Inspired by Percy Shelley’s Prometheus Unbound, András Cséfalvay presents a three-act animated video opera exploring humanity’s pursuit of unlimited energy and the costs of progress. Through mythological figures—Prometheus, Asia, and Cosmia— the opera delves into nuclear energy debates, ecological dilemmas, and the balance between knowledge and domination. Set against a backdrop inspired by the Bátaapáti nuclear waste repository in Hungary, the characters debate utopian visions of transitioning from nuclear fission to fusion, examining humanity’s unsustainable demands. Prometheus promises boundless energy in exchange for freedom, raising questions about the path forward and its implications. The opera blends conceptual art with experimental music, using mytho-poetry and speculative storytelling to reflect on culture, technology, and climate challenges. Local children’s voices are woven into the soundscape, adding a collaborative, immersive element that deepens its exploration of humanity's impact on nature.
