Nikola Tesla was a Serbian electrical engineer, he in my opinion was one of the greatest innovators of all time. without him the world wouldn't be the same. his inventions are what make him the man he is today, ac current for example. alternating current is used everywhere as you are reading this you are using AC current in your computer or phone. fascinating eh? it gets better. one of his inventions involved wireless electricity, the Tesla coil, a mechanical marvel, a was to create power from nothing, i could go into detail on how a tesla coil works but that would take hours to explain and frankly i dont think anyone has enough time to sit down and listen.
nikola tesla didnt do this for money, glory, fame, infact when he came to the US all he had was clothes that could fit in his small bag. the reason where because he was interested in electricity. simple as that. just like i am interested in cooking. he believed he could improve the studies of electricty and expand the field, and so he did.
to prove what his inventions can just do i recommend this video
