WiTricity, Wireless Electricity With No Brain Scrambling Side Effects

The idea of creating wireless electricity was actually around in 1890 and was invented by Nikola Tesla. The basic idea consisted of an electromagnetic induction that states that electric current flowing through one wire can induce current flow in another wire. Tesla’s idea, however, did not work.


Now a team at MIT, headed by Marin Soljacic has found a way to make wireless electricity, AKA WiTricity, a reality. Much like Tesla’s original idea, Soljacic created a pad that contains a powered coil that creates a magnetic field. In turn this magnetic field induces a current to flow through a secondary coil (any portable device like a phone or BlackBerry). This electricity then charges the device’s rechargeable battery. Everything is done wirelessly and in some cases a battery may not even be necessary! Thanks to WiTricity.

One of the benefits of using magnetic resonance is that biological organisms are invisible to and unaffected by magnetic field. In essence, the receiving coil “tunes” to match the powered coil in order to charge. And because its based off of resonance, the WiTricity is fairly omnipresent so long as it is located in the general area of the appliances. WiTricity is also highly efficient over various ranges and can exceed 90% for certain applications. It is designed to work with variety of products and systems and can handle a wide range of power levels. Not only that but it also comes in a variety of shapes and sizes and can be built directly into the product, eliminating the need for a an external power source.

The first announcement of a WiTricity partner product is expected toward the end of 2010.

  1. The mistaken and insulting reference to a Tesla failure of wireless electricity is not taken lightly by those who actually read history books. In 1898, the Electrical Review featured a photo of Nikola Tesla holding a large gas-filled lamp with no filament that was being lit wirelessly. Furthermore, the Electrical World and Engineer, March 26, 1900, p. 792 includes an article on “A Tesla Patent on Wireless Transmission” which explained Tesla’s concept of wireless transmission. My book, Harnessing the Wheelwork of Nature: Tesla’s Science of Energy (Valone, Adventures Unlimited Press, 2003) includes a half dozen articles by PhD scientists on the validity and high efficiency (95%) of Tesla’s well-published wireless electricity transmission as opposed to every method available today, including Witricity. Futhermore, this Wifi Walker article deceives the public by not including any gaussmeter measurements, which very likely exceed even the most generous “guidelines for limiting exposure to time-varying electric and magnetic fields” published in Health Phys. 99(6):818-836, 2010 which amount to 1 mT for occupational exposure and 200 microtesla for residential exposure in 1 Hz to 100 khz.
