I Build an Aircraft Carrier in the Ming Dynasty

At the exposition, Wu Changqing discovered a lot of good things.

This also strengthened his determination to inspire people's wisdom and rely on private talents to promote the development of science and technology.

Many people are powerful, and even if he has a system, he can't compare with the power of all living beings.

With the popularization of education, more talents will surely emerge from the people.

And he only needs to act as a leader, the responsibility of Mr. Key.

For example, help in some major technological fields.

The last inventor to play was Wu Changqing's student, Fei Yufeng, a genius not inferior to Feng Xianzhong.

A long time ago, Wu Changqing instructed Fei Yufeng to study electricity, and instructed some basic theories and various research directions.

It was almost impossible to directly exchange a generator for him.

However, even with so much help, the process of starting from nothing is still extremely difficult, and it is not enough to explain the various difficulties in one or two sentences.

After more than a year of research, now Fei Yufeng has finally achieved a little success, and was called by Wu Changqing to the expo to show.

Fei Yufeng asked people to bring up some bizarre things that businessmen could not understand.

Then he explained: "In nature, there is a special energy, which is essentially the same as lightning, but the power is far less than that of lightning.

His Majesty named this energy electricity, and electricity is actually everywhere. After the sweater is rubbed, it can absorb some chips, which is a kind of static electricity.

When two dissimilar metals come close together, there is a potential difference between them, resulting in an electric current..."

These words are for the rich businessmen, but they are not.

After all, these words are heavenly to those wealthy businessmen, and they are completely dumbfounded when they hear them.

Fei Yufeng's words are more incomprehensible than Zhang Han, who invented the perpetual motion machine.

Fei Yufeng talked for a long time, but he couldn't come up with "electricity" for everyone to see.

They thought that Wu Changqing would soon have Fei Yufeng taken away.

However, they miscalculated again.

Wu Changqing listened patiently. When other wealthy businessmen saw Wu Changqing's appearance, they quickly followed and listened seriously.

Even if you don't understand it, at least it looks like you have to do it.

Otherwise, wouldn't it be telling others that you don't understand and telling others that you are a fool?

After Fei Yufeng explained it, he officially started the demonstration.

What he came up with was a voltaic pile.

Mix some paper soaked in salt water between different metals, and a potential difference will be generated between the two metals. Then when multiple of these are stacked together, the potentials can add up to a considerable degree.

This is the so-called electric stack, and it is also the most primitive battery.

Through the voltaic stack, Fei Yufeng obtained a relatively stable weak current. When these currents passed through the tungsten wire with extremely high resistance, the tungsten wire emitted a weak red light.

At this point, after the demonstration was over, the merchants were stunned.

That's it? That's it?

After talking about so many mysterious and mysterious things, finally came up with such a weak reaction?

They wanted to take off their size 42 cloth shoes, pointing to Fei Yufeng and asking, what's the use of this thing.

It was just that faint red light, which was 108,000 miles away from the kerosene lamp.

How simple and beautiful are the kerosene lamps.

And Fei Yufeng's voltaic pile is ugly in appearance and huge in size.

In any way, this thing can't compare with a kerosene lamp.

In addition to lighting, the wealthy businessmen couldn't think of anything else that this thing could do.

After all, after Fei Yufeng talked about the book for a long time, he only changed a little bit of metal.

This is simply less reliable than the person who invented the perpetual motion machine.

Zhang Han, at least the prospect outlined is very grand, to completely replace coal and horses, it sounds lofty.

The reaction of the wealthy businessmen fell into Wu Changqing's eyes, but he was not surprised.

If a scientific research result can be easily understood by ordinary people, then this kind of thing has long been discovered, invented and used.

It is precisely because electricity is too ethereal, invisible, and palpable. It is difficult for ordinary people to understand, so the development will be so slow.

The voltaic pile was invented in 1800, but it took Ferrari 51 years to use the magnetic field effect to generate the induced current.

Another example is Henry who discovered the principle of radio in an experiment, but he, a scientist who studies electricity, did not realize how important this technology was.

Now these businessmen only see the most primitive batteries, and it is normal to disagree.

Fortunately, Wu Changqing knew the importance of electricity.

Therefore, he will start to encourage more people to study this electricity from now on.

From the discovery of electricity to the use of electricity, this process is a long process, which requires constant and vigorous promotion, and continues to provide support in the days when there are no results.

Only in this way can we strengthen the confidence and enthusiasm of those who study electric power and accelerate the development of electric power.

With enough support, it would not have taken 51 years to go from a voltaic pile to electromagnetic induction.

The support of the emperor is the most reassuring.

Therefore, Wu Changqing said: "This is what I have seen so far.

The most important discovery, far-reaching and significant. "

His first sentence shocked the wealthy businessmen and other officials. This evaluation was too high.

So high that others will doubt whether Wu Changqing is favoring Fei Yufeng.

After all, even if this thing is useful, it can be more powerful than a steam engine?

The current consensus in Dahua is that the steam engine is the most powerful and the most important.

What is this stack in front of you? Can you pull the train? What a joke.

However, since the emperor said that it is of great significance, then it is of great significance, and no one is stupid enough to argue with the emperor.

Anyway, as long as they don't pay for it, everything can be said.

And what kind of electricity research wants them to pay, that is, they can't agree.

And Wu Changqing just expressed his attitude.

Just let everyone know that you take this research seriously.

He would pay for the funds needed for research in electricity, and he did not count on other businessmen with limited vision.

And for the things he privately financed, part of the profits will go into his pockets in the future.

It is because of these income that his private house money has always been abundant.

Private house money is also very important, and it is easy to do things if you have money.

For example, if he thinks of holding a science and technology expo, he should do it immediately, without having to ask the cabinet to discuss it, because he pays for it and belongs to his private affairs.

It will cost Wu Changqing a lot of money to hold this science and technology expo, because in the next step, these inventions will be scored, and outstanding inventions will be awarded awards and bonuses.
