UBeam wireless charging demonstration
- josephpmay 9y agoOn one hand, it's crazy that they pulled this off, of the other hand, I'm not sure if I see the practical applications of near-range wireless line-of-sight charging
- harshaw 9y agoNo idea about speed of charge. That's what the game is right now. I used to have a phone with wireless charging but it was way slower than using the wired smart charger (the one with the tech from Qualcomm)
- clarkcox3 9y agoBut if this was present in your office/classroom/car it wouldn't matter if it was slow, as long as it was fast enough to provide more power than you were using at a given time. I.e. It doesn't matter if it takes 5 hours to charge if you're around a source 8 or 9 hours a day.
- lewisl9029 9y agoExactly. I have 2 wireless (Qi) chargers at home (1 at my desk, and one near my bed) and 1 at my workplace. Sure, the speed is quite a bit slower than wired chargers (charges from 0-100 in a couple of hours when idle, instead of < 1 hour when using a quick charge wired charger), but it's completely effortless to keep my phone on a charger almost constantly, so it's always near 100% when I need to leave with it. And I still have the option to use the wired charger for when I really need that quick boost, but I personally haven't touched mine in years.
- erobbins 9y agoI'm still extremely skeptical about this. The inverse square law is a huge hurdle, power delivery rate has got to be minuscule. This isn't making a better charger, it's making better physics.
- 2bluesc 9y ago> power delivery rate has got to be minuscule Amazing that during the whole presentation the word "watt" was never mentioned to describe the power delivered and at what range.
- Xlythe 9y agoCould it be used to power wireless mice, keyboards, etc? Things that are generally low power but still require batteries every N months?
