Mass driver I believe is used to describe "gauss guns" or "coil guns", where you have electromagnets that pull a permanent magnet shot along.

Railguns use current flowing straight though. Coilguns have very bad efficiency or something and are hard to switch, I think that's why railguns get more attention. Some guy built some railguns and coilguns himself, and I think he used a power distribution (yep, the kind that switches the power grid) solid state switch to achieve a good 70000A. But railguns have the issue of rail erosion while coilguns don't have wear issues.

lol, BAE systems... one of the developers of the gun, is a british company

damn cool thing though lol

There's a lot of other cool stuff in development now beyond that. Check out the various systems they are developing for space exploration, solar sails are neat, as is the space elevator or some of the other crazy ideas of how to break out past the atmosphere. Railguns have been around a looooong time but as others said above they are just now starting to reach the point where they might be capable of being deployed.

That's the latest word from an acquaintance at Dahlgren. I'm wondering if they's solved the gauge reading issues for the reactors on the ships.

They have an office building near me; I'm located right near a huge East Coast NAS.
