Brief History

• Created and patented by Robert Stirling (1790-1878)

• Invented stirling engine in 1816 which could not explode and produce more power.

• First patented Sterling Engine called “Economizer”

What is a Stirling Engine

• Device that converts heat energy to mechanical power by alternately compressing and expanding a fixed quantity of working fluid at different temperatures.

Environmental

• Flexible with all sources of energy• Solar energy • Hydro energy

Pros

• Heating source is external • The pressure in a sterling engine is very consistent • There is no required air source

Cons

• Heating source is external • Gas is contained with in the engine• Current methods for cooling

Types of Stirling Engines

1.Alpha Stirling Engine- contains two power pistons in separate cylinders, one "hot" piston and one "cold" piston. 2.Beta Stirling Engine- single power piston arranged within the same cylinder on the same shaft as a displacer piston. 3.Gamma Stirling Engine- power piston is mounted in a separate cylinder alongside the displacer piston cylinder.1. 2. 3.

Alpha Stirling Engine

Contains two power pistons in separate cylinders, one "hot" piston and one "cold" piston.

Beta Stirling Engine

Single power piston arranged within the same cylinder on the same shaft as a displacer piston.

Gamma Stirling Engine

Power piston is mounted in a separate cylinder alongside the displacer piston cylinder, but is still connected to the same flywheel.
