Blowing up random stuff

I finally got some time to build switch that can handle near 100kJ wayyyy over 100kA discharges.

Here is couple test shots. Due to fire and smoke hazard next time i will be playing outdoors with moar energy. Also there is capacitor upgrade coming and maximum energy storage will rise from 83kJ to about 110kJ.

Which voltage was that? This is a electric arc and not a direct short circuit, correct?

@Prometreus

22kJ shot was 2000 Volts and 50kJ shot 3000 volts.

Both shots were dead short circuits at first (capacitor bank output bridged with 1½mm^2 copper wire) Huge current from discharging capacitors turns copper wire into copper metal/oxide vapour which expands very rapidly. Result is rown-black-green smoke and burn marks :)

@Kizmox Ah that makes things clear :) I wondered why the currend is that high any way! Let me guess: The current is calcualted and not measured :) The capacitors must have an extreme low internal resistance to survive this torture. ...

@Prometreus

Actually i have measured these disches and they are real :)

And yes, these capacitor are very low ESR/ESL inverter grade electrolytics

My god that is a violent bank! I approve

Whats the name of the music?

Nice vid!

Nice!! I like how even the cables break things when you dump that much energy into things
