Wireless power system

[Bartman39]

Well it seems Intel has figured it out...

"The trick with wireless power is not can you do it; it's can you do it safely and efficiently,"

There was a DT article quite a while ago with MIT students showing off this thing. Intel took it on from there and improved upon it.

The concepts are not new but the problem is extending the range and power level without losing efficiency.

whats an "elective" field?

Wasn't the efficiency rating of these things based on distance, and the max distance 40 ft?

 

[KIAman]

Wireless anything efficiency is always based on distance. At a distance from the poles, magnetic field drops off at inverse cubed distance. That's worse than gravity, which always follow inverse square.

It's a good thing we can make very powerful magnetic fields.

You can transmit power wirelessly with Microwaves as well.

Nichola Tesla has patented his device for wireless transmission of electricity several years ago.

It was a good idea. I have all his patents in print, they are a good read.
If only he hadn't tried to make the next step of wireless power the shooting down of enemy planes. Got him the reputation of a crackpot.

Still the government did seize his work upon his death, hmm maybe he was on to something

Not sure I understand this quote:

"So what we are doing is transmitting energy using the magnetic field not the electric field."

I'm thinking that this has to be electromagnetic waves that're being used here.

It'd be interesting to know just how far the transmitter of this power was located from the receiver (and what their antennaa looked like).

I wonder if they're using some sort of transformer effect where the devices have to be in very close proximity...

Planes are generally made of metal, and IIRC most of the systems are insulated on modern Fighters, Even a lightning bolt probably wouldn't do much. A missile or nicely aimed railgun would be much more efficient, and in the case of the railgun, cost efficient.

They are using resonate induction but the problems (from what I've been reading) deal with the power and computing needed to calibrate the resonating circuit in real time. Intel, most likely, developed a low power high speed, dedicated resonating induction circuit that does not bleed disproportional amount of power it's attempting to transmit.
