Chapter 811 Difficulties
The "small technology" that Jiang Cheng plans to study this time is actually not simple at all.
Because this technology is called "wireless power transmission technology", it is a very important technology for human beings.
Wireless power transmission technology refers to the ability to transmit power from a power 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 big 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 reach the midrange of the public.
Imagine how convenient it is that your computer can be turned on directly without wires.
When this technology is popularized in all home appliances, there will be no such thing as wires in the home.
Just install an electrical energy delivery device in your home, and you can use all household appliances.
In the future, there will be no wires at home, and the whole environment will become much cleaner.
Maybe those electrical appliances that are originally fixed, still can't see the advantages of this technology.
But if you put this technology on a mobile device, the advantages are immediately reflected.
Mobile devices that can be used at any time have to be recharged frequently due to power problems.
If you want to use your mobile device while charging, you must use it with a charging cable.
Mobile devices can't move 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.
In the future, people will no longer have to worry about the problem of electric energy, and the level of convenience has been improved.
The mobile phone is 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 to limit your activities to a very small extent.
Even if you want to go to the place with your mobile phone, you have to suspend charging.
It's not very convenient in any way, and it's uncomfortable to use.
If the mobile phone has the function of wireless charging, you will never 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 ask Ruo Jiangcheng to sell them the authorization to use this technology.
At that time, Jiang Cheng only needs to sit at home, and he will be able to rely on this technology to continuously make money.
In fact, these civilian applications are not the main purpose of Jiang Cheng's development of this technology.
What Jiang Cheng values most is the application of this technology in aerospace. Laying wires on Mars is a very troublesome thing.
Next, cities will be built on Mars, and many of the devices used will need electricity to supply them.
If all these devices are powered by wires, the laying of the wires is 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 doesn't have to worry about the energy supply of those devices on Mars.
Jiang Cheng only needs to install a receiving device on all the equipment, and then put a large-scale 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 in this spare time.
As for the subsequent use of this technology to make money, it is just a side benefit.
In fact, wireless power transmission technology has long been proposed, but it has not been realized.
As early as 1889, someone proposed the idea of wireless power transmission.
So this technology is already the old calendar of the last century, and it is nothing new at all.
However, this technology has been proposed for hundreds of years, but no one can solve it until now.
It was Nikola Tesla, the legendary engineer, who proposed wireless power transmission technology.
When he was in 18XX, he put forward the idea of wireless power, and also conducted experiments, but the final experiment failed.
There are rumors that Tesla has solved the problem of wireless power transmission technology, but because of external pressure, it temporarily abandoned this plan.
Others said that Tesla also left the technical drawings of wireless Handian, but they were completely destroyed.
There are too many legends about Tesla, and Shin doesn't know if it's true or not.
The black technology proposed by Daisla is not the same. It is rumored that many of his technologies have surpassed this era, and have reached the level of being feared by the country.
Therefore, many of Tesla's research results were destroyed, including this wireless power transmission technology.
But Jiang Cheng would not care about Tesla, an engineer, whether he had developed this technology at the time.
Anyway, even if he really developed this technology, it was not handed down in the end, and humans still haven't solved this problem.
For Jiang Cheng, this is a new technology and a new challenge.
Lucy, help me find all the papers on wireless power transmission technology, let me first look at the previous research results. "Jiang Cheng stood in the laboratory and said to Lucy.
Before Wakasho researched wireless power transmission technology, Jiang Cheng routinely looked at other people's research materials.
He is ready to learn from these failures so that he can prepare himself for 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 impossible to use.
It's just that when those technologies transmit power, too much power is wasted.
With the wireless power transmission technology developed by many people, at least half of the electric energy has to be wasted before it can be accepted in the end.
The wireless transmission technology that wastes more than half of the electric energy has no possibility of being put into use, so the research of these people 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 it, loss is inevitable.
Whether it is an electromagnetic wave or a ground wave, it will naturally attenuate when it propagates in the air.
When the power transmission device sends out the power, after the consumption in the air, the receiving device will naturally lose a large part of the power when it gets it.
What's more, the propagation of electromagnetic waves will also spread, so that the received electric energy will lose a part.
After such a consumption, the power loss of wireless power transmission is too large.
