Chapter 568： Voltaic stack

At the fair, Wu Changqing found a lot of good things.

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

There are so many people and powerful, even if he has a system alone, he can't compare to the power of all living beings.

As the popularization of education continues, more people will surely emerge from the public.

And he only needs to act as a leader, Mr. Key's responsibility.

For example, provide assistance in some major scientific and technological fields.

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

A long time ago, Wu Changqing pointed Fei Yufeng to research on electricity, and guided some of his basic theories, as well as 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 scratch is still extremely difficult, and it is not possible to explain the various difficulties in one or two sentences.

After more than a year of research, today's Fei Yufeng is finally a little bit successful, and Wu Changqing is called to the expo to show it.

Fei Yufeng brought up some weird things that merchants couldn't understand.

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

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

If two different metals are close together, there will be a potential difference between them, which will generate electric current..."

These words are for those wealthy businessmen, but they are not.

After all, these words are heavenly books to those wealthy businessmen, and they are completely confused.

Those words of Fei Yufeng are more difficult to understand than those of Zhang Han who invented the perpetual motion machine.

Fei Yufeng talked for a long time, and couldn't bring out some "electricity" to show everyone. It was just a vain concept and it was too much brainstorming.

They thought that Wu Changqing would soon let someone take Fei Yufeng away.

However, they miscalculated again.

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

Even if you don't understand, but at least do it.

Otherwise, don't you tell others that you don't understand, tell others that you are a fool?

After Fei Yufeng gave some explanations, the demonstration officially started.

The thing he made was a voltaic stack.

If some paper soaked in salt water is mixed between different metals, there will be a potential difference between the two metals. Then after stacking multiple such things together, the electric potential can be superimposed to a considerable degree.

This is the so-called stack, which 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, the demonstration was over, and the merchants looked dumbfounded.

That's it? That's it?

Having said so many mysterious and mysterious things, in the end he made a weak reaction like this?

They wanted to take off their 42-size cloth shoes, pointed at Fei Yufeng and asked what's the use of this stuff.

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

The kerosene lamp is so simple and beautiful.

Fei Yufeng's voltaic stack is ugly in appearance and bulky.

No matter how you look at it, this thing cannot be compared with a kerosene lamp.

In addition to lighting, the wealthy businessmen can't think of any other effects this thing can do.

After all, Fei Yufeng only changed a small piece of metal after talking about it for a long time.

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

Zhang Han, at least outlined a grand prospect. He wanted to completely replace coal and horses, which sounded lofty.

This reaction of the wealthy businessmen fell in Wu Changqing's eyes, but he did not have many surprises.

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 because electricity is too vague, invisible and tangible. It is difficult for ordinary people to understand, so development is so slow.

The voltaic stack was built in 1800, but in the next step, Ferrari used the magnetic field effect to generate the induced current. This process took 51 years.

For example, Henry discovered the principle of radio in an experiment, but he, a scientist who studies electricity, didn't realize how important this technology is.

Now these merchants only saw the most primitive battery, and it was normal to disagree.

Fortunately, Wu Changqing knows the importance of electricity.

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

The process of discovering electricity, and then using electricity, is a long process and requires constant vigorous promotion and continued 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.

If there is enough support, it will not take 51 years to go from voltaic stacks to electromagnetic induction.

The emperor's support is the most reassuring.

Therefore, Wu Changqing spoke: "This is the most important discovery I have seen so far. It has far-reaching and important significance."

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

So high that everyone would doubt whether Wu Changqing was partial to Fei Yufeng.

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

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

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

However, since the emperor said it was of great significance, then it was of great significance, and no one was so stupid that they had to argue with the emperor.

Anyway, as long as you don't want them to pay, you can say anything.

And what kind of electricity research wants them to pay, that is, it is absolutely impossible to agree.

And Wu Changqing just expressed his attitude.

Let everyone know that you attach great importance to this research.

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

And for his privately funded things, part of the future income will also go into his pockets.

It is precisely by these benefits that his private money has always been abundant.

Private money is also very important. It is easy to do things if you have money.

For example, if you think of holding a science and technology expo, do it right away, and you don't need to ask the cabinet to discuss it, because he pays his own pocket and is his private business.

It will cost Wu Changqing a lot of money to run this science and technology expo, because the next step is to give scores to these inventions, and award prizes and bonuses to outstanding inventions.
