I did read this arcticle too. Still a few obstacles to overcome. I guess one of the biggest issue has to do with safety. There is a minimum safe distance you need to be away from that transmitter.

They also have that for Ubiquiti APs.
Well, seems the engineers at Disney have found a way to do wireless charging and power.

Seems legit, but 1.9kw @ 1.3Mhz in an aluminum faraday cage sounds a bit microwavish to me, lol.
and 1.9kw input to get a few low power devices to charge? inefficient.
Just laymen observation, of course, and I can light a fluorescent tube with a 4W CB radio by placing the tube near the antenna, but it's not a great device by any means.
Hope there aren't anyone using the copper poles for other endeavors lest they get bitten by the RF bug.

I have 3 UAP-AC-PRO access points dotted around the house, including in my bedroom. I'm not worried about that. Their higher power and 24GHz gear, yep, wouldn't want to live too close to that.
As for the 1.9kW wireless charging experience mentioned by the OP, no way I'd touch it let alone come too close to it. It's something you only do once. RF burns aren't nice.
Here's an example from a 50kW AM transmitter:
I think the link between leukemia and HV lines has been debunked.
From USSR times around here I remember many public safety regulations which
were instantly demolished in '91 because stood in the way making profit...
When I started messing with electric stuff dad (former pro E tech) warned me - in the military they had only one young guy completely bald - it was radio technician
Also it is scientifically proven fact that with nearby high voltage powerlines child leukemia rates spike.
However they were puzzled why rates do not vary as square of distance (mag. field), but are linear instead.
IMHO what was not taken into account in this research - powerlines often act as wideband RF noise source.
Here's an example from a 50kW AM transmitter:
As someone has already pointed out the living near HV power lines does not correlate to higher rates of cancer.
Why use a pole? Can't you just build the cage and inside the cage make part of the ceiling a separate conductor with the modulated voltage? Moves the concentrated part of the electric field out of the way.

Says who? Authors of some other special "debunking study"? In true science noone has final truth. Id say subject is open to discussion as any other. When subject is suddenly "closed" or "debunked" usually there is some "greater interest" at play.
I did actual environmental survey when looking for new house. First found suitable place located about 800m from powerlines. But these were two of them located in V shaped manner surrounding property. Recorded general background level about ~80nT of 50Hz AC magnetic field varying quite logically in relation to lines. This was same as in some apartment with totally incompetent electrical installation (lighting phase/neutral in different wires on opposite sides of room). In average apartment with competent install level is 2nT or less. To put things in perspective ~80nT is usually recorded at 50cm distance from working high power electrical appliance (oven, heater etc).
Would you live and raise children while basically sitting on top of high power heater all the time? Or hassle with nasty 50Hz background in lab just looking for any conducting object to chew on? Not to mention wideband RF noise flood...
Honestly, try to use the "scientific method" a little more in your thinking.
