French-Israeli start-up Solar Tree Europ has unveiled its first "eTree" in Nevers, northern France. Based on the acacia tree, which thrives in arid conditions, the device has large leaf-like organic solar panels that convert sunlight into electricity, allowing passers-by to charge their phones or surf the web, while also providing shade, water and street lighting. Similar trees have been put up in 37,000 cities in Israel and the US.
