This is an interesting proposal
We are slightly wary of its seeming self-importance and feel of large corporate public art type stuff
Still – here is the info from the website
“Aluna is a unique proposal for the world’s first tidal powered Moon Clock. It will change the way we consider time and understand our planet.
Larger than Stonehenge, Aluna’s forty metre wide, five storey high structure is made up of three concentric translucent recycled glass rings.
By looking at how each ring is illuminated, you can follow the Moon’s movements, its current phase and the ebb and flow of the tides. This animation of light is called Alunatime.
Using the latest design and technologies, Alunatime will be powered directly by the tides using turbines.
A waterside landmark and a public sculpture, Aluna unites art, science and spirituality and is an ever-changing reminder of the natural cycles that have shaped our past”
