The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past. US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players without wires.
Physics promises wireless power
October 1, 2009 12:00 AM Wireless power transfer is old news--more than a century ago, Nikola Tesla built magnetic coils that transmitted power without cables. But Tesla's coils also tended to expel bursts of superhot plasma.

The Future Is Cordless
Wireless Electricity Is Here
I'm standing next to a Croatian-born American genius in a half-empty office in Watertown, Massachusetts, and I'm about to be fried to a crisp. Or I'm about to witness the greatest advance in electrical science in a hundred years. Maybe both.
A month ago I wrote a post “ World Without Wires ” about the unique material developed by Japanese scientists that can transmit electrical energy to nearby devices without the need for direct contact.
Non-Radiative Wireless Power
WiTricity
WiTricity is an American engineering company that manufactures devices for wireless energy transfer using resonant energy transfer (oscillating magnetic fields). [ edit ] History The term WiTricity was used for a project that took place at MIT , led by Marin Soljačić in 2007. [ 1 ] [ 2 ] The MIT researchers successfully demonstrated the ability to power a 60 watt light bulb wirelessly, using two 5-turn copper coils of 60 cm (24 in) diameter , that were 2 m (7 ft) away, at roughly 45% efficiency. [ 3 ] The coils were designed to resonate together at 9.9 MHz (≈ wavelength 30 m) and were oriented along the same axis.
