741. Is it true that Tesla invented a way to send electrical power without the use of power lines? If so, how? - BS
Yes. Tesla found that the alternating electromagnetic fields around a large high frequency transformer could propel currents through wires or lamps that were located at a moderate distance from the transformer. But this technique of using the alternating fields near a transformer to provide power aren't very practical—there is too much power wasted through radiation or in heating things that aren't meant to be heated.
