Nikola Tesla World System for Wireless Energy Transmission

Nikola Tesla’s Transmission Systems

My previous writings have laid the foundation needed to understand this article, in which I will give a brief overview of how the current power grid evolved, and how Tesla planned to radically change this. Evolution of electric power transmission In the beginning there was direct current, or DC. However, there was not one single […]

History of the Tesla Coil and its geometries

History of the Tesla Coil and its Geometries

The first time I ever heard about a Tesla Coil, was actually while playing the video game Red Alert during my teenage years. In the game, the coil was a powerful weapon which shot massive bolts of lightning at the enemy. Shooting big sparks is actually the main association people have with the Tesla Coil, […]

Tesla Hairpin Circuit Stout Copper Bars Replication

Tesla Hairpin Circuit Replication & Experimental Results

After more than a year of research and development, I am excited to finally share my Tesla Hairpin replication and experimental results! I share things that worked, and things that didn’t work, as well as why. This article also contains a detailed parts list, so you can easily replicate my setup and experiments. This article […]

Impedance, the Skin Effect, and how they apply to Nikola Tesla

Impedance, the Skin Effect, and their Implications in High Frequency Circuits

Many of the famous experiments Nikola Tesla performed involved high frequency alternating- or impulse currents. At these high frequencies, something interesting happens: these rapidly vibrating currents pass with great difficulty through a seemingly low resistance conductor. This effect is caused by impedance, or the opposition of a conductor to the flow of alternating current. This […]

Lecher Lines: A Translation of the Original Paper by Ernst Lecher

While reading up on Nikola Tesla‘s Hairpin circuit, I constantly came across people saying that Tesla’s circuit was identical to Lecher Lines, invented by the Austrian physicist Ernst Lecher around 1890, which was an apparatus used to measure the wavelength of high frequency electric waves by creating standing waves on two parallel wires, and then measuring […]

Tesla air quenched spark gap replication

Tesla Air Quenched Spark Gap Replication

In a previous post I performed a detailed literature review on the various types of spark gaps Tesla employed in his experiments. My motivation for that research was that I am trying to replicate Tesla’s stout copper bars, or  ‘hairpin’, circuit, and I wanted to figure out which type of spark gap he was most […]

Nikola Tesla Spark Gaps

Tesla’s Spark Gaps: A Literature Review

Spark gaps play a central role in many of Nikola Tesla’s devices, most prominently in the circuits powering his famous Tesla Coils. In its simplest form, a spark gap is nothing more than two electrodes with some space in between through which an electric spark passes when the voltage in a circuit reaches a high […]
