Nicolas Leonard Sadi Carnot (1796--1832): a pioneer of thermodynamics.
Sadi Carnot in the dress uniform of a student of the Ecole Polytechnique.
Carnot is noted for his discovery of the Carnot heat engine or Carnot cycle.
The Carnot heat engine has the most efficient cycle possible for an engine or refrigerator.
He also had a famous father, Lazare Carnot (1753--1823), one of the French Revolution leaders. Carnot was called the ``Organizer of Victory''.

Just a cute gym gif that illustrates a cycle.
Actually, a part of the cycle is off-screen.
Credit: Unknown to me, but I trust he/she is not aggrieved that I publicly display his wares.
Download site: None. The gym.gif was just sent me by someone and the details are long-forgotten.

Legend (by image creator: see below)
- Condenser coil (hot side heat exchanger)
- Expansion valve (gas expands, cools and liquifies)
- Evaporator coil (cold side heat exchanger)
- Compressor
- Red = Gas at high pressure and temperature
- Pink = Gas at high pressure and reduced temperature
- Blue = Liquid at low pressure and greatly reduced temperature
- Light Blue = Gas at low pressure and warmer temperature

A diagram of a electric generator and a turbine for hydropower.
Actual images of electric generators and turbines in power plants are often complex.
So many prongs and ridges and covers that it is hard to see what is happening.
This image, of course, cannot stand for the whole range of possibilities, but it is generally instructive.
