With crystal experts Swarovski, Marjan van Aubel created Cyanometer, a work that uses crystals to make solar cells more efficient. By cutting the glass at certain angles, the light is refracted in a way that focuses more intensely on the solar cell, increasing its efficiency.
The portable solar crystal harvests light during daylight hours and, placed into a docking station, it can power a light installation that gives the sensation of ‘taking the sky indoors’. The stones used for the ring-shaped device are opals, which scatter the light in the same way the sky does. The more light the solar crystals receive in the daytime, the more intense light the installation can bring indoors. Cyanometer takes its name from an invention from 1789 that was used to measure the colour of the sky.
