Pulley

For example, if the mechanical advantage of a pulley system is 3, the pulley system has 3 fixed pulleys acting on an object, therefore reducing the force that needs to be applied by a factor of 3. Due to the rules of conservation of energy however, the distance that this force needs to act over is three times the distance that the load will actually move.

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…

Why don''t we use weights to store energy?

Just the weights we use are made not from lead, but from water. Many water reservoirs are also used to store energy by pumping water up when you have energy surplus, and letting it come down through the generators when you need energy. All you need for this purpose is two or more reservoirs at different altitudes. Share.
