Types of inertial propulsions.

Type 1 - System with swivel arms and rotating weights. In this system the weights are pushed ahead by connected with ball bearings arms and central cross rotor. The solution assumes of ex-center location of mass - longer distance from the center of mass on the top and shorter distance on the bottom of the device. The device should transform circular movement of the weights to linear motion. An external rim is collecting push force on the top more than on the bottom. System could work properly also if the weights would be pulled by rotor and swivel arms.

Type 2 - One rod inertial propulsion. System is consisting of only one moving element not counting hub with through hole for the rod and the shaft with rotor of the electric motor. 

Type 3 - Inertial propulsion with magnetic clutch.

Type 4 - Ex-center swing machine.

Type 5 - A simple inertial drive which is easy to do in home condition or in small workshop. The entire system is consisting of four steel balls, external ring, one cross pipe and electric motor. The main principle of operation of this system is that the balls have free space for extend outside cross pipe and they are rotating on asymmetric trajectory in vertical direction - ex- center location of cross pipe, so on the bottom they are hiding inside pipe and on the top position they are extending from them more so the centrifugal force is stronger on the top because the balls have more kinetic energy on the top as they are moving with greater velocity than on the bottom what is caused by less distance from the center of their rotation on the bottom than on the top. The balls have also enough space to rotate inside the cross pipe however some friction will be appearing in this system. This friction can be decreased using brass rings instead the bearings placed in each end of the pipe.
