I have a windup radio that works in a similar manner.
I won't be able to monitor a challenge at this time so the game is open to any iPF member who wishes to post the next challenge.
The guy who invented the wind up radio, Trevor Bayliss, had a great struggle to get financial backing for his invention.
UK retailers, the banks etc could not see a future for his invention. The radio was eventually brought into production and it's initial market was in Africa where folk in remote areas without electricity benefited from his invention.
His story should be made into a film. Perhaps that has happened.
Excuse me if my post contains errors, but I have written from memory, without resorting to Google, etc
