The Japanese tradition of growing artistically shaped trees created the miniature bonsai. French artist Vivien Muller takes the bonsai concept a step further, creating artistically shaped miniature trees with solar-panel leaves to charge your gadgets. The Electree is a charging station that juices up mobile devices via USB, powered completely by light.



It's up to the user to position the 27 leaves, or solar panels, in an orientation that optimizes efficiency. The panels rotate freely, allowing the user to create an unlimited number of shapes. Energy produced during the day is stored in a 13,500 milliampere-hour-capacity battery hidden in the base. Mullen explains how he borrowed the design from nature.
