But if the shell is instead constrained inside a straight tube, the tube would experience a lateral force and if allowed to move
against an energy absorber, one could extract that energy.

Even an artillery shell that has its apparent path diverted by the coriolis effect is not given extra energy from the earth, but instead travels in a free path. The earth rotates out from beneath the original aim point. A similar process must be happening to the air flowing due to wind.

If the RAR system is getting energy from the rotation of the earth it is doing something with the conservation of angular momentum that current physics cannot explain, and I would not expect that to come from a system consisting of 50 tons of ironmongery.

The corriolis force means that the convection currents do not just go in a north-south direction but swing to the east or west. Given all this, at least some of the energy that drives a windmill sitting in the trade wind comes from solar energy. I suspect that trying to work out what proportion (if at all) comes from the spin of the earth is an interesting maths/physics/engineering question. I shall pass it to my son to look at.
