The Electree was once a concept by Vivien Muller a couple of years ago, and the device has now evolved into an actual unit – thanks to a small family-run company taking up the task of manufacturing it. Gotta love the wordplay on the name, as its leaves are actually photovoltaic panels which enable users to recharge mobile devices through sunlight. There is a total of 42 cells, where all energy harvested by the panels will be kept in an onboard battery. When fully charged, the battery is able to feed mobile devices through a USB port. There is a limited edition (can you say extremely?) of just 20 specimens, so if you have a penchant for the weird and quirky, why not give it a shot? It ought to shave off a couple of dollars from your monthly power bill at best.
