I am amazed that the people in the uBeam video demonstrating the prototypes do not appear to be wearing ear protection. This is prototype equipment - people should have protection.
When you look at the surveys of research into 60Khz exposure, there is very little actual research data so no-one can actually say what levels are safe. Basically, it is probably impossible to find workers that have been exposed to constantly high levels of 60Khz sound so there is no hearing loss data.
As a side note, am I the only one that does not have such a need for charging my phone everywhere? I plug my phone in the charger at home and sometimes at work. it lasts at least a day, so as long as I charge it at home once a day I never have to charge it anywhere else. There seems to be this odd craze about being able to charge on the go.
My Motorola X Force last a good 3 days on the one charge. Granted, I'm not playing games or watching video 24/7, but even then it's supposed to last a whole day.
Now, since there are potentially way over hundreds of thousands of bats in a large cave, you can maybe do some damage with a portable transmitter targeting all of them individually...
I'm not sure a 2KW airport bird scarer with a range of 4 meters would be all that useful.
My cheapo ZTE used to last 10 to 14 days when it was new. It's coming up to 3 years old now and I'm worrying I might have to get a new battery soon because it's down to only 5 days.
At the upper end of the spectrum, the governments of Israel and the United States of America are developing stink bombs for use by their law enforcement agencies and militaries as riot control and area denial weapons. Using stink bombs for these purposes has advantages over traditional riot control agents: unlike pepper spray and tear gas, stink bombs are believed not to be dangerous, and they are effective at low concentrations.

Regarding ultrasound as crowd control, I might have a story about pacifying a drugged-out neighbor turning up his subwoofer loud at 4am, every night/morning. It's incredible what a small Bluetooth speaker and an Android signal generator can do. Unfortunately it's not related to the topic, possibly not legal and likely never happened...
A few years ago, someone had come up with a "crowd control beam" that caused anyone to be hit with it to instantly loose control of their bowels. I don't know what became of it, but talk about the most effective crowd control method ever!

It was a VLF inaudible frequency which vibrated tuned to the average dimensions of your gut with embedded almost audible thumps as well. If I remember correctly, saw it in a documentary quite some time ago.

Yes, it was something like that. I'm not finding much on Google, but at least I know someone else has heard of it too! Just a matter of finding the right keywords...

This video blogger's starting assumptions about uBeam are all incorrect. This person knows nothing about the company or our technology."
Missing the whole point that you don't need to.know anything about either to demonstrate its bullshittyness
