Chapter 839

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

Because this technology is called "wireless transmission technology", which is a very important technology for human beings.

Wireless transmission technology means that power can be transmitted from the generating device to the receiving device without using electricity.

To put it bluntly, power can be transmitted without wires, completely eliminating the restriction of wires.

If the real realization of wireless power transmission, not only in the industry has a great role in the civil field can also have a great deal.

All household appliances can be used directly without wires, which is enough for this technology to be widely used.

Imagine how convenient your computer can be turned on without wires.

When all the home appliances have popularized this technology, there will be no wires in the home.

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

In the future, there will be no need for a single wire in the home, and the whole environment will become more and more refreshing

maybe those electrical appliances that are originally set in the same way can not see the advantage of this technology.

But if we put this technology on mobile devices, the advantages will be reflected all of a sudden.

Mobile devices that could be used at any time have to be charged frequently because of power problems.

If you want to use a mobile device when charging, you must use a charging cable.

Mobile devices can't move when charging, which is a big problem.

When a mobile device is loaded with a wireless power transmission device, it can be charged and carried around.

In the future, people will no longer have to worry about the problem of electric energy, and they don't know how much the convenience has been improved.

Mobile phone is the best example. When charging a mobile phone, if you want to use a mobile phone, you have to drag a long charging cable to limit your activities.

Even if you want to take your cell phone to a place, you have to stop charging.

It's not very convenient. It's very uncomfortable to use.

If the mobile phone has the function of wireless charging, it will not have to worry about this problem in the future.

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

If Jiang Cheng really develops this technology, he will surely make a lot of money on it.

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

At that time, Jiang Cheng just needs to sit at home and can make money continuously by this technology.

In fact, these applications in the civil field are not the main purpose of Jiangcheng's development of this technology.

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

Next, we will build cities on Mars, and many of the equipment we use will need electricity.

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

It is much more difficult to set up a transmission line on Mars than on earth, and there are many more problems to consider.

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

As long as the wireless power transmission technology is developed, Jiang Cheng won't have to worry about the energy supply of those devices on Mars.

As long as Jiangcheng installs a receiving device on all the equipment, and then puts a large power transmission equipment in the base, the energy supply problem of all the equipment will be solved.

It is because of this very practical problem that Jiang Cheng is ready to develop this technology in his spare time.

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

In fact, wireless transmission technology has long been proposed, but it has not been realized.

As early as 1889, someone put forward the idea of wireless transmission.

So this technology is the old almanac of the last century. It's nothing new at all.

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

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

At the beginning, in 18xx, he proposed the idea of wireless power, and also carried out experiments, but the final experiment failed.

It is rumored that Tesla has solved the problem of wireless transmission technology, but because of external pressure, it has temporarily abandoned the plan.

Others said that Tesla also left the technical drawings of wireless power, but they were completely destroyed.

There are so many legends about Tesla that Jin doesn't know whether it's true or not.The black technology proposed by Tesla is not the same. It is said that many of his technologies are beyond this era and have reached the level of being feared by the state.

So many of Tesla's research results were destroyed, including the wireless transmission technology.

But Jiang Chengcai won't be in charge of Tesla. Did he develop this technology at that time.

Anyway, even if he really developed this technology, it didn't survive in the end. Today's human beings 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 about wireless transmission technology. Let me look at the previous research results first. "Jiang Cheng stood in the laboratory and said to Lucy.

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

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

after reading all the previous research materials, Jiang Cheng will understand why those people failed.

The biggest problem of wireless transmission technology is that the loss of power transmission is too large.

In fact, the wireless power transmission technology developed by others can not be used.

It's just that when those technologies transmit electricity, they waste too much power.

The wireless power transmission technology developed by many people will waste at least half of the power before it can be accepted.

Wireless transmission technology, which wastes more than half of its power, is not possible to be put into use at all, so these people's research failed in the end.

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

If you want to convert electric energy into waves, and then in the transmission, loss is inevitable.

Whether it is electromagnetic wave or penetrating wave, it will naturally attenuate when it propagates in the air.

When the power transmission device sends out power, through the consumption of air, the receiving device gets power, which will naturally lose a large part.

What's more, the propagation of electromagnetic wave will also spread, so that since then, the electric energy that can be received has lost a part.

After such a consumption, the power lost by wireless transmission is too much.
