Intel ISEF Team Profile – Maddison King – Clever GIRL (Global Intelligent Rip Locator)

With an average of 21 Australians drowning each year in ocean rips and 90 percent of beach rescues related to rips, many swimmers lives would be saved if they were alerted in advance to avoid dangerous beaches. Inspired by her work as a lifeguard, Maddison King developed a warning system for rips, powered by the rips themselves. A turbine in her device uses the energy from the rip to power a warning signal to swimmers. Her biggest challenge was making the device waterproof and establishing an anchoring system that would not interfere with the turbine.
