    Waves hold energy right?
    Is it possible to recharge my cell phone wirelessly through some sort of electromagnetic/gamma/UV/etc ray?

    Yes it is possible, and they are working on the technology right now.

    One current form of the technology that is currently being used is an RFID tag. A radio frequency identification chip that uses a particular wavelength of EMR and converts it to electricity to power itself for a second and send a signal back; for purposes such as tracking. For now, it can only recharge itself if its within a short range of the transmitter, >50 feet I think.

    You can also convert other forms of electromagnetic radiation to energy, but its still being worked on. Right now it would very bad if you were to be beamed some energy wave (other than radio or light) at you; but people have talked about it being used to transmit energy from the moon the the earth wirelessly; but to an absorbing facility where people aren't present.

    RFID technology only transmits very small amounts of energy at this time, but they are working on making it more powerful with a higher range for purposes like the one you described.

    But you know, you can always just plug in a portable solar panel to your phone to get some EMR!

    shine a lazer at a photoelectric generator and voila!

    You'll need to capture the energy, and then turn it into something that's useable. Also, the energy you would be able to capture would be so small it could take a while (depending on the type of wave) some electromagnetic waves can transfer alot of energy in a compact bundle. Your phone's light cells would have to be facing directly towards the light source ect.
    It's possible with the right equipment... but not realy very economical (my mind went blank there... I can't think of the right word that one's good enough though)

    lol, thx. I was worried about you getting to it first.

    Small solar panels like that are known as trickle power sources, or trickle panels....since it takes a long time to charge things like a cell phone or MP3 player.

    I have a friend that took his garden lights out, and stripped the solar pannels off just for fun. He was surprized. With enough of them, he was able to charge a pretty good size battery in about three days.
