Sunlight to illuminate Olympic taekwondo venue(China Foto Press)Updated: 2007-05-30 14:08
On May 28, 2007, workers at the Gymnasium of Beijing University of Science and Technology were fixing ball-like light-gathering shades on the roof of the building. Each shade contains up to 150 light-pipes that temporarily store the outdoor light and then shed it evenly on the gymnasium through diffusing devices. The gym with daytime electricity-free lighting is the venue for the taekwondo competitions during the 2008 Olympic Games. |
