In the 21st century, innovations in sustainabletransportation will gain importance…
A new type of mobility must take over the leadingrole in road transportation this century.
Immediate Needs
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 freighttransportation in all industrial sectors.
•The number of commercial vehicles is expected to increase byabout 55 % in the next 20 years.
•A new type of mobility must take over the leading role in roadtransportation this century.
•The time interval of transformation is still unclear and dependson a lot of economically and ecologically influenced factors.

Carnot’s Hardware Modeled Hardware for Engine
Carnot’s Theoretical Model for Steam Engine
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 !!!!
