The combination of art, green energy and environment was the motivation for building a “solar tree”. The tree consists of a mechanical basis built of construction steel surrounded by the wood of a real tree. The branches of a real tree, fixed to the trunk are holding seven big artificial leaves. On top of them, we mounted solar cells, which are capable of delivering energy to a power outlet, installed in the trunk of the tree. On a sunny day, the guests of Roskilde Festival 2010, can expect around 150 W to charge their mobile phones, shave, cool beer, etc.
