LABELLE, Florida (CNN) -- Bryan Beer, a citrus grower in southwestern Florida, sees himself as a bit of a pioneer. He's not digging for gold. It's more like he's planting for oil.
Bryan Beer and his family have grown citrus for 40 years. He says farmers need alternatives to diesel.

He is planting a jatropha tree, a plant that can produce diesel fuel and could one day power a 747.
His plans are a little less ambitious; he just wants to plant enough to run his tractors.

"Any kind of relief or help we can get from a cheaper source of oil could impact the agricultural industry tremendously throughout the country, throughout the world," said Beer, whose family has been growing citrus for decades.

Jatropha means "doctor food." It originated in South America, where it was once used for medicinal purposes.
There are three seeds within the golf-ball-sized fruit.
When pressed, its oil can be used as fuel in any standard diesel engine with zero processing, experts say.

Sound like a pipe dream? It's not.
