  1. Avataaar/Circle Created with python_avatars Simon Upton-Millard says:

    They just bring out 500w as Nvidia release GPUs that need 1000w power supply so don't see a gaming PC running wireless, monitor all ready have a display cable so power cable is no worries, could see the tech been built into a desk pad maybe with 100w max to charge Phone, Tablet, keyboard, mouse, headset, controller and maybe run & charge a thin and light laptop (mine has a 65w charger) maybe charging a Nintendo Switch and a steamdeck? But in use they would be well out of range but some gaming laptops already have 330w power bricks and 180w is normal so nah not going to be wireless, maybe a market to reduce charger cable clutter if its cheap but nothing more

  2. Avataaar/Circle Created with python_avatars MartelDuV says:

    I went and checked because the power brick for my laptop charger looks about the same size. It's marked as 90 watts.

  3. Avataaar/Circle Created with python_avatars Acool18 says:

    500VA (50mm over TX-Coil) over Wireless… Good luck with your min. 5kVA Transmitter

  4. Avataaar/Circle Created with python_avatars MartelDuV says:

    Oh man, thinking about my gaming rig with wireless… wants me to yerk off my cable… wait what?

  5. Avataaar/Circle Created with python_avatars Some Guy says:

    Quite honestly what is the advantage over Qi? Just slap a Qi coil on the band of a wireless headset, bottom of wireless mouse and keyboard etc… and put the charging coil in the RGB desk mat powered by USB and that's all using today's tech.

    Monitor and PC are rarely moved so who cares, just do proper cable management and it won't be noticeable.

  6. Avataaar/Circle Created with python_avatars Honu Moorea says:

    They got 97% invested in their bullshit marketing, 2% in pizzas and coca cola… And 1% in research.

  7. Avataaar/Circle Created with python_avatars Honu Moorea says:

    Most pc gamers play with mouse keyboard and cordless is good even if never bought them… cause they are more expensive and need more power.
    There already are powering mats and cordless mat, the mouse still have a battery inside, it just charge with induction.

  8. Avataaar/Circle Created with python_avatars Honu Moorea says:

    Naaa.. No cord on the table, the ground is coiled which send power to the table which send power to it surface… Well… in their heads.

  9. Avataaar/Circle Created with python_avatars Honu Moorea says:

    Powering the laptop is easier then the monitor.

  10. Avataaar/Circle Created with python_avatars Honu Moorea says:

    You can see in their attitude that it's bullshit, they do not believe in their shit.

  11. Avataaar/Circle Created with python_avatars Sea_Gull_89 says:

    I'm just imagening their ads launching with intentional typos, like "the crazy charger!! it's not just for quazy gamers!"

  12. Avataaar/Circle Created with python_avatars Honu Moorea says:

    We need to go to the efficiency road, not practicality…

  13. Avataaar/Circle Created with python_avatars W Burger says:

    Soon they will call solar power as "wireless power charging"!

  14. Avataaar/Circle Created with python_avatars Phil Richards says:

    The 0.3% efficiency was under a heading for "prior technology" – so I suspect it is the one on the graph that was the big V shape.

  15. Avataaar/Circle Created with python_avatars Paul Greeve says:

    You cana break the laws of fish-sticks captain!

  16. Avataaar/Circle Created with python_avatars CaptainBoring says:

    Why they just don't mount array of Qi chargers to the desk and only those which would have device over them would be transmitting power. Of course it would be only for charging mouse, keyboard or phone, but it would be nice not having to recharge these things.

  17. Avataaar/Circle Created with python_avatars rtsp says:

    Wifi and other wireless communication dead.

  18. Avataaar/Circle Created with python_avatars Mufeed Al-Hashim says:

    Did they wirelessly connect HDMI or DisplayPort cable to the monitor?

  19. Avataaar/Circle Created with python_avatars ats89117 says:

    LOL, It's turtles all the way down!

  20. Avataaar/Circle Created with python_avatars Long John says:

    Go look at the FCC rules for a 500W 15MHz transmitter and safe operating distance from the antenna ….. According to the FCC an amateur 20M station (14 MHz) operating at 500W you need to be 3.4 meters away from the antenna at a minimum ….. Which means you cannot have the antenna anywhere in the average sized room without subjecting humans and pets to dangerous levels of RF power. This also assumes a 0 db gain antenna (omni-directional). If you are using a gain antenna such as forming it into a beam or making it directional the the safe distance increases to 4.8M for a 3 db gain, 6.8M for a 6 db gain, etc.

    There is no way you are going to develop 500W of power at 15 MHz and get it past the FCC …. If you drop it to 100W you'd still need a 1.5M safe operating distance so you'd be lucky to get 5W at 15 MHz approved for something sitting under your desk …. And that doesn't even take into account RFI problems if you don't have a clean Sine wave and are radiating harmonics and perhaps jamming your neighbor's garage door opener ……
