Reinventing the Wheel is A Good Thing
That clockwork MP3 player reminds me.
I have this idea about sustainable technology that it is often a matter of finding new applications for what are often actually old (non-combustion) sources of energy: solar heating, concentrated solar (like magnifying glass), windmills and watermills, hand cranks. And of course the bicycle and things of that ilk are back in favour too.
There are some great recent examples on ecogeek of mechanical power, eg a combined pedal/electric cycle car, a Sony camera prototype (pictured - & here's the link) which is hand powered by rolling its wheel on a table.
Would be interesting to speculate as to others that might be reinvented/rediscovered. I wondered if walking might be an interesting source (energy generated by compression in soles to charge batteries), also whether typing could part charge a laptop, treadmills could create lighting energy in gyms (when they arent in use you dont need much light?) and so on.
I'm probably reinventing the wheel here too, I cant be the first to have noticed all this.
