Rotary energy storage mechanism
Spinning the motor causes air to be forced through a tube, one-way valve, and storage tank. Opening the valve allows the compressed air in the tank (potential energy) to flow back through the tube and motor, spinning it in reverse. As the number of rotations increases, the pressure increases, acting to stop the axle for a given torque.

How to Find Energy Stored in a Spring: A Comprehensive Guide
Once we have the spring constant k and the extension x, we can use the formula for elastic potential energy to calculate the energy stored in the spring: EPE = 0.5 × k × x^2. For example, if we have a spring with a spring constant of 80 N/m that is extended by 1.5 m, the energy stored in the spring would be: EPE = 0.5 × 80 N/m × (1.5 …
ENERGY STORAGE
SPRINGS. When w inding up a coiled watch spring (spiral torsion spring) the energy is stored and slowly released, providing power to the watch mechanism. This is basically the same mechanism that provides power to wind-up radios, timers and some torches. Spring steel is often used to manufacture the spiral torsion spring.
