It is said, in his patent alternating current (ac), each with a horsepower alternating current (ac), he can charge $2.53 royalty, because of the huge profits, many people want to buy his patent right, but the tesla did not sell, but will tear up the patent, the whole world can be free to use, this kind of behavior is really admirable,
His contribution to the electric field is not just an alternating current, also known as the great invention of the tesla coil tesla coil can send wireless power, also is the precursor of the modern radio communication technology and the best performance of wireless charging technology, now most of the mobile phone supports wireless charging, the wireless charging is not the real wireless charging, should you put support wireless charging technology mobile wireless charger of 0 cm to 20 cm above the distance is to charge properly, and tesla coil induction distance is far more than the range of 0-20 cm, for example: when tesla think ` I use tesla coil to global power `, now know that the power of the tesla coil,
Especially famous works in the history of mankind - dynamic theory of gravity, was finished, he when he is too advanced in terms of ideas, no one can transcend, he remained single all his life, everything will be all to his love of science, because nikola tesla was too severe, he studies, others could not continue to develop, so be erased by textbook!
