Colours under water: automated lighting illustrates energy production

Located in Gunma Prefecture, some 100km north of Tokyo, Geo-E-Site is an open-plan, subterranean environment located 300m beneath one of Japan’s most important hydro-electric facilities. The purpose is to illustrate all the steps that lead to the production of hydroelectric power, a precious and inexhaustible source of our Earth, by means of a guided itinerary.

Geo-E-Site hosts thousands of visitors from both Japan and overseas every year, and is especially popular with school trips. Six Clay Paky CP Color 150-E projectors have been used to bring life to the subterranean environment and, at the same time, to highlight some of the fundamental parts of the power station through the astute use of light.

“The use of projectors with IP65 protection became indispensable since the place, by its nature, is very damp and dusty” says Keiko Yonezawa, President of the Strise architectural practice, which implemented the project. “The Clay Paky CP Color units confirmed their complete reliability, which we had already experienced in numerous other applications throughout Japan”.

Elsewhere in the 20,000 sq m facility is a room containing displays illustrating the history of the power station, along with explanations of the operating principles of power production. Two Clay Paky VIP 300 units have been installed in this area to reproduce the effect of water through the use of rotating glass gobos.
