## Overview

The Wind Power V4.0 STEM Experiment Kit lets you build a realistic 3-foot wind turbine with aerodynamic blades to generate electricity. Designed for outdoor use with a weatherproof battery box and ground stakes, it powers a small model car and charges batteries. Perfect for ages 8+, it includes a detailed manual to explore renewable energy concepts, making it an award-winning educational tool for hands-on STEM learning.

## Description

Our fourth generation wind turbine kit! Build a realistic 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 increasingly being used to generate electricity to power our modern world. Assemble a wind turbine complete with electric generator and adjustable rotor blades. The blades are designed with complex aerodynamic curves to look and work like modern-day wind turbine blades. Conduct experiments with your wind turbine, including experiments to optimize its performance by adjusting the angle of the blades and the placement of the turbine. Use the wind turbine to light up an LED and charge a rechargeable battery. Convert the generator into an electric motor and assemble a small electric car to demonstrate a tangible application for stored solar electricity. 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 history of this technology, and how wind energy can be used to power homes and electric cars. The full-color, 32-page manual offers illustrated instructions and scientific information.

Review: Fun and easy for adults and kids! - I am 20 years older than 18. I always enjoy tinkering. I am interested in wind generated power so I got this given I felt it was reasonably affordable. Very easy and forgiving to setup. The piece that houses the battery and motor compartments plug and plays between the trmie one and the car you can construct. Additionally, you will need rechargeable batteries for they are not included. Enjoy!

## Questions & Answers

**Q: My 4 year old is obsessed with wind turbines. Can this just run by itself indoors? Just for him to sit and watch?**
A: Thank you for your question. Wind Power 4 comes with an output mode. This means you can put a charged rechargeable battery (or an alkaline battery) in the turbine and switch it to output mode, which will spin the axle (which the blades connect to). Alternatively, you can charge the rechargeable battery by placing the turbine outside on input mode on a windy day. Then that energy can be used to turn the axle on output mode.

**Q: What types of batteries does it charge?**
A: Thank you for your question. Wind Power 4 charges a rechargeable AA battery.

**Q: Is the connector usb ?**
A: The wind turbine generator can charge rechargeable batteries, or run off of batteries. There are no USB connections.

**Q: Can you make it spin on its own without wind?**
A: Yes, you can spin the blades manually by hand or with a powerful fan. You can also set it to spin using battery power.
