Re: Gravity powered LED. What a neat idea!
Gravity is simpler (no spring, no ratchet winder), cheaper and more reliable. And you can adjust the weight to adjust the brightness and duration of the light.
As a retired engineer I have to say the idea is simply brilliant!
It could be scaled up to generate more power. I'd like one to power lights and TV.
