The dream windmill is a toy designed for children in poor mountain areas, which can rely on the wind to generate electricity and illuminate. Children play with it during the day, and rotating blades can drive micro-generators to generate electricity. By converting wind energy into electricity and storing it in the battery of the lamp pole, children can remove the fully charged lamp pole at night and use it to illuminate for writing. It can bring happiness and light to children in poor mountain areas.
