I did some more calcs on this notion today, and rediscovered something I
found about ten years ago when this topic came up. If you are going to
build a tower for the purpose of having it support a linear motor, then one
will also drill a hole in the ground as far as it can possibly be drilled.
The hole is cheaper than the tower everywhere. This doesn't preclude a
tower, but the hole will be deeper than the tower is high most likely.
