PolluCell: Using Waster Materials and Pollution to Generate Electricity
Sahil Doshi
2014 Winner
Meet Sahil. Sahil entered the competition because he loves science and he wanted to get to know others who shared similar interests. His battery cell invention will use carbon dioxide and other waste materials to help clear the atmosphere from greenhouse gas emissions and, additionally, be a low-cost alternative for electricity in developing countries.
Finsen Headphones: Treating Mid-Ear Infections Using Machine Learning and Phototherapy
Leanne Fan
2022 Winner
Every year, there are 700 million cases of mid-ear infections (Otitis Media) and nearly 21,000 deaths worldwide. Many of those impacted are children and underprivileged populations. Without medical access and or healthcare, diagnosis and treatment of mid-ear infections are often difficult. Leanne’s invention, Finsen Headphones, provides a low-cost option to detect and treat a mid-ear infection using machine learning and blue light therapy – potentially preventing up to 60% of hearing loss in children.
