Rubber band energy storage.
This is just a simple device that stores energy on some rubber bands to generate electricity.
In the case of b 2 p 6 the ionic diffusion is strongly anisotropic a feature that can be potentially useful in affordable energy storage solutions such as metal ion batteries.
This would give a rubber band energy density of 2 2 megajoules m 3 for stretching and 8 9 megajoules m 3 for twisting.
The energy the rubber band has stored is related to the distance the rubber band will fly after being released.
When the rubber band is released the potential energy is quickly converted to kinetic energy.
You will investigate the relationship between the potential energy and kinetic energy in this system by seeing how far the rubber band flies when it is stretched to different lengths.
So can you guess one way to test how much energy a stretched rubber band contains.
Amazon s choice for storage for rubber bands.
That might seem like a lot of energy but remember that 3 3 gasoline has 34.
