In Episode 2 of our second season of #toptechvoices, Irish inventor Fionn Ferreira joins our host, Georgia Lewis Anderson to discuss Innovations for a Greener Planet!

Listed on the Forbes 30 Under 30, Fionn created a magnet based method for extracting microplastics from water, positioning himself as a leading inventor in environmental science and winning the Global Grand Prize at the Google Science Fair in 2019 at just 18 years old!

Fionn also hosts "What's Next", a television series that focuses on young inventors, helping to inspire and guide the next generation of inventors.
