Designer Jasper Hou has come up with a clockwork LED-based lighting design. To activate the lights, you rotate the clockwork part of the light. As the dial unwinds, the energy released is used to power the internal LED lights.
The lights are designed to replace candles, and therefore only emit an equivalent amount of light energy. Since candles are made from processing petroleum products and release carbon dioxide when burnt, the clockwork lights are a much more eco-friendly alternative. Oh, and the clockwork lights present no fire hazard either!
If this design goes into production, I imagine it would be a pretty popular product!
