Prove it. How much waste heat will the engine need to stand? All the
radiation heading toward the shield will be come heat. The pipe and wire
will heat up too.
Are you sure that will be all it takes to turn your relatavistic pion stream
toward the rear of the ship? The magnetic feild would have to at least be
strong enough to lift the 600,000 lb ship, since its the force transmiting
the thrust to the ship. Past that though it has to have more power to turn
the random pion stream.
Thats just off the top of my head.
