Kyriacou's work explores the intersection of cutting-edge hydrogen technology, nature's ingenious designs, and the uninhibited imagination of childhood. This speculative design practice employs a critical lens to challenge preconceived notions about the limitations of existing technologies and manufacturing processes, specifically focusing on the world of hydrogen. Through rigorous computational simulations and data-driven analysis informed by biomimicry and playful exploration, Kyriacou crafts intricate theoretical prototypes that exist solely within the realm of possibility, unburdened by constraints of the real. These speculative designs are not intended as blueprint for building a better future, but function as provocations, questioning the dominant narratives surrounding technological progress and offering alternative realities for the role of hydrogen energy in the world. Kyriacou blends technical precision with sensory descriptions and subtle satire, inviting audiences to reconsider their assumptions and engage in a playful re-imagining of futures. This critical approach highlights how our current perspectives might limit our future, encouraging a deeper reflection on the choices we make, and the futures they build.
