More on the Z-pinch
In the article's picture of the test rig, you'll notice very large hex head nuts on the back of the engine. Real deep-space engines require big nuts, and that's why the Air Force seargent at Stargate Command is always walking around with the big crescent wrench.
Speaking about fasteners, who ever came up with pop rivets should have been hanged.
