First look at this photo:
In this second photo note the centers of gravity of the cylindrical weights that have changed and you are restricted, that is, belong to a closed profile of the previous one, you can continue until it becomes a
circular profile that has its center coinciding with that of the PVC disc.
In the end you get a conformation similar to this under:
with the calibration of the spiral springs of archimedes only in the point A you are obtained a perfectly circular arrangement in the way described above: it is clear that for adhering the bearing at that point, the spring must press a little more of the weight, otherwise the bearings on the center line in the left part they remain detached unless you use the backward spring that is with an impediment to pivot allowing especially in the second quadrant of the bearing support for a fall. But I do not need to adhere to all.
But if the calibration is done well the bearings remain in contact for the duration of the 360 ​​° rotation.
This method allows to unbalance the weight forces that belong to the first circle which has the center of gravity that coincides with its axis of rotation and, therefore, just a small offset to allow the perennial rotation.
In this case, the laws of thermodynamics do not work but they work the laws of kinematics and therefore the wheel is forced to rotate because it is as it were on an inclined plane of infinite length that is the center of gravity of the forces is always located on the right side of the point of support which is the central hub.
The thing is so simple that until you build the model we do not understand a bat.
Words fly, but the facts remain put his hand to friction does not say anything because the rolling friction of a small cushion is so low that we realize that just one centimeter of sbaricentramento to overcome these frictions.
This last idea is a collaboration with Mr. Calzamiglia that made me look like him had made him sbari - centering of the weights with a step stellar frame 2 with too many bumps.
The long experience of the spiral springs are the starting point that allowed me this idea, the simple design is the starting point that allows the success of the construction;
it should be noted that the object does not require any special skills
and even a willing guy manages to carry it out even if you build the coil springs alone. to understand how it is built the ALDO COSTA wheel there are very many details. Below is the concept:
the theoretical final speed is almost 6.2 revolutions per minute, but because of two turnovers comes less than 2 revolutions per minute, but in the end still runs.
In the bicycle wheel, there are no tipping efforts and then the number of wheel revolutions are amazingly high, especially with ceramic bearings with low rolling friction.
Also in electrical engineering it is possible to construct the magnetic induction motor with an 8 groups of super-magnets immersed in a plexiglass disc with torque system that enhances alone because of the induced currents up to that of the one bearing and air frictions do not get to look under regime as it is simple, but it comes from Korea and is patented.
this engine is defined as perpetual motion because they are the same coils arranged so that the -1-2- diametrically opposite and appropriately inclined of 20 degrees are the generatrices of the motorcycle as function as impulse generating induced current that goes to feed the other 6 left and right coils that produce drive torque increase until an equilibrium is established due to the rolling friction of the bearing and the surrounding air.
The 3 LEDs with their loop also light at low speeds and provide a vision of a surge current.

Hi Franco Malgarini,

Thanks, the torque enhancement with the magnets caught my eye. This is the Korean patent application there are also other versions of the same idea.

WO2016133353A1 - Augmentor for rotational force of motor

You can easily calculate the output energy of your wheels. Measure the vertical distance between the lowest and highest point for each weight, and multiply with the weight.
Then you can calculate how much energy you need to supply to raise the weight from bottom to top, then you will find the potential energy of that weight.
Now, calculate how much kinetic energy you will get out when the weight makes it turn from top tp bottom.

If you find any difference in energy input and energy output, you have done the calculations wrong.
Do you find no difference between energy input and energy output you are spot on, but no netto energy output.
Magnetic assistance will not help you in any way. They will, just like gravity, take as much as they give.
