    I understand this is a small scale, but it has possibilities for small applications

    I wonder if they mention Tesla in their patent. Since He, back in the 1890-1910, pioneered wireless energy trasmittance but never got the support to pursue it.

    And it's taken us 100 years to catch back up.
    He made solar cells back then also, and methods to extract electricity from the ionisphere and from the earth itself as well as a death ray which we are now realizing the potential in the SDI program and HAARP. BTW Marconi used 17 of Tesla's patents to "invent" the radio, LOL marconi was a hack.

    Tesla was and is the smartest man ever on the earth.

    I think you're probably right on that one. He never got credit for most of his work.

    But, was he a man? [dunno] [alien]

    Optical power transmission? What do they do, shoot laser beams to the receivers? Until someone rediscovers Tesla's methods any wireless power transmission system has enormous losses. Something smells fishy about this.

    This may be possible :rolleyes: but having worked around HV transission yards I would not want to be subject to the flux created in transmitting the power.

    That is exactly what they do. IR lasers.

    I saw a "test" on this performed out in the desert on some (discovery?)channel...It was interesting!
    It worked too.

    Just don't step between the transmitter and receiver! ;)

    Well, you see, that's the neat bit. They have a cutoff built in to shut down the laser if the beam is interrupted and the receiver will provide power from an internal backup battery until the beam is no longer obstructed.

    Slick enough idea, but it incurs an energy loss over and above direct wired power connections between source and load.

    What application is this currently being used in? Can you link to a credible source or are you setting up to shoot us fish in a barrel again?

    Link from the manufacturer

    Sure, I read about it here, on their own website.

    From the website:
    "Our High Power solution is designed to provide direct power, or to re-charge lithium ion batteries, for high power devices that run primarily off of a power cord or use power cords to recharge lithium ion battery. This solution delivers 10 watts of power from less than 1 meter up to 30 meters. The major benefits are Installation Cost, Freedom of Product Placement and Aesthetics. Examples include: Digital photo frames, laptops, laptop accessories, flat panel TV’s and any other device that requires high power to either directly charge or rapidly recharge a lithium ion battery with a high power load. ----------."

    10 watts is not much. I would not be surprised that it'll run the items named, but it ain't gonna do the dishes nor run the sound system.

    The website also alludes to never needing batteries, but that is patently untrue, it also says if the beam is interrupted, the powered device shifts to battery. Also, it is completely unclear to me how the beam interruption is detected and the shutdown order transmitted. Also there is not mention of power saving, and I suspect that there is HUGE inefficiency converting from 60 cycle to infrared. I'd be delighted to find otherwise.

    Overall it may be the wave of the future, but for now, I'll dangle cords.

    They use sound to vibrate light waves which in turn vibrates into a reciver, thus laser listening devices. So it's not far fetched to make electricty move light then make the light move electricity on the other end.

    Waves are waves, be them light or sound or magnetic or radio. The same physics applies.

    Wireless transfer has been achieved...so far best distance is about 15 meters...through walls. High frequency electricity....
