I talked quite a lot last time about technology and the at present very popular viewpoint that technology is something that has been introduced to our life on our planet here by human beings. That man is inherently mischievous, and that he has really made quite a lot of trouble for himself. I do not subscribe to this at all. Everything that you will experience with me as we explore, consists of the discovering one principle after another that man has gradually, after enough experiences, been able to discover as operative in Universe, whether it is mass interattractiveness, or the principle of leverage, or whatever it might be. That these principles, then, what the word "ology," "technology," the "ology" is the knowledge acquired by humans, of the regarding then the techniques by which Universe has accomplished various extraordinary behaviors. So that the biology, we are learning how the bio, the zoological and the botanical do develop. What are the structural laws that are operative and so forth. So that all of the technology, the technique of the structuring, and the associating and disassociating, and the way in which energy is transformed, continually transforming. What are the methods of the transformations. And, I'd just like to get down to a very simple statement, that I really I hope you'll feel strongly about it, and find yourself in a position to counter when people talk about man as introducing technology, and this is something bad, that the Universe as far as I'm concerned, the Universe is technology. And what man has been given is the capability of his mind over and above the brain to discover the technology, and to the power of design that he was given that capability. And therefore I assume that it was part of the design that he was supposed to use that capability.
And, that we are really discovering then, is that what has happened, is that man in his fear, and in his drive of hunger and his looking out for his own family, his own side, has then developed technology early, very much as weapons, though he did a great deal of technology in learning how to pound the meals into grain and so forth, and how he could convert various discoveries of nature into eatability. But I find that as I go thru the anthropological museums, I'm sorry to say that really the biggest acceleration in technology seems to be in the way of the weapons. And the weapons possibly first they are tools or instruments of killing of animals; but they are spearing animals, though, and then they are spearing human beings. And, the biggest acceleration in our technology has been through the ages, then, in the development of weapons for warfare on the basis of the "you" or "me-ness" of the assumed inadequacy of life support on board of our planet due to man's being born ignorant and really not knowing enough about what is really going on.
But, what has transpired and with great acceleration during my lifetime, has been the discovery of uses of principles first for war, and then when the wars are over finding that an enormous production technology has been developed. As for instance, you have the water wheel going around the waterfall was there all the time, and now you have the water running the water wheel and is operating an electric generator. And the energy is continually going then, available over wire to do work at great distances. After the war is over, something very different came in with World War I, in relation to wars then had ever, apparently entered in earlier. Though we have Biblically the phrase "turning swords into plowshares." And that will be the simplest kind of phrase of converting the war developed technology to the support of life that comes in afterwards.
World War I, is then an enormous metallurgical war where human beings up to the time of World War I, being primarily supported by agriculture and fishing; and we find the metals coming in making possible then to tin a steel can so we could have food preserved and not be contaminated. Suddenly this metals world entered into the picture, and due to the alloys and the metallic resources being situated around our planet very differently from where the agrarian matters occurred where things could grow. Very often the mines were just where things couldn't grow on a great mountain side rocky mountain side. And so we find that World War I, is a world war because of the world's metallic resources being brought into play over and above the agricultural resources, which were, every time the wars came, up to World War I, you took the farm boys off the farms to do the fighting. You used up the farm foods, you trampled down the farms with your warring. And when the wars were over everybody was at very great disadvantage.
So, it came as an enormous surprise after World War I, and I always say that was world war and it's world war because it's no longer just a local, agricultural one. It's world war because you are using resources that come from around the complete earth, which are metallic resources, and the technical information that came out of all history and all countries. And so, suddenly then a warring over life support for total earth, and no longer just between two adjacent countries. And, with World War I, we have this occurs in a sequence of events of human beings learning about the technology of Universe and beginning to employ it. It is the first really great application of energies other than human muscle to the doing of work, because by this time we did have the electric generator, and it could be tied up to Niagara Falls and to other running waters.
And at the time of World War I, humanity took out of the ground, and put to work extraordinary numbers of metals, and in particular, copper and iron. Copper, as you know is a very preferred conductor. It's non-sparking and conducts electrical current almost the most efficient. Silver is just a little bit better, and gold a little better than silver as a conductor, but there is not enough silver or gold to be used functionally as conductors or as parts of electric motors. And copper, while it is not a plentiful material, is plentiful enough to be functionally used, so that copper became then the hand-maiden of the generation of electricity with the copper windings around the iron magnets. And we have then, copper became the conductor then to carry this power to great distances, and then be used again in the windings of the motors where you used the power that had been brought by the conducting wires.
In the one year, 1917, when the United States came into World War I, W.W.I as you remember began, as you remember, 1914, but three years later, the United States came into that war, and it was really drawn in by both the ally sides in Europe the Germans and the English, tried very hard to get America in on their side because of the enormous potential productivity that was there. And during that one year, 1917, humanity, and particularly in America, mined more copper and refined it and put it to work, in one year than man had produced copper in the whole history of man before, cumulatively all the copper that had ever been produced up to that time of World War I. That amount was way outdone by the copper produced in one year, 1917. Due then to copper being the essence of suddenly using energies other than the muscles of man to do extraordinary work.
When the war was over, and unlike the farm wars where I said the foods had been used up, things had been exhausted fields had been exhausted, men had been exhausted; suddenly with World War I over, the copper did not disintegrate, it did not go back into the mines. It stayed right where it was, and the water fall kept on going and so, we suddenly found that power was still being generated, and it was still being conducted to many places to produce work.
So, this was really the beginning of the technology, and the technology of employing energy onto levers other than the energy of human muscles or the muscles of horses, and animals. And it was an extraordinary productivity that suddenly was there. As a consequence, many changes began to occur. As, for instance, we had, as we ended World War I, the number of human beings that were at any economic success whatsoever, with any real hope of being able to carry on without doing some personal work themselves, was way less than 1% of humanity. And I developed some data to give me some insight in the changes that occurred post World War I in relation to humanity in general.
When we measure energy, the ability to do work with energy, the prime criteria of science through all the ages has been the ability to lift a given weight against gravity and a given height in a given amount of time; so you call it one foot pound per minute, or it could be one centimeter gram second. There are many different ways of expressing it. And, as we get into the electrical world, we get down to jewels and then we get down to kilowatts per hour, so that they are all inter-translatable in the terms of the centimeter gram seconds, lifting weight against gravity. So there have been a number, since science then started measuring energy in such a manner, there have been a number of experimental investigations done of work that can be done by human beings in a given amount of time. And it has been found the investigations have been done primarily by armies of great countries, the German army, the Swiss army, the English army, the American army have measured the amount of work a healthy young 20-year older can do with a given pack of a given weight and his own bodily weight. How much can he really climb in a day's work before he is exhausted going up a mountain grade, and you were able then to figure the foot pounds per minute. That was accomplished at an angle, like that, able then to discover what the average amount of work that can be done by a human being in a given day, out of the amount of energy he is consuming get a metabolic rating, metabolics being the conversions of energies into work. And we have internal metabolics that you and I, let's think about our digestion of foods and so forth, and we have external metabolics we do with machinery, by introducing energy to do work through levers. And the amount of work, then, we found that the human beings could do, an average, healthy young man, was then able to be stated in terms of man powers per day, or man powers per year. Cumulatively how many days he carries this on.
So that I was able to come to the calculation of man powers per year by taking and integrating the results of the experiments made by various armies around the world. There seemed to be a great consensus on the part of scientist about what this amount of work was. So, I had a man power per year figure. I wanted to use that in trying to assess the amount of work that could be done after W.W.I in contradistinction to the amount of work that could be done before W.W.I, by human beings using their minds and discovering principles, versus just using their muscles.
We find the, now that there is relative efficiency used in, engineering using the word efficiency. And efficiency, then identifies the amount of work you're getting out of a machine as ratio to the amount of energy you put into the machine. And again you use the same methods of rating of what the work potential is in the number of b.t.u.'s oh heat, you can rate these things in different ways, but the efficiency then, of a reciprocating engine for instance, is about only 15%, average of reciprocating engine around 15%.
