Here's a fun idea. A flashlight that doesn't need batteries. Instead, the user simply blows into one end, and light comes out the other. In between is a mini turbine, which,when spun by blowing, charges two magnets creating an electrical charge thus lighting the bulb. Voila!I'm sure cyclists all over the world would love to get one of these for Christmas.
beat me with a moldy stick, but this appears to be smart idea even nowadays. I smell the green buck!
