Steam Engines

Background

Generating Steam by heating water above its boiling point and using the resulting pressure was to the basis of the first engines to replace wind-, water-, and muscle-power. In the 1st Century AD, the Greek geometer and inventor Hero (Heron) of Alexandria built an engine that converted the velocity of a steam jet into rotational movement: The Hero Engine - the first steam driven engine. The basic idea of the Steam Engine was born. Thomas Newcomen's invention of the first practical steam engine in 1705 and its improvement by James Watt sixty years later mark the beginning of the Industrial Revolution and the basis for energy supply in modern society. It's a real mystery why it took the best part of two millennia before significant progress on Hero's approach was made. Today the optimized Clausius Rankine cycle is the most common thermodynamic steam process in the conventional power plants that supply the immense demand for electrical power for modern society. The basic concept of the Steam Engine, but using alternative working fluids instead of water, will probably play a significant role in future energy systems powered by solar and geothermal heat. The engines on this page are reminiscent of early steam technology and an exciting introduction to the thermodynamics of heat engines.

HeroEngine - Engine driven by Steam Repulsion

The idea of the HeroEngine, also known as an aeolipile, is considered to be the first recorded approach to constructing a steam driven engine. The device consists of an air-tight glass sphere with curved pipes projecting from it. Water inside the rotating chamber is heated by an external burner (not included). As the water boils, the steam escapes through the pipes creating a reaction force that causes the device to spin.

Steamer - Repulsion Steam Boat

What at first sight looks very toy-like, is in fact a very clever physical system: The main driving mechanism consists of a small boiler and two connected pipes. With a pipette put a small amount of water into the boiler, light the candle (pipette and 3 candles included) and put the boat on the surface of a bath of water, garden pond, etc. As the water boils, the steam escapes through the two pipes; the resulting reaction force pushes the boat along. When the boiler runs out of water, the condensation of steam in the pipes creates a negative pressure that sucks fresh water back into the boiler and starts the cycle again. A great example of the self-stabilization of oscillating systems.

Steamy - Candle Steam Engine

Steamy, one of the smallest steam engines in the world, uses a single food-warmer candle for fuel. It consists of a removable piston and flywheel unit, a boiler and a stand. Most parts are made of high quality brass. Simply fill the small boiler with a few milliliters of water and place the engine in its special stand. A few minutes after lighting the candle you can start the engine with a smooth kick of the flywheel and get about 6 minutes of operation with one water charge. A miniature version of the old steam technology: small, compact and a piece of art for your desk (height ~ 9cm)
