Introductio n and Summary Dear readers: I trimmed this essay down to reflect that the essay delves far deeper into many issues that this essay originally covered.
My original energy essay was written aroundand could be considered the embryonic version of the version. If early humans did not learn to exploit new sources of energy, humankind would still be living with its ape cousins in the tropical forests.
Without the continual exploitation of new energy sources, there would have been no civilization, no Industrial Revolution and no looming global catastrophe.
Symbiogenesis, or endosymbiotic theory, is an evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms, first articulated in and by the Russian botanist Konstantin Mereschkowski, and advanced and substantiated with microbiological evidence by Lynn Margulis in It holds that the organelles . The Energy Racket. By Wade Frazier. Revised in June Introduction and Summary. A Brief Prehistory of Energy and Life on Earth. Early Civilization, Energy and the . Misc thoughts, memories, proto-essays, musings, etc. And on that dread day, the Ineffable One will summon the artificers and makers of graven images, and He will command them to give life to their creations, and failing, they and their creations will be dedicated to the flames.
Early protohumans migrated from Africa about two million years ago, probably following migrating African predators. Aboutyea rs ago, anatomically modern humans appeared.
By about 10, years ago, humanity had exterminated all the easily hunted large animalsand the hunter-gatherer lifestyle was no longer sustainable on a global basis. Domestication of animals and food crops led to civilization. Domesticating animals, plants and enslaving humans were the significant activities of early civilizationand ideological indoctrination began in those early days, as the slaves needed to be conditioned to accept their status.
The positions of the new elite classes also needed an acceptable justification. Early agricultural practices also exhausted the landsalthough the dynamic of deforestation, farming, and desertification persists to this day.
In the late 19th century, oil became the next fuel to undergo large-scale exploitation, and its use coincided with amassing capitalistic, monopolistic empires, significantly by United States robber barons, John Rockefeller most notably.
The process of extracting and using fossil fuels is environmentally disastrous. Rapid global warmingmainly caused by burning fossil fuels, is one of the greatest threats that humanity faces today.
Every significant industry and profession is largely a self-serving racket, and the larger and more powerful the industry or profession is, the more it resembles an outright racket, which I discovered the hard way during my adventures.
I participated in a significant effort to bring alternative energy to the marketplace, maybe the most significant ever. What happened to the ventures that Dennis Lee headed is a case study of how alternative energy is suppressed. Alternative energy has been systematically suppressed, on a global scale, for the past century, and free energy technology has probably existed for a long time.
The exploitation of energy may exterminate the human species, but it does not have to be that way.
If we wake up and begin caring, solving our problems is easy. If we stay asleep, we are doomed. The problem has a lot more to do with integrity than technology or intelligence. It is up to us.
As our star settled into its life, something happened on a tiny fragment that orbits it. Scientists have developed theories, partly based upon observations, which guess what may have happened a long time ago.
The oxygen-hydrogen compound that blankets Earth, known as water, would be a gas instead of a liquid, except for the peculiar way that water molecules are attracted to each otherdue to their electrical polarity.Fideisms Judaism is the Semitic monotheistic fideist religion based on the Old Testament's ( BCE) rules for the worship of Yahweh by his chosen people, the children of Abraham's son Isaac (c BCE)..
Zoroastrianism is the Persian monotheistic fideist religion founded by Zarathustra (cc BCE) and which teaches that good must be chosen over evil in order to achieve salvation. (used relatively in restrictive clauses having that as the antecedent): Damaged goods constituted part of that which was sold at the auction.
(used after a preposition to represent a specified antecedent): the horse on which I rode. (used relatively to represent a specified or implied antecedent) the one that; a particular one that: You may choose . AET Internal Combustion Engine Theory and Servicing.
This is a theory/laboratory course designed to introduce the student to basic heat engine types, their . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις.
The earliest instances of what might today be called genetic algorithms appeared in the late s and early s, programmed on computers by evolutionary biologists who were explicitly seeking to model aspects of natural evolution.
