Hello Friends I am a engg last year student and I want to make a project on witricty or on a wireless energy transfer to the enery to glow light. I have also seen the video of TED on witricty.

Can some body give me its Circuit Diagram and some explanation? Witricity powered: a witric one!

I dont understnad this
"the input current is modified from a sinusoidal into a rectangular or transient waveform" from Wiki-Wireless Energy Transfer
Could anyone elaborate on this statement in regular everyday speak, how it works and how to actually do it? Witricity powered: explain witric..

emm.
iwould like to make a project on witricity
that was the wireless energy transfer
and i do not knpw how to start it
anybody could give me some idea
or witricity circuit to share Witricity powered: explain witric..

Hi,

I want to power a 3 mm typical (common) infrared LED via wireless electric transfer using NORMAL INDUCTION (NOT RESONANCE).

- If I use approximately 1.5 cm diameter coil with at least 15 windings for both transmitter and receiver, how far can the two coils be before the light dims to only 70% of the maximum LED light luminosity (i just want to get an idea of the max range of induction energy transfer - seems hard to find on internet.)

- can i get smaller diameter and lesser windings for above case if the distance i want is less than 12 cm??

Hey,
For my physics coursework on wireless energy transfer I need to know wether microwaves obey the inverse square law? If not how do they travel, I basically only know that they are transverse waves. Does the intensity stay the same over distance in the same area? Witricity powered: go witric!

I know the basics of wireless energy transfer through magnetic resonance, and coupling and all that. I am planning/trying to power a light bulb (or anything, really...lol) from 2 feet away using this technology. I have gotten great resonance inside of the loop of copper wire, but never outside of it.

The action of an electrical transformer is the simplest instance of wireless energy transfer. The primary and secondary circuits of a transformer are electrically isolated from each other. The transfer of energy takes place by electromagnetic coupling through a process known as mutual induction. (An added benefit is the capability to step the primary voltage either up or down.) The electric toothbrush charger is an example of how this principle can be used. The main drawback to induction, however, is the short range.
