Solar power from energy-harvesting trees

Scientists at VTT Technical Research Centre of Finland Ltd have developed a prototype of a tree that harvests solar energy from its surroundings - whether indoors or outdoors - stores it and turns it into electricity to power small devices such as mobile phones, humidifiers, thermometers and LED light bulbs. The technology can also be used to harvest kinetic energy from the environment. The video is produced by VTT (htpp://) and created by ID BBN.
