Disney Makes Nikola Tesla’s Wireless Power Dreams Come True

Nicholas Say — Sat, 25 Feb 2017 19:57:08 +0000

It looks like the Disney company has made Nikola Tesla‘s dream of wireless power transmission a reality. At least on a small scale. Disney Research has announced that they have constructed a room that will allow small electronic devices to be powered wirelessly. In the same way that your smartphone uses wifi, this technology gives […]

“We’ll Prove Nikola Tesla Was Right,” Say Two Russian Physicists

Benji Jerew — Thu, 12 Jun 2014 20:36:38 +0000

In 1901, Nikola Tesla began construction of what came to be known as the Wardenclyffe Tower, which was supposed to be used for worldwide wireless transmissions. Wireless transmission is ubiquitous today. In fact, I’m writing this article from my laptop, transmitting via WiFi to my router. I am in the highlands of Perú, and this […]

Cartoonist Waxes on Tesla Model S, Wants to Build Nikola Tesla Museum

Benji Jerew — Thu, 15 May 2014 17:10:06 +0000

Calling Matthew Inman a “cartoonist” isn’t really fair, but the way he waxes on about his Tesla Model S goes much deeper than simple talking heads in the Sunday Intellectuals Funnies page. Matthew Inman runs The Oatmeal, and also runs a Tesla Model S, and we thank him for putting together an accurate portrayal of […]

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

Ovidiu Sandru — Wed, 16 May 2012 16:40:14 +0000

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 […]

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

Ovidiu Sandru — Tue, 04 May 2010 18:36:25 +0000

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

Mike Sandru — Mon, 27 Jul 2009 12:45:33 +0000

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 Generator – a Self-Sustaining Electricity Harvester

Ovidiu Sandru — Fri, 28 Mar 2008 18:22:24 +0000

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."

DIY Tesla Turbine From a Hard Disk

Ovidiu Sandru — Wed, 06 Feb 2008 14:18:28 +0000

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 […]

The Tesla Turbine

Ovidiu Sandru — Wed, 06 Feb 2008 07:33:23 +0000

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)

Ovidiu Sandru — Wed, 06 Feb 2008 07:28:27 +0000

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

Ovidiu Sandru — Sat, 02 Feb 2008 18:13:07 +0000

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 […]

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

Ovidiu Sandru — Tue, 29 Jan 2008 20:34:44 +0000

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 Free Energy Device – The Bifilar Coil

Ovidiu Sandru — Tue, 29 Jan 2008 20:31:51 +0000

Tesla’s 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. Most of the free energy devices in question have […]

[The following is excerpted from Peter lindemann’s longer essay, which includes a theory as to the reason(s) the promise of advanced energy technologies have not been developedand introduced into the market. Such “conspiracy theories” are discussed elsewhere]. In the late 1880s, trade journals in the electrical sciences were predicting “free electricity” in the near future. […]

How to Build a Tesla 4 Battery Switch

Ovidiu Sandru — Tue, 29 Jan 2008 18:24:59 +0000

Nikola Tesla invented a device containing 4 batteries linked in some order I will present, that the 4 batteries somehow recharged themselves. How is it possibile? That can’t be, you’ll say, since every science class taught in school denies there is any other law above the conservation of energy. Indeed. True as it can be. […]
