The dream windmill is a toy designed for children in poor mountain areas, which can rely on the wind to generate electricity and light. 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 post, children can remove the fully charged lamp pole and use it to supply light at night for writing. Thus, it can bring happiness and light to children in poor mountain areas.
