Playful Energy is a multidisciplinary design research project for artists, architects, landscape designers, and other creatives working with engineers and scientists to bring forward human-centered solutions for sustainable energy infrastructures that enhance the city as works of public art in a playful way. What if energy harvesting is not only for providing power but also for awaking our senses? Playful Energy contributes to review advanced technologies of harvesting energy and research potential design concepts and developments. We aim to encourage people’s sustainable behaviors through the experiences.
