As a User: The Revolution of Energy Users and Producers
This essay traces a shift in how we understand energy, use, and agency—from centralized systems and consumer identities toward distributed, bodily, and generative forms of participation. Drawing on energy history, design theory, political philosophy, and Indigenous ethics, it argues that being a “user” is not a passive role but a political position. To use is to act, to produce, and to take responsibility across time. As a user, I produce energy.

What is the potential of a playground that remained intact during a typhoon? — “A Creative Plan for Responding to Climate Change”
On September 6, 2024, Typhoon Yagi swept through Haikou. While the storm caused disruptions across the city, our community-built Playground without Walls survived completely intact.
How did simple materials like rope, tape, and wire withstand a Category 17 typhoon? Beyond engineering, it was the collaboration, creativity, and resilience of our team and local children that made this possible.

Playgrounds as the Materialization of Care: The Technology, Ethics, and Social Functions of Children's Play Facilities
This article was initially framed around Playground Without Walls as a case study. It proposes a systemic structural hypothesis: if children’s physical activity and play can be reimagined as a form of public energy production—then could play itself become a basis for reconfiguring infrastructural logics, mechanisms of benefit-sharing, and even ethics of care?

Happy Power Energy Playground: The Binlian New Village Case Study
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. Built in 20 days on ¥80 000 crowdfunding, it logged 1 000 play sessions and energy for 300 phone charges in one weekend, sparked pop-up markets, and became the area’s sole emergency charger after storms. A replicable toolkit is forthcomi

“Play” Is a Right, and Also a Power | Children’s Day Special Feature: How PlayPower Generates Well-being for Children
In “Play Is a Right—and a Power,” I examine how playgrounds have evolved from 19th-century factories to today’s over-controlled “safety cages,” and share how PlayPower’s child-centered, modular “behavioral energy” approach turns overlooked spaces into dynamic learning ecosystems. By treating children’s actions, emotions, and imagination as tangible energy, we not only illuminate playgrounds—but also empower kids as real co-creators of their communities. Join me in rethinking
