Josef Papp

Josef Papp (born 1933?, Tatabanya, Hungary – died April 1989, Daytona Beach, Florida) was an engineer who was awarded U.S. patents related to the development of a fusion engine, and also claimed to have invented a jet submarine.

Alleged submarine journey

On August 11, 1966, a fishing boat off Brest, France spotted someone floating in the water, clutching an inflatable life raft. They fished him out and found that he was dressed like a pilot with a flight helmet and goggles. He was barely coherent and badly bruised. When questioned, he identified himself as Canadian Josef Papp and claimed to have just bailed out from a submarine. When asked where the crew was, he replied that he was alone in his submarine and had just crossed the Atlantic in 13 hours.

Media storm

Thus started a media storm of controversy. Papp, a Hungarian-Canadian engineer, claimed to have built a special high-speed submarine in his garage that was propelled by a special underwater jet engine. However, on his maiden voyage across the Atlantic he encountered a stability problem and the submarine sank. The media ridiculed him, calling him a madman, a liar and a fraud. He protested against these accusations and even wrote a book entitled "The Fastest Submarine", which described the design process, construction and the voyage in his own words. What the book does not describe is how the submarine in question worked. Nor did Papp ever reveal this secret or attempt to prove that it could indeed work. The media found it all too convenient that the submarine had sunk, that two plane tickets to and from France had been found in his pocket, and a man resembling him had been seen boarding a plane to France some hours earlier. So the story of Josef Papp fell into relative obscurity, as did his book. The submarine was never found.

Papp's work

But it soon became apparent that Papp in fact built something, since the photos in his book clearly show a vehicle. [ [http://www.museumofhoaxes.com/comments/papp.html Joseph Papp page with submarine images from "Museum of Hoaxes" Website] ] Papp's alleged submarine was built as an elongated cone, looking like a long needle with a cylindrical engine compartment in the rear. The pilot sat nearly flat on his back in front of this compartment, with a small periscope built into the hatch. The theory was that the sleek shape would create a sheath of air around the submarine, like a supercavitating torpedo, allowing it to reach 480 km/h (300 mph), which he claims it did.

The engine was supposed to run off of very little fuel. Papp was notoriously paranoid, keeping his workshop under lock and key and covering every component in plaster to stop people from taking photographs. As a result the media claimed that his submarine was made of papier-mâché.

However impressive the photographs of his "submarine" may have been, David Ansley in the San Jose Mercury News reported that "The London Daily Mirror said Papp admitted it was a stunt, that he couldn't bear to admit to his friends that the submarine wouldn't work."

Other inventions

Papp's other claims were no more credible. Among other things he claimed to have invented a fusion engine and a car engine that ran off a mixture of noble gases consisting essentially of an inert gas mixture of helium, neon, xenon, krypton and argon, with argon constituting approximately 17% of the mixture by volume.

Papp was issued several U.S. patents for these inventions, including his noble gas fuel mixture (U.S. Patent Nos. [http://patft.uspto.gov/netacgi/nph-Parser?TERM1=3680431&Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=0&f=S&l=50 3,680,431] , US patent|4428193, and US patent|3670494). The existence of these patents appears to contradict claims that Papp took his "secret" fuel mixture to his grave. [ [http://www.museumofhoaxes.com/comments/papparticle.html Reprint of David Ansley: "The Dream Machine", "San Jose Mercury News", August 27, 1989 ] ] Nonetheless, no one has ever publicly demonstrated a working version of his "noble gas engine". The entire incident is considered by most scientists to be a hoax. Indeed, the exposition in the abstracts of these patents correspond well to Richard Feynman's descriptions of the pseudo-scientific gobbledegook Mr. Papp presented to his audience for an ill-fated demonstration in 1966, in which his engine exploded, killing one man and seriously injuring two others.
