Nikola Tesla’s Two Designs for Geothermal Energy

By. J. J. J.

Nikola Tesla recognized early in his life that humankind was quickly consuming the earth’s supply of forests, coal, gas and oil which we use for heat, light and motive power in our everyday lives. He realized that these methods were barbarous and wasteful, because eventually all the forests would disappear, and the coal, gas and oil fields would be exhausted. This was not just his own opinion, but a fact based off the geological investigations of his time which showed our fuel stores to be limited. He believed it was in the best interest of future generations that humans should find better means of providing energy to the global population.

On his 75th birthday, Tesla gathered members of the press together and proposed two new designs for geothermal electric power; one involved utilizing the different temperatures of the upper and lower levels of the oceans, and the second was based on the concept of using the heat from below the earth’s surface. The two ideas were not new theories by any means, but mere proposals made by Tesla to improve upon previous research that to date had not been economically viable to implement. With Tesla’s new designs, he assured that steam could be a financially feasible option to provide the world with clean and inexpensive electrical and mechanical energy sources.

It is well known that at certain depths of the oceans the water gets colder, and the reverse effect happens on land where the temperatures get warmer. Tesla’s plan was to utilize these effects by using vacuums and vacuum pumps to generate steam power. The significance of the vacuum is simple. When water boils it evaporates and creates steam. Science tells us that at sea level water boils at 212 degrees Fahrenheit. It also tells us that water boils faster at lower atmospheric pressures. For example, the higher in elevation water gets from sea level the boiling point becomes lower than 212 °F. Therefore, in a vacuum where there is little to no atmospheric pressure, water can be made to boil at the lowest temperatures. This similar behavior is shown in a device called a cryophorus, invented by William Wollaston. A cryophorus contains two vacuum bulbs interconnected by a tube and both partially filled with liquid water. The liquid in one bulb evaporates and is condensed in the other. If the dry bulb is rapidly cooled, say put in ice, the water condensed in the other bulb freezes and gives off steam.

The —cryophorus— is well-known as a scientific toy, exemplifying also the principle of refrigerating machinery.

Tesla’s oceanic and terrestrial plan was similar to this scheme except on a much larger scale. His adaption was to make use of the steam by inserting a turbine in between the two bulbs and connecting it to a generator turning the steam into useful energy. The steam from the turbine could also be cycled back and reused.

In the oceanic design, Tesla planned to dig a pipe down to the great depths of the ocean to collect cold water, and have another pipe close to surface level. His vacuum pump would draw water from both levels of the ocean—one towards his condenser and the other to his boiler. The boiler would boil water at surface temperature (58 degrees Fahrenheit), and the steam generated would be directed up an insulated pipe towards the turbine—spinning it into rotation. The steam exhausted by the turbine is then passed to the condenser where it meets with the cold water, and just like with the cryophorus, the water is condensed and the cycle repeats.

The oceanic scheme draws power from the depths of the ocean, utilizing the warmth of one layer, brought into contact with the cold of another, to operate great power plants. 

The terrestrial system acts in opposite manner. A deep tunnel would be dug in the earth and an insulated pipe, connected to the turbine at surface level, would be inserted. The steam from the depths would be lifted up towards the turbine. From the turbine the steam is discharged into a condenser. The condensed water flows by gravity through another insulated pipe reaching to a depth at which the temperature of the ground exceeds that of the condensate. The picture below explains the process.

The arrangement of the terrestrial power plant. Water is circulated to the bottom of the shaft, returning as steam to drive the turbine, and then returned to liquid form in the condenser, in an unending cycle.

Although these designs of Tesla never came into fruition, his ideas still remain. If you wish to understand Tesla’s concepts better you can read his article here:

Nikola Tesla explaining his “World Wireless System“ and how it differs from today’s radio and wireless technology.

(Pre-hearing interview with Nikola Tesla’s legal counsel in 1916 to protect his radio patents from the Guglielmo Marconi and the Marconi Company.)

Tesla:

“The idea was to put the coil, with reference to the primary, in an inductive connection which was not close—we call it now a loose coupling—but free to permit a great resonant rise. That was the first single step, as I say, toward the evolution of an invention which I have called my “Magnifying Transmitter.” That means, a circuit connected to ground and to the antenna, of a tremendous electromagnetic momentum and small damping factor, with all the conditions so determined that an immense accumulation of electrical energy can take place…

“I mean that you have to have in the circuit, inertia. You have to have a large self-inductance in order that you may accomplish two things: First, a comparatively low frequency, which will reduce the radiation of the electromagnetic waves to a comparatively small value, and second, a great resonant effect. That is not possible in an antenna, for instance, of large capacity and small self-inductance. A large capacity and small self-inductance is the poorest kind of circuit which can be constructed; it gives a very small resonant effect. That was the reason why in my experiments in Colorado the energies were 1,000 times greater than in the present antennae.

Legal Counsel:

“You say the energy was 1,000 times greater. Do you mean that the voltage was increased, or the current, or both?”

Tesla:

“Yes, both. To be more explicit, I take a very large self-inductance and a comparatively small capacity, which I have constructed in a certain way so that the electricity cannot leak out. I thus obtain a low frequency; but, as you know, the electromagnetic radiation is proportionate to the square root of the capacity divided by the self-induction. I do not permit the energy to go out; I accumulate in that circuit a tremendous energy. When the high potential is attained, if I want to give off electromagnetic waves, I do so, but I prefer to reduce those waves in quantity and pass a current into the earth, because electromagnetic wave energy is not recoverable while the earth current is entirely recoverable, being the energy stored in an elastic system.“

Legal Counsel:

"What elastic system do you refer to?”

Tesla:

“I mean this: If you pass a current into a circuit with large self-induction, and no radiation takes place, and you have a low resistance, there is no possibility of this energy getting out into space; therefore, the impressed impulses accumulate.”

Legal Counsel:

“Let’s see if I understand this correctly. If you have radiation or electromagnetic waves going from your system, the energy is wasted?”

Tesla:

“Absolutely wasted. From my circuit you can get either electromagnetic waves, 90 percent of electromagnetic waves if you like, and 10 percent in the current energy that passes through the earth. Or, you can reverse the process and get 10 percent of the energy in electromagnetic waves and 90 percent in energy of the current that passes through the earth.

“It is just like this: I have invented a knife. The knife can cut with the sharp edge. I tell the man who applies my invention, you must cut with the sharp edge. I know perfectly well you can cut butter with the blunt edge, but my knife is not intended for this. You must not make the antenna give off 90 percent in electromagnetic and 10 percent in current waves, because the electromagnetic waves are lost by the time you are a few arcs around the planet, while the current travels to the uttermost distance of the globe and can be recovered.

“This view, by the way, is now confirmed.  Note, for instance, the mathematical treatise of Sommerfeld, [*] who shows that my theory is correct, that I was right in my explanations of the phenomena, and that the profession was completely misled. This is the reason why these followers of mine in high frequency currents have made a mistake. They wanted to make high frequency alternators of 200,000 cycles with the idea that they would produce electromagnetic waves, 90 percent in electromagnetic waves and the rest in current energy. I only used low alternations, and I produced 90 percent in current energy and only 10 percent in electromagnetic waves, which are wasted, and that is why I got my results.“

[*] Editorial note: In 1909, Sommerfeld performed a theoretical analysis of the propagation of radio waves around the earth, solving for the problem of a vertical dipole over a finitely conducting homogeneous ground. He divided the expression for the resulting field into "space wave” and “surface wave” components. The surface wave part had nearly identical properties to a unique plane surface wave solution to James Clark Maxwell’s equations that had been identified by Jonathon Zenneck two years previously. The field amplitudes varied inversely as the square root of the horizontal distance from the source and decayed exponentially with height above the interface. [Sommerfeld, Arnold N., “Uber die Ausbreitung der Wellen in der drahtlosen Telegraphie,” Annalen der Physik, March 16, 1909 (vol. 28, no. 4), OP. 665-736.]

Legal Counsel:

“You spoke… about getting all of the energy from your transmitting into your recieving station by this method of yours. I do not understand how you can get all of it.”

Tesla:

“Oh, that is hardly true; I am speaking as a matter of principle. You never can get all the energy, because there is no such thing as a perfect apparatus.”

Legal Counsel:

“I did not mean it in that sense. I understand that there is, of course, always some loss, but my conception was that when you created a disturbance in the commercial condition of the earth at your transmitting station, that that extended out in all radial directions.”

Tesla:

“Yes, it did.”

Legal Counsel:

“And therefore how, at any given station, can you get more than a small fraction of that energy?”

Tesla:

“Pardon me you are mistaken… In my first efforts, of course I simply contemplated to disturb effectively the earth, sufficiently to operate instruments. Well, you know you must first learn how to walk before you can fly. As I perfected my apparatus, I saw clearly that I can recover, of that energy which goes in all directions, a large amount, for the simple reason that in the system I have devised, once that current got into the earth it had no chance of escaping, because my frequency was low; hence, the electromagnetic radiation was low. The potential, the electric potential, is like temperature. We might as well call potential electric potential. The earth is a vast body. The potential differences in the earth are small, radiation is very small. Therefore, I’d pass my current into the earth, the energy of the current is stored there as electromagnetic momentum of the vibrations and is not consumed until I put a reciever at a distance, when it will begin to draw the energy and it will go to that point and nowhere else.”

Legal Counsel:

“Why is that, on your theory?”

Tesla:

“I will explain it by an analogue.

"Suppose that the earth were an elastic bag filled with water. My transmitter is equivalent to a pump. I put it on a point of the globe, and work my little piston so as to create a disturbance of that water. If the piston moves slowly, so that the time is long enough for the disturbance to spread over the globe, then what will be the result of my working this pump? The result will be that the bag will expand and contract rhythmically with the motions of the piston, you see. So that, at any point of that bag, there will be a rhythmical movement due to the pulsations of the pump.

"That is only, however, when the period is long. If I were to work this pump very rapidly, then I would create impulses, and the ripples would spread in circles over the surface of the globe. The globe will no longer expand and contract in its entirety, but it will be subject to these outgoing, rippling waves.

"Remember, now, that the water is incompressible, that the bag is perfectly elastic, that there are no hysteretic losses in the bag due to these expansions and contractions; and remember also, that there is a vacuum, in infinite space, so that the energy cannot be lost in waves of sound. Then, if I put at a distant point another little pump, and tune it to the rhythmical pulses of the pump at the central plant, I will excite strong vibrations and will recover power from them, sufficient to operate a receiver. But, if I have no pump there to receive these oscillations, if there is nowhere a place where this elastic energy is transferred into frictional energy (we always use in our devices frictional energy – everything is lost through friction), then there is no loss, and if I have a plant of 1,000 horsepower and I operate it to full capacity, that plant does not take power, it runs idle, exactly as the plant at Niagara. If I do not put any motors or any lamps on the circuit, the plant runs idle. There is a 5,000 horsepower turbine going, but no power is supplied to the turbine except such power as is necessary to overcome the frictional losses.

"Now the vast difference between the scheme of radio engineers and my scheme is this. If you generate electromagnetic waves with a plant of 1,000 horsepower, you are using 1,000 horsepower right along – whether there is any receiving being done or not. You have to supply this 1,000 horsepower, exactly as you have to supply coal to keep your stove going, or else no heat goes out. That is the vast difference. In my case, I conserve the energy; in the other case, the energy is all lost.”

Legal Counsel:

“Mr. Tesla, does that not presuppose that the fluid must be incompressible?”

Tesla:

“I should say so, and electricity, whatever it is, certainly it is incompressible because all our experiments show that.”

Legal Counsel:

“Now, if you were giving that a name, what principle would you say was involved by which the radiation loss, where there is no receiver, becomes a gain or a conservation where there is a receiver?”

Tesla:

“There is no radiation in this case. You see, the apparatus which I have devised was an apparatus enabling one to produce tremendous differences of potential and currents in an antenna circuit. These requirements must be fulfilled, whether you transmit by currents of conduction, or whether you transmit by electromagnetic waves. You want high potential currents, you want a great amount of vibratory energy; but you can graduate this vibratory energy. By proper design and choice of wave lengths, you can arrange it so that you get, for instance, 5 percent in these electromagnetic waves and 95 percent in the current that goes through the earth. That is what I am doing. Or you can get, as these radio men, 95 percent in the energy of electromagnetic waves and only 5 percent in the energy of the current. The apparatus is suitable for one or the other method. I am not producing radiation with my system; I am suppressing electromagnetic waves. In my system, you should free yourself of the idea that there is radiation, that the energy is radiated. It is not radiated; it is conserved.”

“It should be borne in mind that electrical energy obtained by harnessing a waterfall is probably fifty times more effective than fuel energy. Since this is the most perfect way of rendering the sun’s energy available, the direction of the future material development of man is clearly indicated. He will live on “white coal.” Like a babe to the mother’s breast will he cling to his waterfall. “Give us our daily waterfall,“ will be the prayer of the coming generations. Deus futurus est deus aquae deiectus!”

Nikola Tesla’s World Wireless Manifesto

New York, January 1, 1904

I wish to announce that in connection with the commercial introduction of my inventions I shall render professional services in the general capacity of consulting electrician and engineer. The near future, I expect with confidence, will be a witness of revolutionary departures in the production, transformation and transmission of energy, transportation, lighting, manufacture of chemical compounds, telegraphy, telephony and other arts and industries.

In my opinion, these advances are certain to follow from the universal adoption of high-potential and high frequency currents and novel regenerative processes of refrigeration to very low temperatures.

Much of the old apparatus will have to be improved, and much of the new developed, and I believe that while furthering my own inventions, I shall be more helpful in this evolution by placing at the disposal of others the knowledge and experience I have gained. Special attention will be given by me to the solution of problems requiring both expert information and inventive resource – work coming within the sphere of my constant trailing and predilection.

I shall undertake the experimental investigation and perfection of ideas, methods and appliances, the devising of useful expedients and in particular, the design and construction of machinery for the attainment of desired results. Any task submitted to and accepted by me, will be carried out thoroughly and conscientiously.

“To the scientific experts, who are familiar, in theory and experiment, with electrical vibrations, the results here shown will, I believe, speak in eloquent language. But those readers to whom they are naturally less intelligible will ask: What are they good for, and what do they or have they demonstrated? To them it may be said that they have shown and proved among many other things: That ordinary currents can be transformed with high economy into electrical vibrations of any pitch, which are needed in many novel arts; they have shown that electrical energy in great amounts can be efficiently and safely transmitted without the use of wires to any point of the globe, however distant; they have furnished proof that the movements and operation of bodies and machinery carried by the same can be controlled from a great distance without any tangible connection whatever and with absolute precision; they have proved the practicability of a system of signaling without wires, not with the imperfect appliances as before attempted, which can not be tuned and are rendered useless by the play of a small induction coil, but by means of apparatus producing powerful oscillations and circuits in exact synchronism, with which it is impossible to interfere; they have shown that atmospheric nitrogen can be readily combined and valuable products manufactured, merely by the application of cheap water power, and that light, diffusive like that of the sun, can be produced with an economy greater than obtainable in the usual ways and with lamps that never consume.”

***NIKOLA TESLA’S INVENTION FOR COLLECTING THE UNLIMITED ENERGY FROM COSMIC RADIATIONS***


US Patent No. 685,957: Apparatus for the Utilization of Radiant Energy

To all whom it may concern:

Be it known that I, NIKOLA TESLA, a citizen of the United States… have invented certain new and useful Improvements in Apparatus for the Utilization of Radiant Energy…

It is well known that certain radiations–such as those of ultra-violet light, cathodic, Roentgen rays, or the like–possess the property of charging and discharging conductors of electricity, the discharge being particularly noticeable when the conductor upon which the rays impinge is negatively electrified. These radiations are generally considered to be ether vibrations of extremely small wave lengths, and in explanation of the phenomena noted it has been assumed by some authorities that they ionize or render conducting the atmosphere through which they are propagated. My own experiments and observations, however, lead me to conclusions more in accord with the theory heretofore advanced by me that sources of such radiant energy throw off with great velocity minute particles of matter which are strongly electrified, and therefore capable of charging an electrical conductor, or, even if not so, may at any rate discharge an electrified conductor either by carrying off bodily its charge or otherwise.

My present application is based upon a discovery which I have made that when rays, or, radiations of the above kind are permitted to fall upon an insulated conducting-body connected to one of the terminals of a condenser while the other terminal of the same is made by independent means to receive or to carry away electricity a current flows into the condenser so long as the insulated body is exposed to the rays, and under the conditions hereinafter specified an indefinite accumulation of electrical energy in the condenser takes place. This energy after a suitable time interval, during which the rays are allowed to act, may manifest itself in a powerful discharge, which may be utilized for the operation or control of mechanical or electrical devices or rendered useful in many other ways.

Figure 1 is a diagram showing the general arrangement of apparatus as usually employed.

Fig. 2 is a similar diagram illustrating more in detail typical forms of the devices or elements used in practice.

Figs. 3 and 4 are diagrammatical representations of modified arrangements suitable for special purposes.

…It will be found that when the radiations of the sun or of any other source capable of producing the effects before described fall upon the plate P an accumulation of electrical energy in the condenser C will result. This phenomenon, I believe, is best explained as follows: The sun, as well as other sources of radiant energy, throws off minute particles of matter positively electrified, which, impinging upon the plate P, communicate continuously an electrical charge to the same. The opposite terminal of the condenser being connected to the ground, which may be considered as a vast reservoir of negative electricity, a feeble current flows continuously into the condenser, and inasmuch as these supposed particles are of an inconceivably small radius or curvature, and consequently charged to a relatively very high potential, this charging of the condenser may continue, as I have actually observed, almost indefinitely, even to the point of rupturing the dielectric. If the device d be of such character that it will operate to close the circuit in which it is included when the potential in the condenser has reached a certain magnitude, the accumulated charge will pass through the circuit, which also includes the receiver R, and operate the latter…

“I have harnessed the cosmic rays and caused them to operate a motive device.

“Cosmic ray investigation is a subject that is very close to me. I was the first to discover these rays and I naturally feel toward them as I would toward my own flesh and blood.

“I have advanced a theory of the cosmic rays and at every step of my investigations I have found it completely justified.

“The attractive features of the cosmic rays is their constancy. They shower down on us throughout the whole 24 hours, and if a plant is developed to use their power it will not require devices for storing energy as would be necessary with devices using wind, tide or sunlight.

“All of my investigations seem to point to the conclusion that they are small particles, each carrying so small a charge that we are justified in calling them neutrons. They move with great velocity, exceeding that of light.

“More than 25 years ago I began my efforts to harness the cosmic rays and I can now state that I have succeeded in operating a motive device by means of them.

“I will tell you in the most general way. The cosmic ray ionizes the air, setting free many charges—ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor.

“I have hopes of building my motor on a large scale, but circumstances have not been favorable to carrying out my plan.

“I do not use the plan involving the conductivity of the upper strata of the air, but I use the conductivity of the earth itself, and in this I need no wires to send electrical energy to any part of the globe.”
