One or more spinning flywheels are adapted to despin or partially despin a rotating mass such as a satellite and to convert the rotational energy into heat or electrical energy. The flywheels have one degree of freedom, parallel to the satellite, spin axis. This one degree of freedom allows the flywheel to precess in the manner of a gyroscope. As the flywheel precesses it turns a shaft which drives an electrical generator which produces electrical power that can be taken out of the despin device to drive external electrical devices that will disperse the rotational energy in the form of heat, light or electrically driven chemical changes. The flywheels exchange rotational energy after the spin vector of the spinning flywheel becomes congruent with the spin vector of the spinning satellite, thereby allowing the energy extraction process to be repeated. Bearing loss makeup energy is restored to the spinning flywheel system by feedback from the extracted satellite rotational energy.
