Solar powered LED street lighting on the streets of Vienna by Welsh designer Ross Lovegrove.
The solar cells on the tree are able to store enough electricity in spite of receiving no direct solar light for days at a time because of the clouds.
Christina Werner from Cultural Project Management, Vienna reports that they show that solar trees really are a practical form of street lighting.
We hope that not only Vienna but the city of Christchurch will see the merits of using renewable energy for street lighting.
