Today, as you are traveling you may see wind turbines providing eco-friendly electrical power to farms or even industrial areas. You can have a smaller version that will at least provide you with an indicator of the wind. The Mathmos Wind Lights is eight inches tall and lights up when the wind blows. A small puff of air causes the rotor blades to spin which cause the LED lights to glow. You can choose from red or blue LED lights. If you plan to use the lights in the garden, be sure that the wind lights can get a bit of wind or it will not do any good.
