Meet Dorn Cox. He grows sunflowers in addition to many other things. He has figured out that four acres of sunflowers will yield 300 gallons of fuel at a cost of approximately $1 per gallon to produce. He presses the seeds for their oil while tilling the fibrous plant material back into the soil. The solid by-product (cake) of the pressing is used for animal feed. Nothing is wasted or thrown away! The oil is refined through a multi-step process in a repurposed soda distributor’s panel truck, whose compartments afford the perfect set-up for the multiple refining tanks. The fuel moves from tank to tank by way of compressed air, so no emissions are created in the refining process. It is totally self-contained. Dorn calculates that his biodiesel gives back 3 to 5 times more energy than it takes to create it. To read more, CLICK HERE!
