Radio waves are generated by advertising revenue paid to radio and television broadcast facilities across the globe; with the exception of the BBC of course, which are instead paid for by the tax pounds of the citizens of the United Kingdom. Radio waves carry enough energy to excite a crystal tuned to the specific frequency of the wave. That energy is then fed into an amplifier and passed on to your speakers. If a "super crystal" could be made that oscillates at all frequencies simultaneously it could generate enough energy to do "something." Until such a system exists it would be hard to tell how much energy it could generate. And even then, see my caveat in the next paragraph. The problem I see with this technology is that if I were driving through a canyon and lost all reception to RF my car would stall, at which point I would have to push it out of the canyon to get reception again. Most canyons are pretty deep, that would make a hell of a push! However, I think that there is actually some merit to the idea. The energy could be stored in a battery in a similar fashion to brake regenerating systems in use on todays hybrid cars. Would it generate enough power to compensate for the energy required to move weight of the equipment? |
