Rotors are tapped in

 This test outcome is consistent with research by Marc G. Millis, former NASA propulsion physicist and founder of the Breakthrough Propulsion Physics Program. Millis’ work explored how mechanical and electromagnetic interactions within a closed system could produce measurable net forces under dynamic conditions. The CID™ results support this principle — showing that no thrust occurs when the rotors are fixed, and that propulsion arises only when rotational motion across the stator gap is allowed

This video shows an early test of the Centrifugal Impulse Drive (CID™) using a single-ring configuration mounted on a torsion balance.
In this setup, the rotors were taped in place to prevent motion and isolate internal system dynamics.
As in later tests, the drive was remotely operated with no physical contact, verifying that no thrust is produced under constraint conditions.
This experiment helped confirm that CID™ thrust arises only when the rotors are free to move dynamically.

 This test shows a single-ring configuration of the Centrifugal Impulse Drive (CID™) producing upward-directed thrust.

This configuration isolates one active rotor assembly, highlighting the directional component of CID™ thrust and supporting ongoing efforts to quantify lift under controlled conditions. 

This early experiment tested a CID™ rotor with all magnetic elements removed, running at high speed to determine whether any gyroscopic precession or inertial coupling could account for the thrust seen in magnetic configurations.

The result: no measurable precession or external force was detected.
This confirmed that the magnetic interaction itself, not mechanical rotation, is responsible for CID™’s directional thrust in later tests.

Conventional gyroscopes show clear precession when torque is applied, as seen in standard physics demos.
In contrast, the CID™ rotor with no magnets showed no precession or motion, even at high speed — confirming that CID™ thrust is not gyroscopic but arises from its magnetic interaction when active.
