- You're probably right, but perhaps we just aren't being imaginative enough.
- First, couldn't an aluminum or steel ingot survive this g-load without
- deforming too badly? I can think of a few peaceful uses for a whole bunch
- of these in orbit... Second, is there no alternative to a rocket burn for
- orbit stabilization? How about giving the ingot a lifting body shape with
- a very simple control, like a radio-controlled explosive charge that
- deforms a control surface when detonated? A satellite could precisely
- determine the ingot's orbit, then deform the control surface at just the
- right time during a skip off the atmosphere.
-
- I highly doubt that what I described would be economical, or even work at
- all. Still, it makes me wonder if we should write mass drivers off just
- yet.
