Is there anything more difficult to contrive than a gravity wheel?
Two things throw my perception of gravity out of whack..:
Terminal Velocity
And that crazy inverting gyro toy..
What is it with sickle shapes that seem to focus inertia? Or a spinning sickle 'dome' that wants to align with gravity and dis-obey inertia?
Wassup?
