Read this- magnetic fields do NOT bend the path of a light wave. You may be
confusing the use of bending magnets on synchrotron radiation, resulting in
light, but that is an entirely different matter. There, the energetic particles
(which are not photons) have their paths bent and emit photons as a result.

Mobile phones draw next to nothing while you are not talking over them. The
limit to battery life is not only the phone's draw, but also the fact that most
NiMH batteries slowly lose their charge over a few days anyway. That is an
inherent problem with the technology.
Fortunately they charge relatively quickly, for which we are willing to
forgive that fault. Fact is, most battery "technology" is simple sales hype.
Lithium ion batteries, for example, have twice the energy density of NiCds,
but they are not usually rechargeable. That's not good. Many new battery
chemistries have been developed, but the best density ones are almost never
rechargeable. Also, they use silver or other expensive chemicals. The
venerable old carbon-zinc LeClanche cell was a pretty good method, and you could
recharge it, albeit slowly. Sure, alkalines are more power dense, but they do

Not hard to think about at all- just hard to find realistic methods of doing
it. If these things were easy, they would be all over the place already.
