Can we use one of them for home defense against thief?

Sure, you could have a capacitor bank in your bedroom and hook it up to the gun with a reel of 1 gauge cable

I can build you one, however I need 2000 of these capacitors. mouser.com/ProductDetail/EPCOS-TDK/B58033I5206M1/

It should provide about 2000 joules of energy. Where it gets interesting is you aren't limited by slow gunpower. You might be able to accelerate a 2mm diameter tungsten start at hypersonic speeds.

What about overpenetration?

>>31708424
vaporization at those speed the projectile might just shatter into dust on impact transferring all energy in the most glorious energy dump in the history of the world liquefying the area of impact and tearing the proteins and bonds holding the flesh together apart. As the wave expands outwards it pushes against the back eventually overcoming the elasticity of the skin and rupturing it in a huge spray of red

wonderful

leidenfrost would keep it in one piece. a 2mm tungsten rod would not expand in a human either, it would make a neat little hole

if you want a lot of friction and vaporization, the projectile has to be colder than a typical railgun projectile. vaporization is a waste of energy though, especially for soft targets. expansion is the most efficient way to cause damage

railguns are most interesting in the context of hard targets where penetration is king

It would stay together by momentum, its moving far too fast for leidenfrost to have any significant action

>>31709038

I think its more interesting in the air defense role personally.

If you got one in orbit maybe, in literally every other application a smart munition is about ten billion times better

>we could try shooting through this chobham-uranium-whateverthefuck-reinforced turret face of an Abrams / Challenger II with a giant overloaded railgun that breaks after 3 shots
>or we could just shoot a shoulder-operated Javelin at it that flies in a lazy curve and pens it at the weakest part of its armor

coolness =! efficiency
