A laser ray is used to trace the vapour emmisions of the Salmisaari power plant in Helninki, transforming it into a giant environmental sculpture.
The emission cloud is tracked using a thermal camera that can see the hot air even on a foggy day. A powerful laser then traces a dynamic green cloud shape on top of the real cloud, while adjusting the size according to the current levels of electricity consumption by local residents.
The installation was on display in February, 2008, and was subsequently awarded the Ars Electronica Golden Nica in the ‘Hybrid Art’ category.
Check out a video of the installation:
