I just came across something genuinely incredible happening out in the Saudi desert. In the Al Nafud region they have set up solar powered light beacons that point the way to nearby water sources. They charge during the day then shine bright at night so anyone who gets lost can follow the beam and reach safety. It is such a simple idea yet it has the potential to save lives in a place where getting disoriented can be deadly. Cool mix of old world desert travel and modern tech.
