2. Happy New Year 2013 !!! http://web.iitd.ac.in/~pmvs

3. MEL 709 : HEAT EXCHANGERS P M V Subbarao Professor Mechanical Engineering Department I I T Delhi A Device which enhanced the value of fire/fuel !!! A True Mediator !!!

4. Earth and Energy Life on Earth is driven by energy. Autotrophs take it from solar radiation and create Energy Reservoirs on Earth.

5. Creators and Exploiters of Energy Reservoirs Heterotrophs take it from autotrophs. Energy captured slowly by photosynthesis is stored up, and as denser reservoirs of energy have come into being over the course of Earth's history

6. A way of Reducing Rate of Entropy Generation on Earth…… Energy Cycles on Earth w/o Humans

7. Human Evolution & Energy 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.

9. The Greatest Extra-somatic Action 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. Invention of FIRE, FLAME and TORCH

11. The First Civilized Extrasomatic Action!!!!! Fire Can only Heat Solids !!!!!

12. A Search for Ubuntu Device …. A generous, hospitable, friendly, caring and compassionate. They share what they have/get/earn…….. A person with ubuntu is open and available to others……. Various religions identified them as Mediators. Business Mediators. Energy Mediators – A first step in Civilization and Development…

13. EARLIEST TYPES OF HX : COOKING Primitive humans may first have savoured roast meat by chance, when the flesh of a beast killed in a forest fire was found to be more palatable and easier to chew and digest than the customary raw meat. They probably did not deliberately cook food, though, until long after they had learned to use fire for light and warmth. It has been speculated that Peking man roasted meats, but no clear evidence supports the theory. During Palaeolithic Period, Aurignacian people of southern France apparantly began to steam their food over hot embers by wrapping it in wet leaves. Crude procedures –as toasting wild grains on flat rocks and using shells, skulls, –or hollowed stones to heat liquids. Introduction of pottery during the Neolithic Period. A paste, toasted to crustiness when dropped on a hot stone, made the first bread.
