Wireless power transmission

A wireless power transmission system based on evanescent waves and resonance. The system shown in this video was build by Cornell College students Lucas Jorgensen and Adam Culberson using copper tubing and a few plastic drums. Their paper shows how you could build a similar system. You can find out how at http://www.cornellcollege.edu/physics/courses/phy312/Student-Projects/Magneti...

simple transformer primery and secondry

@salimkhan007 Hi - there are subtle differences between this system and a simple transformer. You should try a Google search on "MIT Wireless Power Transmission" to find out about the details of this system. This system is neither a radio nor a simple transformer, but something in between. It produces an evanescent wave that decays exponentially in space and resonantly couples the two coils. My students were able to demonstrate both the resonance and exponential decay.

man, you all don't appreciate how cool this is.

Magnetic loop antennas have been around for centuries.

Zillions of radio sets have been built with ferrite antennas.

(You could make your design smaller by using ferrite rods).

Yawn. It's sooo old. Yaaawwnnn.
