At the present time there is no technology to do this, but the same was said 10 years ago about watches and now they can be charged using kinetic energy (well, strictly speaking it is not kinetic energy, but thats a scientific thing so I wont bother too much with the details) so I would guess that, given a few years, the technology will become available and practicle.

no i dont think so kinetic energy means motion, not technology
-
it can do, i don't know if we can do at the moment. but it's possible.

Chemical Energy Powers a Cell Phone not Kinetic Energy, But its could be possible, but the cell phone would be less mobile,
-
no problemo - just convert it first into elven magic so the kebler elves can bake a cookie the feed it to the energizer bunny then put those clippy things on his ears and you are set. If thats too much work most outdoor stores sell hand-crank generators that come with adaptors to fit most cell phones, have one for mine

A portable technology to [i]generate[/i] electricity through kinetic motion is call induction coils which is basically a metallic coil with a magnet moving through the middle. When the magnet moves through the coil, electricity is generated. That's how those shake flashlights work. A direct way to use kinetic energy is to store it in motion, such as a spinning thing. This is already done as a cheap, easily reliable battery. You basically set something spinning in a vacuum held up by magnets (just to reduce friction) and if you need more energy you slow down the spinning thing and when you want to charge it you speed it up. This has been tested in metro transport, and worked fairly successfully, but the charge is too small so they had to recharge the buses every few blocks.

holdong your phone up in sinlight will charge it

Directly? No. However, there are *many* ways to use kinetic energy to generate electricity. Ever see one of those flashlights that you shake to charge? A magnet, a coil of wire, and relative motion between the two generates an electrical pulse each time you shake it. Shake it enough and store each of those little pulses in a battery and Voila! Ever see a hand-crank generator? Same principle, only using rotary motion. Ever see a Hydroelectric dam? Same principle, only using the kinetic energy from rushing water. Ever see a portable generator? Same theory, only using the kinetic energy from the crankshaft of a gas engine. Ever see a nuclear power plant? The glowing bits heat water, turning it to steam, and the steam drives a turbine. How? Kinetic energy. And the turbine passes it's kinetic energy to an electrical generator that puts out... well, I think you know what they put out ;) Now, what do you propose to use as a source of kinetic energy?
