Xiaomi Announces 'Mi Air Charge' Remote Wireless Charging Technology

It's been known for long time. But who wants to live in an apartment that is beaming at you constantly.
Multi-walled CNTs inlined directly between energy source and battery... can be used to accelerate electron flow(increasing current), in minor bursts that helps saturate a battery’s storage matrix more effectively. Essentially while traveling across the CNTs, electrons become weightless, and regain their mass with a minor bust of acceleration we see as a current increase when it reaches the other side. Quantumly Accelerated Electrons...
People will see that Apple once again will make this a thing.
If they didn’t invent something the never played it as if they did.
I am curious about how much power that unit draws for the 144 antennas and the built-in computer. Also, how much heat does that unit generate.
I remember when MacRumors was simply a community of Apple fans. It has nothing to do with being salty or defensive for Apple it's just like... why are you here?
I'm new to this group but have 50 years experience in RF EMI EMC including RF safety. Could not help but comment.
First, this is 'old news' and has been 'announced' by others looking to generate a marketing buzz -- the most recent prior to this being in 2017 or there abouts. No practical embodiment has ever been approved or marketed. Lots of reasons for this, of course. The main one is that unless many very difficult variables are engineered properly, this would be an incredibly dangerous device, especial in a residence. The product announcement claims to handle this without actually a sufficiently detailed technical discussion by the use of a maneuverable directional a tight beam that would automatically locate, lock on, and then target the device. And use low power pulses of RF to then charge the device. All well and good, except this is incredibly difficult and would still need a very serious safety evaluation since tight beams of RF even at low powers can easily exceed RF safety limits. One announcements states the design has been 'approved by the US FCC'. The FCC, which would have to review both the EMI aspects of such a product AND the RF safety aspects, has NOT approved ANY 'wireless charging at a distance' device. Period. Full Stop.
Even the induction contact charging stations that exist today for cell phones must meet FCC and safety requirements, and the closeness to the radiating device makes that application much less problematical this embidiment.
Good quality induction devices for cell charging must bear the FCC logo and at least one 3rd party safety agency such as UL, ETL or CSA in the US. Illegally imported units from China have no such indication on the product.
It is also illegal to make marketing statements claiming a product is FCC approved if it is not, by the way. A company that is already in the cell phone business should know this.
So, do not look for this anytime soon. Personally, I question the risk/benefits of such technology at a the power level of 70-100 watts required to operate the main station even if they overcame all of the issues.
And yes, Nikola Tesla invented the precursor concept for such a system at the turn of the last century. But, his investors, after advancing the equivalent of $4-5 Million refused to continue to fund since Marconi had just demonstrated his wireless communications equipment, and it was clear that even if they had wanted to continue to back him, it would have taken an immense amount of money. Tesla himself, as brilliant as he was (and the man was a genious!), had no clue as to the safety issues presented by such power at a distance systems as he was experimenting with contemplating using to transfer power around the globe. It also did not help that he had claimed to receive signals from the planet Mars using his technology, which further did not comfort anyone looking to invest.....

I'd have to imagine they'd have a way to not accept the charge forever. They already do this. It's how it's possible to have a phone charging all night and wake up at 99%. Happens to my watch often.
