This is a solid-state Tesla coil. The primary runs at its resonant frequency in the 41 khz range, and is modulated from the control unit in order to generate the tones you hear. So just to explain a little further, yes, it is the actual high voltage sparks that are making the noise. Every cycle of the music is a burst of sparks at 41 khz, triggered by digital circuitry at the end of a “long” piece of fiber optics. What’s not immediately obvious in this video is how loud this is. Many people were covering their ears, dogs were barking. In the sections where the crowd is cheering and the coils is starting and stopping, you can hear the the crowd is drowned out by the coil when it’s firing. This Tesla coil was built and is owned by Steve Ward. Steve is a EE student at U of I Urbana-Champaign. He and Jeff have been going to Teslathons, which is where they met. It’s been suggested that a good name for this coil would be the “Zeusaphone”. “Thoremin” has also been mentioned, though personally I think we need Theramin type inputs for that. To answer a few questions I’ve received, YES, someone did yell “Play Freebird!” after the first round of music.
I just got a mini-lecture from my high-school physics teacher about Tesla Coil and air-cored resonant transformer..but I just can’t understand what he says…I only understand the ordinary step-up or step-down transformer…
so, can anyone make it clear…what’s the difference between a tesla coil and an ordinary transformer?
NB:Do not use “extravagant” or “high-level” words…because my vocabulary is not that good, use “everyday” English if you can…

Tesla Coil?

When a Tesla Coil releases Ozone, is it really that dangerous? On that note, a plasma ball is a very small tesla coil, does that release ozone after a significant amount of time?

Great song, great album, great band….cheesy video 
I dont want to know how the levitation works but how does his tesla coil or apparatus works with just under 75 watts.All the tesla coils i seen work with mush more power than just 75 watts.
