Those are great, but 75 vDC is kind of low. Not particularly useful for much except maybe low voltage filtering.

What about creating a capacitor bank and then destroy stuff with it ? :devil:

^who doesn't NEED one of those! :evil:

I have two RIFA caps rated at 400 vDC, with 3300 uF of capacitance... just 4 of them would equal the same power as these capacitors.

Higher voltage = more current flow = high pulse current = better electromagnetic projects like coilguns, disc launchers, etc

BTW Does anyone know where i can buy a coilgun kit ? :thinking:

^Coil guns are easy to make. Just get a Puck SCR a bunch if caps, some wire a non metallic tube and that's basically it.

Yeah, after buying some of those 2600F supercaps @ 2.5V (8125J), the farad rating on those other caps just looks so small. I haven't found much use for them yet though.

My car battery can deliver 2.6 megajoules

The battery modules within the Eaton 9170+ UPS in my office have a combined 31.104 megajoules capacity...

Oh yeah? Well my gas tank has 1.2 GigaJoules :na:

I don't mean to brag, but...

1.21 Gigawatts!

My 2 18650's have about 100,000 joules,
but its just not the same is it...

 

[Fiddy]

its all about how quick you can dump it!
