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? As I said, it needs to be investigated. Just because we aren't AWARE of a method to utilize radio waves as an energy source doesn't mean we can't do it. We just need to learn how through experimentation, trial and error. Consider that anything with a physical quality can be made to DO something... Why say "No, it can't be done?" People said that about lots of things and were later proven wrong, once SOMEONE with the interest, time and money bothered to experiment. I believe that radio waves will be used in a two-stage system at first, powering light that can be used on photovoltaic cells which will then provide electricity. That seems to be the most logical and simplest early application of what will be a dynamic new technology. CONSIDER: Water alone doesn't produce "energy" in a usable state, but when we route it through a dyno (just like air/exhaust through a turbine/impeller) its physical properties become very useful in generating electricity. This same thing may possibly be achieved with radio or sound waves. Light doesn't do much for use except make things visible, yet it "fuels" photovoltaic cells to produce electricity. If we can find a way to use radio or sound waves to power or provide light without the Sun, photovoltaic cells will become more practical. Never say "It can't be done" until all avenues have been traveled. I think it CAN be done. Regarding loss of signal, who's to say at this point that the particular radio waves could not be generated ONBOARD a vehicle? Here's a stretch, but suppose we could use Quartz in some fashion to assist ingenerating a short-distance radio wave that the vehicle would use? Put a few well-turned rocks in the car and drive until the parts wear out. Jerry aka LGO **************Gas prices getting you down? Search AOL Autos for fuel-efficient used cars.
