This guy invented a device which uses a simple plastic belt to vibrate from wind blowing and generate a significant amount of electricity for its size. It is 10 times cheaper than regular electricity, more easy to build than a standard wind mill and much, much smaller. The belt vibrates and moves a magnet placed between two coils. As taught in elementary school, it generates electric current. With the device shown in the video he can power a radio, a LED and a wall clock. Interesting idea, don’t you think? That’s why he got the 2007 Breakthrough Award from Popular Mechanics.
