This is just a simple device that stores energy on some rubber bands to generate electricity.
Rubber band energy storage.
When the rubber band is released the potential energy is quickly converted to kinetic energy.
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.

That might seem like a lot of energy but remember that 3 3 gasoline has 34.

So can you guess one way to test how much energy a stretched rubber band contains.
This would give a rubber band energy density of 2 2 megajoules m 3 for stretching and 8 9 megajoules m 3 for twisting.
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.
