Every ocean lover knows the perils of getting caught inside of a rip current. Experienced swimmers know it is very easy to escape the narrow channel of quick water by floating and and can drag you further in the ocean or by swimming alongside the shore. However, novice beachgoers often panic, and strive to swim to land, placing themselves prone to drowning because of fatigue. Based on the US National Ocean Service, the currents kill about 100 Americans annually and take into account 80% of the lifeguard rescues. These scary statistics may soon become a subject put to rest, as a consequence of Clever GIRL (Global Intelligent Rip Locator), a good buoy that alerts swimmers from the presence of deadly rip currents.
The ingenious set up is the brainchild of Australian teenager Maddison King, who created Clever GIRL as being a problem for her Grade 12 Technology and design class. The 18-year-old, who functions as a lifeguard during her down time, developed the brilliant idea after discovering that most kids could not detect rip currents.
The basketball-sized plastic foam-filled buoy, that can be attached to a chain of similar devices as well as ocean floor, is outfitted having a small propeller – akin towards one available on many boats. As soon as the water begins to churn at speeds that could reach over 70 centimeters per second, it spins the propeller fast enough to power lights atop the buoy, warning swimmers to remain seated totally free of the region.
Though it appears obvious, their kids needed to overcome numerous design challenges in order that the float was effective, safe, and ecological. She picked a sore point since it is simple to grasp inside the bright sunlight and likewise because the color operates as a universal red light for tourists that do not speak a nearby language. The device’s smooth surface and handles ensure swimmers aren’t getting hurt, as the black, white, and red striped underside, keeps sharks as well as other animals at bay. To counteract the turbine’s metal ball bearing from rusting, Maddison selected an environmentally-friendly waterproof marine grade lubricant. She also hopes to include a siren to Clever GIRL’s next iteration.
Not surprisingly, the invention has earned Maddison numerous accolades, including a finalist position along at the BHP Billiton Science and Engineering Awards, among Australia’s most prestigious student science awards. She also won a “Young Scientist Award” which qualified her to showcase the invention alongside 1,800 other students from 75 countries in the 2017 Intel International Science and Engineering Fair.
Maddison, that is currently seeking funding to bring Clever GIRL to offer, knows that the current $300USD cost to help make the buoy is just too big steep to deploy the clever contraption across beaches worldwide. She, however, estimates that your cost is often reduced to some more affordable $100 USD the moment the system is manufactured in larger quantities. Are you aware that name? The witty teenager believes it is perfect considering the fact that “girls are cleverer than boys.”
