Self recharging battery | |||||||||||||||||
Scientists search for a way to use free and environmental energy. But all such energies (solar, wind ....) have restrictions (sunny day for solar, windy day for wind energy....). The only energy that is non-stop and everywhere is electromagnetic noise. It's a pity that nobody address it as an energy and everyone tries to get rid of it. If only we could collect and store that energy we would have a self-recharging battery. Now since electromagnetic noise is random (and can be difficult to use) there could be a broadcast (or in all the existing as RDS or Teletext) that would contain periodic (usable) pulse and the "battery" could collect with some sort of antenna.

EM noise just isn't manageable, or dense enough to collect. For man made EM noise, it would be easier not to make the EM noise to begin with.
Any current systems to absorb EM noise generally convert it to heat anyways, if that counts for anything.
Geothermal and hydroelectric don't work dependant on weather.
ArchAngel,
That is true. But they are depended on particular places (so they cannot be used for "mobile" batteries).
