Following in Faraday's footsteps, DePalma in 1978 speculated that free energy could be tapped from the matrix of space simply by magnetizing a gyroscope. Half of the flywheel is the norht pole, the other half is the south pole. One elctrical contact is put on the axle, another contact is placed on the outer edge of the gyroscope, and presto, electricity is taken directly out of the magnet itself. Then, in 1978, the aforementioned Sunburst homopolar generator was built. Tests determined that is output power greatly exceeded the input needed to run the machine, that it was much more efficent that an induction generator.
Opinions differ as to the exact mechansms by which the N machine generates energy.
In 1977 Tewari created a minor sensation when he put forth the theory that space is filled with a dynamic medium whose swirling motion is the sourc of all matter and energy. He readily admits that this soudns incredible, by the yardstick of known laws of physics. Tewari says he never would have developed his theory had he been trained as a physicist rather than as an engineer, since his ideas differ so radically from conventional physics. He is attempting to conceptualize what's happening between the atoms and where the energy is liberated. The only way you know it's there is to distort it in some way, and the simplest way to distort space is with a magnet.
