Machine Element Innovation – Spinning Vibration Elongation(x,y,z,t) Absorbing Rock Layer

The idea is simple.

Looking at the road. I think there is a rock layer underneath. For vibration and engineering purposes. So from this. What other inventions could use rocks as a machine element.

What if you could increase performance of big electrical motors with a layer of ?small rocks. So when it rotates. I guess the stresses elongate the motor parts differently and there I think you can have a new machine element. The rock layer.
