Hugh Pickens writes "A solar tree recently passed a key test and went on display on a busy street — the Ringstrasse — in Vienna, Austria providing light during the night-time even when the sun had been covered by clouds for four days in a row. The branches of the solar tree were decorated with 10 solar lamps, each one powered by 36 solar cells.and the tree included rechargeable batteries and electronic systems to measure the amount of light in the atmosphere and trigger the solar lamps to go on. "Not just trees but other objects could be decorated with solar cells and so keep streets well lit at night time," said Christina Werner from Cultural Project Management. Google uses a similar concept to light their parking lots with 3,000 solar panels that provide 10 percent of the Googleplex's power demand."
