Steam Engines

Steam engines represent one of humanity's most transformative technological achievements, converting thermal energy from heated water into mechanical energy through the power of pressurized steam.

Basic Principles

The fundamental operation relies on basic thermodynamics:

1. Water is heated to create pressurized steam
2. The steam expands, pushing against a piston or turbine
3. This motion is converted into mechanical work
4. The steam condenses and the cycle repeats

Historical Development
