No,it spins metal balls at insanely high RPMs within the weapon
and then eject them towards the target.
But hmm... I suppose the weapon has to be constantly on before it
is used... for it takes time to spin the balls up to speed (just
like how there is a slight lag before electrically powered miniguns
are fired)... so it's application for individual infantry weapons
may still be some ways off. But it will work good on the mounted
role though.
The only sound would be a lot less then normal firearms, and the
only sound from the projectiles will be from the sonic boom as they
break the sound barrier.
