After learning that Tesla also had profound knowledge in mechanics, Hu Weidong brought Li Siguang with him when he visited him. However, he did not expect that the two had a very happy conversation as soon as they met, and instead left Hu Weidong aside. It turned out that Special
In the past ten years, because no one was willing to fund his scientific research that seemed to have no commercial value, Silla, the first person in the history of applied science, had to conduct theoretical research that he didn't like very much.
But Tesla was Tesla. Even if he changed his profession to engage in theory, it would still be shocking. Based on Newtonian classical mechanics, he actually picked up the ether hypothesis that had been overturned by Einstein and initially completed a set of
Its own theoretical system can not only justify itself, but also, like the theory of relativity, can explain those phenomena that the original Newtonian mechanics cannot explain (the official translation of the relevant work is "Dynamic Theory of Gravity", but it is obviously a mistranslation, "gravity" should
It should be changed to "gravity". The two are the same word in English, but the meanings of the words in Chinese are still different.). But even Tesla himself knew that his theory would definitely not be accepted by the mainstream scientific community.
Accepted (Historically, this work has been sealed by the U.S. government to this day. Unless the theory of relativity is completely overturned, it is estimated that it will never be officially published.), because if there are two sets of completely different theories at the same time, it will inevitably lead to thinking
Chaos will have a serious impact on both production, life and scientific research. Among the two theories, the theory of relativity takes advantage of preconceptions and is more consistent with so-called common sense, so the mainstream scientific community will naturally choose it.
It's not Tesla's theory. Not to mention Tesla's popularity is so poor...
The situation of Li Siguang's geomechanics is very similar to this. No one can prove that it is a wrong theory, and it is indeed easy to use in practice. However, the geological community will never accept that "geological phenomena can be calculated using mechanical methods."
This concept, had it not been later supported by the new Chinese government in history, Li Siguang’s geomechanics fate would not have been much different from Tesla’s theory. Both of them are genius scientists who have never been born in the world, and now they are
We are in the same boat, and naturally we see each other right away...
Although it was very unpleasant to be left aside, just watching was enough to make Hu Weidong realize the extraordinaryness of Tesla. However, no matter how high the theoretical level is, it does not mean much to China, which is now poor, weak and backward.
They would only focus on solving practical problems. So he quickly and rudely interrupted the two genius scientists' unobtrusive conversation, "Mr. Tesla, the reason why alternating current is superior to direct current is because the voltage of alternating current can be easily increased, thus greatly increasing the voltage of alternating current."
Reduce the loss of long-distance power transmission. However, with the development of the world economy, the demand for power in remote areas will definitely increase. The transmission distance will naturally continue to lengthen, so the transmission voltage will continue to increase. In addition, as the wires
With the improvement of materials, the resistance loss will become smaller and smaller. Therefore, the loss caused by inductive reactance will exceed the resistance sooner or later, and DC has always been superior to AC in terms of safety, so can I say that, as long as the transformer is solved?
Question, will direct current replace alternating current again?"
"The backward method of power transmission relying on wires will eventually be replaced by wireless power transmission. Wireless power transmission can only transmit alternating current!" Tesla immediately shook his head and retorted.
Before Hu Weidong visited Tesla, he specially collected some information and knew that the wireless power transmission technology envisioned by Tesla (Note 1) actually uses the resonance effect of the earth's ionosphere. In theory, it is not impossible to realize, but this technology
Even if ultra-long-distance low-loss wireless power transmission can be achieved, it will not have any commercial value. Because if this technology is really practical, it means that any receiving device on the earth can share the power sent by the output device.
The receiving device is very cheap. Due to the selfish nature of human beings, most of the electricity sent will be stolen for free. The power supplier will inevitably go bankrupt, and if it is very expensive, then this invention cannot be promoted at all. Maybe only humans, uh, should be
After all human beings have entered the independent society (even if controllable nuclear fusion is successful, power generation and transmission will still require capital investment.) After that, will this technology really come in handy?…
After hearing this conclusion from Hu Weidong, Tesla still shook his head stubbornly and replied, "In the future, humans will definitely be able to utilize all forms of energy, and then the problem you mentioned will not be a problem."
When Hu Weidong heard this sentence at first, he thought Tesla was talking about a perpetual motion machine that had failed countless times in history but was still succeeded by others. He couldn't help frowning, but at this time Tesla explained, "Energy is nowhere to be found.
It is not there, but it will never be exhausted. We cannot turn one calorie of energy into ten calories, but as long as we can transform energy between various types at a very small cost, for humans, it is equivalent to having
It has unlimited energy, just like what you say in ancient Chinese proverb, 'Heaven and man are one'..."
"Why do these scientific geniuses dive into philosophy at an early age? Einstein did the same, and so did Newton..." Hu Weidong couldn't help frowning, and simply gave him a slap in the face, "This
It's philosophy. It's an ideal situation. How can it be so simple in reality? What's more, to put it bluntly, besides you, who else in the world will study this kind of problem? And you are 80 years old, how many years can you live? Do you have time to solve it?
Are there any results of practical significance? Do you also know that it is too late? Then after you die, there will be no successors to these researches. In the future, you will only be the second Leonardo da Vinci. You may be able to be amazed by future generations, but to say it is correct
How much contribution has mankind made? At least the rest of your life... is all in vain!"
Tesla didn't say anything after hearing this, but just grabbed his hair hard...
Now that he has said that, Hu Weidong simply stated the reason for his visit, "Most Chinese people can't even fill their stomachs now. The money we have now is all they saved from their teeth. If it's better,
It’s easy to invite you back to China, but you spend all day studying these useless things, so how are we supposed to explain it to the hundreds of millions of poor people in China who are still suffering from hunger and cold?”
Note 1: The Tesla coil that is so popular now is just Tesla's initial failure and cannot eliminate distance energy attenuation. Therefore, he later proposed to use the earth's ionosphere, a natural electromagnetic resonance cavity, to achieve it.
The idea of long-distance wireless power transmission. (To be continued. If you like this work, you are welcome to come to (.) to vote for recommendations and monthly votes. Your support is my biggest motivation.)
