Energy saving initiatives: The Light Blossom

Now here´s a good idea from Philips. Create a street light that acts like a flower, using the sun´s rays to charge cells during the day, rotating like a daisy to face the sun, then in the evenings release the stored energy as light. Proximity sensors mean the light only comes on when there is movement nearby, in an attemt to reduce light pollution and still be safe. Saves laying cables too so they could be used in remote areas. I think it´s quite an attractive design too in a future-urban kind of way.
