i think you misread..
tidal energy is generated on the Z axis (using current methods)
addressing your concerns(weather systems and thermoregulation) the Z axis is a non effector(wasted is the wrong term but im trying to find the right one)
Oh, yes I did.. Well so is there a link saying z axis energy doesn't contribute to temp regulation? Because if you slow z, you effect the horizontal movement of the wave.
Where did the z axis energy come from?
Where would it have gone if not to the energy extractor?
