Wireless Power Transmission Made Better by Old Electronics Principles and New Circuitry

NC State University researchers have recently implemented what is being used in radios for decades in wireless power transfer (WPT) receivers – the ability of the receiver to keep track of the transmitter’s frequency if the differences are really small. This could ultimately impact electric vehicle wireless power transfer systems by making them more efficient [...]

Japanese Researchers Extend Range and Efficiency of Wireless Power Transmission

Since researchers from the MIT first announced that they had a working prototype of a wireless power supply in 2007, Japanese companies (and not only) sought to replicate and even surpass MIT’s results.

Bladeless Wind Turbine Built by Solar Aero, Inspired by Nikola Tesla's Invention

Remember that Tesla turbine we wrote about two years ago? Or the Tesla turbine made out of a hard drive? Nikola Tesla patented these turbines back in 1913, but he wasn’t able to build them properly because the metals he could use at that time didn’t have the right thickness and quality.

Tesla's Wireless Power Transmission Reinvented by Witricity

Eric Giler, chief executive of US firm Witricitywireless, talks about a new system that can deliver power to devices without the need for wires. The new system exploits simple physics principles and can be used to charge a range of electronic devices over several meters.

Tesla’s Self-Sustaining Electricity Generator

Before going into the details of this invention it would be worthwhile to have an idea of how any generator, even in theory, could be capable of producing a self-sustaining current. This has been clearly explained by Walter M. Elsasser in a Scientific American article (May 1958) titled “The Earth as a Dynamo.”

How To Build a Tesla Turbine From a Hard Disk Drive

Disks At first I tried using CDs because of their large surface areas, but they didn’t hold up too well under the milling machine. I also had a stack of platters from old and defective hard drives, but I didn’t know if the smaller diameter disks would work as well. One problem I ran into [...]

John Bedini's Scalar Wave Battery Charger

It happened on a Saturday night on the Bill Jenkins Show. I was invited to speak between the Dodger Baseball game and the news. The show had about one hour remaining to the end at 12:00 midnight. Bill Jenkins knew nothing about what I was going to talk about that night. The time came for [...]

John Bedini’s Cigar Box-sized Tesla Switch – How To Build It

John Bedini was invited to speak at the Tesla Centennial Symposium in Colorado Springs, CO, on August, 11, 1984, The symposium honored the 100th anniversary of the arrival of Nikola Tesla in the USA, and was sponsored by the Tesla Committee, by the Institute for Electronic and Electrical Engineers (IEEE), Pikes Peak Section, and by [...]

The Tesla Turbine

Nikola Tesla created an engine design nearly 100 years ago that is as much as three or four times more efficient than the combustion engine design that has dominated for reasons other than science.At the time of his invention around 1909, Tesla was able to demonstrate a fuel efficiency of 60% with his bladeless turbine [...]

The Tesla Oscillator (aka Earthquake machine)

Nikola Tesla is primarily thought of as an electrical genius, but he also was responsible for a number of mechanical devices. One of the most notorious of these was his “Earthquake Machine” otherwise known as the Tesla Oscillator. The machine which Tesla tested was small, around seven inches long, and weighing only one or two [...]

Tesla's Unipolar Dynamo working principles

Tesla’s design varied from that of Faraday in two major ways. First, he used a magnet that was bigger in diameter than the disk so that the magnet completely covered the disk. Second, he divided the disk into sections with spiral curves radiating out from the center to the outside edge. In the Faraday unipolar [...]

Tesla’s Radiant Energy System

Brooklyn Eagle July 10, 1932 Nikola Tesla states: 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 [...]

A few things about the Tesla Coil

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit’s typical components were unknown at the time, but its design and operation together achieved unique results”not the least because of Tesla’s masterful refinements in construction of key elements, most particularly of [...]

Tesla’s Free Energy Inventions Supressed

Free energy suppression is a conspiracy theory claiming that certain special interest groups are suppressing, or have suppressed in the past, technologies that would or could provide energy at reduced costs, reduced pollution output, or would or could reduce the energy consumption of various devices. Groups most often implicated in such activity are the oil [...]
