Creation of Hardware Working in A Cycle : Solution for All Extra-somatic Needs P M V Subbarao Professor Mechanical Engineering Department Continuous Generation of Most Useful Resource
Conceptual Research by Thomas Savery • Thomas Savery exhibited great fondness for mechanics, mathematics, natural philosophy. • He gave much time • to experimenting, • to the contriving of various kinds of apparatus, and • to invention.

Secret of Nature • Water Cycles • Energy Cycles • Life Cycles of Animals • Life Cycles of Plants • Seasonal Cycles • Planetary Cycles • Geo-Physical Cycles • Chemical Cycles • Disease Cycles • Rock Cycles
The Engineering Philosophy by Thomas Savery A cyclic process serves for long time (for ever)….. Cyclic devices are immortal….
The Savery Mine Pump/Engine Thomas Savery, July 2, 1698, patented the design of the first engine which had the most important advance in actual construction. A working model was submitted to the Royal Society of London.

Cyclic Process in Savery Engine Starting Point:
Newcomen Engine : First Step in Innovation thru Conservation The original Thomas Newcomen engine was invented in 1712.
Anatomy of Newcomen Engine 1736 Watt born1755 Watt trained in London1763 Watt discovers problem with Newcomen engine
James Watt’s Engine : Most Important Innovation for Conservation James Watt radically improved Newcomen's engine (1769) by condensing the steam outside the cylinder .
James Watt Engine • Watt's Double-Acting Engine, 1784. • The Watt Hammer, 1784. • Trevithick's Locomotive, 1804 • The " Atlantlc," 1832. • Steam Engine Reached its pinnacle in size when it was called to drive 5 MW electric generator. Steam Engine As an Alternate to Horse or Cattle…..
The Family of Steam Engines A Direct Hardware Creations to the Essential Need …..
Questions Raised by Nicholas Leonard Sadi Carnot • How was the work developed by the engine related to the heat supplied (amount of coal burned)? • Was there an upper limit to this work and what condition could lead to its release? • Was water the best material to use, or might not some other liquid such as alcohol provide a more effective medium? • Might not a gas such as air be more advantageous than a condensable vapour? The thermal efficiency of boiler has increased from about 30% in 1800 to over 90% in a modern boiler….
The Human Idols : Steam Power ~1760 : James Watt ~1820 : Sadi Carnot W Rankine ~ 1860
The History of Electric Power • Many accounts begin power’s story at the demonstration of electric conduction by Englishman Stephen Gray, which led to the 1740 invention of glass friction generators in Leyden, Germany. • This inspired the invention of the battery by Italy’s Alessandro Volta in 1800. • Humphry Davy’s first effective “arc lamp” in 1808. • 1820, Hans Christian Oersted’s demonstration of the relationship between electricity and magnetism.
The Human Idols : Electric Power Michael Faraday • In 1820, in arguably the most pivotal contribution to modern power systems. • Michael Faraday and Joseph Henry invented a primitive electric motor. • In 1831, documented that an electric current can be produced in a wire moving near a magnet—demonstrating the principle of the generator.
Pearl Street Station Thomas Edison in September 1882 achieved his vision of a full-scale central power station
The Birth of Power Plant • In 1882 the world's first coal-fired public power station, the Edison Electric Light Station, was built in London. • This was a project of Thomas Edison organized by Edward Johnson. • A Babcock & Wilcox boiler powered a 125-horsepower steam engine that drove a 27-ton generator. • This supplied electricity to premises in the area that could be reached through the culverts of the viaduct without digging up the road, which was the monopoly of the gas companies. • The customers included the City Temple and the Old Bailey. • Another important customer was the Telegraph Office of the General Post Office, but this could not be reached though the culverts. Johnson arranged for the supply cable to be run overhead, via Holborn Tavern and Newgate.
