- It's not a rail gun; it's some kind of gas gun. It's being built
- by one of the Energy Dept labs. It uses a really big piston to
- compress hydrogen gas which drives the projectile out the launch
- tube, which is mounted at a right angle to the piston. Gas is
- fed into the launch tube as the projectile passes by.
-
- The first attempt will be a test with a light projectile. If
- successful, the plan is to scale it up.

- Sorry, that's all I recall. I don't even remember where the
