Build Your Own Gauss Pistol
BdosError writes "A Russion software developer has developed a homemade Gauss pistol. It's not very powerful yet, but as a proof of concept, it's interesting. Nice, non-chemical slugthrower that should appeal to fans of Science Fiction and related games, like Traveller and many others."
Ahh, yes, silence, nice concept. Nice but flawed. Once the power is ramped up to achieve more than paint gun power, the noise will come along with the bullet speed, getting several magnitudes louder if the bullet can actually be made to move at or above mach 1. That part of physics cannot be made to go away unless one could build a soundproof pipe for the bullet to travel inside of on its way to the target.
And that is going to be a hell of a lot harder to hide than the gun itself.
