ELF/VLF WAVE GENERATOR USING A VIRTUAL VERTICAL ELECTRIC DIPOLEKonstantinos PAPADOPOULOS
I have found a few unusual cases in which there was a very strong electrical field next to the headboard of a bed because of the routing and positioning of an electric meter in the service entrance cable. There are photos of that in this article series. But it's quite unusual. The ...
ELF/VLF wave generator using a virtual vertical electric dipole A high efficiency system generates a VED virtual antenna by taking advantage of the vertical electric field created by natural effects in the lower ionosphere at latitudes in the vicinity of the dip equator. An ionospheric heater is ...
