Here are the suppressed inventions of Nikola Tesla all in one place rendered in clear English and in 42 illustrations. Tesla was famous at the turn of the century for inventing the alternating-current system still in use today. But his later inventions, documented in some 30 U.S. patents between 1890 and 1921, have never been utilized as Tesla intended despite their obvious potential for advancing in fundamental ways the technology of modern civilization. Among these lost inventions: the disk-turbine rotary engine, the Telsa-coil electric energy magnifier, high-frequency lighting, the magnifying transmitter, a radical high-power radio, wireless electric power, and the free energy receiver. (This is the original and the classic. Accept no pot-boiler imitations, however "fantastic.")

The other "classic," third edition, countless printings, still selling

. Invented by Nikola Tesla back in 1891, the Tesla coil can boost power from a wall socket or battery to millions of high frequency volts. In this booklet, the only systematic treatment of the Tesla coil for the electrical nonexpert, you'll find a wealth of information on one of thebest-kept secrets of electric technology, plus all the facts you need to build a Tesla coil on any scale. And you can build one out of everyday stuff; the coil shown features a beer-bottle capacitor. A well-tuned coil's output is harmless but can perform amazing tasks. Light your home, farm, or ranch at a fraction of the usual cost. Disinfect water. Build a powerful radio transmitter. Includes an introduction to the megapower Tesla coil called the magnifying transmitter and how Tesla envisioned its use for wireless power and global communications.

Son of Tesla Coil
Build a Tesla Lighting Plant.

We've thrown lots of sparks, but is that all Tesla had in mind? In this sequel to the classic Tesla Coil, we venture into the utilitarian Tesla. In clear English and 40 illustrations, we ponder the questions: Can Tesla coils do real work? Can a Tesla coil power a practical

alternative fluorescent lighting? Build a "third generation" Tesla coil. Discover the magic of oil immersion, of close coupling, and of precise pulsing. Learn how to drive a Tesla coil from low-voltage battery power. See how the new neon technology can be adapted for Tesla off-the-shelf. Build a solid-state pulse generator and a Tesla lighting plant. Then hook up your ammeter and see what it says about Tesla efficiencies. Can battery-powered Tesla technology aid us in the next big blackout? Will Tesla be the next big step forward in home power?

Magnetic Amplifiers
Another Lost Technology by the U.S. Navy (1951)
edited by Trinkaus.

First came the vacuum tube, then the transistor, right?. Not really. In between there is another lost entity. Electronics engineers of the 1950's believed the rugged little magnetic amplifier was going to replace the fragile vacuum tube in all its functions under a

megacycle. Originating in the USA but adopted and developed by the Nazis for the V2 missile, the mag amp after WWII found a clique of boosters among US electronics engineers. This document, unusually passionate and well written for a military tech manual, is their promotional brochure. Evident today only in some motor-control and power-supply regulator applications, the mag amp not only can regulate but can magnify, modulate, switch, pulse-generate, invert, convert, multivibrate, phase shift, and multiply. Mag amps require zero maintenance, can be made indestructible and EMP-proof, and can handle up to 200,000 amperes. Modulate your Tesla coil with a mag amp. This booklet has been completely reset and redesigned for economy and readability. Also see: Magnetic Amplifiers Bibliography

Radio Tesla
The Secret of Tesla's Radio
and Wireless Power.

Who owns the ether? In clear English, 66 illustrations, and a minimum of math, this booklet details the radical radio technology of Nikola Tesla. Early elemental wireless devices like Tesla's and many others shown in this booklet are fascinating and worthy of study because they remind us that powerful radio technologies can be so simple and accessible. Here is Tesla's peculiar radio in the context of the conventional. Modern radio took a lot from Tesla, but what did it ignore? Tesla's potent transmitter produced high-voltage, sudden-pulse disturbances of low frequency conducted through the ground as effectively as through copper wire. His wireless power works on the very same principles. Also in these pages: spark reconsidered, grounding rediscovered, low frequency revived, lament on solid state, underground radio, license-free radio, the suppression of amateur radio, carrier-current radio, radio-free energy...

Tesla: The True Wireless
Everything You Know is Wrong

By Nikola Tesla (1919), edited by Trinkaus. In Tesla's own words and in 20 illustrations, this is the inventor's final published statement on how radio, at the radical, really works. What is the true wireless?

Tesla says the orthodox Hertzian radio we've been taught is a "fiction." He insists that the amount of energy that can be transmitted is "billions of times greater" than conventional radio would allow. Can we transmit electric power to our homes and workplaces without wires? Can the unsightly and fragile grid come down? Tesla says Yes. This article of 1919 has been completely reset and redesigned for clarity. Includes an introduction by Trinkaus, explanatory notes, and information sources.

Magnetic Amplifiers Bibliography

By the U.S. Navy (1951).
A supplement to Magnetic Amplifiers.

The zealous authors of Magnetic Amplifiers appended this exhaustive 500-entry compendium, which lends itself to separate publication. Most of the citations are of patents you can still easily access. There are also citations of scientific and engineering journal articles, of military documents, and of procedings of the Institutes of Electrical, Electronics and Radio Engineers. Entries range all the way from the year 624 BC to 1951. A must for further research into the lost technology of the magnetic amplifier. Or you can just enjoy perusing these citations for a glimpse into a world of electronics now forgotten.
