Abstract
A flywheel energy storage device containing at least one rotary element (1) which is capable of floating and rotating on liquid and/or in liquid, at least one element which is capable of transferring energy onto the rotary element (1) and at least one generator (3) which is capable of transferring the energy from the rotary element (1) wherein the rotary element (1) is axleless. A method of use of the flywheel energy storage device in such manner that the energy is accumulated as kinetic energy of at least one rotary element (1) that floats and rotates on liquid or in liquid.
Claims14
A flywheel energy storage device containing at least one rotary element which is capable of floating and rotating on liquid or in liquid, at least one element which is capable of transferring energy onto the rotary element and at least one generator which is capable of transferring the energy from the rotary element, wherein:
- (i) the rotary element is axleless;
- (ii) the rotary element is at least partially hollow and at least partially fillable with liquid;
- and
- (iii) the rotary element is provided with at least one opening arranged on the rotary element in such manner that when the rotary element is on or in liquid, at least a lower edge of the opening is below the level of liquid, while the opening is arranged on the rotary element in such manner that it is closer to the axis of rotation of the rotary element than an inside part of an outer wall of the rotary element, thereby allowing the rotary element to autonomously change its mass through filling and discharging of liquid according to the size of the centrifugal force caused by the rotary element.
