Intel showcases wireless power
  • 20 Comments
by Brian Krepshaw on August 21, 2008

Intel remotely fired up the audience today at the IDF R&D Forum Keynote by wirelessly powering a light bulb from a distance of 2 feet away. Using a signal generator and a power amplifier, wireless power transfer was effectively showcased by Alanson Sample from Intel Research, Seattle. Transmitting 60 watts at 75% efficiency, the technology lit up a small light bulb perched upon a set of odd-looking coils.

Originally developed at MIT, the demonstration worked by creating resonance between two magnetic fields. A comparison would be the famous example of an opera singer maintaining a high note long enough to shatter glass. This was the first public demonstration since the prototype was first developed last year.

With a four-year time frame in mind, the technology could eventually be used to power everything from laptops to cell phones. If the technology can be scaled for ubiquity, it “might make more sense to charge a capacitor instead of a battery”. When leaving an area supplied by wireless power, future devices could run off of quickly charging capacitors.

  • Putting Tesla’s ideas to work…almost 90 years later.

  • I Hate to say this but can that thing give you an wireless shock because that would be something

  • Not new: http://blog.tice.de/beitrag.php?file=2007_06_09_0914 Intel just makes more PR about it. But hopefully now it’s getting serious. Finally without cables! Would be great!

  • Looks like a great step forward..

    Just out of curiosity, I feel it should be forced magnetic resonance, not a natural resonance. In a natural resonance, power is conserved – that is why many companies are waiting for superconductivity at room temperature to become a reality. Since a 60W bulb is lit up, it should be forced magnetic resonance eating up equal amount of energy (other than heat loss – hence 75% efficiency). Also, it seems to be an example of the very first experiment done by Michael Faraday – where he passed a physical magnet through a closed loop of wire. Here we are passing a virtual magnet (getting generated out of running electricity in the bigger coil) through another coil.

    Does it also mean that this device is NOT transmitting a TRUE WIRELESS POWER? – that’s my immediate thought. I think it cannot work long distance with this method.

    Any comments?

  • Well… Ain´t seen Tesla´s being quoted anywhere… what a shame…

  • nothing new.. everyone knows magnetic field generates current.
    so.. it’s just an evolution based on the particular dictum. the trick is making it work at a commercial scale. Please be informed that I am not in anyway intending to diminish this achievement. It’s a great step forward, make it work!

  • I made a Transmit-Receive Modified Coil type Antenna
    Interference signals can be seen on TV at 6 ft.
    The range for Power Transmission can be contemplated for 10 kms atleast.Samples are available

  • Hey vidy….good for you jerk. no one cares. take a class in marketing.

  • The difference is that TESLA would give the people FREE ENERGY, thats properly why it has taken over 90 years to make it!! anyone else is just a copycat looking for a profit!
    Tesla was a man of the world.

  • I’m sure wireless power is totally harmless, nothing to worry about! http://notnews.today.com/2008/08/23/intel-demonstrates-wireless-power-for-the-home/

  • Wi-Tricity is something I’m very excited about — and have written about several times.

    Personally, I think it’s a game changer on many levels.

    The guys that figure this kind of technology out would solve a lot of problems and free up dwindling resources, such as copper wiring as just one example…

  • May be there is something wrong with my eyes, but I saw a lots of wires there.

  • Nothing New Hear – Just as many have posted.

    Tesla did this long long ago.

    I did this two months ago as a fun demo for my wife.
    Very easy to do.

    Too bad this idea is not compatible with today’s household technologies, etc.

    Too bad the wealthy businessmen suppressed this when Nickola Tesla tried his best to make it publicly available.

    Too bad INTEL is taking credit for Tesla’s work.

    • May you please share the details ? How many watts and upto what distance ?
      I would like to do the same. It looks interesting ?
      One of the things that I am curious is to how to generate power at such high frequencies (MHz) ?
      Will look forward to hear from you.

      Cheers.

  • What happens when you put magnetic disk drives; pacemakers, and a long list of other devices near the energy transmitter’s magnetic field?

    Oh, I get it, these devices will be out-dated by then?

    The new Legal flourescent bulbs – the ones containing mercury – will work nicely.

    No more warm glow of incandescent lighting.
    Just the cold, toxicflourescent light – with skin cancer causing UV rays, I guess. But then, who cares if the ultraviolet causes skin cancer? Most office workers get their dose day or night anyways.

    Ignorant, poorly educated sheeple will follow along the path to slaughter house 9II.

  • Finally we migh be able to get TRUE wireless speakers (ie no audio wires AND no power wires). I wonder how long before that’s commercial reality (and I’m not talking about 400 watt speakers — just comfortable 10 watts or so for home use with no wires — I’m not an audio freak :-) )

  • Rehashing Tesla’s experiments from a hundred years ago. Let me know when it is commercialized… it won’t be until they have figured out how to charge people for the transmission to their devices. Tesla of course envisioned free power for the masses; “…he was almost entirely unconcerned with material wealth. He ripped up a Westinghouse contract that would have made him the world’s first billionaire, in part because of the implications it would have on his future vision of free power…” (source: Wikipedia)

    I see these “Intel” articles all over the net and they are not even acknowledging Tesla. The title should read “Intel showcases Tesla’s wireless power”

    THE TRANSMISSION OF ELECTRICAL ENERGY WITHOUT WIRES
    Nikola Tesla, Electrical World and Engineer, March 5, 1904

    Yes… 104 years ago, thank you Mr. Tesla.

  • This sounds like HAARP and the phisiological action of ELF on the brain. This is being researched by Westinghouse, Penn State
    the Marines, the Army and ARL Boyers and ARL Penn State. We have
    to reduce population by 66% and this is a nice way to go. I was
    in the Centre County Jail without a warrant and I was between two plates for 5 days and they did stop my heart twice, but it was just a test of the Navy equipment. I think the predicting is that the prison population will double and they will just turn them off as less than suitable for further life.

    I have a cochlear implant powered by this technology that functions as a transceiver, so they did some interesting tests.
    I protested Paternoism at Penn State…meaning you have a party instead of beating up your guests.
