At the Three Rivers Venture Fair in Pittsburgh, WoW! Power demonstrated RF power distribution to consumer electronics.

Everything on the table – from Xmas ornaments to battery rechargers to wireless keyboards – receives its power from the RF antenna on the left.

Power transmission drops with distance squared, so the challenge is to find the killer apps for short distances, where wires are a hassle. Wireless desktop devices and Xmas tree ornaments are good examples…

I suggested that they should discreetly recharge JimmyJane devices in the bedroom.

  1. The dilemmas of modern technology and abundance!

  2. heh heh – i didn’t really need to look up JJ, having never heard the name before, but did anyway – poorly timed to coincide with one of the library patrons here peering over the counter…. oops!

  3. Full disclosure time…is DFJ funding JJ!? LOL

  4. That sure would be fun…. but we’d be clueless… 😉

  5. Steve, I always learn something new here! 🙂

  6. I’ve been waiting for this technology to become mainstream ever since reading an article in Popular Science at age 10 — about a plane that could be powered wirelessly by microwave energy. (Wouldn’t want to get in the way of that beam. 🙂 )

    This is cool technology – reminds me of Splashpower, the power pad that charges devices placed on top of them (something my desk desperately needs).

  7. I only wonder about how healthy this is… what sort of frequency are we talking here?

  8. That’s gotta be efficient

  9. Well, the real trick is getting consumer electronics manufacturers to put in the RF power recievers in thier devices… without adding much to the bulk.

    Looking for a killer app?

    Imagine a world in which I only need two chargers, one at home and one at my office. When I walk through the door, I set my briefcase down next to the charging station, and my devices (phone, camera, laptop, bluetooth headset, et cetera) are always at full charge. Without messing with a single plug.

    Major obstacle is the power recievers need to be built into the devices at the factory, hard to add them later.

  10. At some point all this wireless stuff will be found to ruin our health on a subtle level (studies already completed on cell phones) that takes decades to morph into observable phenomenon… just like the thousands of chemicals we ingest (like the neurotoxins flouride and teflon) which have eventually created alzheimers and many other ‘mystery’ diseases since going off organic foods for the first time in human history (story of the 20th century). The big picture tells the story best – slower adoption of technology is better.

    That being said, the photo is very cool though! Nice idea, just keep it away from me!

    So stick with batteries for the JJ stuff 😉

  11. Oh come now Victor, all these unintended health consequences just push the envelope of technology even faster!

    For instance, many of the early molecular manufacturing techniques are being made to build biomedical devices and therapeutics. The lab I work in, and many others around it, are pushing the nanoscale boundaries to come up with ways of diagnosing and treating cancers. The techniques will move into areas with lower profit margins, and end up in consumer goods and most likely make *someone* sick. Then we will have to come up with new technological solutions to fix them! (cycle repeats) Then I will have even cooler consumer electronics!

    Perhaps the underlying driver to the Singularity?

  12. Also, all these unintended health consequences increase the mutation rate of DNA, so we’ll evolve faster (into X-Men).

  13. What frequency do you suppose it runs at? it seems like a lot of RF pollution could be generated here, especially if your house is up on a hill!
