This report describes electrical measurements performed by the National Bureau of Standards on Joseph Newman's device. The tests were conducted between March and June 1986 at the request of the U.S. Patent and Trademark Office in accordance with several court orders. As a Federal science and engineering research laboratory that specializes in measurements and is responsible for maintaining U.S. standards for electricity, NBS has extensive experience and facilities for measuring the performance of electrical equipment. The purpose of the measurements was to test the inventor's claim that the output power from the device was greater than the power which was supplied to the device from a battery pack. NBS was not requested to examine the theory behind the operation of the device.

The tests consisted of electrical measurements of the power drawn from the battery pack by the device (input power) and separate as well as simultaneous measurements of the output power. These measurements were done with several different sets of conventional, well-documented test instruments. Due to the specialized nature of the equipment, however, the instrumentation would not generally be found in most research laboratories. The electrical characteristics of the device, especially the sharp spikes in input and output waveforms, necessitated a variety of extensive and careful measurements and experimental checks to ensure that valid data resulted. Equipment selection was critical.

The device's efficiency -- defined as the ratio of output power to input power -- varied depending on the voltage, load on the device, and the degree of degradation of the tape on the commutator of the device. If the device simply transferred the power from the batteries to the load, its efficiency would be 100 percent; in no case did the device's efficiency approach 100 percent.

At all conditions tested, the input power exceeded the output power. That is, the device did not deliver more energy than it used.
