In conventional electrical engineering, the radiant or 'longitudinal' spike or 'pulse' produced when the magnetic field in a coil collapses, has generally been treated as a nuisance, since it can damage sensitive electronics. However, these high-energy pulses are actually a different form of electricity (cold electricity) that can be utilized to add energy to many open systems designs. This is the basic process behind the operation of the Bedini 'SG' Energizers (see first option below). Many devices using this and other more exotic forms of pulsed energy can be explored on our website. (See: Radiant Energy, Pulsed Power, Aerial Systems, Resonance, Electromagnetic, Superconductors).
