Nikola Tesla, one of the greatest minds in history. Even after his death, he still finds the way to prove that he was truly a man ahead of his time, this time he's being credited for machines that can be controlled remotely in his patent called Method of and Apparatus For Controlling Mechanisms of Moving Vessels or Vehicles.
Tesla states in his patent that these machines can be used for “communication with inaccessible regions and exploring the conditions existing in the same,as well as scientific, engineering, or commercial purposes; but the great value of my invention will result from its effect upon warfare." The more i read it, the more it sounds like the things drones do today and eventually will do. So be prepared for the Drone Wars.
