I don't think it is moon powered, I was teasing.
Fluids seek level because they are in a state of matter that assures it. A better phrase would be 'center of mass seeks level in 3 dimensions'.
When an ice cube melts in a glass, it changes from a solid to a fluid. The center of its mass seeks level in the 3 dimensions of the glass . 'Fluids seek level' is another way of saying gravity acts as though all of an object's mass is concentrated at the center, and fluids' ability to level, because of their state of matter, is evidence that gravity acts this way.
Gravity doesn't discriminate between states of matter. The math equation for gravity
(Fg = G (m1*m2)/(d^2)
where G=gravitational constant (6.67*10^-11Nm^2/kg^2)
only needs measurements of mass and distance (from centers of mass) to solve; it's the same equation for any state of matter, solid, liquid (fluid), gas or plasma.
The gravitational force of the moon and sun, in combination with the gravitational force and centripetal force of rotating earth, comprise the system that creates fluid tides rising and falling. In other words, tidal power is a gigantic co-gravity, Cp force, and to some degree, electromagnetically, powered "wheel" that would either cease to turn, or be much weaker, if the moon or sun or earth weren't contributing their force and energy to the system. In some other words, it is an open thermodynamic system that is open to 3 types of energy.
One of the fundamental reasons perpetual motion is impossible is that no system can be completely isolated from the rest of the universe. There is always some interaction; irreversible frictional conversions.
