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...

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 Generator – a Self-Sustaining Electricity Harvester

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

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...

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...
