so why does it work?

the bottles on the wheel all have the same weight of fluid in them.

by offsetting the fluid weights on the wheel there is no imbalance

of the wheel that would cause a sustained rotation.

so where does the force come from that causes a sustained

rotation of the wheel?

BR) at the bottom right the liquid mass moves closer to the center of rotation.

and while the mass is moving closer to the center of rotation the mass is moving

independently from the wheel and in the opposite direction of wheel rotation.

this movement of mass does affect the rotational energy of the wheel

because the mass is being pulled down by gravity.

and gravity causes a torque on the wheel in the opposite direction

of rotation.

this torque can be calculated using the mass of the fluid and its

distance from the center of the wheel.

as the liquid mass strikes the end of the bottle there is a rather

large force applied to the wheel in the opposite direction of wheel rotation.

so here we have two forces that are applied in the opposite

direction of rotation.

TL) at the top left the liquid mass moves further from the center of rotation.

and while the mass is moving further from the center of rotation the mass is moving

independently from the wheel and in the direction of wheel rotation.

this movement of mass does affect the rotational energy of the wheel

because the mass is being pulled down by gravity.

and gravity causes a torque on the wheel in the direction

of rotation.

this torque can be calculated using the mass of the fluid and its

distance from the center of the wheel.

as the liquid mass strikes the end of the bottle there is a rather

large force applied to the wheel in the direction of wheel rotation.

so here we have two forces that are applied in the

direction of rotation.

the results are ...

the impact of the fluid in the bottle at the top left imparts

the same rather large force equal to the force generated by the

fluid in the bottle at the bottom right of the wheel.

however because the impact at the top is further away from the center

of rotation than the impact at the bottom of the wheel

there is more torque applied by the impact at top left in the

direction of wheel rotation than the torque applied by the impact

at the bottom right in the opposite direction of rotation.

E=2-1 not Mc^2

the differences of the two torques generated by the

fluid moving closer and further from the center of rotation

will cancel each other out and will not add or subtract any

rotational energy to the wheel.

the wheel itself is balanced ...

the only forces that cause the wheel to rotate is

the impact forces as the fluid strikes the ends of

the bottles that are located closer and further from

the center of the wheel.
