How did it all start?

HERON OF ALEJANDRIA

Heron of Alexandria was born in the 1st century A.D. in Egypt. He was a Greek physicist and mathematician that lived in Alexandria in the first and second centuries A.D. As a mathematician, he made modest contributions to pure science.

BIOGRAPHY

OPERATION OF THE AEOLIPILE

Is a simple, bladeless radial steam turbine which spins when the central water container is heated. Torque is produced by steam jets exiting the turbine. The Greek-Egyptian mathematician and engineer Hero of Alexandria was the inventor of the machine.

INFORMATION

James Watt

James Wyatt was born on August 3, 1746 and died on September 4, 1813. He was a Scottish mechanical engineer, inventor and chemist, who was fashionable among the aristocrats of the time. The improvements he made to Newcomen's engine gave rise to what was known as the steam engine, which would prove fundamental in the development of the first Industrial Revolution..

Steam engine and 1st industrial revolution

1st Indutrial Revolution

Steam engine

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine.

The Industrial Revolution or First Industrial Revolution is the process of economic, social and technological transformation that began in the second half of the eighteenth century in the Kingdom of Great Britain, spread a few decades later to much of Western Europe and Anglo-Saxon America, and concluded between 1820 and 1840. This period witnessed the greatest set of economic, technological and social transformations in human history since the Neolithic period, which saw the transition from a rural economy based primarily on agriculture and trade to an urban, industrialized and mechanized economy.

General operation of the watt steam engine

Watt realised that the heat needed to warm the cylinder could be saved by adding a separate condensing cylinder. After the power cylinder was filled with steam, a valve was opened to the secondary cylinder, allowing the steam to flow into it and be condensed, which drew the steam from the main cylinder causing the power stroke. The condensing cylinder was water cooled to keep the steam condensing. At the end of the power stroke, the valve was closed so the power cylinder could be filled with steam as the piston moved to the top. The result was the same cycle as Newcomen's design, but without any cooling of the power cylinder which was immediately ready for another stroke.

pop pop engine

Year?

Who invented it?

In the year 1891.

It was created by a Frenchman named Thomas Piot. Filed a patent application in the UK for a pop pop boat using a small boiler and 2 pipes.

Where?

It was invented in UK.

operation of a pop pop boat

More information

A pop pop boat is powered by a very simple heat engine. This engine consists of a small boiler, which is connected to an exhaust tube. When heat is applied to the boiler, water in the boiler evaporates, producing steam. The expanding steam is suddenly pushed out of the boiler, making a "pop" sound, and pushes some of the water out of the exhaust tube, propelling the boat forward. The water then boils and the cycle repeats.
