N-Machine and Bruce DePalma

Yet “proof of principle” for his invention was apparently provided when a large N-Machine, dubbed the Sunburst, was built in 1978 in Santa Barbara California. The Sunburst machine was independently tested by Dr. Robert Kincheloe, professor emeritus of electrical engineering at Stanford University. In his 1986 report (presented to the Society for Scientific Exploration, San Francisco, 6/21/86), Kincheloe noted that the drag of the rotating magnetized gyroscope is only 13 to 20 percent of a conventional generator operating at an ideal 100 percent efficiency. The DePalma N-Machine therefore could produce electricity at around 500 percent efficiency.

In Kincheloe’s cautious summary: “DePalma may have been right in that there is indeed a situation here whereby energy is being obtained from a previously unknown and unexplained source. This is a conclusion that most scientists and engineers would reject out of hand as being a violation of accepted laws of physics and if true has incredible implications.”
“The jury is still out on the DePalma N-Machine,” says physicist Harold Puthoff, a senior fellow at the Institute for Advanced Studies in Austin, Texas. “It isn’t clear where the reported excess energy is coming from – whether out of the electromagnetic field or as the result of some anomaly associated with rotating bodies in terms of inertia. The DePalma machine needs to be replicated on a broad scale to see if it actually works. Though I’m rather skeptical, I certainly would encourage independent laboratory experimentation. While such a phenomenon would have seemed to absolutely go against the law of energy conservation a number of years ago, we now recognize that the potential for extracting energy out of so called empty space is in fact a reality.”
Dr. Puthoff believes that a new, non polluting energy source may be achieved by tapping the force of random fluctuations of jostling atomic particles within a vacuum. “We now know that empty space is filled with what are called vacuum fluctuations: huge amounts of energy that suddenly burst forth from the nothingness of space. Zero Point Energy is the general term applied to the theories that attempt to explain the concept of tapping into the abundant power available directly from the vacuum of space itself.
DePalma described his N-Machine and outlined a theory to explain its workings in a paper, “On the Possibility of Extraction of Electrical Energy Directly From Space,” published in the British science journal, Speculations in Science and Technology (Sept 1990, Vol 13 No 4). So far, the scientific establishment either has ignored DePalma’s controversial claims or remains unaware of them.
DePalma is quick to point out that the N-Machine is not a perpetual motioN-Machine, that mythical contraption long sought by many frustrated inventors. “The perpetual motioN-Machine is only supposed to run itself. It could never put out five times more power than is put into it. Perpetual motion schemes used conventional energy sources, whereas the N-Machine is a new way of extracting energy from space.”
Meanwhile, other countries, notably India and Japan, are vigorously pursuing what might prove to be a technological breakthrough. (is this yet one more example of the Invented in USA/Made in Japan syndrome, the outcome of American shortsightedness and vested interests?) In India, eminent engineer Paramahamsa Tewari is currently testing his invention, called the Space Power Generator (SPG), which essentially replicates DePalma’s N-Machine. With 5 kilowatts total power input, the SPG is reportedly yielding 30 kilowatts of electrical power output. (correspondence to B. DePalma 8/13/90).
Tewari, a senior engineer with India’s Department of Atomic Energy-Nuclear Power Corporation, also directs the Kaiga Project, India’s largest atomic power facility, in Karnataka. He freely acknowledges his debt to DePalma, who has shared his experimental results with Tewari for many years. According to Tewari, “The electrical power generated by the Space Power Generator is indeed commercially viable and should be brought to the notice of the general public.” He has urged India’s Atomic Energy Commission to create an independent research group to advance free energy technology.Tewari also credits John Wheeler, the prominent American physicist and discoverer of the black hole, for his steady encouragement. Wheeler, who had been searching for a mathematical theory that would predict free energy, applauded Tewari for his efforts to develop such a theory, and the two scientists corresponded for a number of years.
