Holy ****!

Badass! I almost shit myself laughing when the higher pitched notes started Was not expecting that.

That's a faraday cage correct?

Yup. Faraday cage - sit inside the grounded metal shield, and the electricity will preferentially take that path, rather than roast your salty, juicy interior.

That looks like an awful expensive way to make music

LOL

I wonder what would have happened if this went wrong...

Pretty cool, I thought the Zelda one was better though.

how are they controlling the tones?

Not sure exactly, but it's just the frequency of the coil. Relatively easy to control using basic circuits.

They are solid state (SSTC) and the switching is usually done with isolated gate bipolar transistors (IGBTs). Basically you are turning it on and off real fast.

There are good designs (not true TCs) that make no spark noise at all and can reproduce music with high fidelity from about 100Hz-400kHz! The emitter is essentially a big plasma flame. I saw a demo in Hamilton (Bermuda) several years ago playing Moussorgsky's Pictures At An Exhibition and the tonal control and velocity was incredible! It was like the orchestra was floating 500 feet in the air and you could reach out and touch it! Supposedly it was a scaled down (!) demo using "only 5 megawatts of power".

I'm not sure what the breakdown was in power nor what kind of bass array was used because there was low registers (16Hz organ pedal notes) very clean and loud and I cannot fathom a flame producing those (although the fire was 60 feet tall). They were not answering my technical questions.

Holy shit!

You've heard of 60hz AC hum? Well you're not limited to just 60hz.

They could also put the wires in the hands of this guy...

I wonder if it would be possible to convert my current tesla coil to play music. Its not solid state.

Although, I've been wanting to build a mini table top tesla coil for some time. I'd like to try solid state with that one.....

Not easy and if you did it would not sound nearly as nice.

You were probably scaring them.
