All you need is a constant supply of canola oil, soybeans or chicken fat and you can produce 1.3 million gallons of biodiesel per year with just a click of your mouse. This auction on eBay ends early this morning, so don't let it get away. Look at the potential. Production cost is just 38 cents a gallon, and the seller says the plant will pay for itself in less than two years with current diesel prices government subsidies. To be honest, I'm curious about this venture. How much land is needed for the operation? How many employees are required to keep it going. How much water and other utilities are needed? What would I call my biodiesel fuel?
