After learning that Tesla is also quite accomplished in mechanics, Hu Weidong brought Li Siguang with him when he visited him, but he didn't expect the two to talk happily as soon as they met, but left Hu Weidong aside. It turned out that in the past ten years, Tesla has had no one willing to fund him to conduct various scientific research that seems to have no commercial value, and the first person in the history of applied science has to conduct research that he does not like very much.

But Tesla is Tesla, even if it is shocking to change his career to engage in theory, he actually picked up the aether hypothesis that had been overturned by Einstein based on Newton's classical mechanics, and preliminarily completed a set of his own theoretical system, which can not only justify itself, but also explain those phenomena that the original Newtonian mechanics cannot explain like the theory of relativity (the official translation of the relevant work is called "The Dynamic Theory of Gravity", but it is obviously a mistranslation, and "gravity" should be changed to "gravity". In English, the two are the same word, but there are differences in the meaning of words in Chinese. ）。 But even Tesla himself knew that his theory would not be accepted by the mainstream scientific community (historically, this work has been sealed by the U.S. government to this day, and it is estimated that it will never be officially published unless the theory of relativity is completely overturned). Because if there are two completely different theories at the same time, it will inevitably lead to confusion in thinking, and both production and life and scientific research will be seriously affected. Of the two theories, the theory of relativity is more in line with the so-called common sense, so it is natural for the mainstream scientific community to choose it over Tesla's theory. What's more, Tesla's popularity is so bad

The geomechanical situation of Li Siguang is very similar. No one can prove that it is a wrong theory, and it is indeed useful in practice, but the geological community will never accept the concept that "geological phenomena can be deduced by the method of mechanics", and if it were not for the strong support of the new Chinese government later, Li Siguang's geomechanics is estimated to be not much different from Tesla's theory. Both of them are genius scientists who are not born in the world, and now they are sympathizing with each other, so they naturally see each other at once

Although it is very unpleasant to be left aside, just listening to it is enough to make Hu Weidong realize the extraordinaryness of Tesla, but no matter how high the level is, it will not have much significance for China, which is now weak and backward, and Hu Weidong will only focus on solving practical problems for at least the next ten years. So he quickly and unceremoniously interrupted the conversation between the two genius scientists, "Mr. Tesla, the reason why alternating current is better than direct current is because the voltage of alternating current is easy to increase, which greatly reduces the loss of long-distance power transmission. However, with the development of Shijie economy, the demand for electricity in remote areas will definitely increase, and the transmission distance will naturally continue to lengthen, so the transmission voltage will continue to increase, and with the improvement of wire materials, the resistance loss will become smaller and smaller. Therefore, sooner or later, the loss caused by inductive reactance will exceed the resistance, and direct current has always been superior to alternating current in terms of safety and other aspects, so can I say that as long as the transformer problem is solved, direct current will replace alternating current again? ”

"The outdated way of relying on wires for power transmission will eventually be replaced by wireless power transmission. And wireless 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 Tesla's envisioned wireless power transmission jishu (Note 1) is actually using the resonance effect of the earth's ionosphere, which is not impossible to realize theoretically, but even if this jishu can really achieve ultra-long-distance low-loss wireless power transmission, it will not have any commercial value. Because if this kind of jishu is really practical, it means that any receiving device on the earth can share the power sent by the output device, and if the receiving device is very cheap, with the selfish nature of human beings, most of the power sent will be stolen by people for free. The power supplier will inevitably go bankrupt, and if it is expensive, then the invention will not be promoted at all. Maybe only human beings, uh, probably all human beings have entered society (even if controlled nuclear fusion is successful, power generation and transmission will also require capital investment.) After that. This kind of jishu can really come in handy, right? …,

After hearing Hu Weidong's conclusion, Tesla still stubbornly shook his head and replied. "In the future, human beings will definitely have a way to use all forms of energy, and then the question you mentioned will not be a problem."

When Hu Weidong heard this sentence at first glance, he thought that Tesla was talking about a perpetual motion machine that has failed countless times in history, but there are still people who have succeeded one after another, and he couldn't help frowning, but at this time Tesla explained, "Energy is everywhere and never exhausted, we can't make one calorie of energy become ten calories, but as long as we can make energy transform between various types at a very small cost, for human beings, it is equivalent to having unlimited energy, just like your ancient Chinese saying 'the unity of heaven and man'"

"Why do all these scientific geniuses dive headfirst into philosophy when they are so old? Einstein too, as if Newton was too", Hu Weidong couldn't help frowning, and simply gave a slap in the face, "This is philosophy, the ideal situation, how can it be so simple in reality?" What's more, to put it mildly, who else would study this kind of problem except you? And you are 80 years old, how many more years can you live? Is it time to produce meaningful results? Do you know it's too late? So when you die, there will be no successor to these studies, and you will only be the second Leonardo da Vinci in the future, and you may be able to be amazed by future generations, but how much has you contributed to mankind? At least the rest of your life will be in vain! ”

Tesla didn't make a sound, just grabbed his hair hard

Since he has said this, Hu Weidong simply said his intentions directly, "Most of the Chinese people can't even fill their stomachs now, and the money we have now is all saved by them from between their teeth, if it is not easy to invite you back to China, but you study these useless things all day, then how can we explain to the hundreds of millions of poor people in China who are still hungry and cold?" ”

Note 1: The Tesla coil, which is now very hot, is just a failed work of Tesla at the beginning, and it cannot eliminate the distance energy attenuation, so he later proposed the idea of using the earth's ionosphere, a natural electromagnetic resonant cavity, to realize long-distance wireless power transmission.
