How does a wind-up generator work?

[Don A. Gilmore]

Hi guys:

How does a wind-up generator (like in a wind-up radio) work? Is it
simply a dynamo that charges a NiCd battery, or is energy stored in a
power spring (or neither)?

Thanks for any replies.

....Just to clarify. I realize that a power spring can't produce
electrical power. I just wondered if the mechanism truly winds up
(like a wind-up toy) and then this mechanical energy is converted into
electrical energy somehow.
