Tesla Transformer Builders

Project goal

To build updated MOSFET driven thermoelectric DC Tesla coils that turn ordinary current into "wattless" energy - "Tesla Transfomers."

Underlying theory

Article:Tesla DC Thermoelectric Coils

Turning on a low ohm primary circuit thousands of times per second enables us to tap "discharge current" / coupled current via a constantly collapsing magnetic field. This is then fractionally distilled, via a 7 ohm steel based secondary, to leave just the gaseous part, pure "wattless" energy. This is a two stage process. This basic theory may be refined as data is shared.

Secrets of Cold War Technology

Through successive experimental arrangements, Tesla discovered several facts concerning the production of his effect. First, the cause was undoubtedly found in the abruptness of charging. It was in the switch closure, the very instant of "closure and break", which thrust the effect out into space. The effect was definitely related to time, IMPULSE time. Second, Tesla found that it was imperative that the charging process occurred in a single impulse. No reversal of current was permissible, else the effect would not manifest. In this, Tesla made succinct remarks describing the role of capacity in the spark-radiative circuit. He found that the effect was powerfully strengthened by placing a capacitor between the disrupter and the dynamo. While providing a tremendous power to the effect, the dielectric of the capacitor also served to protect the dynamo windings. Not yet sure of the process at work in this phenomenon, Tesla sought the empirical understanding required for its amplification and utilization. He had already realized the significance of this unexpected effect. The idea of bringing this strange and wondrous new phenomenon to its full potential already suggested thrilling new possibilities in his mind. He completely abandoned research and development of alternating current systems after this event intimating that a new technology was about to unfold.

The effect could also be greatly intensified to new and more powerful levels by raising the voltage, quickening the switch "make-break" rate, and shortening the actual time of switch closure. Thus far, Tesla employed rotating contact switches to produce his unidirectional impulses. When these mechanical impulse systems failed to achieve the greatest possible effects, Tesla sought a more "automatic" and powerful means. He found this "automatic switch" in special electrical arc dischargers. The high voltage output of a DC generator was applied to twin conductors through his new arc mechanism, a very powerful permanent magnet sitting crosswise to the discharge path. The discharge arc was automatically and continually "blown out" by this magnetic field.

Imperative toward obtaining the desired rare effect, the capacitor and its connected wire lines had to be so chosen as to receive and discharge the acquired electrostatic charge in unidirectional staccato fashion. The true Tesla circuit very much resembles a pulse jet, where no back pressure ever stops the onrushing flow. Electrostatic charge rises to a maximum, and is discharged much more quickly. The constant application of high voltage dynamo pressure to the circuit insures that continual successions of "charge-rapid discharge' are obtained. It is then and only then that the Tesla Effect is observed. Pulses literally flow through the apparatus from the dynamo. The capacitor, disrupter, and its attached wire lines, behave as the flutter valve.

Actual calculation of these discharge ratios proved impossible. Implementing the standard magneto-inductive transformer rule, Tesla was unable to account for the enormous voltage multiplication effect. Conventional relationships failing, Tesla hypothesized that the effect was due entirely to radiant transformation rules, obviously requiring empirical determination.....

There was an attribute which completely baffled Tesla for a time. Tesla measured a zero current condition in these long copper secondary coils. He determined that the current which should have appeared was completely absent. Pure voltage was rising with each inch of coil surface. Tesla constantly referred to his "electrostatic induction laws", a principle which few comprehended. Tesla called the combined disrupter and secondary helix a 'Transformer"......

Tesla Transformers are not magnetoelectric devices, they use radiant shockwaves, and produce pure voltage without current. No university High Frequency Coil must ever be called a "Tesla Coil", since the devices usually employed in demonstration halls are the direct result of apparatus perfected by Sir Oliver Lodge and not by Nikola Tesla. The Tesla Transformer is an impulse apparatus, and cannot be as easily constructed except by strict conformity with parameters which Tesla enunciated.

Additionally, Tesla discovered an amazing phenomenon which removed all doubt concerning the true nature of energetic carriers at work in his apparatus. Tesla arranged a very heavy a U-shaped copper bus-bar, connecting both legs directly to his disrupter primary. Across the legs of this U-shaped busbar were placed several incandescent lamps. The arrangement was a very evident short circuit. The lamps were illuminated to a brilliant cold white light, while being shorted by a heavy copper shunt. Uncharacteristic of particulate current electricity, the bright but cold lamps revealed that another energetic current was indeed flowing through the "short-circuits".

Those who observed this experiment did not expected it to perform any function save the incineration of the disrupter circuit and possibly of the dynamo itself. Instead of this, witnesses beheld a marvel. The lamps lit to an uncommon brightness. In this simple demonstration, Tesla was illustrating but one of his many evidences. Electronic charges would prefer the least resistant circuit rejecting the incandescent bulbs for the copper path. The current in this situation chose to conform with a contradictory principle. Perhaps this was true because the currents were not electrical. Tesla repeatedly used this demonstration to evidence the "fractionation" of currents electronic, from currents neutral.....

A single question remained, the answer to which would provide him with the essential information needed to create a new technology. What so separated or 'fractioned" the diverse mobile carriers in his Transformer? It was the geometric configuration of the coil which inadvertently separated each component. Electrons were blocked from flowing through the wire length, while the radiant pulse was released over the coil surface as a gaseous pulse. Electrons should have drifted through the wire but, during each impulse period, were blocked by the line resistance. Thus, the gaseous mobile carriers were released to flow outside the wire, a pulse which travelled along the outer coil surface from end to end. Here then was evidence that electrical discharges were indeed composed of several simultaneous mobile species....

The original cylindrical coils were quickly replaced with cone shaped coils. With these bizarre geometries, Tesla was able to focus the gas-dynamic component, which now rose up like a jet of hissing white light from the coil tip. Tesla recognized that these discharges, while spectacular and awe inspiring, actually represented lost power. A power broadcast station had to evenly disperse the energetic radiance in all directions. Flame-like discharges caused the available power to undulate in space. This would produce unpredictable power drops at great distances. Consumers would not receive a reliable and consistent stream of energy. If his Power Transformer was to operate with highest broadcast efficiency, these flame-like discharges necessarily had to be suppressed. But suppressing these excessive aether jets proved problematic.

Harmonic frequencies

Subject to research. A base frequency is 4 KHz @ 5% duty. Go from there. Tuned frequencies will be much better.

Harmonic voltages

Linear series, in 120v increments i.e. 120V, 240V, 360V, etc.


Tim Harwood has proposed, and now outlined this project in detail, in addition to providing the base article / research. From past experience, Tim sees little point in simply lecturing a silent audience. The goal of open source projects is to encourage participation. If no-one is interested in re-creating DC coils, updated using modern electronics, then so be it. But this project at least provides the opportunity, and framework with which to do so, for anyone who is interested. Since all the concepts in this project are taken from lapsed patents filed in the 1890s, there are no restrictions on usage of the technology.



As always, all experimentation done at own risk.
