aware that Dennis Avery takes the same stance as you do?

Regarding Robert's comment on $27 per gallon gasoline, you can find those ideas explored in old Biofuel list messages from around five years ago and later. If humanity were capable only of reacting we wouldn't have made it past the autralopithecene era. People are just as capable of foresight and acting upon it, even if only in their own lives and communities and not instantly at the national level in the full focus of the mainstream media.

That's how change happens, via small minorities working away quietly in advance of events, not by whole communities suddenly waking up when it's much too late. Nor by "getting the message out" until a democratic majority votes for it with their pockets and ExxonMobil says Hey, you win, hands over the keys to the castle and mooches off with their $400-million golden handshakes to devote their attention to golf.

People have seen the energy crunch coming for 35 years, much longer in some cases. It's hardly begun, but it's already too late to start thinking about it only now. No need though, sustainable biofuels production is already happening all round the world, the appropriate technology solutions are developed, being used and being developed further in a wide range of conditions, and it's not at odds with the needs of the soil, quite the opposite. Those involved think it's too late to stop it.

Despite appearances, what industrial cartels and governments might do might not be very relevant. Big Central is the wrong paradigm for biofuels, no matter how big and powerful they might be or how much they can tilt the playing field their way. There's a role for it, but only a secondary one.

In the same way, the food miles issue turns out to be just a fuel miles issue in drag, and that marks the end of the road for a so-called food production system that has to truck a cabbage a thousand and a half miles before selling it. Sad about the inevitable fall-out no doubt, but apart from that, so what? The sustainable alternative is also already happening all round the world, and has been since Albert Howard's day.

Energy and food are much more closely linked than most people imagine.

Thankyou, I'll bow out now.

Best wishes

Ok, but the question remains, what makes it practical or economical for them - if it is - and would it be practical across the board for family farms in different climates, and those without large numbers of livestock? I'm suspecting it's most practical for large feedlots which we really find abominable.

Where they have plenty of livestock and few alternatives for fuel, they might find biogas practical.

Pimentel as you know headed a government panel to study the economics of ethanol, and I see no obvious reason to throw him out and credit the later studies by similar panels. I just don't give much credibility to followup government studies and corn growers' studies to justify enormous subsidies for corn ethanol. To me, it sends up red flags all over the place. My personal view on that.

But we're not seeing the whole economic analysis of it. The startup cost may be low, but the opportunity cost is overlooked. In other words, how much do they lose in not selling or using their ethanol crops for food, compared to what they save by substituting ethanol for gasoline?

That page states "A sustainable mixed farm can produce all its own fuel, with much or possibly all of it coming from crop by-products and waste products without any dedicated land use, and with very low input levels."

But I have a problem with that. Which byproducts and crop waste is *not* needed to return to the soil? None I can think of. Again, there's the economics of it, the opportunity cost. Anything used to produce fuel could instead be returned to the soil directly or composted. Is anything gained when you turn crop waste into ethanol and have to truck in organic matter to take its place in soil building?

>No, livestock do though, and that's what's done with most of the corn

But we don't need more livestock; we need to eliminate corporate feedlots and devote more land to people food instead of grain for cattle. If this country cuts way, way back on beef (and other meats) as it ought, there won't be many livestock to eat that ethanol-processed corn. Of course, it could still be composted ;-)
