The Aluna Project wants to site a 21st century Stonehenge right in the heart of London, as a beacon for sustainability to enlighten our time-poor, throw-away world. By building the world's first tidal powered Moon clockon the River Thames, artist Laura Williams wants to create an inspiring and informing public space where we can relearn about the science that has shaped our island nation. Aluna reminds London home of time that the natural rhythms of our watery world are being ignored at our peril.This 40metre diameter landmark will be truly sustainable - built from recycled glass and lit by the power of the Thames tides. Aluna will bethe first arts project of its kind in the world - once up and running, it will generate its own revenue by producing enough of the Moon's renewableenergy to keep the lights on for around 200 London homes. It could become a signature project for the Mayor and Deputy Mayor's climate change Action Plan and their drive to spearhead a decentralised energy revolution."Aluna" the Kogi of Colombia¹s word for light/spirit/meaning will chartthe Moons wax and wane, its rise and set, and the tides ebb and flow, bringing together art and science in an accessible ever-changing light sculpture. Initial discussions have been held with landowners Lee Valley Regional Park Authority and London Borough of Tower Hamlets regarding East India Dock Basin as an exciting potential location for the project. Here it will be a legacy for London 2012 and bring significant positive impact to the regeneration of East London and the Thames Gateway. Greenwich Council have recently endorsed the project and are now competing with Tower Hamlets to bring the project to their side of the river.The Moon has been important to religions and cultures around the worldsince the dawn of time and many of London¹s festivals are timed by the Moon. Aluna will mean something to all ages, faiths and cultures and is much more than a monumental timepiece it will be a public sculpture, visitor attraction, centre for learning and spiritual escape all within sight of the Meridian.With strong support from local authorities and potential sites on bothsides of the river, Aluna's team are working together with project champions and strategic advisors to raise £250k development funding by the end of July in order to realise this multicultural symbol for London in time for London 2012.
