CHARLESTON, W.Va. -- This guy hasn't been to a gas station in eight years.
He also hasn't paid an electric bill in almost nine years. With a tank of cooking oil in the bed of his diesel truck, he said he can drive from his home in Barbour County to Florida and back.
"I tell you what. There is a major drawback of heating the house and driving the cars on the cooking oil. And that's that you constantly stay hungry. Because you're smelling the French fries all of the time!''
Meet John Prusa, electrical engineer and self-professed mad scientist. He said he remembers that when he saw gas jump from 89 cents to 99 cents a gallon, he made it his personal goal to become energy independent. He's very proud of the fact that it's now been 8 ½ years since he's visited a gas station.
"I don't care if it's somewhere in the oil fields or whether it's a refinery in Texas or whether it's a local guy at the local gas station -- the greed is international. It doesn't have boundaries. It will always show up. And getting rid of that aspect was probably the driving factor of me doing this -- that I'm not at the mercy of somebody else's greed.''
Prusa said a couple years ago when he had two kids in college, five cars on the road and was heating and cooling a 2600-square-foot house, his family saved $20,000 each year. But, he said, everything comes with a price.
"It's not free. Because you have to do Dumpster diving -- you have to get dirty. Look at my hands. It's not free. Then you spill the oil, your wife slips on it -- it's not free, trust me. But the bottom line is that you have the great satisfaction of being independent.''
