If we could somehow deliver 5 million amps for 2 milliseconds (10,720 coulombs) to a gram of water and also convinced the gas bubbles to move out of the way quickly (maybe spinning really fast?)
Idk how electricity works but resistance might be an issue. Also don’t know if the ions would move fast enough. Magnetic field might also be problematic.
This would obviously be horribly useless as it’s like the same amount of amps you need for a railgun but just to fire a normal ass bullet.
Numbers are just estimates cause I really have no idea how much gas and how fast you need to fire a bullet.
Now this would have the side effect of producing a really explosive gas combo so who knows that could be helpful too somehow.
This would take years of research to make but no one would do that both because it’s useless and probably not possible.
