Good morning,
Don't forget that in 1898 Tesla demonstrated a radio controlled boat in New York. Even radio controlled items are commonplace now, that was not the case then. That boat was a toy, a hobby of his if you will. People to this day make replicas of his earlier works.


Telsa also worked on remote operated missles for various goverments, I guess back in the day you could travel the world with less restriction. Because of Tesla we have radar, x-ray, sonar, MRI, wireless transmission, radio ( marconi did not come up with it on his own ) flourescent lighting, television, alternating current ( something that some beleived could not be done ), the list goes on.... If you can find the Complete Book of his patents it is quite amazing. It disappeared from all the Libraries in my area. I used to check it out regularly. One day I could not get it as it was unavailable. I figured it was just checked out, perhaps to another Branch in my state. Nope. Gone for good. Telsa was cranking out useful inventions right and left, some say it was to finance his ultimate goal. A wingless flying craft powered by electricity. His apartment was raided by the Government before his corpse was cold, everthing was taken. Interestingly, on his 81st birthday he revealed some of his thoughts on gravity and how it was affected by electromagnetism. He called it his Dynamic Theory of Gravity. There were other discoveries that he would not speak of. He also critiqued Einstien's theories wich was not popular at the time. I believe both men were correct in many ways. Tesla's theories, if true, were best kept secret from the Governments point of view. Keep in mind that everything you buy from your I-pad to your smart phone is hand-me-down technology no longer needed by the military. Anything you hear about is old news. Anything you are allowed to see in public is old tech.
