What you wrote was the truth. It is called NAFTA. As part of the treaty Mexico was required to remove the tariffs and trade protection that protected the mexican farmers from low priced imports. Massive amounts of cheap US corn were dumped on the Mexican market and the small mexican farmers that were just barely making a living growing corn couldn't compete when the price of corn in Mexico fell by 70%. It is estimated that a million small farmers lost there land and livelihood as a result collapse of corn prices. Of course then after those farmers were gone the price of corn went up in the US when the price of gas went up to more than $4, but there was no one but the big producers left in mexico to grow the corn and prices went through the roof. BTW, There were no jobs in Mexico for the displaced farmers so you no where they headed. That same scenario has played out over and over again in third world countries. Surplus corn has not been used to feed the poor it has been used to drive the poor deeper into poverty. The best thing you can say about ethanol production in the US is that it has removed the US corn and other grains that have been dumped on the world markets. And the taxpayers of the US and Europe are the ones to blame. It is the taxpayers that have poured more than a trillion dollars in farm subsidies since WWII to fund the destruction of rural economies all over the world. > A. 76,000 = BTU of energy in a gallon of ethanol > B. 116,090 = BTU of energy in a gallon of gasoline > There is no magic that will make it more, although engines designed to > run ethanol specifically can perform well.

A gasoline engine at its very best uses only 25% of the energy in the fuel. That means only 29,000 of the 116,000 BTUs is used to propel the car down the road. An ethanol engine that operates at 40% efficiency will use 30,400 BTU's to propel the car down the road. Which engine will make the car go farther down the road? The problem with gasoline has always been it is an inherently prone to thermal inefficiency. Adding ethanol to gasoline makes it possible to overcome that problem. The energy content of a fuel does not predict what mileage the vehicle will get. The most important predicter of fuel economy is how efficiently the fuel can be utilised to produce mechanical power. -jim -jim

Nobody but you and Mr. Bean said anything about thermodynamics. Thermodynamics may predict how much heat is produced from a gallon of fuel. But thermodynamics does not predict how far you will travel on a gallon of fuel. If you think that the amount of heat produced and gas mileage are the same thing you know little about IC engines. If thermodynamics could predict real world mileage of vehicles they wouldn't do any fuel economy testing. They would just calculate the mileage for each vehicle. |
