What if renewable energy infrastructure could be both functional and beautiful? Exploring that notion is Italian architectural practice Antonio Maccà, who designed ‘Sun Ray,’ a massive solar collector that could generate enough energy to power 220 Melbourne homes — with approximately 1,100 MWh of electricity produced annually. Shortlisted for this year’s Land Art Generator Initiative Melbourne design competition, the conceptual design was conceived as a symbol for the future of sustainable energy that also doubles as public artwork. Envisioned for the City of Port Phillip in Melbourne, Sun Ray consists of a series of flat mirrors — each with a single-axis tracking system — laid out in a round shape with a diameter of 279 feet and elevated atop slender steel columns.
