Two 18-year-old students from Pennsylvania have developed an innovative, low-cost exhaust filter that turns harmful vehicle emissions into oxygen using microalgae. Rohan Kapoor and Jack Reichert created the Go Green Filter, a compact device that easily attaches to a car’s tailpipe. The filter uses living microalgae to capture carbon dioxide and other pollutants, releasing clean oxygen in their place. Inspired by research from an MIT professor, the pair spent nearly a year perfecting their prototype. According to Chester County Press, the device costs only about $50 to produce and has demonstrated a remarkable 74% reduction in emissions during testing. The teenagers estimate that if their filter were installed on all vehicles worldwide, it could potentially cut global carbon emissions by more than 16%. A simple yet powerful idea that proves young innovators can make a real impact on the climate crisis.
