Exactly, it causes some hard feelings for us yet today. We were just getting started farming when Carter fouled things up. We didn't take those risks because we knew that it couldn't logically work. But if you had a degree from the big AG colleges you could get easy backing from FHA and get on their preferred list, if you were like the rest of the us you had to come upwith 30-50% down payments to get funding thru them. We tried but they said we were profitable enough (no hardship case) to get loans thru regular banks, In reality they basically told you to go to hell! Those who got on the FHA programs are pretty well off today because of the fact they knew how to work the system, the rest of are still sruggling to make it and have basically remained small. We make a living but no frills and many times work extra jobs to keep it. That's why we get a bit ticked when some one blames us for the sins of the Big Corporate outfits.

I heard a guy on a talk show yesterday say they could make ethanol out of (or in combination with?) natural gas. He went on to say it would cost about $2.50 a gal at the pump. Does anyone know anything about this?

Haven't heard of that one. Why would you waste the extra step and processing? Natural gas alone is a good fuel for use as is. very similar to LPG. The pressure tanks involved are already aviliable and non polluting ( no vent fumes or spills) and best of all considerably cheaper than liquid gas.

This is not true. Ethanol is a carbohydrate fuel. Petroleum distillates are hydrocarbon fuels.

The chemical bonds broken in a carbohydrate fuel yield much less energy per bond than a hydrocarbon, and the molecular density of carbohydrate fuels is much lower.

Base energy yield of one gallon of average gasoline is 114,000btu. In best-case efficiency (which internal combustion engines never reach) this equates to 44.79 horsepower-hours per gallon (44 hp for one hour... from that gallon of fuel)


Base energy yield of one pound of ethanol (E100) is 76,100... for 29.85 hp/hrs/gal.


Notice that I say 'Average' for gasoline... that's because gasoline consists of a combination of many compounds... hexane, octane, pentane, butane... in reformulations, hence, different pump ratings. Lower end fuels are down in the 111,000btu range... a larger proportion of the lighter components (those with fewer h-c bonds) make the difference.


E100 is 100% ethanol, which is a chemical compound... the only difference in energy yield, is that Ethanol, being hygroscopic, naturally absorbs moisture from the atmosphere, increasing it's mass, and reducing it's effective energy output.

Here's a good link for 'ya:
