Wireless Energy : WiTricity (16)
Author: EnviroCitizen
WiTricity is an exciting company with an even more exciting idea. WiTricity was founded in 2007 in response to the invention of wireless electricity. That's right, electricity can now be transferred wirelessly! A team at the Massachusetts Institute of Technology (MIT) developed this wireless electric power transfer, and WiTricity is delivering it to consumers.
WiTricity has some big dreams. They dream of a future where cell phones recharge themselves without being plugged into a wall, making phone chargers obsolete! They illustrate the new living room of the not-so-distant future (they estimate within a year or so) where a large, flat screen television is mounted in the middle of the wall, and there are no wires dangling below it. EnviroCitizen.org is very excited about the possibilities they are proposing!
WiTricity is going to benefit the environment in many ways. For starters, their wireless electricity technology could help to commercialize electric hybrid vehicles. Instead of needing to plug a vehicle into a charging station, electric hybrid vehicle owners could simply stop near charging stations and wait without having to even get out of their cars. This simplified charging would make it easier for consumers to charge their electric hybrids more frequently, which would translate into smaller batteries, and thus, a reduced cost for the vehicle. Making it simpler to charge electric hybrids will also make them more appealing to the average consumer.
There are other environmental benefits to electric hybrid vehicles as well. Renewable energy systems, like solar photovoltaic cells or roof-mounted wind turbines, could be installed onto roofs without needing any physical connection between the solar panels or turbine and the electrical system!
If WiTricity's dreams become a reality, life in the United States as well as around the world will change drastically. Americans may one day enjoy a cordless, more energy efficient life. Consumer will no longer be "tied down"; you can drive your hybrid vehicle to your house at the end of the day, and the solar panels on your roof will power your hybrid vehicle without you needing to do anything further. Can you imagine what you would do with this kind of freedom?

Heres an idea..convert electrical energy into light energy then focus it like a laser over any distance onto a solar panel which converts it back to electrical energy again. et voilla!
Is wireless power transfer possible over long distance?
I have always been wondering about this.
How can i achieve magnetic resonance coupling to make wireless power transfer?
Im trying to make a simple inductive power transfer just to understand how it works.
I see some tutorial out there but they dont explain well, they just give a nin flexible recipe to create it, but dont explain why..
Can someone help me?
You can certianly make your own. I recomend tearing apart an old rechargeable tooth brush to see how it works. The key is to use AC, two wire coils of the proper resistance, and to use an iron core to boost efficiency.
HyperPhysics.info will have all the info you need to size your device.
A quick search for inductor and transformer gives these useful links:

with no core? you won’t get any appreciable amount of power transferred. 43 nH is very small.
If you wind the coils on top of each other, you may get some power at a very high frequency. But I doubt it.

Store product security,
the inserts that are detected at the door.
Add to your report information on building a practical unit.
A power stand to charge PDA’s, Cell phones, laptops,
rechargeable flashlights, remote controls for entertainment.
It would be a good system for all electric cars, they could
charge while on major highways, and use batteries else where.
Solar power could be sent from the moon to the earth via
microwaves, higher frequency inductive power.
Just some food for thought.
As a side note,
under common useage, avoid resonance in inductive circuits,
because induced voltages are not just dependent on turn ratios,
but on the ‘Q’ of the coils. That is how a Tesla Coil gets high
voltage / frequency.
help with writing a report about inductive power transfer(wireless power transfer)?
HI,
Im currently trying to write a report on a project that I have been working on but am running out of topics to write about. The projects on inductive power transfer.
The topics i have so far are History, inductive power transfer(how it works), Transformers, Magnetic fields, transmitter and receiver coils, assembly of coils, resonance, Applications, electromagnetic shielding, software. I have only written about a page or two on each and so far I only have around 20pages, I need about 45pages.
Has anyone any ideas for new topics that I could/should add in? or does anyone know any good websites or papers/books that could help me expand on what i already have.
Thanks,
RD.
What is the optimum frequency (or the equation) needed for wireless power transfer using 2 inductors?
i’m thinking of building a circuit with 2 inductors (primary and secondary coils) to transfer voltage from the primary to the secondary. my output voltage would be 12V, inductance 43nH.
we just order 47mH inductor do yoiu think this should be enough?
go digital
How do you define the best possible circuit for RF wireless power transfer in use for embedded devices?
I am working on a project you can check on http://wirelesspowertransfer.blogspot.com/ And I wish to have any relevant information regarding my subject. Thank you
