wireless power transfer
can anyone help me how do you wirelessly transfer power? what kind of modulation, transmitter and receive to use? thanks all!

i think laser can do it
Any electromagnetic wave could be used for energy transfer, with more or less efficiency.

Look into what are called "beam waveguides". Essentially you have two antennas arranged so there is very little spill over loss. You don't say how far or how much power you want to transfer but moving any significant distance without a transmission line is going to be difficult. In general you will experience loss increasing with the range squared (or more). That makes it impractical really quick.
I am not aware of anything that I would consider a really good solution for 'power" transfer.
What kind of data you are trying to transmit? Music, video or data? It is hard to tell you the answer because it is application dependent. If you want to transmit a high bit rate data, you may need to use higher frequency with high bit rate modulation.
hi first check this out my video, then what all the information you need tell me i will provide you.

You should have mentioned "thanks" to Marko, from http://4hv.org who's project was inspiration to you.
