Back in the mid 90s, British inventor Trevor Baylis  came up with his most famous invention, the wind-up radio (also known as clockwork radio). The idea was simple; to make do without batteries/mains connections.

You wind the device up and then it works for a certain amount of time. When it runs out, you can wind it up again.

Since then, a few other devices have been developped based on a similar design. Wind-up torches are now very popular, wind-up mobile chargers are starting to emerge, and Tevor Baylis’ company, Freeplay, has announced the wind-up media player.

I might be asking for too much technically but i’d like it if someone came up with a design for a wind-up kettle, a wind-up digital camera, and a wind-up alarm-clock.
