Vulnerabilities of this technology

This type of devices must only be used in RF bands compatible with biology (life) otherwise is a very dangerous technology. This type of device must have a password protection with charged device, if not acknowledge must not turn on.

Wireless Power

Wireless power is going to become one of the important technologies for better user experience in mobile devices and EV - primarily providing convenience. My question is whether it aligns to Intel core technologies and vision.

I think that's one of the major problems with wireless charging - actual efficiency. Seems like the industry groups don't want to give actual speed specs, but other pubs have tackled this problem: http://arstechnica.com/gadgets/2013/11/look-ma-no-wires-a-mini-review-of-googles-nexus-wireless-charger/

I think one of the main issues with mass adoption of wirless charging is that, at the moment, it's not terribly necessary. I don't have trouble plugging in my device normally, but don't want to purchase the infrastructure to do it wirelessly. Is wireless charging something that the public really wants?

"WiTricity power sources and capture devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field."

Setting asside the contradiction of terms: "large-distances" and "near-field", I would like to know how efficient this transfer is.  Ideally it would be 1:1, correct?  Or does resonance enable 1:x, where x > 1?  Now that would be something!  I've long held the belief that there is an element, or combination of elements, out there that when excited by an EM wave of some kind would actually produce more power than the excitation source provides.  An exercise of chemical engineering, I suppose, but is this it?

From Intel's statement:

"We have overwhelming feedback from end users that they are frustrated with dealing with all the different wires and power adapters for their devices..."

So my guess is that they dissagree with the low-profitability prospect. They're betting these people, and later...you, will pay a premium for something better in this mundane area.

" That's the reason why we have charging bowls..." I believe Intel's charging bowl also works based on the resonance technology...isn't it? Looks to me that Intel is promoting resonance technology based charging.

Power and charging for Intel?

Why suddenly Intel is interested in power and charging? This is look a low level task with minimal profit. What Intel will earn from this?

Two questions:

With implications for RFI and FCC issues, what frequency do they use?

What happens to the mag strip on a credit card if you stand too close?

I like high-power IR laser steering idea. It should have cockroach-killing capability too.
