Once upon a time a Turtle and a Rabbit had an argument about who was faster.They decided to settle the argument with a race. They agreed on a route and started off the race. The rabbit shot ahead and ran briskly for some time. Then seeing that he was far ahead of the turtle, he thought he’d sit under a tree for some time and relax before continuing the race. He sat under the tree and soon fell asleep. The turtle plodding on overtook him and soon finished the race, emerging as the undisputed champ. The rabbit woke up and realized that he’d lost the race.”The moral of the story is that slow and steady wins the race….is that end of story??..Nooo…

Once upon a time a psychology professor walked around on a stage while teaching stress management principles to an auditorium filled with students. As she raised a glass of water, everyone expected they’d be asked the typical “glass half empty or glass half full” question. Instead, with a smile on her face, the professor asked, “How heavy is this glass of water I’m holding?”
A thermodynamic system may be defined as any specified portion of matter in the universe which is under study. A system may consist of one or more substances. Or if we defined it in terms of physics then In physics, the term “system” usually refers to any set of physical interactions isolated from the rest of the universe. Anything outside of the system, including all factors and forces irrelevant to a discussion of that system, is known as the environment.e.g., portion of test tube where reaction is taking place, is called system.
Thermodynamics is the oldest branch of engineering science and specifically of physics. It deals with the relationships between heat and other forms of energy. In another terms we can say that it deals with the transfer of energy from one form to another form and one place to another place.Thermodynamic focuses on concepts surrounding energy, and in the various states that systems possess, as defined by their state variables such as pressure, temperature, volume, entropy, concentration and so on.
While the world is making the evolution towards cleaner and greener sources of transportation, we still have some years to go before making a full transition to these technologies. Even then it would take most of the world some further years to catch up to those innovations. Here we present a small device that could radically change the efficiency of conventional engines until that time comes.
