  Hello,
  
  I will admit this isn’t my field.
  
  I would say rocket engines would offer benefits in terms of being lightweight and capable of producing immense amounts of power from fairly sustainable sources. But in terms of being used over normal car engines I think the noise may restrict that.
  
  Are you considering a career as a rocket scientist?
