Unification of Transport Phenomena based on General Relativity

The vision to conduct the unification of transport phenonema based on general relativity is given. No matter what kind of transport phenomena, there is an upper limit for the transport. It is light speed. As to a heat engine working between two heat reservoirs with two different temperatures, there is an upper limit of the thermal efficiency. The heat-work structure in thermodynamics is analogical to the space-time structure in general relativity. For the three modes of transport including conduction, convection, and radiation, they may be able to be described by one mathematical framework in which the light-based axiom (light speed is a constant) plays a crucial role.
