Nikola TDBR

These are some of the Tesla's inventions that I've found online.. (using the LMGTFY method :P)

Alternating Current -- (Together with ) This is where it all began, and what ultimately caused such a stir at the 1893 World's Expo in Chicago. ever-after between the vision of Edison and the vision of Tesla for how electricity would be produced and distributed. The division can be summarized as one of cost and safety: The DC current that Edison (backed by General Electric) had been working on was costly over long distances, and produced dangerous sparking from the required converter (called a commutator). Regardless, Edison and his backers utilized the general "dangers" of electric current to instill fear in Tesla's alternative: Alternating Current. As proof, Edison sometimes electrocuted animals at demonstrations. Consequently, Edison gave the world the electric chair, while simultaneously maligning Tesla's attempt to offer safety at a lower cost. Tesla responded by demonstrating that AC was perfectly safe by famously shooting current through his own body to produce light. This Edison-Tesla (GE-Westinghouse) feud in 1893 was the culmination of over a decade of shady business deals, stolen ideas, and patent suppression that Edison and his moneyed interests wielded over Tesla's inventions. Yet, despite it all, it is Tesla's system that provides power generation and distribution to North America in our modern era.
Rotating Magnetic Field (1882):Tesla's first breakthrough came when a professor in his native Croatia (he was ethnically Serbian) told him it was impossible to create a motor powered by alternating current (AC) instead of direct current (DC). Tesla was sure this wasn't the case, and after two years of performing experiments in his mind, the solution came to him like a bolt of lightning: a rotating magnetic field that would allow alternating current to power an engine without being first converted to direct current.
AC Motor (1883): Tesla carried detailed plans for this AC motor in his head (a particular talent of his) until he could build a physical model the next year. The alternating current created magnetic poles that reversed themselves without mechanical aid, as DC motors required, and caused an armature (the revolving part of any electromechanical device) to whirl around the motor. This was his rotating magnetic field put into practice as a motor; within two years, he would use it in AC generators and transformers as well.
Tesla coil (1890): The electrical coil named for its inventor is one of Tesla's showiest inventions, and he used it to its full dramatic extent in demonstrations held in his New York City lab. The coil uses polyphase alternating currents -- another of Tesla's discoveries -- to create a transformer capable of producing very high voltages. It brought forth impressive crackling sparks and sheets of electric flame that impressed the electrically savvy and the layman alike. They're primarily used for entertainment today.

Wireless charging explained: What is it and how does it work?
Wireless charging technology has been around for more than 100 years.

By Lucas Mearian
Wireless charging has been around since the late 19th century, when electricity pioneer Nikola Tesla demonstrated magnetic resonant coupling – the ability to transmit electricity through the air by creating a magnetic field between two circuits, a transmitter and a receiver.
But for about 100 years it was a technology without many practical applications, few wireless charging techniques are used after the 100 years we still depends, depends for what? While charging at a distance has big potential, the public face of wireless charging has until now remained with charging pads. So we depends here on pads. No free solution is created yet , the solution in which we not depend on charging pads.
Here now I create a solution for all this dependency, you don't need pads for charging just your wearable like phone are in your hands and it automatically charging battery from long distances power senders (Source). No matter is is just 4 feet distance we can receive Power for charging from hundreds of kilometers.
This is the real Power transmission or dream of Sir Nikola Teslas.
Think on it...........

My invension involves energy harvester i.e EMI (Electromagnetic interference) from Radio Waves of mobile network. This circuit can be used in mobile phone to charge battery automatically. Furthermore, this invension will help in charging laptops, tablets or any type of gadgets at any place where mobile network is available without using any charging device.
