Wirelles power transfer using tesla coils

Project description

This project is a descendant of my SSTC1, after it was retired. This coil’s purpose is to run with it’s breakout suppressed, and demonstrate the concept of wireless power Tesla himself used to work on in his time.

I’m still in process of searching for more videos and pictures of this project, after it was upgraded. Apparently all the pictures from the Tesla museum site have been lost, and I don’t have the model at home any longer. It also seems that I never even drew schematics for much of the circuitry, and will need to hack them up together before I can put up a sensible project page. Stay tuned!

The following schematic illustrates the basic idea of capacitively coupled wireless power transfer, as I implemented here:

While the demonstration was cool, the efficiency again wasn’t anything spectacular (10-20%, depending on distance) and heating in the secondary coil forced me to keep the runs short.

A video of me performing some fun tricks with this coil. Many people have asked whether normal incandescent bulbs can be lit remotely by a Tesla coil – yes they can! It’s ability to set things on fire at a distance is also quite startling!

I only found some pictures of wireless power being demonstrated by original SSTC1, before it was rebuilt!

  1. Marko, great stuff! I own a classic 2″ coil, took me 10 months to complete, worked from first light nice streamers at least 1 to 1.5m long, quite spectecular, on facebook is the whole story, Tesla coiler SA visagie som
    e videos on youtube “wizzmam” would like to ask you of any other cool experiments with a coil? I use a 4 mot stack with weldind rod ballast, core adjustable, pulls 13 amps from 230 mains. Pfc caps on trannies.
