The concept of death ray is a recurrent theme in science: it would be about a Arme projectrice of energy directed in order to destroy an human being or an object. In the Science fiction, it generally appears in the form of a laser Pistolet.

This concept seems to go back to Archimedes, which would have made use of Miroir S to concentrate the Lumière Sun and thus to put fire at Navire S enemies which attacked the town of Syracuse.

Nikola Tesla, scientist American of Serb origin , had offered the projects of a " ray of the mort" with the American services but, not being taken with serious, it sold finally its services with the the USSR where it intended to create reels Tesla surpuissantes called weapons Tesla. With its death, there existed according to the rumor a prototype of " gun antichar" , but FBI could not recover it and it is not impossible that it was carried by a Soviet spy. The weapon was not developed front by the Russian engineers, and one can thus deduce from it that, if the rumor is true, the weapon was not operational.

There nowadays remains always difficult to create a true death ray, since each weapon of this kind would be well too greedy in energy to reproduce would be this only the same destroying potential as a normal Pistolet. However, research continues nowadays, mainly around the Laser.

Weapons plugging with the laser could be developed in theory these last years, but they were prohibited before even as their production does not pass on an industrial scale (a first in the history of the armament!).
