While we’ve covered innovations aimed at reducing shark deaths, whether it’s having sharks tweet their presence or by designing kit that repels attacks, most beach-related deaths in fact involve hard-to-detect fast moving currents called riptides. An Australian startup has found a way to reduce the risks. The Clever GIRL (Global Intelligent Rip Locator) is a floating buoy designed to alert beachgoers to the presence of riptides. The buoy converts the power of the fast moving currents into kinetic energy — the water itself drives a turbine that, once there’s a fast enough flow of water to be considered a rip,…
