Sunlight – Mirror

An exploration of the mirror as hardware, specifically as a tool for manipulating sunlight. Across history, reflected sunlight has been wielded as signal, weapon, and energy source—from the legend of Archimedes concentrating solar rays to burn enemy ships, to solar ovens and vast fields of robotic mirrors (heliostats) that concentrate sunlight into usable power. This project begins with a survey of mirrors as active hardware in astronomy and energy systems: telescopes that extend perception; concentrators that gather and direct energy; and reflective strategies for cooling and climate mitigation, from New York City’s Cool Roofs program to speculative geo-engineering initiatives. From these precedents, the project turns toward heliostat systems as tools for redistributing sunlight. For the past three years, I have researched and built a personal-use heliostat. Perched on the windowsill, with two motors programmed to follow the sun’s movement, and tilting accordingly, this automated heliostat splashed light like a fountain. It altered spatial and bodily rhythms, moods, and attention. While I continue to iterate on the personal heliostat, this proposal expands the question to infrastructure. What might cities become if rooftops behaved like fish scales—responsive, reflective, sensitive to one another? Mirrors as open hardware harness our most primal energy source.
