The idea of powering a bike headlight with the wind is a natural until you start thinking about what happens when the bicycle has stopped. Taiwanese designer Hsieh Jung-Ya has you covered, because this design concept of a mini-turbine mounted on bike handlebars stores that wind energy in a rechargeable lithium battery, keeping its 1700lux LED light shining bright even when the bike isn't moving.

But still, is this better than a wheel-generated light? Wouldn't this cause excessive drag? Combine the energy-storage idea with a drag-free design and then we'll talk.
