'Death Ray' For Planes

The New York Times

September 22, 1940 Nikola Tesla, one of the truly great inventors who celebrated his eighty-fourth birthday on July, 10 tells the writer that he stands ready to divulge to the United States government the secret of his "teleforce," of which he said," airplane motors would be melted at a distance of 250 miles, so that an invisible 'Chinese Wall of Defense' would be built around the country against any enemy attack by an enemy air force, no matter how large. This "teleforce" is based on an entirely new principle of physics, that "no one has ever dreamed about," different from the principles embodied in the in his inventions relating to the transmission of electrical power from a distance, for which he has received a number of basic patents. This new type of force Mr. Tesla said, would operate through a beam one- hundred-millionth of a square centimeter in diameter, and could be generated from special plant that would cost no more then $2,000,000 and would take only about three months to construct. A dozen such plants, located at strategic points along the coast, according to Mr. Tesla, would be enough to defend the country against all aerial attack. The beam would melt any engine, whether diesel or gasoline driven, and would also ignite the explosives aboard any bomber. No possible defense against it could be devised, he asserts, as the beam would be all-penetrating. High Vacuum Eliminated The beam, he states, involves four new inventions, two of which already have been tested. One of these is a method and apparatus < section not legible eliminating the need for a "high vacuum;" a second is a process for producing "very great electrical force;" third is a method of amplifying this force, and the fourth is a new method for producing "a tremendous repelling electrical force." This would be the projector, or the gun of the system. The voltage for propelling the beam to its objective, according to the inventor, will attain a potential of 80,000,000 volts. With this enormous voltage, he said, microscopic electrical particles of matter will be catapulted on their mission of defensive destruction. He has been working on this invention, he added, for many years and has made a number of improvements on it. Mr. Tesla makes one important stipulation. Should the government decide to take up his offer, he would go to work on it at once, but they would have to trust him. He would suffer "no interference from experts."



In ordinary times such a condition would very likely interpose an insuperable obstacle. But times being what they are, and with the nation getting ready to spend billions on national defense, at the same time taking in consideration the reputation of Mr. Tesla as an inventor who always was many years ahead of his time, the question arises whether it may not be advisable to take Mr. Tesla at his word and commission him to go ahead with his "teleforce" plant.
