Thermodynamic Classification of Living Species Life on Earth Carbon Energy Reservoirs Autotrophs Heterotrophs Somatic Heterotrophs Extra-Somatic Heterotrophs

Humans : Extra-somatic Heterotrophs The humans are extrasomatic heterotrophs. The ability to use energy extrasomatically enables human beings to use far more energy than any other heterotroph that has ever evolved. The human population modified more and more of its environment by using extrasomatic energy to suit human needs. The world's present population of over 5.5 billion is sustained and continues to grow through the use of extrasomatic energy. The human race expanded its resource base so that for long periods it has exceeded contemporary requirements.

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}

Origin of Energy Systems & Technologies

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.

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).

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

Origin of Steam : Basis of Scientific & Technological Research Denis Papin, while working at Huygens and of Boyle, started to be interested in the vapor. Several geniuses of science tried before him to try out an unspecified machine which would run on the vapor, but their efforts were useless. It is into 1707 that Denis Papin made his first great realization: the boat with vapor. This superb invention brought much controversy near the boatmen, who destroyed the ship.

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.
