#3Think I might let a different set of early adopters try this one out before I put one in my bedroom to charge my iPad. It may just be ignorance (knowing just about nothing when it comes to acoustics) on my part, but I'm way more afraid of this than inductive wireless charging.

#4this comment is a bit OT.
i wish i could see more founders who are ugly and short (either male or female), in the good books of VCs and SV, gives more faith in the ecosystem.

#6Both of those Examples involve short exposure. That doesn't necessarily mean long exposure is OK. You would not, I hope, conclude for instance that an X-Ray based system is safe because dentists X-Ray people as part of an annual check up.
I expect it to turn out safe, but I'd want to see some studies first.
Also, I'd like to see studies on what affect it has on pets. Will it also be inaudible to dogs? If not, that needs to be documented so that dog owners won't unknowing torture their pets.

The frequency range they list in examples for applications are from 40kHz to 110kHz. This actually does overlap with the hearing ranges of dogs and cats somewhat. Wiki lists the dog hearing range from 40Hz to 60kHz and the cat range from 55Hz to 79kHz.
Humans should be safe though since a common number for the high-end of human hearing is 20kHz.

#8> Mr. Nolan said Ms. Perry had shown that chain stores and some “quick-service restaurants” were eager to integrate a wireless charger into their plans. She “had addressed all these key risks and got them nailed down early,” he said.
To me, it's not surprising that folks would be excited by the concept of wireless charging, just as you could easily find plenty of people who would tell you they'd buy a Back to the Future-style hover board if you could actually build it.
The big question is whether the technology is real and commercially viable. One physicist who has worked on wireless charging applications says he reviewed uBeam's patent applications and ran the numbers. His conclusion: it isn't[3].
Who is correct?

Re: Audacious Plan to Make Electricity as Easy as WiFi
#9That's got to be a pretty loud noise to be able to transfer enough power to a device at a distance to be significant. Can long term exposure to loud ultrasonic noises damage your hearing even if you can't "hear" them somewhat like the way IR light can damage your eyes even though you can't see it? Think I might let a different set of early adopters try this one out before I put one in my bedroom to charge my iPad. It…
