Chapter 811 Difficulty

The "small technology" Jiang Cheng plans to study this time is actually not simple at all.

Because this technology is called "wireless power transmission technology" and it is a very important technology for mankind.

Wireless power transmission technology refers to the ability to transmit power from a generating device to a receiving device without using electricity.

To put it bluntly, electricity can be transmitted without wires, completely eliminating the constraints of wires.

If wireless power transmission is truly realized, it will not only play a great role in industry, but also in the civilian field.

Just the fact that all household appliances can be used directly without wires is enough for this technology to gain popularity among the public.

Imagine that your computer does not need wires and can be turned on directly when you put it there. How convenient this is.

When all home appliances adopt this technology, there will no longer be such things as wires in the home.

As long as a power delivery device is installed at home, all household appliances can be used.

From now on, there won’t be a single wire in the house, and the whole environment will become much cleaner.

Maybe those electrical appliances that are originally designed for the same purpose still don’t see the advantages of this technology.

But if you put this technology on mobile devices, the advantages will be immediately apparent.

Mobile devices that can be used at any time have to be charged frequently due to power problems.

If you want to use a mobile device while charging, you must connect it to a charging cable.

The mobile device cannot be moved at all while charging, which is a big problem.

When a mobile device is equipped with a wireless power transmission device, it can be carried around while charging.

From now on, people will no longer have to worry about power issues, and the convenience has improved tremendously.

Mobile phones are the best example. When the mobile phone is charging, if you want to use the mobile phone, you have to drag a long charging cable, which limits your range of activities.

Even if you want to go somewhere with your phone, you have to stop charging it.

This is inconvenient to say the least and makes people very uncomfortable to use.

If your mobile phone has a wireless charging function, you will no longer have to worry about this problem in the future.

Even when charging, you can walk around with your phone without worrying about charging.

If Jiang Cheng really develops this technology, he can definitely make a lot of money from it.

Those home appliance manufacturers will come to Ruojiang Cheng and sell them the license to use this technology.

By then, Jiang Cheng will be able to make a steady stream of money relying on this technology just by sitting at home.

In fact, these civilian applications are not Jiang Cheng's main purpose in developing this technology.

What Jiang Cheng values ​​most is the application of this technology in aerospace. Laying wires on Mars is a very troublesome matter.

Next, when building a city on Mars, many of the equipment used will require electricity.

If all these devices were powered by wires, the laying of the lines would be a big problem.

Setting up a power transmission line on Mars is much more difficult than on Earth, and there are many more issues to consider.

If there is wireless power transmission technology, the problems of these lines will not exist.

As long as wireless power transmission technology is developed, Jiang Cheng will not have to worry about the power supply of the equipment on Mars.

Jiang Cheng only needs to install a receiving device on all equipment, and then place a large power transmission equipment in the base, and the energy supply problem of all equipment will be solved.

It is precisely because of this very real problem that Jiang Cheng is planning to develop this technology during this free time.

As for the later use of this technology to make money, it is just a side benefit.

In fact, wireless power transmission technology has been proposed a long time ago, but it has never been realized.

As early as 1889, someone proposed the idea of ​​wireless power transmission.

Therefore, this technology is already an old almanac from the last century and is not a new thing at all.

However, this technology has been proposed for hundreds of years, but no one has been able to solve it until now.

It was Nikola Tesla, the legendary engineer, who proposed wireless power transmission technology.

In 18XX, he proposed the idea of ​​wireless communication and conducted experiments, but the final experiment failed.

There are rumors that Tesla has solved the problem of wireless power transmission technology, but due to external pressure, it has temporarily abandoned this plan.

Some people also say that Tesla also left behind technical drawings of wireless communication, but they were completely destroyed.

There are so many legends about Tesla that Jin doesn’t know whether this is true or not.

The black technologies proposed by Silla are no longer the same. It is rumored that many of his technologies are beyond this era and are already feared by the country.

Therefore, many of Tesla's research results were destroyed, including this wireless power transmission technology.

But Jiang Cheng didn't care whether Tesla, an engineer, had developed this technology at that time.

Anyway, even if he really developed this technology, it was not handed down in the end, and today's humans still have not solved this problem.

For Jiang Cheng, this is a brand new technology and a brand new challenge.

Lucy, help me find all the papers on wireless power transmission technology so that I can take a look at the research results of predecessors. "Jiang Cheng said to Lucy while standing in the laboratory.

Before he started to study wireless power transmission technology, Jiang Cheng routinely read other people's research materials.

He was ready to learn from these failures to prepare for his own success.

After reading all the research materials of his predecessors, Jiang Cheng understood why those people failed.

The biggest problem with wireless power transmission technology is that the loss is too great during power transmission.

In fact, the wireless power transmission technology developed by others is not unusable.

It's just that those technologies waste too much electricity when transmitting electricity.

Many people have developed wireless power transmission technologies, and at least half of the electricity must be wasted before it can be accepted.

To waste a lot of Semi-powerful wireless transmission technology has no possibility of being put into use, so these people's research finally failed.

The most difficult part of wireless power transmission technology is how to reduce consumption.

If you want to convert electrical energy into waves and then transmit them, losses are inevitable.

Whether it is electromagnetic waves or pure waves, they will naturally attenuate when propagating in the air.

When the power transmission device sends out electricity, it will be consumed in the air, and the receiving device will naturally lose a large part of the electrical energy it receives.

What's more, the propagation of electromagnetic waves will also spread, so the electrical energy that can be received will be lost again.

After such consumption, the electrical energy lost by wireless power transmission is too large.
