Two Pennsylvania teenagers, Rohan Kapoor and Jack Reichert, have designed a low-cost exhaust filter that uses living microalgae to convert vehicle emissions into oxygen. Their invention, known as the Go Green filter, attaches directly to a car’s exhaust pipe. As exhaust gases pass through, the microalgae absorb carbon dioxide and release fresh oxygen, helping reduce the environmental impact of everyday driving.
Their idea was inspired by bioengineering concepts from MIT, and the teens spent nearly a year refining the prototype to prove the system could work outside a lab. The project demonstrates how biological solutions — especially algae-based carbon capture — can be applied to small-scale devices, not just industrial settings. Their design also highlights how accessible eco-innovation can be when creativity meets scientific curiosity.
While still experimental, the Go Green filter showcases the potential of nature-powered technology to complement electric vehicle adoption and reduce emissions from the millions of gasoline cars still on the road. Projects like this spark important conversations about how young innovators can contribute practical, affordable ideas to the fight against climate change.
