Gravity wheel of Mikhail Dmitriyev

[sm0ky2]

Wheel 3 is ideal gravity wheel. But how to realize it?

Wheel 3, appears to have the same issue as the other two...,
there is a vertical distance not recovered by the imbalanced leverage.
(see red lines I drew)

Where is the read line you drew? I cannot see.

For wheel 2, my idea is the weight at uppper right hand side can use a stationary motor fixed at upper right hand side (within the circle of wheel) push to the right and the weight at lower left hand side can use a stationary motor fixed at lower left hand side (outside the circle of wheel) to push to the right. All the weights are pivot supportted by one way bearing so when the weights pushed to the right will not turn back to the vertical position.

It can build a close loop system. A generator is driven by the wheel and the electric generated powers the two motors and a LED light. Do you think it is possible?

Hi all.
my first wheels are not nice =)
You can look 1st with russian language here: http://www.youtube.com/watch?v=h_RjuHgVZtY and read some english description and results here: http://hrlab.me/en/dmitriev-gravitation-wheel-replication-1/

My second wheel is bit more interesting (but also not working one).
I done english video also: http://www.youtube.com/watch?v=OZFbe2jeaCw , and more description at my website: http://hrlab.me/en/gravity_wheel_2/

For all models you can download stl/skp files to rebuild em by yourself.

P.S. i'm not native english speaker, and totaly not a writer, sorry.

Your second video shows at least if the weights are always at right hand size will make the wheel turn. However I think the friction at the wheel center support is two high and weight are too small. So the torque is not high enough.

ok,my color is a little dull, so I re-did the image #3, and made the red line darker.

its in all 3 pics, where the "h" is.   E = mgh <---- that h is important!!

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.
