Tesla stated: "As to the transmission of power through space, that is a project which I considered absolutely certain of success long since. Years ago I was in the position to transmit wireless power to any distance without limit other than that imposed by the physical dimensions of the globe. In my system it makes no difference what the distance is. The efficiency of the transmission can be as high as 96 or 97 per cent, and there are practically no losses except such as are inevitable in the running of the machinery. When there is no receiver, there is no energy consumption anywhere. When the receiver is put on. it draws power. That is the exact opposite of the Hertz-wave system. In that case, if you have a plant of 1,000 horsepower (750 kW), it is radiating all the time whether the energy is received or not; but in my system no power is lost. When there are no receivers, the plant consumes only a few horsepower necessary to maintain the vibration; it runs idle, as the Edison plant when the lamps and motors are shut off.""
These amazing facts are explained by Corum, Spainol and Corum: "...the distinction between Tesla's system and 'Hertzian' waves is to be clearly understood. Tesla, and others of his day, used the term 'Hertzian waves' to describe what we call today energy transfer by wireless transverse electromagnetic (TEM) radiation...no one wants to stand in front of a high-power radar antenna. For these, E and H are in phase, the power flow is a 'real' quantity (as opposed to reactive power), and the surface integral of E x H (Poynting vector) is nonzero. The case is not so simple in an unloaded power system, an RF transformer with a tuned secondary, or with a cavity resonator. In these situations, the fields are in phase quadrature, the circulating power is reactive and the average Poynting flux is zero—unless a load is applied. They deliver no power without a resistive load. These are clearly the power systems which Tesla created. The polyphase power distribution system was created by him in the 1880s and inaugurated at Niagara Falls in 1895. The RF transformer was invented and patented by him in the 1890s. Terrestrial resonances he experimentally discovered at the turn of the century. And, for the next 40 years he tried to bring through to commercial reality this global power system. Today, millions of us have working scale models of it in our kitchens, while the larger version sits idle."26
Note that for a spherical electrostatic pulse discharge, E is radial and H is helical since J is radial (longitudinal or irrotational current).2' This is a total anathema to transverse wave physics textbook images of E and H, which are normally perpendicular to each other.
