eCoupled technology is taking wireless power to a new level of simplicity. By removing the last restraint of the power cord, eCoupled wireless power will finally allow the lifestyle of freedom you've always dreamed of. Working with industry leading partners to bring the technology into your hands, eCoupled is leading the charge towards a true wireless future. Learn about wireless power, the Wireless Power Consortium, and the new power standard (Qi.) The wireless power revolution is closer than you think.
A lot less wiring - copper prices to drop?
I really do not understand how power is supposed to be transmitted wirelessly.
What are the American Companies that are producing these devices and developing these techs, that we can invest in?
I really do not understand how power is supposed to be transmitted wirelessly.They are either using 'fields' or 'waves'
- Waves would use frequencies of several hundred MHz up through 2 or 3 GHz
- Fields would be using frequencies on the order of 100 kHz to 1 MHz
The difference is: the distance of 'effectiveness', with a 'wave' having greater distance capability (think: living in a microwave oven) of feet to yards.
e-Couple appears to need to use some surface. I’d assume devices would have contacts on the outside, and using some sort of grid on a flat surface, the electronics attached (and plugged in somewhere....) would detect how much and how long of a charge it needs and deliver it.
That’s just my best guess, after viewing the Youtube.
A wave would power something like a fridge, while a field would be for an electric shaver?
Just trying to compare things.
The ‘power line leakage’ nuts (think: eco-nuts) are going to have a field-day with this one ...
It was used primarily for communication. With a modified morse code.
Some smart people figured out that energy was being transfered, and worked on that angle, instead of the comms.
Does that help?

Diastance; the biggest factor has to do with distance -
Think: how far away does a bar magnet have to be away from something before it doesn’t pull anymore ...
A ‘wave’ has no distance limitation, not necessarily a power limit ...
and a bunch of other guys made spark gap work. Power was transmitted from one place to another without wires.Newsflash: We are doing this (to a lower power level) RIGHT NOW - it's called broadcast TV and radio.
NARROW the beam up enough (think short wavelength microwaves) and you could light up a light bulb a mile away ...
Yes, that does clear it up a little bit.
There are inductor based power systems all over now. My electric toothbrush has one. The Palm Pre has an option for it. This isn’t going to be powered across any distance, it’ll have to be very close and mostly be in contact with the device.
I think that does it. Now I guess I should watch the video.
The surface must be “enabled” and you device must be as well. Basically, an electromagnetic field is created in a particular spot on the surface. Your device generates current from this field.
It’s no different in concept than the charger for Sonicare devices. There is no connection. It’s a docking station that uses induction to transfer power.
Technically, it is wireless. My Sonicare has no wires to attach for charging. But, it’s not exactly “freedom”. I think it would be most usefull for desks. It would be nice to not have power cords for my laptops, monitors, etc.

Truly revolutionary ...
“NARROW the beam up enough (think short wavelength microwaves) and you could light up a light bulb a mile away ...”
Google tesla and colorado springs and wireless power. :)
He claimed to light up a string of bulbs without directed waves. He was using the earth as a common ground to transmit high frequency electrostatic waves.
“TWO HALVES of a transformer “
That was more concise and highly accurate on every level.
The grumpy old bastard thing isn't personally aimed at you. It's just my stellar personality. GRIN!

And, of course, they might be using an off-line ‘switcher’ design with a frequency of 100 kHz (or more) and using ferrites to make everything lighter and efficient ...
