A Series of Lessons in Gnani Yoga Successive stages, from food gathering to trading and manufacturing, required more energy—human energy, animal energy, and eventually mechanical energy. Civilization and Beyond Learning from History A certain amount of mechanical energy had been used up and a certain amount of heat had appeared. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told Not only was it now possible to convert mechanical energy into electricity cheaply and in illimitable quantities, but electricity at once showed its ubiquitous availability as a motive power. Edison, His Life and Inventions Our woods and forests are also sources of mechanical energy, because they have the power of uniting with the atmospheric oxygen. Fragments of science, V. 1-2 This Creative Will is not a mere blind, mechanical energy or force—it is far more than this. A Series of Lessons in Gnani Yoga The entire plant, comprising over sixty steam-engines, and operating 127 dynamos, represented a most stupendous display of mechanical energy hitherto unequaled. By Water to the Columbian Exposition It is the work of the dynamo to convert mechanical energy into the form of electrical energy. Steam, Steel and Electricity How many foot-pounds of electricity can be got out of 100 foot-pounds of mechanical energy? Edison, His Life and Inventions At some cheap source of energy, say, at a waterfall, a waterwheel is employed to drive a dynamo or generator, thus converting mechanical energy into electrical energy. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents There is every indication of a steady increase in this proportion of mechanical energy, in this emancipation of men from the necessity of physical labour.

The Principles of Aesthetics The motor, in turn, changes this electrical energy back again into mechanical energy. Steam, Steel and Electricity For him, the arising of heat represented a disappearance of mechanical energy. Man or Matter Then, as the downward force triumphed over the mechanical energy in the craft, she began to settle again, and soon was descending, if that was the direction, as fast as before.

The Age of Invention : a chronicle of mechanical conquest He wished to be shown that changes in form caused evolution in force; that chemical or mechanical energy had by natural selection and minute changes, under uniform conditions, converted itself into thought. The Education of Henry Adams All that Goliah had predicted that the intelligence of mankind could accomplish with the mechanical energy at its disposal, came to pass. Revolution, and Other Essays She cannot exert as much mechanical energy in any other way. In Defense of Women The dynamo converts mechanical energy into electric energy.
