While not using the same Qi-like charging mechanism, the physics has been proven: https://www.disneyresearch.com/publication/quasistatic-cavity-resonance-for-ubiquitous-wireless-power-transfer/ https://www.disneyresearch.com/publication/quasistatic-cavit...
- harryh 9y agoWithout commenting on the viability of the method in that link one way or another, I will point out that the physics is described are completely different than what uBeam has said they are working on. uBeam has said they are wirelessly transmitting power via high frequency sound. This link describes a method that uses magnetic fields.
