What is the purpose of the fluid flywheel?

The purpose of a fluid flywheel is to store and transfer energy using a fluid medium, typically hydraulic fluid, to create rotational motion. It acts as a mechanical energy storage device that can absorb excess energy and release it when needed, helping to smooth out fluctuations in power demand and supply. This technology is often used in applications like hybrid vehicles and industrial machinery to enhance efficiency and dynamic response. Additionally, it can help reduce wear on mechanical components by minimizing direct mechanical coupling.
