Most smartphone users have probably experienced the frustration of a dead battery. Now Project Solaire have designed a backpack that incorporates a solar panel into the fabric to keep devices charged wherever you go. This is a pretty neat way of capturing solar energy in a way that is easy, accessible and highly useful. Embedded within a simple backpack the rugged designs are ideal for festival goers or hikers to use when they are far from a power point. In fact the brains behind the concept are big festival goers and were frustrated with their devices dying in the midst of a concert. “We figured there has to be a solution,” says the brand’s Deme MaRie.
