As long as bio fuel burns our food supply, I'm against it.

Many farms run on recycled animal waste, converted into methane. I read an article a couple months back about a farmer here in GA who have isolated/modified the enzyme from a cows digestive system that breaks down vegetation and creates the methane.
The article went on to say methane can now be produced from those modifyed enzymes without the need for the cow, or its waste product.
If it is factual, we can save our corn for food and convert everything from grass, tumble weeds, kudzu or anything plant in mass scale (Billions of barrels/day)
If I come across the article again, I'll post it.
