Russian inventor, Mikhail Dmitriev contacted me on January 28 to let me know about his gravity motor. He has apparently devised a mechanism whereby static gravitational pull can be harnessed to generate useful energy.

He has been working on various iterations over the years. A more recent one is shown to the right. In it, a small motor shown at about the 2-o-clock location spins a deflector mechanism clockwise. The deflectors push dangling weights to the right. Being on a counter-clockwise ratchet, this causes those evenly-spaced weights to stay outward long enough to cause the larger wheel to be imbalanced and thus turn clockwise.

The claim is that the energy required to turn the small motor is much less than the energy gained from the imbalanced larger wheel turning a generator. It reminds me of the system devised by British inventor, Bobby Amarasingam, the AOGFG, which he is in process of taking commercial. From what I can gather, AOGFG is further along in engineering market-ready iterations which can produce substantial power.

As I look at the photos and the animation of Mikhail's setup, it seems to me like it would be very easy to build. I could do it. A junior high student could do it from a kit.

He said that "Many enthusiasts in Russia have already made the device for home use." I asked him to give me an example of the input/output power, to which he replied:

A typical instance in the range 0.5 - 5 kW. The average size (1500 * 1500 * 700) mm. The average weight of 200 kg. Rotational speed (60 - 120) rpm. Design-folding. Costs here in the $(500 - 2000). This handmade mechanical part, without the electrical generator (output). Industrial production (assembly line) should be much cheaper. The most expensive items - overrunning clutches, Niodim strong magnets and output electrical generator (alternator).
Now, under my leadership, a firm builds an instance of an output power of 50 kW. This will be a multistage amplifier (4 stages). At the entrance of only 100 watts needed. An electric generator is only at the last output stage.

The PCT patent application describes this mechanism as a torque amplifier, but doesn't mention that more energy comes out than what is put in.

Mikhail said that he is NOT planning to take his device commercial because of the corruption in his country which would steal the technology away from him. Meanwhile, he says he has been helping many people to implement the technology into power generators they can use at home – sometimes powering those homes entirely.

I've approached him about helping him open source the technology, to expedite the process of validating, replicating, characterizing, optimizing, and improving the design for rapid worldwide deployment; with some revenue opportunities along the way in selling plans, kits, components, and finished units. I would ask up front here that anyone who goes commercial with this design remit a 7% royalty, a majority of which we at PES Network, Inc. will remit to Mikhail, retaining some to help administer this project and promulgate the knowledge, including providing income to the key players in the project, such as those who prepare the plans, do the translations, find local parts, etc….

Hi Sterling,
Yes, I'm willing to work with you to open source the technology.
This will be discussed in future correspondence.
I think that first you need to personally make sure that the device works as claimed. To do this, make a demo version directly at your workshop. This will be the most persuasive and credible evidence.
If you agree, then I'll send you a very simple scheme which you can make in just a couple of days. Compact desktop version (components only) will cost about $100.

Of course I told him yes.

Mikhail Dmitriev is a brilliant inventor who has helped me massively to get where I am with this design! He very kindly open sourced his design to us and I believe I was in the right place at the right time, back in February 2011.

I approached a local engineering company in February 2011. I met two engineers, one was a mechanical engineer and designer. They were interested in the device and gave me some ideas to further Mikhail Dmitriev's design.

I am a mechanic / autoelectrician / web designer / entrepreneur, not a designer and had never used Solidworks prior to March 2011. So I learnt how to use it by watching Youtube videos.

It is now my vision to bring to you what Nicola Tesla tried to do all those years ago. Tapping energy from the ambient environment and putting it to good use whilst teaching others how to do it.

I re-approached the same company at the end of September 2011 with these designs I had drawn. I was met by the same engineer but a different designer.

A few days after a two hour meeting where I demonstrated my apparatus for showing where the energy comes from, the 64 year old designer who has been in engineering since the age of 15 offered to do the design work for free in hope of future financial remuneration. He also came up with a number of design modifications which will greatly improve the efficiency. I believe this design uses neodymium magnets to tap energy from the ambient environment in a very clever way to move weights around, which cause a constant unbalance like a never ending set of tipping scales just like a water wheel, but using gravity instead of water.

Please watch this space for more news and videos of the model that will be manufactured, tested, then offered to you in kit form.

Also please join the group and get involved if you are able to.

Best regards,

Rotation due to deflection of weights_2

  • "The rotation due to deflection of weights. Motor 20 W easily overclocks wheel radius of 1300 mm with a mass of 30 kg to a speed of 120 rpm or more. In principle - to mechanical failure of the system. For pushing of the weights (in the desired point and in the right direction) requires a small amount of energy. Belt and gear on it is just not capable." (YouTube; October 10, 2010)

Alternate Deflector Mechanism

The following photos showing the use of a bicycle rim for the deflector assembly are from a June 22, 2010 YouTube video by Dmitriev. Title: "Implementation of solution n+2 for permanently unbalanced wheel"

This is apparently an attempt at self-looping. The video only shows still shots. Perhaps there were problems with the gear ratio and positioning of the deflector apparatus.

Magnet-Assisted Gravity Wheel

On Jan. 31, 2010, Mikhail provided the following diagram for building a benchtop demonstrator, with materials around $100.

February 12, 2011 memo: I've asked Mikhail three times if he or someone else has built the desktop version and if it has been shown to work, but he hasn't responded. -- Sterling D. Allan

Hi Sterling,
I made a drawing in AutoCAD, because it can see any fine details. In another format, they are simply not visible.
An alternate depiction of the cylindrical magnet Is not accurate. Because they must always be repelled by any relative displacements.
At the 1-2 o'clock position the magnets are shown being deflected to the right mainly from a rotating mechanical deflection (centrifugal force).
There is a mechanical block to keep them from going up more than 90-degrees from tangent; and another mechanical block to keep them from going less than 0 degrees from tangent.
This is shown in the figure (front view) as an external large circle and isometrics as small arched supports, located at the radius.
Diameter of the magnets in the magnetic deflector is shown bigger in sense that they must be more strong then each of 32 internal magnets.
All magnets should have the same length but different diameters. [Meaning the perimeter magnets are one diameter and the deflector magnets are larger, I presume. -- Sterling]
The diameter of the magnets in the deflector area should be larger. Deflector must push a weights (magnets) and create a partial "levitation" of the weights in the left side of the wheel.
This achieves a maximum torque of the system.
(to be continued)

It seems to me that with this clarification, we now have enough information to commence replication.


"I have a Useful Model Patent of the Russian Federation:
¹ 81775
International Application Number:
PCT / RU 2008/000725


  • TORQUE AMPLIFIER | pdf backup - Inventor: DMITRIEV MIHAIL FEDOROVICH; EC: F03G7/10 IPC: F03G3/00; F03G7/10; Publication date: 2010-06-03
The invention relates to mechanics, in particular to devices that work on the basis of a difference in moments of force in relation to an axis of rotation. The invention can be used as a device for enhancing the torque of different rotary devices which are actuated by manual traction, water, wind, permanent magnets and/or electromagnets. The invention can be used in places where there are no sources of electrical energy in order to provide an additional rotational moment of inertia to the rotors of water pumps and drilling rigs or to the drive of the rotating working members of other stationary or mobile machines or assemblies. The invention has the technical result of making it possible to maintain a prolonged moment of inertia during the rotation of a device without using electrical energy sources, which moment of inertia can be used for amplifying the torque of other devices by transmitting torque thereto. The claimed technical result is achieved in that a torque amplifier working on the principle of a difference in torque on opposite sides in relation to an axis of rotation and comprising spokes which are provided with a load and are mounted on a conditionally horizontal shaft is characterised in that, with the aim of increasing the resulting torque and providing for the stability thereof, each spoke consists of two parts which are interconnected by a unidirectional rotation mechanism, wherein in order to extend the spoke length and thus increase the resulting torque, a mechanism is used which straightens the spoke parts into a line on one side of the device and folds said parts on the other side of the device.

    The Shifting-Mass Overbalanced Wheel - From the 8th century to the present time inventors have sought to achieve perpetual motion by use of wheels with shifting weights. None have worked, but that doesn't stop people from using the same idea again and again, altering mechanical details, often with incredibly complex designs. (Museum of Unworkable Devices)
