2. Definition of the Course Title
According to basic Thermodynamics,
A system undergoes a cycle or process to create useful actions.
Thermodynamic representation of actions: Heat Transfer & Work Transfer.
Present course is focused only on an action called,
Power Generation : Rate of Positive Work Transfer
Conservation of Energy demands a need for resource.

3. The Principle of Design
What is the better method of operation for a Power generation system?
Process or Cycle ?!?!?!?
Before answering this question, we need to answer another basic question.
Why humans need this action?
How important is this reaction for sustainable human development?

4. Thermodynamic Classification of Living Species
Life on Earth
Carbon Energy Reservoirs
Autotrophs
Heterotrophs
Somatic Heterotrophs
Extra-Somatic Heterotrophs

5. Humans : Extra-somatic Heterotrophs
The humans are extrasomatic heterotrophs.
The ability to use energy extrasomatically enables human beings to use far more energy than any other heterotroph that has ever evolved.
The human population modified more and more of its environment by using extrasomatic energy to suit human needs.
The world's present population of over 5.5 billion is sustained and continues to grow through the use of extrasomatic energy.
The human race expanded its resource base so that for long periods it has exceeded contemporary requirements.

7. Cyclic Nature of Earth’s Eco System
Matter cycles in regions of energy flow; such cycles, visible in natural complex structures, including those of life, occur as limited material resources scramble to provide a vehicle for entropy export. {Schneider & Sagan, 2005}
