# inertial propulsion with gyroscope part 16

Going on small experiments to try to isolate some specificity of gyroscope, to better understand, and why not improve, the inertial propulsion with gyroscope.

On the video part 12 i made the seesaw system, but i was not very happy, because the opposite swing could be perhaps a mass transfer or a gyroscopic torque or both.

Then i relook at Eric Laithwaite lecture, where he placed the spinning gyro on the small Eifel tower on ice.

This experiment from Prof. Laithwaite was “debunked” by some students. And the motivation was to prove that on an air table, the device behave as it should in normal Newtonian physics. And they explain that the feet of the Eifel tower were stucked into the molten ice so the Laithwaite’s experiment was wrong.

Another youtuber “Jogglevision” also demonstrated this very bizarre effect on a asymetric suspended gyro, and he also implemented his video

with a theory named ” the Nitro’s first law” probably in some opposotion to M. Newton. But very interesting to open minded thinkers as i am.

So i could not prevent to redo this experiment. and i have noticed very interesting things.

1- when the gyro spins fast enough it seems that the application of its center of mass is no more in the middle of the gyro (CG) but is displaced along the shaft in direction of the pivot,and eventually,is situated passed the pivot. So the chariot does not move at all, even when the centrifugal force is acting in full on the dead mass of the gyro as for instance the steel and heavy axel.

2- when the gyro slows down, the center of mass of the gyro seems to come back in direction of the gyro and it is applicated right on the pivot, and the chariot translate slightly back and forth in the same direction as the gyro. This is due to the centrifugal force acting in full on the dead weight but as this dead mass is very low in comparison with the total weight of the gyro, the movements are short.

3- when the gyro slows more down, its center of mass seems to go back in direction of the center of the gyro. At this moment, the back and forth movement are more and more strong, and the whole system begin to be in accordance with the Eric Laithwaite debunker’s theory.

So both Eric Laithwaite and his debunkers are right, because it depends of the speed of the spinning of each particuliar gyro.
With of course a big advantage to Prof Laithwaite because he have discover the “mass transfer” possibility.

I claim nothing here, i have made this video on a linear path, because we can very well isolate the view and because air table orair track or floating boat are all submit to potential vertical movement and error. As the interesting part is when the gyro is at high speed and the chariot does not move at all, in think that the well known “slip stick “effect of the ball bearing is not fooling the result.

Voila hope this helps
