There has also been a very great deal more research published that finds no such effects. See, for example: http://www.faqs.org/faqs/medicine/powerlines-cancer-faq/ If there were hundreds of amps at hundreds of kHz circulating in any power distribution system, it would collapse due to system capacitor heating and vast over-voltages on system inductors. -- OOO - Own Opinions Only.
