Demos to Prepare:

King Hiero's Steam Ball.

Assorted  Boomerian engines:
Steam Power Plant.
Steamboat engine.
Steam Tractor.
Stirling Hot Air Engine.

Action and Reaction Steam Turbine Engine

A Heat Engine opened Greek Temple doors when a fire offering was built on an altar. Expanding hot air and steam pushed water into a counter weight to open the Temple doors showing that the God of the Temple was pleased with the offering.

Reciprocating Steam Engine

The sliding valve directs the steam such that it pushes the piston
both up and down every stroke.

The Bridge and Engine Order Telegraph to the great steam engines below.

The Great Triple Expansion Engines of a Steam Ship

Triple Expansion Animation

The steam passes through three sets of cylinders
for maximum efficiency.

Cranks and Eccentrics of the
Triple Expansion Engine

Crank Shaft

Pistons and Sliding Valves

Shaft Alley to the Propeller

The Reversing Engine

The Sliding Valves are reversed to
change the direction of the steam flow.

The Oil Burners

Roaring oil burners beneath the water filled tubes make
steam for the SS Jeremiah O’Brien.

Water Tube Boiler surrounded by the flames above.

The Condenser changes the exhause steam back
to liquid to be recycled. Sea water is used to
cool the steam.

Wendy inspects the Stanley Automobile steam engine of 1905.
Pulleys belts and gears transfer the power.
Steam Rules in Boomeria!

Boomeria Engine Room

The Stirling Cylcle Engine

This engine uses hot air and atmospheric pressure.

Internal Combustion Engine

Uses gasoline to produce expanding gases to push the pistons.
The Four Strokes: Intake, Compression, Ignition-Power, Exhaust.
