Intel uses Resonant induction to power a device without wires

Posted on August 26th, 2008 by Richard Catto 1,943 views

On Thursday August 21 2008, Intel demonstrated lighting a 60 watt light bulb on stage using a fancy get up of two circular coils aligned about three feet apart.

They’re using what is called a Wireless Energy Resonant Link and instead of transferring power with bolts of lightning, Intel’s device uses resonant induction to induce a current to flow on the receiving coil which in turn powers an attached device.

A 60 watt globe draws more power than the average laptop so this device could be used in lieu of a standard recharger.

Intel’s device is 75% efficient, meaning that 25% of the power is lost during the wireless transfer process.

Readers on slashdot have idly wondered if this magnetic field might have unintended side effects such as wiping hard drives clear of data.

Intel is also researching a robotic application called an electric field sensor that allows a robotic hand to gauge the size of an apple, grasp it and then drop it into an outstretched human hand that it is also able to sense.

   This is nice that more companies are getting involved in the wireless electricity revolution.

   I know that a company called PowerBeam is also involved in the wireless era and they safely transmit energy through optical energy, instead of the copper wires and the electro-magnetic field.

   By using optical energy they can send energy over long-range distances. Their device also has a safety system so that it shuts down if anything is close to the beam.

   I’m not exactly sure how efficient their system is but if you’re interested in more info check out http://www.powerbeaminc.com

   Won’t that cause more cancer than cellphones and high tension wires are alleged to do?

   @Steve Hayes: Probably.

   I suggest you construct yourself a tin foil hat as you will want to protect yourself not only from the above but amongst others, cordless telephones, microwave ovens, Wi-Fi devices, iBurst, Sentech and Alien mind probes.
