Original poster: Gregory Morris <gbmorris@xxxxxxxxx> Wasn't Tesla's coil tuned so as to minimize losses from spark? He was trying to use the machine to transmit power through the earth, not light up the sky, right? Greg
Greg, That's mostly a matter of installing a large topload so the sparks can't break out. Tesla's Wardenclyffe project in Long Island had such a large topload, but he ran out of funding. Transmitting power through the earth is not practical anyway. John **************************************See what's free at http://www.aol.com.
