Reviving Tesla's Wireless Power Initiatives.

The article informs that scientist Nikola Tesla first imagined the wireless transmission of power. He holds several patents related to the wireless transmission of energy. It is the part of his wireless world system, that would send both information and electricity around the globe. The most extensive use of wireless power transfer can be seen in passive RFID tags. A Powercast transmitter can send radio frequency (RF) signals, which is converted into electricity to charge small devices like phones or cameras by the receiver. A team of researchers led by professor Marin Stoljacic at the Massachusetts Institute of Technology (MIT) have come closer to Tesla's vision by outlining a way to juice bigger devices without wires. They rely on magnetic induction and resonance to transfer power.
