Keely
"For ten years Keely's demonstrations were confined to the liberation, at will, of the energy he had "stumbled over" while experimenting on vibrations in 1872; and his efforts were put forth for the construction of "the perfect engine," which he had promised to the Keely Motor Company. He made the mistake of pursuing his researches on the line of invention instead of discovery. All his thoughts were concentrated in this direction up to the year 1882. Engine after engine was abandoned and sold as old metal, in his repeated failures to construct one that would keep up the rotary motion of the ether that was necessary to hold it in any structure. Explosion after explosion occurred, sometimes harmless to him, at other times laying him up for weeks at a time.
Two more years were lost in efforts to devise an automatic arrangement, which should enable the machine, invented by Keely for liberating the energy, to be handled by any operator, and it was not until 1884 that steady progress was seen, from years to years, as the result of his enlarged researches. When Keely was asked, at this time, how long he thought it would be before he would have the engine he was then at work upon ready to patent, he illustrated his situation by an anecdote: "A man fell down, one dark night, into a mine; catching a rope in his descent, he clung to it until morning. With the first glimpse of daylight, he saw that had he let go his hold of the rope he would have had but a few inches to fall. I am precisely in the situation of that man. I do not know how near success may be nor yet how far off it is."
August 5th, 1885, the New York Home Journal announced that Keely had imprisoned the ether; and, as was then wrongly supposed, that the unknown force was the ether itself; not the medium of the force, as it is now known to be." [Bloomfield-Moore] [Ether the True Protoplasm]
"True philosophy, when reached, said Professor George Bush, will conduct us into the realm of the spiritual as the true region of causes, and will disclose new and unthought of relations between the world of matter and of mind.
It is these unthought of relations which Keely's system of sympathetic physics brings to light; opening out a field for research which lies beyond the boundaries of our present knowledge. As yet he has been unable to satisfy his own penetrating mind in regard to all the hypothesis which his various discoveries have led him into formulating. He has himself, in his search for truth, pursued the wrong path too often, and made too many errors, not to welcome refutation of them, and acknowledge his mistakes when brought before him.
The title which he has given to the latent current of the triune polar flow that he discovered in 1872, "polar negative attraction," undoubtedly conveys the idea that this flow is an agent closely allied to magnetism; but such is not the case.
This latent element exists in the interstitial conditions of all nature's triple streams of force; in electricity, in magnetism, in gravity; and is the dominant current in each of these, maintaining a sympathetic relation to the high or compound luminous, which manifests itself when the proper mechanical requirements are used. It is entirely foreign in character to the elements now in commercial use. Researchers will always find before them a limitless beyond, comprehended only by the Infinite One." [Veil Withdrawn]

Today's forest, land, water and energy resources management and all branches of contemporary science - whatever the specialist discipline - are tragic mistakes, whose terrible consequences will only become apparent when the irrefutable truth has been grasped through practical demonstrations; when people see and understand what is created when any thing - above all air and water - is moved unnaturally and therefore wrongly. Through this absurd form of motion precisely that temperature-form is produced which gives rise to the developmentally harmful cavitation current that wise Nature uses to remove everything from the path of evolution, which for one reason or another is unfit for the growth and formation of the relatively highest quality.

Because of this curious attitude, conventional science has made a serious mistake, which we have to thank for the general economic decline, the world-wide unease and unrest, and not least, the constant wars. As long as this mistake remains uncorrected, any lasting peace is unthinkable, for owing to the serious disruption of natural development, the quality of the soil is declining, the shortage in raw materials is increasing and the various sources of food and fodder are dwindling in the same ratio that the population is increasing. It is therefore obvious that under such circumstances no lasting peace can come about. [The Energy Evolution - Harnessing Free Energy from Nature, The Liquefaction of Coal by Means of Cold Flows]

“I hope that in this year to come, you make mistakes.
Because if you are making mistakes, then you are making new things, trying new things, learning, living, pushing yourself, changing yourself, changing your world. You're doing things you've never done before, and more importantly, you're Doing Something.
So that's my wish for you, and all of us, and my wish for myself. Make New Mistakes. Make glorious, amazing mistakes. Make mistakes nobody's ever made before. Don't freeze, don't stop, don't worry that it isn't good enough, or it isn't perfect, whatever it is: art, or love, or work or family or life.
Whatever it is you're scared of doing, Do it.
Make your mistakes, next year and forever.” [Neil Gaiman]
