Inventor Mysteriously Dies After Creating Device That Lets Any Car Get 100 Miles Per Gallon

While some people believe the story of American inventor Thomas Ogle is a myth or urban legend, the reality is that Ogle designed and implemented a “vapor carburetor” that allowed a vehicle to achieve over 100 miles per gallon of gasoline in 1977—with no carbon emissions.

Sadly, Ogle’s invention would never see the light of day.

After surviving an assassination attempt, Ogle subsequently died under suspicious circumstances only months later.

“Are you afraid of oil companies or the Arabs coming after you?” journalist Ron Laytner presciently asked Ogle in 1978—three year prior to his death.

“No. Not any more. I’ve had too much publicity. If I’d kept my invention a secret I might be worrying. But there’s nothing to worry about any more,” said Ogle.

The saga began on April 30, 1977, as Ogle unveiled his invention to the world in a consumption test using a 1970 Ford Galaxie, which unmodified achieved roughly 13 miles per gallon. The test saw the inventor drive a journalist 205 miles on just two gallons of gasoline—achieving over 100 miles per gallon.

The results of his road tests were so spectacular that the car was inspected for hidden fuel tanks. None were found and those who drove with Ogle confirmed that they had never stopped to refuel.

Subsequently, the amazing technology was publicized in the El Paso Times, Argosy Magazine, The Philadelphia Enquirer, and many other publications—bringing Ogle’s invention nationwide attention.

The modified car was extensively tested and engineers found no evidence of fraud, although naysayers point out that there was no scientifically valid testing of the device to independently corroborate the invention's purported capabilities.

Ogle’s Vapor Fuel System—US Patent # 4,177,779—Fuel Economy System for an Internal Combustion Engine was set to revolutionize the auto industry.

Abstract: A fuel economy system for an internal combustion engine which, when installed in a motor vehicle, obviates the need for a conventional carburetor, fuel pump and gasoline tank. The system operates by using the engine vacuum to draw fuel vapors from a vapor tank through a vapor conduit to a vapor equalizer which is positioned directly over the intake manifold of the engine. The vapor tank is constructed of heavy duty steel or the like to withstand the large vacuum pressure and includes an air inlet valve coupled for control to the accelerator pedal. The vapor equalizer ensures distribution of the correct mixture of air and vapor to the cylinders of the engine for combustion, and also includes its own air inlet valve coupled for control to the accelerator pedal. The system utilizes vapor-retarding filters in the vapor conduit, vapor tank and vapor equalizer to deliver the correct vapor/air mixture for proper operation. The vapor tank and fuel contained therein are heated by running the engine coolant through a conduit within the tank. Due to the extremely lean fuel mixtures used by the present invention, gas mileage in excess of one hundred miles per gallon may be achieved.

One expert proponent of Ogle’s invention was Professor Gerald Hawkins of Texas A&M University, a mechanical engineer with a background in gas dynamics and aerospace study.

“This is no hoax,” said Dr. Hawkins, “Ogle eliminated the carburetor and achieved what the gasoline internal combustion engine was supposed to do all along – to operate off fumes.”

Ogle’s invention, dubbed the “Oglemobile,” was set to revolutionize the auto industry.
