Software is not the answer one needs to build a real unit.  A ratchet effect will be need to hold the lever from falling back as it passes the equal point.  An excelleration will occur in as the wheel comes down.

Here you have the file, if you want to try. Yes, a software simulation is not the answer but it's a "start".. Btw, the ratchet effect seems to me very complicated to realize, cause when the wheel rotate there would be a system for "relaxing" the ratchet and allow the the lever to falling freely.

Hello, I was curious about this work and I've replicate it with Algodoo. I've tried the version magnet-assisted (look at the draw made by mr. Dmitriyev). Results: the wheel doesn't rotate, cause the magnets effectively assists the wheel, yes, but also in the opposite direction.

BTW, that software is great!

  Andrea,
 There is something simple you can try with magnets. Have them at an angle.
It is possible when passing the magnet, it's field
is also passed. If so, shielding would not be needed.

What do you think will happen to the wheel then the magnets is suppose to repel the magnets on the wheel? The repel must neccessarily act force in the opposite direction of rotation in order to unbalance the wheel. Therfor you will not gain any extra energy. You could likely use a lever to mechanicly push the weights out of position instead of using magnets.

Yep.


It would be even more beautiful without that big ugly blue MULTI HORSEPOWER ELECTRIC MOTOR driving it.

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.

I've created a feature page on this here: http://peswiki.com/index.php/Directory:Mikhail_Dmitriev_Gravity_Wheel

Mikhail Dmitriev Gravity Wheel - This Russian inventor has been developing gravity-based power systems for years and says that the design has been widely replicated in Russia, even powering some houses. He says he has posted all necessary information to build the device, in which a small amount of power input generates much greater power output. (PESWiki; January 30, 2011)

I also created an animation.

I saw you have a 3D solid works design in your website. Have you build the working prototype?

It has merit,  a gravity wheel, a wheel of leavers is what I liken it, along with angular momentum has potential.  Pulling a heavy load staight up with one pulley vs say 3 or 4 is good example.  The old torque vs speed.  A few years ago on a wind turbine project that I worked on violated the Betz limit, the local Phd's said it was impossiable until they stuck it in their wind tunnel ... I laughed my ass off.

I think for this to work better one needs to use a round weight at the end like a bearing and then a magnet at a right angle at the outside of the wheel this will help pull the weight up past the outer edge of circumferance and then when the weight crests the gravitation plain pull it will simply drop.  I also do not see how an even number of unit will work better then an odd number. 

Just my 1 penny thought.

I think I will build a small one ... just cause it now intriques me and I don't have the money to replicate the noble gas engine.

Have you build a workable gravity wheel? I have no money to build it but I am very curious about it.

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?

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.
