Every year, the James Dyson awards promote and encourage innovation in design, recognizing young designers and inventors for their problem-solving ideas. We speak with this year's Canada award winner and two runners up about their ingenious inventions. From a mechanical assistive device for people with limited hand mobility to an AI-powered system that identifies and prevents soil erosion in agriculture to a non-toxic fire retardant that keeps people safe without long-term health impacts, we learn what it takes to come up with innovative technologies that solve big problems.
