N.Tesla at the turn of the twentieth century performed experiments where he claims to have transmitted electrical energy wirelessly for rather large distances. He said that he could complete this transmission even if the receiver was within a Faraday cage. Most researchers of his time dismissed his claims as false and no theoretical explanation was found for his claims. Recently, there has been some inventions based on his experiences. There are inventions based on the propagation of a vector electromagnetic potential when fields are present (US4429288 Gelinas Patent) and even when there are no electric fields present (US5845220 Puthoff Patent). More recently, the MIT has developed a number of patents on wireless transmission of electricity (US7,741.734B2 and others) that are based on the coupling of resonance modes of resonators separated by some distance. They confirm Tesla’s claim that this phenomenon is not radiative. They explain that is based on the evanescent field which is a field around an electromagnetic excitation that decays exponentially. If two resonators have their frequencies close enough to each other and are within the evanescent field of each other, there modes would be coupled and energy transmission takes place from one resonator to the other.
Interest has increased recently in the possibility of the existence of scalar and longitudinal solutions to Maxwell’s equations that conform to Tesla’s results.
We have a team of researchers from different countries that is attempting to develop the theoretical framework for Tesla’s findings with the goal of generating cheaper energy and transmitting it wirelessly to homes and to devices.
