First, assemble a wind turbine complete with electric generator, adjustable rotors, and wind speed indicator. Then, conduct more than 20 experiments with your wind turbine, including experiments with different numbers of rotor blades, different blade angles and profiles, different wind speeds, different gear ratios, and so on. Use the wind turbine to generate mechanical power to lift a heavy weight or generate electricity to light up an LED and charge a rechargeable battery.
During the experiments, you will learn the physics of force and motion as it applies to wind power technology. Learn how to measure and calculate the different forces acting on the rotor blades by breaking them down into vectors.
Discover how the sun makes the wind, providing us with an endless source of energy. Read about different types of wind turbines and windmills.
The full-color, 32-page experiment manual offers illustrated instructions and scientific information.
• build a working wind turbine
• harness mechanical energy to lift weights
• generate electricity to light an LED and charge a battery
• learn the physics of wind turbines
• discover how wind occurs and why it is such a promising energy source.
For ages 8 and up.

My 2nd son directly assemble it the moment he receives it but he got one gear reversed so it didn't work at first. We then test the rotor, the battery holder, wires, etc but they all work well so I told him to disassemble and reassemble and see where it has gone wrong. After he figured out the reverse gear, it works nicely and to quote him "the led shines brighter compared to using battery". So this is a very good kit, with one minor flaw: the plastic material is too fragile, one can easily breaks it accidentally, which I did (fortunately not enough damage to make it stop working)

I bought this for my grandson who loves construction toys. I know he will love it and learn more about wind power. I had to laugh, at his birthday party, because his dad picked it up after of the present opening to see what fun they were going to have building!
