Greg, nobody has ever to this day made a Tesla coil that I have ever heard of capable of using the earths natural current to move objects. And now! they don't need vacuum tubes lol. They make great gizmos for lighting etc.




Think we're on different wavelengths here Ron, or I misunderstood the original post about Tesla. I'm talking about Teslas work with trying to use giant Tesla transmitters and receivers to send power across great distances. I realize he was also working on ways to utilize the Earths own magnetic field (not sure why that seems like such a far fetched idea, perhaps you are more in tune with electronics and magnetism than I). But I believe one of his concepts was to basically transmit power waves the same way that we transmit radio waves, except that you would have an end user with a Receptor to convert that power back into energy to drive motors, lights, etc... IF I'm not completely mistaken that is how Microwaves were stumbled upon, which does exactly that, transmits power which creates heat when it strikes an object such as food. Further, that is basically the premise behind directed energy weapons which we are working on, and which I believe have been proven to be entirely feasible, not just sci-fi. Maybe not ready for primte time, but certainly within the scope of reality and not too distant technology. Think the biggest problem with that whole concept isn't whether or not it could be done, but the health effects of being exposed to the EM Radiation, the impact on communications systems, electrical appliances, and so on.

I might add, with regard to open minded-ness, sci fi and so on, in the 1960's a television show aired in which there were men in space, who had handheld devices which could be used to communicate over great distances simply by flipping the "communicator" open, and where anti-matter was used as a propulsion source, and where science officers could read books and documents on an electronic tablet, or seek information. All pie in the sky sci-fi! Well, since then, we've fielded numerous manned space missions, are planning a trip to Mars, have proven that anti-matter is real, and I have long ago traded my flip phone for a handheld PC that can seek information from any source on the globe via the internet. I can also get a tablet which will not only allow me to read any book posted electronically, but watch full length movies, scan documents, and so on. The sci fi that you grew up on is slowly materializing. Oh, didn't even mention robots that are so small that they are almost invisible to the naked eye, and are built under microscopes, and which can be put into your body to fight things like cancer....
