I Build an Aircraft Carrier in the Ming Dynasty

After the successful experiment of wired telegraphy, the military attached great importance to it.

Even if the army clanked badly, they gritted their teeth to support the laying of telegraph lines.

The initial plan was to lay two telegraph lines.

One is from Shanghai, along the Yangtze River to Wuhan, Changsha, and then to Chengdu in the future, connecting all the important cities that pass through.

Another is the north-south direction, from Shengjing to Guangzhou, connecting the important cities along the way.

The two routes form a rough cross, taking care of most of the north and south.

This is the initial plan. In the follow-up complete plan, the military intends to connect all the cities in the country to form a telegraph network.

However, the money required will be astronomical.

The current wire cost is extremely high, and all of it is pure copper, and copper coins are still one of Dahua's important currencies.

The outer layer of insulator is still made of rubber, and the plastic has not yet been made.

And rubber, currently not much cheaper than copper.

Money, money, the military is now thinking about money, and the brain is hurting.

After much deliberation, in the end their solution was to ask Wu Changqing.

After all, not everyone is a bug, and the military's ability to make money is extremely limited.

"Don't give up on your work. Telegrams can not only be used to transmit military intelligence, but also for civilian use. The money you make by collecting telegraph fees can be used to support the laying of subsequent routes."

Wu Changqing showed the military a way. He was annoyed by the military and kept complaining.

No way, Wu Changqing can only point out a way to solve the lack of money.

Although, he also felt that it is best to separate the telegrams used by the military from those used by civilians, and it is easy to cause accidents when mixed together.

However, the current conditions of Dahua are not enough to be so extravagant.

Therefore, Wu Changqing can only take care of the situation first, first for the military and civilians, and then solve this problem when conditions are available.

More importantly, Dahua has no military rivals, and there is no such urgent need for telegrams, but it is more necessary for civilian use.

For example, in terms of train transportation, the current trains can only run once or twice a day, not too frequently.

Because the current train technology is not very mature, basically every week, the train will have a breakdown almost once.

If the trains are too frequent, the train in front breaks down, and the train behind cannot get the news in time, and it will definitely crash.

At present, Dahua's train operation still depends on the post station.

Once the train breaks down, immediately notify the nearby station, and then 800 miles urgently inform the trains behind to suspend the departure.

The speed of information transmission determines the efficiency of rail usage.

With the telegraph, the use of the telegraph to transmit information, then the train can be increased from one or two times a day to five or six times, or even more.

In this way, the transportation volume of goods is directly increased by three or four times, which is quite terrifying, and can greatly reduce the transportation cost.

The reduction of transportation costs is a prerequisite for the prosperity of commercial trade.

In the era of low transportation capacity, the transportation cost often exceeded the value of the goods themselves, so trade was impossible.

The speed of information transfer also has a huge impact on collaboration.

For example, a factory in Shanghai had a broken machine and had to go to Nanjing to buy replacement parts.

Over and over again, you will make a lot of money less by wasting time.

But now, it only takes a telegram to get to Nanjing, and Nanjing can ship it to Shanghai immediately, which can save nearly double the time.

For another example, if the price of a certain commodity in Shanghai has risen sharply in the past, those people have to trot all the way to Nanjing to purchase the goods. If they are late, the price may drop, or they may be preempted by others.

Now, it only takes a telegram to get Nanjing to deliver the goods.

Nanjing and Shanghai are close to each other, so the effect of this accelerated information transfer is not particularly obvious.

When the telegraph station from Nanjing to Beijing is built, the effect will be astounding.

The greater the distance, the greater the role of the telegraph.

In a word, the acceleration of information transmission has a huge effect on development.

Wu Changqing asked the military to put the telegraph into civilian use, but the military was not very happy.

Mixing the two together is prone to some problems. Such as leaks, such as the priority of sending and so on.

In the eyes of the military, national security comes first, and it doesn't matter if the development is slow.

However, they have no choice, who made them poor.

They could only follow Wu Changqing's instructions, seek the cooperation of big businessmen, and work together to make telegrams.

Otherwise, relying solely on the military's own funds, they don't know when and when they will be able to build that telegraph network.

Many businessmen are very interested in this telegram, because they, who do business, understand the meaning of business opportunities too well.

Sometimes, one step ahead of others is a business opportunity.

The advent of the telegraph allowed them to be many steps faster than others.

Therefore, there are many businessmen willing to cooperate with the military, and the conditions given are also very good.

They don't dare to be too greedy when working with the army. After all, the army gives the impression of being unreasonable and violent.

With the participation of businessmen, the development of the telegraph business was much faster.

Today, Dahua's private capital is quite sufficient. As long as there are good projects, there is no need to worry about no investment.

With the use of electricity, there is another emerging industry in Nanjing.

Light bulb factories, wire factories, and telegraph factories were established one after another.

In the university hall, students who have studied electricity have also become fragrant buns for a while.

After all, electricity is quite dangerous.

If you want to play in this industry, you must have professional talents to guide.

Because of the scarcity of talents in this area, when major companies come to recruit people, the wages they give are quite generous.

Those who used to be dismissive of electric power, suddenly regretted their bowels.

The drastic changes in Dahua are too great, but many people can't keep up with the changes.

Electricity is widely used, and most industries can use it to improve efficiency.

However, now that electricity has just appeared, it is impossible to get popularized and used in an instant and directly enter the electrical age.

The current electricity is actually quite expensive, that is, some high-efficiency factories use it.

Ordinary people's homes are temporarily unable to install electric lights.

Price is one aspect, and technology is another aspect.

At present, the power plant can only supply the surrounding electricity, and it will not work if it is far away.

The difficulty of power transmission is proportional to the distance.

If you want to transmit power to a farther place, this involves the technology of using high voltage to reduce resistance. This technology is not as simple as generating electricity.

In short, the current Nanjing can only be regarded as half a foot into the electrical age, but the real electrical age is still far behind.

At present, it is still dominated by steam.
