On July 23, 1934 Time Magazine wrote an article about Tesla’s Ray:
“Last week Dr. Tesla announced a combination of four inventions which would make war unthinkable.
Nucleus of the idea is a death ray-a concentrated beam of sub-microscopic particles flying at velocities approaching that of light. The beam, according to Tesla, would drop an army in its tracks, bring down squadrons of airplanes 250 miles away. Inventor Tesla would discharge the ray by means of 1) a device to nullify the impeding effect of the atmosphere on the particles 2)a method for setting up high potential 3) a process for amplifying that potential to 50,000.000 volts; 4) creation of “a tremendous electrical repelling force.”
