Each capacitor is rated at 100,000 Amperes/shot for 300,000 shots(!). I'm now redesigning the system so that it can deliver up to 24,000 Joules, or about 17,800 foot-pounds of energy per shot. This is about the same energy as dropping a one ton weight from a height of 9 feet!
Power capacity is all down to size. There must be a theoretical limit based upon size and area alone of any comparable cell or cap. A big battery will always carry more capacity.
Ouch this guys is crazy....
To tired to investigate more.
E = .5*.00006*(12,000)^2 = 4320 J ~ 1.2 Wh.
Lol. I wonder what the price is, though. At three dollars a piece, it might be worth it - now I just need 2000 of them.
