This massive Sun Ray could sustainably power 220 homes in Melbourne

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. To capture the sun’s energy, Antonio Maccà tapped into linear Fresnel reflector technology, in which mirrors are used to focus sunlight onto a solar receiver. A power block tucked underground transforms the solar energy into electricity before feeding it into the city power grid. “Sun Ray is a new symbol of renewable energy, lighting the way to the State of Victoria’s zero- greenhouse gas (GHG) emissions target,” explained Antonio Maccà in his project statement. “It is also a cultural attractor for Melbourne, an investigation of light as a physical and symbolic source of illumination for life. It is a place for reflection, relaxation, learning and play — and it is a linear Fresnel reflector solar power plant that provides heat and electricity for hundreds of homes in St Kilda.” Related: This gigantic solar hourglass could power 1,000 Danish homes Residents and visitors can interact with the Sun Ray by using it as a shade canopy. The 50 primary mirror lines cast shade over the public park space, while the mirrors create a constantly changing play of light and shadow as they turn to track the sun. The winning design of the 2018 Land Art Generator Initiative Melbourne will be announced on October 11. + Land Art Generator Initiative Renderings by Antonio Maccà
