Electronics and electrical engineering firm Siemens and lighting company Osram partnered to create an art installation for the seventeenth Conference of the Parties (COP 17), last year, to symbolise their commitment to a sustainable future.
Siemens commissioned South African artist Daniel Popper to design and build a 15-m-high baobab tree sculpture. The installation was made from reclaimed wood.
Osram provided 3 000 of its high-efficiency, light-emitting diode (LED) lights to light up the tree. The LEDs were powered by solar panels.
Stationary bicycles positioned around the tree were another means by which the tree could be lit. By pedaling on one of the 17 stationary bicycles, people could help provide the energy to power the tree and the faster one pedalled, the brighter the baobab tree shone.
Siemens states that the baobab tree was an appropriate symbol for the COP 17 climate talks, as it has, over the centuries, been a place where people meet and solve problems.
