Centrifugal inertia propulsion with magnetic control of masses position.

In this solution the masses never touch the external rim, which is only for connecting entire system to electric motor and for placing on roller bearings. I assume that this system can produce linear thrust by changing speed of rotation of the weights what is realized by using the stack of electromagnets and the permanent magnets in the bar between the weights and by the combination of switching of magnetic fields along the bar. The difference in location of each of masses is also important, because if the mass is passing a short way from the center of rotation it is generating small centrifugal force but if the mass is passing on the longer path from that center it is generating stronger centrifugal force. This can happen of course with assumption that the energetical requirements from the electric motor will be fulfilled by a proper electric current parameter which will have included the problems with eccentric mass location during the rotation of the rotor. The bar with masses consists of the stack of permanent magnets and it is oscillating inside the external to it electromagnets in both sides. Inside the permanent magnets there is non-ferromagnetic rod, and it is holding entire bar with ball masses in one piece. The electromagnets (here in orange color) are switched on to attract the permanent magnet bar up every time the bar is coming out from the horizontal position, what is happen two times on every whole turn of the device.

The device is equipped in eight roller bearings which are holding the bar on certain distance from the electromagnets, not too big to make unavailable two-way interaction between the electromagnets and permanent magnet bar and make available to oscillate the bar inside the electromagnets. 

If the bottom mass is reaching the bottom side of electromagnet stack in the situation of approaching the upper mass in the summit of turning loop, the system starts to give its inertial energy in the right up direction, what is resulting as linear thrust simply coming from the difference between two forces acting downward and upward. In fast rotation these forces are summing to constant linear up-aiming thrust, although the two different directions of acting.

This device should be used in paired or triple system of the same generators.
