Newman"s Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine.United States district court requested that Newman"s machine be tested by the National Bureau of Standards (NBS). The NBS concluded in June 1986 that output power was not greater than the input.pseudoscientific and his claims as false.

In 1979, Newman submitted an application for his device to the United States Patent and Trademark Office.United States District Court requested a master of the court to make the final decision. William E. Schuyler, Jr, former Commissioner of U.S. Patent Office, Washington, DC was chosen by the court to make the final decision to award the patent or not award the patent to Newman. Schuyler concluded that evidence to support Newman"s claim was overwhelming and found no contradictory factual evidence.

However, the judge ordered Newman"s machine to be tested by the National Bureau of Standards (NBS). The National Bureau of Standards (NBS), now known as the National Institute of Standards and Technology (NIST), by request of the patent office, tested the device for several months and got negative results. In every case presented in the NBS report, the output power was less than power input from the battery pack, and therefore the efficiency was less than 100%. The court therefore upheld the rejection of the patent application.

Eric Krieg"s Arizona radio show was a reaction to Joseph Newman"s long-running campaign to have himself and his "Energy Machine" hailed as world saviors. Here is some background for readers unfamiliar with Newman"s ideas. I hope eventually to address them in greater technical detail on PhACT"s Web site.

Most of what appears here is drawn from Newman"s own magnum opus, "The Energy Machine of Joseph Newman." This 9" by 11" book is 1 3/4" thick, has around 590 pages and is bound in white fake leather with the title embossed in gold. It contains an amazing hodgepodge of material. There"s Newman"s attempt to "explain" magnetic forces in terms of "gyroscopic particles." There"re descriptions of his machine, complaints about the patent office not testing it correctly, many press cuttings, and reprints of the noncommittal letters Newman has received from people he has pestered. His rewriting of textbook science extends from statics via electromagnetic theory to thermodynamics and orbital mechanics.

One of Newman"s amazing discoveries is that coils having many turns of wire generate a given magnetic field with a lower input current than coils with fewer turns. Well even Michael Faraday knew that. Next he claims that increasing the number of turns reduces the power used. In this calculation he ignores the resistance of the wire. It seems to have escaped Newman that a static magnetic field requires no power to maintain it. Only the resistance of the copper wire is dissipating energy. For example, a superconducting magnet requires a power input to create a field but none to maintain it.

Before I read his book I knew, based on simple physical principles, that Newman"s machine could not possibly output more energy than is put into it. However, I was aghast when I saw the photographs of the motor which Newman submitted to the patent office. It consists of a permanent magnet rotor with a commutator on its shaft. Standing alongside this is an air-cored solenoid. Now the first principle of making an efficient electric motor is to provide a direct magnetic path through the armature and field coils. Normally one uses a ferromagnetic core and all air gaps are made as small as practical. No motor consisting of a rotating magnet with a coil alongside it has a hope of being more than a few percent efficient.

* Note Newman"s fallacious reasoning here. Conventional electrical theory perfectly explains the observed behavior of all motors, including Newman"s. Adopting Newman"s incorrect theory can"t magically make motors work any differently. In any case, there is no need to modify a theory until there are experimental grounds for supposing it to be flawed. Newman has not shown any such grounds.

Abstract: A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.
