![]() ![]() ![]() Because the moon-advancing mechanism works off of the tides’ changes and not their absolute heights, it can accommodate all ranges of tidal amplitude. Each time its direction of travel changes (from flood to ebb or ebb to flood) the mast activates a mechanical linkage (represented by the orange elements on the model) that rotates the moon. The pipe serves to guide the float, to dampen the effect of short-period waves, and to protect the float from flotsam and jetsam.Īttached to, and buoyed by, the float is a mast (shown on the model and in the drawing with a yellow flag flying from its top) running up through the deck to the sculpture’s roof, its height reflecting the height of the river below. Inside is a float, which rises and falls with the changing water level in the river. Each change in tide-from flood to ebb and from ebb to flood- rotates the artificial moon slightly so that the face it presents changes in synchrony with the face of the real moon.Ī large-diameter pipe with an opening at the bottom extends from deck level down into the water several feet below the lowest anticipated tide. In a way, it acts as a kind of mirror: for instead of the moon powering the tides, here it is the tides that power the moon. The Luna Phaser is about the tides in the river and their relationship to their principal cause, the moon. ![]()
