Ethanol for fuel

There was an interesting article in the news tonight about the production of ethanol for fuel. They said that there is huge amounts of corn now growing in the state of Iowa that is slated to be made into alcohol for fuel. They also said that huge expensive ethanol factories are springing up everywhere. There are some reasons why this is all going to be a waste of time and money. The reasons are as follows. First of all the growing of corn requires fuel for the tractors and machinery. Some experts estimate that it will take more than a gallon of gasolene to produce one gallon of alcohol. Further more the price of corn has taken a steep climb and therefor the price of food has gone up. This looks like another fiasco. What do you think?
