Wound spring makes electricity....

I recently heard about a technology that uses a spring to generate electricity.
You wind a handle or crank to tighten the spring. As the spring unwinds it provides power for radios etc.
Does anyone know what this technology is called? How to find some of the manufacturers and/oe products?

it's called stored energy. the energy used to wind a spring is then stored in the spring if it is not released. this stored energy can then turn a motor to make electricity. just think of an old clock that needs winding. the stored energy in the spring turns the gears.
