Is it really "game-changing?" You can only use it for low power devices which could also be powered by a small lithium battery for a year. So preventing me from having to change a battery once a year is now game changing?

Maybe preventing you from having to pay for the manufacture of a small lithium battery is a step towards game changing?

  Only if this is cheaper, and you have room for a big antenna.

In a world where you have 100s of such devices, absolutely.

  And not only that, some devices are very hard to reach once they are integrated and their mailfunctioning due to failed batteries would be a show-stopper if the expected lifetime of the device is a multiple of the expected battery life.

    I guess we could beam power to them, using a strongly directional signal. Boosting Wi-Fi power to charge devices seems like absolutely mind-boggling waste.

      For that you'd need to know where they are.

        Phased array antenna and some feedback system, so that I can track the device? Anyway, you obviously have something particular in mind; could you give an example of a device, for which an omnidirectional wireless solution would make sense, factoring in inefficiencies? The only similar-sounding problem I'm familiar with are long-lived devices mounted underwater or otherwise mounted inside a structure. I've seen wireless power via inductive coupling being used to power such devices, because both the device and battery pack can be sealed off from the environment during manufacturing, and replacing the latter doesn't require any disassembly.

        Let's see: where is my 'x' (tools, keys, shoes, glasses etc), data acquisition (temp in any room in the house for instance), various scada applications that now require a large amount of wiring (alarm systems for instance) and so on. It'd be quite the wave of new technology. Imagine, nothing would ever be 'lost' again once you knew it was yours before. The possibilities for use and abuse are just about endless.

        Uh, ok. I see my imagination isn't good today; now that I see them, those examples are pretty obvious. Though I admit I was thinking about devices that eat much more power. As for "where is my 'x'", I'm actually surprised this isn't a solved problem yet, but I attribute it to the fact that we're still in the early IoT era, when every company wants to lock us in into their bullshit ecosystem of beacons and beacon apps. Though maybe it's changing, now that (again) China is popping out cheap BLE tags.
