Arrow The Meaning of Unity in Energy Conversion Systems by Jim Murray



The Meaning of Unity in Energy Conversion Systems by Jim Murray Initially, it had been assumed that a simple ratio computed by dividing the output power by the input power would provide a reliable yardstick for motor power efficiency. The basic idea, was sound, for the closer the quotient came to unity, the nearer the motor efficiency would be to 100%. Hence began the so-called “Quest for Unity.”

However, early “electric engines” were very inefficient, probably delivering no more than 30% of the electrical input power to the output shaft. Therefore, it quickly became evident that not all of the applied power was being converted to a mechanical output. Clearly, inefficiencies were involved, and they would have to be accounted for. Until this was complete, the simplified approach to establishing a Factor of Unity could not be realized.

What is remarkable, in the history of motor development, is the curious degree of synergy that seems to have accompanied these early pioneering efforts. Between 1839 and 1850 the British Brew Master James Joule conducted an elegant series of experiments, in which he sought to unify electrical, chemical and thermal phenomena by demonstrating their inter-convertibility and their quantitative equivalence. The results of Joule’s work were published in the Philosophical Transactions of the Royal Society, with a very impressive title: “On the Mechanical Equivalence of Heat.”

The contributions of Lord Kelvin must be considered next. His paper, “The Dynamical Equivalent of Heat,” published in 1851, contended that energy could be “lost to man irrecoverably; but not lost to the material world”. Thomson was thus the first person to understand that all energy changes involve energy dissipation, and losses.

During the second half of the nineteenth century Kelvin and other scientists, including Clausius, Rankine, Maxwell and, Boltzmann, continued to develop these ideas. Their combined efforts resulted in the establishment of the Science of Thermodynamics; with Conservation of Energy as its First Law and the Dissipation of Energy as its Second Law.

Accordingly, motor researchers were thus made aware of the extreme importance of classifying all known motor losses, and accounting for them with the same degree of accuracy as would be exhibited in the well established science of corporate book-keeping.

Ultimately, such practices would lead to the development of two principle kinds of Efficiency Measurements, both very valuable in all research pertaining to rotating components, but, particularly valuable for developing an understanding of over-unity as a scientific fact. Both efficiency concepts shall be fully explained in this presentation.

Hello to all,

I had the pleasure of attending J. Murray's 2018 conference presentation and also viewing the video. This presentation is a classic methodology developed by Jim with his many years of experience in this field. The presentation, in my mind, is a prerequisite for any one, who is even remotely interested in the Alt Energy field, to gain an understanding of the over unity verification process and the multiple influences of all the variables involved. If you are a serious experimenter do get this seminal video - otherwise you are "fake news" when it comes to describing what you have found.

Best to all,
Yaro
