Disney Research and wireless power transfer.

https://www.disneyresearch.com/publication/quasistatic-cavity-resonance-for-ubiquitous-wireless-power-transfer/

"An experimental demonstration shows that a 54 m3 QSCR room can deliver power to small coil receivers in nearly any position with 40% to 95% efficiency. Finally, a detailed safety analysis shows that up to 1900 watts can be transmitted to a coil receiver enabling safe and ubiquitous wireless power."
Not ultrasound and the entire room has to be designed with this in mind.
Quote
We introduce quasistatic cavity resonance (QSCR), which can enable purpose-built structures, such as cabinets, rooms, and warehouses, to generate quasistatic magnetic fields that safely deliver kilowatts of power to mobile receivers contained nearly anywhere within.

I think that's an appropriate level of tradeoff that most of us here are expecting when they say "not impossible, but highly impractical".

Yep, I'm kinda aware that it's not ultrasound - but your second statement is exactly what I posted the link. There are always tradeoffs in safety, efficiency, cost, charge rate, and practicality with wireless power - this one loses on practicality and maybe cost. So even when safe (though I'd want to dig into that more), somewhat efficient, and with a solid charge rate, there's no route to a large scale commercial product with this. How well does that bode for any other at-distance wireless solution? Disney apparently see that, which is why they published it, and why no-one else, anywhere, is going nuts over it.

I commend them for the detail in which they presented their work, they did a good job.

If the physics don't work, then try a different engineer.
http://www.startuphire.com/job/mems-modelling-and-simulation-engineer-santa-monica-ca-ubeam-402303

WTF:?:

"Working Conditions

 Must have the ability to stand or sit for an extended period of time
 May require lifting of up to 50 or more lbs.
 Work may include use of chemicals such as solvents and/or epoxies, and others
 The current position is located in Santa Monica but uBeam reserves the right to require work in other locations and/or relocation from Santa Monica
"

Is it normal to put this in a job ad?

Nothing jumps out as odd for a US job posting. The standing and lifting parts are probably related to if disability accommodations will be needed. I know that "Can you lift more than 50 lbs.?" is a pretty standard question in applications.

But uBeam doesn't even meet basic theory if atmospheric absorption reaches 99% after a few meters of air.  uBeam is flat out impossible to get above 1% efficiency at any usable distance.

What you're talking about where something is theoretically possible but totally impractical is Energous (WATT stock).  Energous uses RF to send power which is fine so long as you're willing to run a microwave oven with the doors open and you don't mind accidentally exploding someone's eye.

The only solution that works at a distance is resonance inductance charging.  That's the only technology that can pass through a solid wood table without losing power.

Surely the company is now all but dead?
There doesn't seem to be anyone there doing the technical hard yards, practically every executive and technical head is gone.
And they can't seem to hire anyone new.
Just a slow bleed until the remaining money runs out?
No one would be dumb enough to invest again given almost every high profile person has left.

"Execution of uBeam Operations" sounds remarkably honest.

Still going, and I'd guess in the midst of a fundraising round just now. Don't be surprised to see another substantial investment round announced in the next two months. That demo will be compelling for those who don't get that the laws of physics don't change over time, and that Moore's Law doesn't apply here. Remember this is a VC world that put $120m into a juicer, and Energous (WATT) has a market cap of $300m. I'd say it's a coin toss as to whether this happens or not, but there's a ton of money out there looking for a home right now, and someone might be dumb enough to use WATT as the benchmark, which would be ironic given the similarities there.

I just told them, that I hope they will get brain cancer from their own product.
And I'm dead serious.
They remind me of children, trying to charge phones with loaded machine guns or lasers that can blind you, waving some papers, that none of those things can kill you, because we did a test for 0.01s and the machine gun did not hurt anyone. Trying to install it in public places.

That looks to have been uBeam that trademarked it, so not an issue.

However, Energous creating a ton of patents in acoustic wireless power transfer might be...

Lol!
What a laundry list.
Perhaps they figure it might be cheaper to hire ONE person to: Invent (oops, Meredith already did the hard part), Design, Prototype, Do the industrial design, Develop for production.
A whole team clearly costs too much at this stage!

If I was an investor this would be a frightening advertisement.

Buy why? look how much fun they seem to be having. What with so many out of the BOX thinkers on the wall to inspire everyone not to accept commonly held scientific dogma.

Isn't it nearer $60m and 6 years. Their steerable phased flat panel is becoming a bit parabolic.

Sorry, I guess I missed that last phase of phunding (sic).

It still looks like a phased array, done in a hexagonal tiles of about 14 x 14 transducers.

I may be mistaken but they appear to have cunningly airbrushed/defocused the transducer stack for some reason. Or maybe it's the air in front of the transducers going into non-linearity and refracting the light.  :-DD

Meantime, there appears to be a rubber brick attached to the phone, approximately six times the volume of the phone, and probably six times the mass, possibly protecting it from disintegration from the ultrasonic beam. It looks like poor Meredith's nail varnish is suffering delamination already.
