In the 1970s Tom Ogle apparently invented a new type of fuel propagation system for cars. Dubbed the "Ogle Carburetor", it was supposedly able to run at an efficiency of over 42km/l or 100mpg, and was said to work by spraying vapourised fuel into the engine, requiring heating cells around the fuel tank to stop the fuel from freezing. One demonstration run was undertaken, the car running from Deming to El Paso, Texas on only 7.5L/2 gallons of fuel.
It is said that oil companies approached Ogle, offering him huge sums of money not to build another machine, to which he refused. Then, in 1981 an attempt on his life was made, with an unknown assassin shooting him, before he died later that year in a suspicious overdose, ruled "accidental".
What actually happened to Ogle? Was his overdose a suicide? Was he poisoned? And if so, by whom? And why?
