Abstract
The invention includes liquid weighted, variable inertia flywheels of various designs together with subsystems to selectively control the addition of liquid into and the removal of liquid from the flywheels while the flywheels rotate. In one embodiment liquid is removed and energy extracted through centrally mounted turbines. In other embodiments, liquid is extracted through various rotatable Pitot tube devices. In yet another embodiment liquid is added and removed through bucket wheels supported for rotation on a centrally located, independently rotatable carrier. Pairs of flywheels are further incorporated into continuously variable transmissions, together with fluid control devices to vary the fluid levels in and thus the moment of inertia of each of the flywheels for energy storage and extraction.
