In the 21st century, innovations in sustainable
transportation will gain importance A new type
of mobility must take over the leading role in
road transportation this century.

Future transportation systems

• The price of petroleum products ? Time.
• The number of passenger cars ? Time.
• The trends indicate the largest growth rate to be
  in freight transportation in all industrial
  sectors.
• The number of commercial vehicles is expected to
  increase by about 55 in the next 20 years.
• A new type of mobility must take over the leading
  role in road transportation this century.
• The time interval of transformation is still
  unclear and depends on a lot of economically and
  ecologically influenced factors.

Carnots Quick Conclusion to Mundane Problem
Higher the temperature of heat addition, higher
will be the efficiency. Lower the temperature of
heat rejection, higher will be the
efficiency. Efficiency of a Reversible Engine is
independent of work fluid !!!!
