I changed things around a bit, and added a few things. It's as new to me as it is to you, but I think it'll work. As usual I'll try to have a variety of topics, but come summer there will be more postings about car events. You can email me at cruisaholic@hotmail.com Keep the shiny side up!

Ethanol lies

It's known I'm not a fan of ethanol; it burns hotter so in older engines you need to install hardened exhaust valves and seats, it draws more moisture so in older cars in ruins gas tanks, it doesn't burn as efficiently as other fuels could, and it's just not as environmentally friendly as people would like us to think. From a story in toeays QC Times I'll use a couple quotes-

"If every acre of corn were used for ethanol, it would replace only 12.3 percent of the gasoline used in this country, Hill’s study said, adding that the energy gains of corn-produced ethanol are only modest and the environmental impacts significant." That means that even if we left no corn for food it would only be a 12% gain.

"Compared with gasoline, it produces 12 percent less “greenhouse” gasses linked to global warming, according to the study. But the researchers also said it has environmental drawbacks, including “markedly greater” releases of nitrogen, phosphorous and pesticides into waterways as runoff from corn fields. Ethanol, especially at higher concentrations in gasoline, also produce more smog-causing pollutants than gasoline per unit of energy burned, the researchers said." So although it makes less greenhouse gas, the drawbacks are obvious. Why not just drill in Alaska, uncap all known wells for production and stop this ethanol nonsense.

The question I've never seen answered very satisfactorily is: Does ethanol produce more energy than is required to create it?

Once you've spent X amount of fuel plowing, planting, cultivating, harvesting, hauling to plant and processing, what's the net gain?

Ethanol consumes six units on energy to produce one unit. My findings are based on a report at this website-

The government based study had a quite a different answer. Heres that story-

The thing that would make ethanol really great is if a high percentage of our power grid came from renewable resouces. For example, using 6 units of wind energy to convert corn into one unit of car-portable energy isn't so bad.

That's not happening at the moment, so we're just left with the political reasons. It helps farmers and provides jobs, and takes a teensy bite out of the amount of oil we need to buy from people we don't like or don't like us.

Whether those are good enough reasons is certainly up to debate...

You're right QCI, it will keep the farmers busy. But with other viable, plentiful sources around to make the fuel, why not use them?
Even certain grasses or woods would make a more efficient poduct.
To make it really great someone should figure out how to lower the pollution using this fuel causes, and figure a way to make it cheaper.
