Gravity wheel of Mikhail Dmitriyev

[sm0ky2]

The weight from 12 o'clock to 3 o'clock cannot be supported by a stationary platform otherwise the gravity force acted on the wheel is zero. I saw Mikhail Dmitriyev use motor to push the weights to the right hand side at about 1 o'clock but after that they turn back to vertical position again. I think a one way clutch is needed to maintain the weight position at right.

The platform at after 6 o'clock can be used to turn the weight to the right again and support the weight as the gravity force in this region has reverse effect to the wheel clock wise turning.   

The point im trying to emphasize here is that E = mgh, regardless of the mechanical method used to "lift" the weight.
motors, relays, etc. This energy must still be applied to perform the work. And in each example, the weight lifted and the weight falling is the same. Resulting in a net energy of 0. Any losses do to friction, heat, wind resistance, etc. further detracts from the driving force.

But if magnet to lift the weight at 7 o'clock, the wheel will be unblanced. Then it can rotate.

Permanent magnets, perhaps - if they can be arrange such that the force vector is not counter to rotation.

electromagnets will waste energy
