Some say it's the hum of a genius; others believe rolling grasslands are a hideout for the madman and his motor.
Paul Pantone, 62, is a rockstar in a growing community of self-taught garage-inventors.
His claim to fame is a motor that runs on junk.
"As the unit is running, it replicates planet earth and the electrical fields around it," Pantone said.
He said it took him three years to build the motor and a lifetime to understand it.
YouTube chronicles Paul Pantone's rise to fame, starting back in the 1980s when he first unveiled the GEET.
The original motor, by the way, is collecting dust in Pantone's garage workshop.
The garage is like a museum for his disciples.
It is also an assembly line where Pantone manufactures GEET motors to be sold and shipped all over the world.
Pantone charges $795 for a pre-assembed GEET, $40,000 to be a GEET-certified dealer and $3,500 to come to his Oklahoma compound to learn to build one yourself.
Myron Van Tassle traveled from Pittsburg, Pennsylvania to fulfill a lifetime dream.
"I came down here as a religious quest to actually see it," Van Tassle said. "(Pantone) could have just sold out. He could have become a multi-millionaire. But he didn't. He held out to share with me."
Van Tassle is one of many who seem to think Pantone holds the keys to many of life's mysteries.
The GEET is just the beginning.
Garage gurus are replicating Pantone's GEET in backyards across the country running their modified motors on beer, coffee and water.
There are skeptics.
Certified mechanic Charles Lawson is a teacher at Francis Tuttle in Oklahoma City.
Lawson is an expert in alternative fuel engines.
"With the way the GEET motor is set up, I don't believe it would be a reliable source of power." Lawson theorized the GEET runs on gasoline vapors at the top of the fuel tank. "I think that if he had a great idea the manufacturers would be knocking at his door and trying to purchase the information and try to produce it."
That's where you get to the really colorful side of Paul Pantone, a conspiracy theorist with tales of torture at the hands of government captors.
He was committed in Utah, spending three years in a mental institution.
Pantone said they drilled out his teeth as punishment for refusing to sign over the rights to the GEET.
"They said I was delusional. Since none of this knowledge is printed in any public science book it must be delusional," Pantone said.
Is he a recluse with a touch of paranoia or a misunderstood genius?
Many believe Paul Pantone is the Thomas Edison of our day.
There is no agreement on the application for GEET technology but one thing is for sure, the magic motor does seem to work.
