For now, this beautiful sculpture only exists in the imaginations of its designers, but with luck (and some serious investment money) it will soon be a reality. Aluna, the world's first tidal-powered lunar clock, was conceived by artist Laura Williams seven years ago while she was watching a solar eclipse.
Her vision is of a clock made up of three huge concentric and translucent glass rings that light up to show (1) the waxing and waning of the moon, (2) the moon's current phase, and (3) the ebb and flow of the tide. The clock would be entirely powered by tidal waters.
At around 40 meters wide and five storeys high, it's being dubbed a modern-day Stonehenge — a union of art, science, and spirituality. According to the design team, “Aluna makes the link between ourselves, the Earth, and the Moon. Water makes up 70% of our bodies, the oceans make up 70% of our planet, and the Moon pulls the water on and off the land.”
At present, politicians and scientists in London are spearheading a bid to build the first Aluna on the banks of the River Thames near Greenwich. A mirror-image structure may be constructed in the southern hemisphere, Australia. But there's a great deal of interest from cities all over the world, so Aluna could appear anywhere.
