  1. Siemens Education Topic 1: The Inspired Bus Company

  2. The Inspired Bus Company • Overall learning objectives: • To explore the challenges facing bus designers when designing the power system for a bus for an urban environment. • To investigate how different solutions can be identified and evaluated. • To collaborate to present recommendation for an effective solution. • Overall learning outcomes: • To have investigated and summarised key features of alternatives. • To have presented a well deserved case for a solution.

  3. The Inspired Bus Company • ‘Leon’s London’

  4. The Inspired Bus Company • Leon’s London • Why are there different kinds of passengers at different times of the day? • What impact does traffic congestion have on the bus journey? • Why is traffic pollution an important factor in the design of the bus? • What would be the problem in this context with using a bus that simply had a diesel engine driving the wheels?

  5. The Inspired Bus Company • Battery Power

  6. The Inspired Bus Company • Battery power • How would the batteries be charged up in a full sized vehicle? • Identify where energy is being transferred from and to. • Describe the environmental impact of this power system. • What might affect the operating range of this vehicle? • Summarise the advantages and disadvantages of this source.

  7. The Inspired Bus Company Fuel cell

  8. The Inspired Bus Company • Fuel cell • How would this work in a full sized vehicle? • Identify where energy is being transferred from and to. • Describe the environmental impact of this power system. • What might affect the operating range of the vehicle? • Summarise the advantages and disadvantages of this source.

  9. The Inspired Bus Company Diesel engine

  10. The Inspired Bus Company • Diesel engine • Identify where energy is being transferred from and to. • Describe the environmental impact of this power system. • What might affect the operating range of the vehicle? • Summarise the advantages and disadvantages of this source.

  11. The Inspired Bus Company • Racing car

  12. The Inspired Bus Company • Bicycle brakes

  13. The Inspired Bus Company • Bicycle brakes • What happens to the temperature of the brakes if the bike wheel is set in motion and the brakes applied? • What happens to the temperature of the brakes if the speed is increased? • What happens to the temperature of the brakes if the speed is held for longer before braking? • Where does the energy go when the wheel has stopped? • How repeatable are these results?

  14. The Inspired Bus Company • Using kinetic energy

  15. The Inspired Bus Company • London bus

  16. The Inspired Bus Company • Hybrid energy systems

  17. The Inspired Bus Company • Suggest an effective power source and explain why

  18. The Inspired Bus Company • Suggest an effective power source and explain why

  19. The Inspired Bus Company • Siemens ELFA drive system video

  20. The Inspired Bus Company • Group discussion

  21. The Inspired Bus Company • Route one: rail/bus station shuttle service

  22. The Inspired Bus Company • Route two: ‘inner circle’ service

  23. The Inspired Bus Company • Route three: city-airport link
