4. Conservative Philosophy of Universe • Matter cycles in regions of energy flow; such cycles, visible in natural complex structures, including those of life, occur as limited material resources scramble to provide a vehicle for entropy export. {Schneider & Sagan, 2005}

7. The Greatest Extra-somatic Action Discovery of FIRE, FLAME and TORCH • Fire is a discovery rather than an invention. • Homo erectus probably discovered fire by accident. • Fire was most likely given to man as a 'gift from the heavens' when a bolt of lightning struck a tree or a bush, suddenly starting it on fire. • The flaming touch and the campfire probably constituted early man's first use of 'artificial' lighting. • As early as 400,000 BC, fire was kindled in the caves of Peking man. • Prehistoric man, used primitive lamps to illuminate his cave. • Various Oils were used as fuels.

9. 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 fruits you collected for dinner, 1, 2 or 3.....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).

15. 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. • http://inventors.about.com/library/inventors/blsavery1.htm

16. 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.

25. Newcomen Engine : First Step in Innovation for Conservation The original Thomas Newcomen engine was invented in 1712.

26. James Watt’s Engine : A major Innovation for Conservation James Watt radically improved Newcomen's engine (1769) by condensing the steam outside the cylinder .

27. 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…..

28. High Tech extra-somatic Invention for Food Security In the 1800s natural refrigeration was a vibrant part of the economy. Natural ice harvested from the pristine rivers and lakes of the northern United States, particularly those in New England, was in demand. Harvested ice was stored in large quantities in ice houses and covered with sawdust for insulation. Ice was delivered to as far away as India, where it was welcomed

29. Frederic Tudor’s ice ship, the Ice King Ice shipments were not always warmly received. About 1820, the New Orleans mayor shocked the crew of the first sailing vessel to deliver ice to the city. He ordered the ice to be thrown into the sea

30. Cyclic Energy Systems for Food Preservation • During the 1800s many mechanical type refrigeration systems were being invented. • Refrigerants such as sulphur dioxide, methyl chloride, ether, carbon dioxide, as well as wine, brandy, vinegar, etc., were used. • The early refrigeration systems designed between 1850 and 1920 produced ice year-round to compete with harvested ice. • As early as the 1880s, Carré ammonia absorption systems operated in south Texas. • In the early 1900s Some refrigeration systems used carbon dioxide (CO2) as the refrigerant.

33. Definition of Thermodynamics • Thermodynamics is defined as the science of energy. • The name Thermodynamics stems from the Greek words therme (Heat) and dynamics (Power). • Clearly depicting the early efforts to convert heat into power. Steam power already had many uses - draining water from mines, excavating ports and rivers, forging iron, grinding grain, and spinning and weaving cloth - but it was inefficient.

38. Steam Wagon/Tractor : Last decade of 19th Century

39. Steam Tractors • The first steam tractors that were designed specifically for agricultural uses were portable engines built on skids or on wheels and transported to the work area using horses. • Later models used the power of the steam engine itself to power a drive train to move the machine and were first known as "traction drive" engines. • This was which eventually was shortened to "tractor". • By 1921, steam tractors had demonstrated clear economic advantages over horse power for heavy hauling and short journeys.

43. Human Idols : Thermal Environment Controls : Willis Haviland Carrier • In 1902, heat and humidity was ruining a publication being printed in color in Brooklyn, N.Y. • At that time, the art and science of air conditioning was just beginning to evolve. • Solving this printing problem lead to the start of industrial process air conditioning. • Nurtured by a young engineer named Willis Haviland Carrier.
