Impact of Fire on Extra-somatism

The Accounting : A major concern in Extrasomatism If we are living in a cave and realized our extrasomatism, we need to start accounting with some degree of precise standard. We might be having fire, stick and stone tools in our cave. There, starts a measurement system. Like when you grunt and say how many beast you killed for dinner, 1, 2 or measurements. When gathering wood for a fire you would ask for so much wood.....measurement. To live in our physical world we need to understand it (The Knowledge).

Innovation and Conservation

The Major Break Through Research due to extrasomatic Behaviour…. Development of Equipment for Enhancing the Utility of Fire/fuel. Development of Theory & Systems for Motive Power.

The Aelopile In 130BC. Hero, a Greek mathematician and scientist is credited with inventing the first practical application of steam power, the aelopile.

Branca's Steam Turbine In 1629, Giovanni Branca, of the Italian town of Loretto, described, in a work' published at Rome, a number of ingenious contrivances.

The Savery 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 Events in Savery Engine

Thomas Savery As an English army officer, Thomas Savery was once ejected from the Lord of the Admiralty's office as a lunatic because he proposed a ship that could be propelled by side- mounted wheels rather than by wind or oars. He exhibited great fondness for mechanics, and for mathematicians natural philosophy and gave much time to experimenting, to the contriving of various kinds of apparatus, and to invention.

Various Cycles of Nature Water Cycles Energy Cycles Life Cycles of Animals Life Cycles of Plants Seasonal Cycles Planetary Cycles Rock Cycles Geo-Physical Cycles Chemical Cycles Disease Cycles

Rock Cycle

Energy Interaction in Rock Cycle

A cyclic Event persists for long time (for ever)….. Cyclic devices are immortal…. The Engineering Philosophy of Savery

Newcomen Engine The original Thomas Newcomen engine was invented in 1712.

James Watt radically improved Newcomen's engine (1769) by condensing the steam outside the cylinder. James Watt’s Engine

James Watt Engine Watt's Double-Acting Engine, The Watt Hammer, Trevithick's Locomotive, 1804 The " Atlantlc," 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…..
