Music made by electricity and air. No speakers or sound equipment.
In this clip, “the music that you hear is coming from the sparks that these two identical high power solid state Tesla coils are generating — there are no speakers involved.”
The Tesla coils stand 7 feet tall and are each capable of putting out over 12 foot of spark. They are spaced about 18 feet apart. The coils are controlled over a fiber optic link by a single laptop computer. Each coil is assigned to a midi channel which it responds to by playing notes that are programed into the computer software
Nightclub applications of this could be pretty cool.
