Wireless electricity Definition and 13 Threads

A post, each which connected without a wire, is it possible in a brief future?

Folks, I am still thinking of the possible approach to solving a problem of having to run poles and power lines to transmit electricity from one point to the other. Can there be a way it could be done in that we can convert electric current into electro-magnetic waves that can be transmitted...

Hello , I am doing my M.Sc in wireless power transfer using resonant inductive coupling.I want to know what topics i should read and understand to master this research.

Hello, I would like to develop a testing method to detect window defroster grid failures. Rear windows has 12 heating wires painted to the glass and cca. 2% are faulty pieces. I tried to measure the resistance, current and voltage drop of good parts and compare results with those where was at...

Hey guys; I'm looking for info on the maximum power transfer using the magnetic induction method. The current through a coil, then catch the mag field with another coil idea. Mainly looking for high energy transfer methods, maybe some equations that describe it. A friend and i are playing...

What is the difference between magnetic resonance and magnetic induction when it comes to charging devices and other types of wireless electricity. I was doing some research on this but was not able to find a clear answer. If someone could help me with this that would be greatly appreciated...

http://www.ted.com/talks/eric_giler_demos_wireless_electricity.html In this video, I have two questions: 1) Why have a capacitor as part of the two circuits? Is it so no actual current flows around the coils, that's all I could come up with. 2) In the picture he shows of the two...

Homework Statement list 3 ways of wireless electricity transmission and how??Homework Equations The Attempt at a Solution i got nothing =.=

I'm trying to replicate MIT's "Witricity", but on a smaller scale. I have a coil connected to a function generator and then a second coil (with more loops than the first) connected to an LED. So I guess now I have a transformer. And the LED lights up when the coils are up to 10cm apart. I...

Making Self resonating coils for wireless electricity transfer ! How to do @@ Dear Friends , I would like to make the wireless electricity project as done by MIT team.i am bit confused about how to make the two different coils resonate at the same frequency ?? Please help me... Thanks...

I came across an interesting story today and thought I would share it here. http://www.fastcompany.com/magazine/132/brilliant.html" Neat stuff. Although I do wonder, even if they get it working and feasible for large-scale adoption, would there be any adverse health affects? (I...

Can someone tell us about the possible implementation and application of wireless electricity? I know there is a lot of interest in the topic and recently, I read that MIT made a successful experiment of transferring power wirelessly. If we can concentrate the beam of the transmitting element...

I read about quantum entanglement in an article about teleportation I read on the web. If two particles can be connected despite an enormous distance, in such a way that the properties of one can be transferred to another, even though no wire or string is linking them, can you use this...
