The floating geodesic dome Rising Moon was designed for the autumn festival “lantern wonderland” 2013 in Victoria Park in Hong Kong by the local architecture firm named Daydreamers. The dome has a 20 meter diameter, and for the surface covering 4800 five gallon (22,7 liter) polycarbonate water containers were used. These containers were mounted into a network of electric sockets with LED lighting. The sphere’s surface was triangulated – each triangle carried about 28 water containers. The main structure is a steel rod frame. The bottles were chosen for their resemblance with traditional Chinese beacon-shaped lanterns. In the interior of the dome 2300 regular PET bottles are suspended from the ceiling providing the effect of the sea. Since the pavilion is floating, the whole appears to be a complete sphere because of the reflection of the water. By manipulating the LED lights, multiple phases of the moon can be simulated on the surface – hence the name of the pavilion. Additionally in the top of the pavilion there is an opening in the roof which allows the real moonlight pass through the pavilion. According to Daydreamers architects, the whole building can be de-assembled and the parts (bottles) recycled.
The Japanese architect Tadao Ando designed a spectacular wall incorporating 17 400 PET bottles of 0,5 liter for the interior of the Morimoto restaurant in New York City. The bottles are filled with mineral water. The bottles are mounted horizontally on a frame by means of couplers. There are also LED lights at the couplers so that in this way the wall becomes a lighting element in the restaurant. The electricity is led horizontally on a bracing. The wall is two floors high.
