When she was 14 years old, Hannah Herbst won the Young Scientist Challenge by building an ocean-powered turbine. The inspiration for this project came after she received a letter from a pen pal in Ethiopia, who described how she had no access to lights or fresh water to drink. Hannah decided to use her engineering skills to help mitigate the global energy crisis. After months of research, Hannah created a computer model and then a 3D-printed prototype, which she tested in the Boca Raton waterway. Powered by oceanic tides, her turbine produced enough energy to power three car batteries. Hannah believes that a turbine like this could be implemented in the developing world to desalinate water and run centrifuges to help with blood tests. Hannah became interested in science after spending a summer at an engineering camp and she hopes other young scientists like her will find similar inspiration.
