Hydrocar introduces students to the hybrid technology that is fueling today’s automotive revolution!

Hydrocar demonstrates a complete, clean-energy system with solar to hydrogen power generation.

Powered by electricity from sunlight, the reversible fuel cell illustrates the principles of water electrolysis, separating hydrogen from water and then recombining these elements to create power in an extremely efficient process. What’s more, the car can steer independently to avoid running into obstacles.
