Transcript

  • There was so much security they had to put covers over the cameras on our phones. (air whooshing) We're back from our road trip. I'm here with my production crew, these wonderful people. I've been saying that I care about renewable energy and the environment, and I want a sustainable future. But how do you show that you care about something? Step... Read More

Questions & Answers

Q: How does a hydrogen fuel cell car work?

Hydrogen fuel cells work by allowing hydrogen to come in contact with oxygen through a platinum catalyst, causing a chemical reaction that produces electricity. This electricity powers the car's motor.

Q: How is hydrogen stored in the car?

The hydrogen is stored in the car as a compressed gas. The tanks are made up of three layers, including a plastic liner, carbon fiber for strength, and glass fiber for containment.

Q: What safety measures are in place to prevent hydrogen leaks?

Strict regulations ensure minimal hydrogen leakage from the tanks. The tanks are designed with multiple layers and materials that prevent the hydrogen from escaping. The process of filling and using the tanks is highly regulated.

Q: Why is Toyota developing fuel cell electric vehicles instead of focusing on battery electric vehicles?

Toyota believes that a combination of both fuel cell electric vehicles and battery electric vehicles is necessary to achieve significant emission reductions. They argue that certain applications, such as long-distance travel and heavy vehicles, may be better suited for fuel cell technology.

Summary & Key Takeaways

  • Dianna teams up with Toyota to learn about renewable energy by driving the Mirai, a hydrogen fuel cell car, on a road trip.

  • The trip includes visits to experts and deep dives into different aspects of renewable energy.

  • The Mirai runs on hydrogen fuel cells, which produce electricity through a chemical reaction between hydrogen and oxygen, enabling the car to be refueled quickly.
