The photo is of a linear motor built in 2001. It runs on Permanent
magnetic force only. In the total travel 1 wheel will rotate 1 1/2
turns in 6 wheel 9 total rotation are made as you know anything over 1
turn is free usable energy, when this motor was new it could run
slightly uphill
This is a simple proof of concept device that makes the point clear.

The drawings below are also non-electric
For every action there is an equal and opposite reaction: if the
reaction force is removed all there is action force of usable energy.
Drawing 13 shows a method of increasing and decreasing the magnetic
force to ferrous metals and the counter reaction force is in a reduced
input balance. about 1/50 of the total output power. This is the core
of how the EttCM technology works.
Drawing 20 and 21 are of a motor that is 2 full motors with 1 output.
Drawing 21 shows one motor that has 1 action force usable output with
no counter reaction.
The bottom half of the motor has a ferrous shield that allows the
separation of the attraction from the upper half.
You will notice that north and south are drawing the rotation movement
into the ferrous shielding. On exiting the shielding the magnetic
force is off allowing the counter reaction to the shielding to be
removed.
It is a simple system. timing is done with gears. friction is not an
issue because the power output is much the same as an electric motor.
Again this is a simple example of this technology just to show it
works. There are much better systems that can be Engineered.
Think about this as the steam age of magnetic motor machines.
