  12. I seem to remember one of my engineering instructors telling us that
  13. turbine engines in cars would not be feasible since the output shaft
  14. speed for efficient operation was so large compared to the speed needed
  15. for input to a typical automobile transmission.
  16.  
  17. It seems that very large gear ratios would be needed to bring the "efficient"
  18. turbine engine output shaft speed down to a range that a car can use.
  19. Therefore, a large reduction gear train would be needed.
  20.  
  21. Am I wrong here?
