One of the devices really has a pyramid shape (superimposing of rings).
This construction enables the spreading of a right torsion field created by the waves of shape.
The internal volume of the pyramid is filled with nano powders containing bulb shape particles.
These bulb shape particles contribute to amplify the static right torsion field so as to increase then the deviation of the incidental torsion fields.
Once these waves are deviated, one or two meters are approximately necessary to notice their disappearance.
