Navy’s New Railgun Can Hurl a Shell Over 5,000 MPH
April 9th, 2014Via: Wired:
The U.S. Navy is tapping the power of the Force to wage war.
Its latest weapon is an electromagnetic railgun launcher. It uses a form of electromagnetic energy known as the Lorentz force to hurl a 23-pound projectile at speeds exceeding Mach 7. Engineers already have tested this futuristic weapon on land, and the Navy plans to begin sea trials aboard a Joint High Speed Vessel Millinocket in 2016.

So, whatever could provide enough juice during battle would have no problem making fuel at other times:

Regular nuclear electric? Maybe those cold-fusion
experiments went better than we’ve been told.
Those ultra-capacitors from a few years back would be very useful for the gun:

But I haven’t heard anything about them for ages.
If they’re legit, the guns could be scaled down for portable use. Ammo packs of projectiles with a sealed and charged ultra-capacitor. They’d probably look very ‘Halo’. Bigger units mounted on vehicles and robo-dogs.
Oh. Looks like someone’s already had this discussion:
