Here we are in 2018, over a hundred years later speculating about what could have been Nikola Tesla’s secret. I then think to myself: if only I could show you what I read, you would understand that there is no secret. When I read his articles and patents from 1900 onward, what I see is a man desperately trying to get his views across. He tries again and again in many different ways, but no-one seems to see what I see.
It is my sincere wish that one day people will read Tesla’s articles and really understand what he is saying.
So… Let me take you by the hand an walk you through his most famous article: “The Problem of Increasing Human Energy”, published in Century Illustrated Magazine of June 1900.
This sixth part is an introduction to the main topic "Harnessing the Sun’s Energy" which is also in the subtitle of this article.
Tesla literally gives us a key to understand one of the earlier parts and tells us that the next key is iron. Can you guess what it would stand for?
Previous parts can be found here:

THE THIRD PROBLEM: HOW TO INCREASE THE FORCE ACCELERATING THE HUMAN MASS
—THE HARNESSING OF THE SUN'S ENERGY.
Of the three possible solutions of the main problem of increasing human energy, this is by far the most important to consider, not only because of its intrinsic significance, but also because of its intimate bearing on all the many elements and conditions which determine the movement of humanity. In order to proceed systematically, it would be necessary for me to dwell on all those considerations which have guided me from the outset in my efforts to arrive at a solution, and which have led me, step by step, to the results I shall now describe. As a preliminary study of the problem an analytical investigation, such as I have made, of the chief forces which determine the onward movement, would be of advantage, particularly in conveying an idea of that hypothetical "velocity" which, as explained in the beginning, is a measure of human energy; but to deal with this specifically here, as I would desire, would lead me far beyond the scope of the present subject. Suffice it to state that the resultant of all these forces is always in the direction of reason, which therefore, determines, at any time, the direction of human movement. This is to say that every effort which is scientifically applied, rational, useful, or practical, must be in the direction in which the mass is moving. The practical, rational man, the observer, the man of business, he who reasons, calculates, or determines in advance, carefully applies his effort so that when coming into effect it will be in the direction of the movement, making it thus most efficient, and in this knowledge and ability lies the secret of his success. Every new fact discovered, every new experience or new element added to our knowledge and entering into the domain of reason, affects the same and, therefore, changes the direction of movement, which, however, must always take place along the resultant of all those efforts which, at that time, we designate as reasonable, that is, self-preserving, useful, profitable, or practical. These efforts concern our daily life, our necessities and comforts, our work and business, and it is these which drive man onward.
This last problem is obviously the most important, and Tesla starts out on a topic that looks like resonance. Also he states the importance of understanding that “hypothetical velocity”, the voltage or temperature or a combination of those two. I think Tesla not just talks about resonance as in the Tesla coils but also in the effect needed to create in the atmosphere in order to lower its resistance to ionization, which is very closely related to the subject of this chapter: harnessing the Sun’s energy.
But looking at all this busy world about us, on all this complex mass as it daily throbs and moves, what is it but an immense clock-work driven by a spring? In the morning, when we rise, we cannot fail to note that all the objects about us are manufactured by machinery: the water we use is lifted by steam-power; the trains bring our breakfast from distant localities; the elevators in our dwelling and our office building, the cars that carry us there, are all driven by power; in all our daily errands, and in our very life-pursuit, we depend upon it; all the objects we see tell us of it; and when we return to our machine-made dwelling at night, lest we should forget it, all the material comforts of our home, our cheering stove and lamp, remind us of how much we depend on power. And when there is an accidental stoppage of the machinery, when the city is snowbound, or the life sustaining movement otherwise temporarily arrested, we are affrightened to realize how impossible it would be for us to live the life we live without motive power. Motive power means work. To increase the force accelerating human movement means, therefore, to perform more work.
This is the first mention (in this article) of a clockwork driven by a spring. At this point it is not yet very clear what he means by this. In this paragraph everything around us, in fact us included, is the clockwork and motive power or energy is the spring. Both the natural world as the world that we have created require a constant supply of energy.
So we find that the three possible solutions of the great problem of increasing human energy are answered by the three words: food, peace, work. Many a year I have thought and pondered, lost myself in speculations and theories, considering man as a mass moved by a force, viewing his inexplicable movement in the light of a mechanical one, and applying the simple principles of mechanics to the analysis of the same until I arrived at these solutions, only to realize that they were taught to me in my early childhood. These three words sound the key-notes of the Christian religion. Their scientific meaning and purpose now clear to me: food to increase the mass, peace to diminish the retarding force, and work to increase the force accelerating human movement. These are the only three solutions which are possible of that great problem, and all of them have one object, one end, namely, to increase human energy. When we recognize this, we cannot help wondering how profoundly wise and scientific and how immensely practical the Christian religion is, and in what a marked contrast it stands in this respect to other religions. It is unmistakably the result of practical experiment and scientific observation which have extended through the ages, while other religions seem to be the outcome of merely abstract reasoning. Work, untiring effort, useful and accumulative, with periods of rest and recuperation aiming at higher efficiency, is its chief and ever-recurring command. Thus we are inspired both by Christianity and Science to do our utmost toward increasing the performance of mankind. This most important of human problems I shall now specifically consider.
“Work with periods of rest”, “carefully applied so that it will be in the direction of the movement”. This seems to refer to resonant action, as mentioned earlier. Also we know from the earlier chapters that since every force is met with an equal and opposite force every movement in nature must be rhythmical.
To me this chapter looks like a summary and closure of what is mentioned before and intro to the main topic which is how can we get energy without burning fuel, and preferably as close as possible to the source.
THE SOURCE OF HUMAN ENERGY
—THE THREE WAYS OF DRAWING ENERGY FROM THE SUN.
First let us ask: Whence comes all the motive power? What is the spring that drives all? We see the ocean rise and fall, the rivers flow, the wind, rain, hail, and snow beat on our windows, the trains and steamers come and go; we hear the rattling noise of carriages, the voices from the street; we feel, smell, and taste; and we think of all this. And all this movement, from the surging of the mighty ocean to that subtle movement concerned in our thought, has but one common cause. All this energy emanates from one single centre, one single source—the sun. The sun is the spring that drives all. The sun maintains all human life and supplies all human energy. Another answer we have now found to the above great question: To increase the force accelerating human movement means to turn to the uses of man more of the sun's energy. We honour and revere those great men of bygone times whose names are linked with immortal achievements, who have proved themselves benefactors of humanity—the religious reformer with his wise maxims of life, the philosopher with his deep truths, the mathematician with his formulæ, the physicist with his laws, the discoverer with his principles and secrets wrested from nature, the artist with his forms of the beautiful; but who honours him, the greatest of all,—who can tell the name of him,—who first turned to use the sun's energy to save the effort of a weak fellow-creature? That was man's first act of scientific philanthropy, and its consequences have been incalculable.
The Sun is the source of all our energy, so to get more energy we have to look at our Sun and find a means to draw more energy from it. Referring back to Tesla's article of 1932-10-13: “The Eternal Source of Energy of the Universe, Origin and Intensity of Cosmic Rays”, where Tesla also speaks about a clockwork driven by a spring, we read that it is not just our Sun, but all stars in the universe that emit vast amounts of energy. Cosmic rays are a constant source of energy, day and night.
From the very beginning three ways of drawing energy from the sun were open to man. The savage, when he warmed his frozen limbs at a fire kindled in some way, availed himself of the energy of the sun stored in the burning material. When he carried a bundle of branches to his cave and burned them there, he made use of the sun's stored energy transported from one to another locality. When he set sail to his canoe, he utilized the energy of the sun applied to the atmosphere or the ambient medium. There can be no doubt that the first is the oldest way. A fire, found accidentally, taught the savage to appreciate its beneficial heat. He then very likely conceived of the idea of carrying the glowing members to his abode. Finally he learned to use the force of a swift current of water or air. It is characteristic of modern development that progress has been effected in the same order. The utilization of the energy stored in wood or coal, or, generally speaking, fuel, led to the steam-engine. Next a great stride in advance was made in energy-transportation by the use of electricity, which permitted the transfer of energy from one locality to another without transporting the material. But as to the utilization of the energy of the ambient medium, no radical step forward has as yet been made known.
The three ways to obtain energy;
- using material in which energy is stored,
- transporting energy or
- using the energy present in our surrounding medium.
The ultimate results of development in these three directions are: first, the burning of coal by a cold process in a battery; second, the efficient utilization of the energy of the ambient medium; and, third the transmission without wires of electrical energy to any distance. In whatever way these results may be arrived at, their practical application will necessarily involve an extensive use of iron, and this invaluable metal will undoubtedly be an essential element in the further development along these three lines. If we succeed in burning coal by a cold process and thus obtain electrical energy in an efficient and inexpensive manner, we shall require in many practical uses of this energy electric motors—that is, iron. If we are successful in deriving energy from the ambient medium, we shall need, both in the obtainment and utilization of the energy, machinery—again, iron. If we realize the transmission of electrical energy without wires on an industrial scale, we shall be compelled to use extensively electric generators—once more, iron. Whatever we may do, iron will probably be the chief means of accomplishment in the near future, possibly more so than in the past. How long its reign will last is difficult to tell, for even now aluminium is looming up as a threatening competitor. But for the time being, next to providing new resources of energy, it is of the greatest importance to making improvements in the manufacture and utilization of iron. Great advances are possible in these latter directions, which, if brought about, would enormously increase the useful performance of mankind.
Note that the ultimate results number 2 (obtaining energy from the ambient medium) and 3 (wireless worldwide transmission of electrical energy) are goals of the Wardenclyffe project.
This is where Tesla gives us the key that I mentioned in part 3:
Food stands for energy. And the next one is iron. That is, the next key is iron which stands for electrical energy as will become abundantly clear in the next chapter.
Stay tuned, much more coming your way.
