Solar power from energy-harvesting trees – Watch the video!

Scientists at VTT 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 leaves form an electronic system complete with wiring that conduct
