Lance Crombie: Spokesperson for the Alcohol-fuel Movement

A Plowboy Interview with the farmer who believes in the possibility of energy self-sufficiency through the use of alcohol fuel.

| January/February 1979

Mr. Lance Crombie of Webster, Minnesota is a farmer ... he even carries business cards which attest to that fact. Crombie, however, has a number of sidelines that aren't exactly typical of a tiller of the soil. 

Lance is, for instance, a former cancer researcher who holds a Ph.D. in microbiology, the inventor of a low-cost solar collector, a partner in the firm that distributes his invention, the chairman of the Minnesota State Heart Fund, an associate professor of pharmacy at the University of Minnesota, a member of the New York Academy of Science ... and he's listed in Who's Who in the Midwest and Outstanding Young Men in the Midwest. 

Lance is also a moonshiner. 

A moonshiner? Yep, you read it right. You see, Crombie is the kind of guy who gets things done when they need doin', and he's not at all hesitant to buck the system or throw out the "accepted " answers when he feels that he can find a better solution by himself. 

So-when his family's fuel bills became more than their budget could bear, Lance sat himself down, designed a sun-powered still, and began to produce corn alcohol ... which he planned to use to heat his home and power his farm machinery. 

It wasn't long, however, before his experiments brought about a head-to-head confrontation between Crombie and the Treasury Department's Bureau of Alcohol, Tobacco, and Firearms ... the "revenuers."

Do you mean carbon dioxide that was taken from the atmosphere, or the runoff in the production of the crops? I agree with you on the fertilizers. I don't support corn ethanol since it's dependent on fertilizer and has such a low yield. There are other crops that don't rely on fertilizers and have much higher yields. Besides that, I don't condone large-scale ethanol production. The corrosion you're referring to is likely aluminum corrosion. This can be prevented by using alcohol top lube. Alcohol top lubes are designed for methanol, which is a much more corrosive fuel, but will protect the engine just as well. Biodiesel uses methanol, a product of natural gas processing. You might say that it can be generated with other means such as biomass gasification, but right now it's almost exclusively natural gas-derived. This makes *bio*diesel a misnomer. I think you'd be better off using straight vegetable oil with a fuel heater rather than going to the trouble of producing biodiesel. I don't see how biodiesel is more economical or more ecologically friendly. Biodiesel and ethanol production can use crops that don't rely on fertilizers or pesticides (soybeans and Jerusalem artichokes, respectively, among others.) I'm not sure how cheaply biodiesel can be produced, but the average cost that I've seen for ethanol is about $1.15/gallon.

You're right about the drop in fuel economy. People are obsessed with the BTU comparison of ethanol and gasoline. They don't take into account that ethanol has almost twice the combustion efficiency of gasoline. Its higher octane means that you can increase the compression ratio to 12-18:1 depending on the engine. You can obtain about 22% better fuel economy with a properly converted ethanol vehicle, but the problem is, you won't be able to use gasoline with a high-compression engine. At least, not without an octane booster. I don't condone the use of gasohol.

Kyle Adams, not only is T Brant correct, but there are other problems with ethanol. I don't have the figures in front of me, but the two additional problems I have seen with ethanol are: 1. If you look at the ENTIRE process, ethanol production creates more pollutants than gasoline production (including some that are far nastier) and 2. ethanol is much more caustic than gasoline, so the engine will wear faster. I'm not just talking gaskets and such, I mean the metal parts like the pistons and cylinders too. This is bad not only because the car won't last as long, but also because as the engine wears it looses efficiency and starts polluting more. As best I remember, a car run consistantly on ethanol will have as much wear wherever the ethanol goes (pistons and cylinders, etc but not places like the bearings) at 75-80K miles as the exact same engine run exclusively on unreformulated gasoline would have at about 100K miles. This may not sound like a lot, but it does contribute to more pollution. Think about it this way. When was the last time you saw a car that blew out a cloud of blue smoke as it accelerated from a stoplight? Want to see 20-25% more of them? Since diesels are much more prevalent in the rest of the world than they are in the US, the technology is there to run more diesel cars here, basically at a moments notice. Biodiesel is a much more economical AND ecologically friendly fuel than Ethanol.
