Yeah to all you whise asses who "know" Teslas history and the creation of his Coil, shield and possibly other weapons here is a REAL history LESSON from a serbian, because he was a serb too: When he invented that, he wanted to give it all to the Kingdom of Yugoslavia because i quote: "I created a mighty weapon for my beloved country, that force that i practicly tested, will give Yugoslavia great power and nobody would be able to stop it. I am overjoyed, because i am helping my country". And he would put up generators across the country to generate power for the weapon. He would put 3 in Serbia, 2 in Croatia and 1 in Slovenia i think. That is the very short version of the story, but the entire story is long and im bored to type it here.
