[imbnyxus] Human-powered electronic lock

Create an electronic lock (perhaps door lock) which does not require batteries or be connected to electrical mains.  Instead, power is supplied each time by the person operating it: pull a lever or turn a crank to generate electricity.  Even better, step up onto a platform which descends due to your weight, generating electricity.  6 inch * 100 lb = 68 joules = 6.8 seconds * 10 watt which seems plenty for operating a lock.

Ideally we would like reliability and ease of repairs / cost of ownership comparable or better than a fully mechanical lock.
