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:

“The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter — for the future. His duty is to lay the foundation for those who are to come, and point the way. He lives and labors and hopes.”

Tesla was displaying the first alternating current motors that we still use today for power, and was also doing wizardry lighting wireless light bulbs like a fucking Jedi. The concept was so far ahead of its time that the people in the auditorium literally started panicking and running out the doors because they thought he was doing the devil’s work. His demonstrations would introduce the basic principles to the wireless transmission of energy we all use today in our everyday lives.

Curie is a hard second! She cool!

“Nature has provided an abundant supply of energy in various forms which might be utilized if proper means and ways can be devised. The sun’s rays falling upon the earth’s surface represent a quantity of energy so enormous that but a small part of it could meet all our demands. By normal incidence the rate is mechanically equivalent to about 95 foot pounds per square foot per second, or nearly 7,300 horse power per acre of ground. In the equatorial regions the mean annual rate is approximately 2,326 and in our latitudes 1,737 horse power for the same area. By using the heat to generate steam and operating a turbine under high vacuum probably 200 horse power per acre could be obtained as net useful power in these parts. This would be very satisfactory were it not for the cost of the apparatus which is greatly increased by the necessity of employing a storage plant sufficient to carry the load almost three-quarters of the time.

"The energy of light rays, constituting about 10% of the total radiation, might be captured by a cold and highly efficient process in photo-electric cells which may become, on this account, of practical importance in the future. Some progress in this direction has already been achieved. But for the time being it appears from a careful estimate, that solar power derived from radiant heat and light, even in the tropics, offers small opportunities for practical exploitation. The existing handicaps will be largely removed when the wireless method of power transmission comes into use. Many plants situated in hot zones, could then be operatively connected in a great super-power system to supply energy, at a constant rate, to all points of the globe.

"The sun emits, however, a peculiar radiation of great energy which I discovered in 1899. Two years previous I had been engaged in an investigation of radio-activity which led me to the conclusion that the phenomena observed were not due to molecular forces residing in the substances themselves, but were caused by a cosmic ray of extraordinary penetrativeness. That it emanated from the sun was an obvious inference, for although many heavenly bodies are undoubtedly possessed of a similar property, the total radiation which the earth receives from all the suns and stars of the universe is only a little more than one-quarter of one percent of that it gets from our luminary. Hence, to look for the cosmic ray elsewhere is much like chercher le midi dans les environs de quatorze heures [looking for lunch in the vicinity of fourteen o’clock]. My theory was strikingly confirmed when I found that the sun does, indeed, emit a ray marvelous in the inconceivable minuteness of its particles and transcending speed of their motion, vastly exceeding that of light. This ray, by impinging against the cosmic dust generates a secondary radiation, relatively very feeble but fairly penetrative, the intensity of which is, of course, almost the same in all directions. German scientists who investigated it in 1901 assumed that it came from the stars and since that time the fantastic idea has been advanced that it has its origin in new matter constantly created in interstellar space!! We may be sure that there is no place in the universe where such a flagrant violation of natural laws, as the flowing of water uphill, is possible. Perhaps, some time in the future when our means of investigation will be immeasurably improved, we may find ways of capturing this force and utilizing it for the attainment of results beyond our present imagining.”
