Happy Power’s off-grid playground in Haikou’s Binlian New Village turns kids’ motion into power. Co-designed by children, its modular seesaw-Ferris wheel, bike spin disk, 360° gyro and hamster wheel slip into tight alleys and resist typhoons.

In this context, the “HappyPower” project offers a sustainable solution that combines low-carbon interaction, green energy, and co-creative experiences—introducing interactive installations and environmental education into the heart of Laoshicun’s transformation.
