Build a working wind turbine to harness power out of thin air. Wind is one of the most promising sources of clean, renewable energy available today. Wind energy has been used for centuries to pump water and crush grain in windmills, and is now increasingly used to generate electricity to power our modern world. Assemble a wind turbine complete with electric generator, adjustable rotors, and wind speed indicator. Conduct more than 20 experiments with your wind turbine, including experiments with different numbers of rotor blades, different blade anglers and profiles, different wind speeds, different gear ratios, and so on. Use the wind turbine to generate mechanicval power to lift a heavy weight or generate electricity to light up an LED and charge a rechargeable battery. Learn the physics of wind turbines. Discover how wind occurs and why it is such a promising energy source. The full-color, 32 page experimental manual offers illustrated instructions and scientific information. Ages 8 and up. |
