Chapter 1021

Wang Yanke shook his head with regret and continued to tell the story of that year: "At the beginning of the discovery of electricity, electricity was still a luxury jewelry in the eyes of people at that time. It was also the privilege of the rich. It was a thing with great commercial potential. Considering the cost of unlimited transmission and other issues, at that time, the wired transmission technology had taken shape, and the business elites naturally chose a wired power supply mode that was easier to master and could sell electricity as a commodity. Among them, there were Edison, the famous great inventor and businessman.

Only directional current supply can be sold as a commodity, and wireless transmission spreads into space like WiFi signals. Once low-cost wireless current receiving technology is popularized, it is bound to lose commercial value.

But Tesla claimed that its technology was to provide free power for the people, so it became a thorn in the flesh of the capitalists. A group of conspirators blocked Tesla's research, so that the project finally stopped after lighting a neon lamp 40 miles away.

The second point is that wireless power supply technology is objectively very difficult. You know, electromagnetic wave propagates outward radially from a point, and its energy, like gravity, attenuates with the square of distance, which is very small beyond a certain distance.

How to solve the large loss of wireless electromagnetic wave in the transmission process is a difficult problem for everyone.

Although Tesla has always insisted that it has solved the problem of wireless power supply technology, in practical action, it has been trying to establish a super high-power transmission source to offset the loss in electrical signal transmission. Power generation was still a relatively high-cost undertaking at that time, and every degree of electricity could not afford to be wasted in the eyes of investors.

As a result, the frustrated Tesla fell into depression for a period of time. Later, his laboratory was stolen and Tesla's manuscript on wireless power supply technology was torn up, which completely put mankind in the earth era on the road of wired power supply.

The whole social public facilities have been developed on the basis of "wired power supply", which once made wireless power supply an "incredible" technological dream in people's eyes. Since then, human science and technology has been entangled and bound by all kinds of pulled wires and switches embedded on the wall, limiting the possible development prospects in many fields.

It was not until the beginning of the 21st century that wireless power supply was picked up by mankind again.

However, at that time, the wireless power supply technology was only limited to point-to-point short-range electric field transmission, the starting point of the technology was low, and the scope of application was also very limited.

Even the charging of a mobile phone should be placed on a specific tool. In fact, it is not much different from wired power supply.

After 20 years of research, a group of scientists at MIT have come up with the concept of wireless power supply with more application value. It denies the previous idea that wireless power supply technology uses pure coupling resonance, but builds a self resonant coil based on coupling resonance, and uses the supporting parasitic capacitance as an amplifier to receive and transmit energy signals , since the quality factor of the self resonant capacitor will be very high, the efficiency of energy transmission will also become greater.

Later, we encountered the doomsday war. After the arrival of the feather civilization, we formed an alliance with the blood moon people. Although the time was very short, in the process of organizing the escape fleet, local scientist Huang Myanmar Yang once conducted special research on a ship star and found that the molecular modules suspended inside it were actually a more advanced wireless power supply technology.

He secretly downloaded a lot of technical materials from the inside of the ship and satellite, and transmitted them back to the headquarters of the country. These technical materials are now applied by our A-star, and wireless power supply has become the basic technology for the construction of public facilities in our society. "

"Your Excellency, the stories you said are really wonderful, but as far as I know, the current wireless power supply technology of our a star is limited to the low-power daily power consumption of civil facilities. Electric vehicles running all over the street is one thing, and space warships are another energy level problem!" Physicist Jason Cole politely and tactfully expressed his views. At the same time, he carefully looked at Li Wei's narrowed eyes. He pushed his glasses on his face, as if thinking about the appropriate words, so he seemed a little too cautious.

Wang Yanke didn't feel annoyed because his idea was doubted. Instead, he nodded at him like encouragement and motioned him to go on.

The physicist looked around the banquet hall and suddenly smiled and asked Wang Yanke, "Your Excellency, did you hear what I just said?"

Wang Yanke was puzzled: "yes, please continue."

"So..." Jason Cole pointed his chin to a soldier standing guard at the door far from the banquet hall. "Did he hear that?"

Wang Yanke looked back at the solemn soldiers standing more than 100 meters away and said with a smile: "you mean that the energy transmission distance is an unsolvable bottleneck?"

"Yes..." the scientist smiled confidently, "just as the transmission of sound attenuates constantly in the air, beyond a certain distance, we lose the significance of transmission. That's why we need radio communication equipment to enhance the warship communication between each other.

There must be two basic problems in the interconnection of energy networks, that is, the problem of "how much" and "how far".

Most of the civil facilities are fixed signal towers, so that the energy can be effectively transmitted between these targets with relatively stable distance, but the warship is a moving target, and... With the acceleration of millions of kilometers and the endurance of hundreds of millions of kilometers, the effective distance transmitted by the energy source is insignificant and beyond our power.

Your idea is really good. The integrated fleet and energy sharing are inexhaustible. Even if a warship is attacked, the main reason for the explosion is that the energy warehouse of each warship is actually an explosive magazine. If the energy carried, whether weapons or power energy, can be used in the instant of attack, It can not only greatly save the combat cost, but also avoid its own destruction to a certain extent.

Unfortunately, this idea is still too advanced. After all, we can't "plug" such a large amount of energy to our comrades in arms in a very short time, and the process from attack to explosion and fire almost happens at the same time. Therefore, this technology can only be a beautiful fantasy for our current fleet construction... "

Wang Yanke also had to admit that this was a key, so he said with a bitter smile: "yes, our wireless energy transmission based on blood moon technology can only cover a range of thousands of kilometers, and the transmission speed is limited. It is a little primitive in front of warships, which have super maneuverability.

But what I mean is that this can become a tough topic for your next research. If you can solve it, it will essentially promote the future combat mode, combat formation and even combat concept of the space fleet... "

"Yes, if it is solved, mankind will get rid of the 1000 year problem of logistics and transportation on the battlefield for the first time!" Li Weigong couldn't help but stand up and round the field, "In the past, the iron rule of 'soldiers and horses do not move, food and grass first' will become history forever. This is bound to become a revolutionary technology to change the basic form of space war. Let's drink to the revitalization of science!"

After that conversation, Wang Yanke never mentioned it to Li Weigong again. The construction schedule of the space fleet was full. Even Li Weigong himself forgot it.

That topic seemed to be the light of Wang Yanke's laughter at the banquet. As soon as she said it casually, everyone echoed it, and no one took it seriously.
