Keely
Newton, who scoffed at Epicurus's idea that "gravitation is essential and inherent in matter," asserted that gravity must be caused by an agent acting, constantly, according to certain laws. Heat, gravity, light, electricity, magnetism, chemical affinities, are all different phases of the primal force discovered by Keely, and all these forces, it is said, can be obtained from a single ray of sunlight. "The evidence of unity or oneness even between the physical, vital, mental, and spiritual is seen in the light of this law of correlation," says J. J. Smith. "A great portion of our muscles contract and relax in obedience to our wills, thereby proving that the mental force can be, and is, in every such instance actually converted into the muscular or the physical." Keely demonstrates the truth of this assertion, claiming that "all forces are indestructible, immaterial, and homogeneous entities, having their origin and unity in one great intelligent personal will force."

"So stood matters with Mr. Keely until a few years ago, when, fortunately for his hopes of success, a new conception came to him by accident, as he asserts; one of those happy accidents, it would appear, which only men of the unusual capacity called genius are ready to take advantage of. Just what this conception was, Mr. Keely, with business-like caution, keeps to himself. The public, for the present at least, must be content with its visible results; but these are sufficiently noteworthy to amply repay consideration. They indicate two things: First, that Mr. Keely is no longer dealing with a power arising from gaseous pressure; and, second, that he has made this power capable of producing rotation, levitation, and other effects of mechanical energy. What he claims, in regard to the source of his new system of power, is that he is able to draw vibratory energy directly from space by the aid of special resonating expedients, and that this energy can be made to yield powerful attractive and repulsive force and be converted into vigorous rotary motion through the use of certain apparatus. The power obtained, he asserts, is duplex, or has two opposed conditions, like the positive and negative states of electricity. Mr. Keely denominates these conditions positive and negative, though with the reservation that these terms do not imply excess and deficiency, but simply opposite conditions of energy. He is able, he declares, to disturb the equilibrium of these opposed states of vibratory activity as they exist in the elements of nature, to draw them separately into his apparatus, and to produce mechanical motion as a result of the effort of nature to restore the disturbed equilibrium."

Schauberger
Many suggestions have already been made as to how losses in energy, pressure or velocity arising in the transport of liquids or gaseous media can be reduced. Thus for the purposes of inhibiting the formation of air-bubbles, which provoke an increase in the resistance to flow, a British Patent No. 409,528 for a pipe has been published, which is wound in a screw-form manner and its cross-sectional surfaces are formed by two arcs of a circle. From the British Patent No. 28,5343 of 1913 AD, the application of a pipe with an egg-shaped cross-section was made known, which was provided with flow-directing slats to inhibit the formation of vortices. In the U.S. Patent No. 1,655,197 as well as in the Schauberger - Swiss Patent No. 126637, cylindrical or conical pipes were proposed with the object of reducing friction by converting it into rotation, for which the pipe axis served as the rotational axis. Lastly, the Schauberger - Austrian Patent No. 28099 depicts the use of indented and twisted pipes.
