This is definately the way to go, including for asteroid mining. We'll have to scale it up again, maybe a couple of times if our fiscal reports are to look good. Of course any positive annual statements would look good right now.

I was looking at the performance stats of Deep space 1 and it's engine could only generate 0.09 Newtons of thrust. 33.3 times the power of DS 1's engine! I wonder what a Megawatt class of engine would produce? Very impressive improvement for a second generation design. If they ever decide to send humans to Mars, I think an engine such as this would quell all talk of using chemical propulsion. Heck, I think this would be a good engine for an orbital transfer vehicle.

What is a "Hall engine" exactly ?
