The basic principles of four representative unconventionalgyros are developed. The force between theplates of a charged capacitor manifests itself as-thebasis for rotor support in the electrostatic gyro. Thecryogenic gyro support is dependent on the unusual electricand magnetic behavior of metals at extremely lowtemperatures. The laser gyro utilizes high frequencyelectromagnetic radiation instead of angular momentumto sense inertial rotations. The angular momentum ofthe nuclear gyro is that of sub-atomic particles ofmatter.
