Different swing / swing

Different swing

In Africa, where power resources are scarce, children can play on the swing during the day, thus triggering and rotating the power generation device in the swing, converting kinetic energy into electric energy and providing lighting function at night. This not only eliminates the tedium of manual power generation, but also allows children to participate in the construction of the village and make a contribution to the village.
