Toyota has launched a new project to teach high school students how to build fuel cell cars. Well, OK, the company is teaching them how to build small, remote-controlled fuel cell cars, but it’s hoping that’s enough to ignite their interest in the technology. The automaker’s Hydrogen Horizon Automotive Challenge isn’t a full-blown, multi-year program like the drone and robotics course offered at one Japanese high school. But it will teach teens about climate change and the importance of alternative energy for a whole semester.
