@ Supergod,
 I also liked Mikhail's wheel, and for all the people saying that it doesn't work, I haven't seen a single replication by anyone to disprove it. I'm looking forward to seeing your results.

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.

Yeah, it looks cheap and easy to build, so why not?

Sorry for the offtopic, could you explain your turbine more, please?

Just a thought: If you're gonna use a magnet to assist the wheel, this magnet will allso assist the wheel in the oposite direction when the ball has passed the magnet.

Super God ... It is based on a ducted wind turbine.  I can not go into details at this time.

Low-Q - yes that is what I was thinking also ... one will need to use some magnetic shielding also other wise any help will be lost.  One could use lead for a half circle a sphere would be better ... this would serve as weight also.

I have started thinking on calculations also.  One needs to consider weight of the wheel etc and the amount of energy just needed to turn it along with anything that is attached to it.  And then gravity.

Another thought is an elipticle orbit ( think of a smot ).. look at planetary system it works on this principal because it needs to.  Earth's magnetisphere  place an import part.

I will build a round one first and then an oval one  .... if you can build up the speed and then sling shot it quickly to break free it should work.

 Very interestesting and in many of my simulations of the milkovic based  ideas, l see the elliptical orbit keeps popping up.

Magnetic shielding will not help here. The shield will also weaken the magnetic field which was suppose to attract the weight in addition to do the shielding part... Well, there is no way around gravity or magnets this way. The sum of forces will cancel out into nothing. Any weight that is limited to travel the same path, oval or circular, it is limited to the same difference in altitude, and therfor also limited to gain the same potential energy as the kinetic energy. These two will cancel out and not be able to provide excess force which possibly could do some work over distance.

Yes ran into this awhile ago ... gave it another read though.  Funny how science quickly forgets to relate items together .... they could have looked at why they put rifling grooves in a gun ... to spin the bullet for accuracy and distance.  This was proven way way back ... lol

But the degree's mentioned have great merit along with HD play.

I will beg to differ, the shielding is there to prevent the magnetic attraction from going through to the other sister weight ... when concentrating the magnetic beam to a point it will act as a pivot point and easy to tip and with ratching setup it can't go back which would then give the other magnet to pull up more. Try balancing 3 pencils, you can with 2, with 3 you are always trying to find a balance point the magnet is like the third pencil (A chat with David Hamel many years ago, which was never a spinning disk like some think but a vibrating one that could never find balance)  An eliptical orbit is also important as one wants to change the in a sling shot effect. 

Expanding on the theory ... Earth's gravity will also need to be converted to Frequency and then the secondary planetary will need to run beyond that ... I can't convert the Frequency until the final size and distance is measured. We also want to be able to use the Earth's stored inertia so the overall unit should be running to the east thus capitalizing on the Earth's speed spin  which can also be converted to Frequency.

The wheel should be a spoke wheel that way the energy is stored on the outside .

There are a couple of other things that I think can contribute also, but I will wait until I have it built and try it ... that way if it fails I don't look to bad ... and if it works then it make me look like a genius ...lol

The same design has been displayed on youtube before. It is not a selfrunner, but a funny toy :)

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.

Just a thought: If you're gonna use a magnet to assist the wheel, this magnet will allso assist the wheel in the oposite direction when the ball has passed the magnet.

BTW, that software is great!

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.

  Hi Andrea,
 I think it is what I mentioned to you on youtube about what you've built. If when a pendulum starts to swing, it eitheer lifts or stops the fall of another pendulum, then momentum can be conserved. This is beacause the pendulum passing bottom center can reach a greater height whille travelling less distance. Going with f = ma here.
 
 @Vidar, this guy has updated his video even though no one has claimed to have tried it and had different results.

  @Nickle, I think one thing people over look  when it comes to anything like SMOt is that there is a difference between pulling a weight and suspending it. If on the ramp upwards,the magnets increase in attraction (pull), if the weight comes to a drop off before the strength of the magnets can suspend the weight, then it is theorhetically possible to use magnets to assist in motion.
