Princess Katrina Kaaf smiled and said, "And that phone!" Qing Guo is still running a telegraph office, and we not only already have telegraph technology, but also telephone technology! ”

President Meng nodded and said: "Yes, this is also one of the most satisfying places for me this time, when Professor Nikola Tesla develops plastics, when the time comes, I want to connect the entire Danzhou to electricity, telegraph, telephone, hundreds of kilometers away, I make a phone call, you can clearly know what I am thinking."

Chief of General Staff Rob Criss admired Xuan Yuemeng's foresight, "President, this not only makes people's livelihood convenient, but also the cross-era progress of the army, with a telephone, the defense can be strengthened several times!" Where it is attacked, it is immediately known, and reinforcements can be sent as quickly as possible, without the need to deploy heavy forces everywhere in wartime. ”

President Meng nodded and said with a smile: "Yes!" Well said! Chief of General Staff Rob Criss, you participated in the American Civil War, and the army and navy are very familiar with it, and you will have to pay more attention to the army construction in Danzhou in the future! ”

Comrade Rob Cles, Chief of the General Staff, was complacent, "Don't worry, President, I dare not say anything else, among the middle and lower-ranking officers in the United States, I have a lot of combat experience." ”

President Meng smiled faintly, a middle and lower-level officer, I can only drag it here, but I can only let you drag it, two years of the army, five years of the navy, even if Danzhou has no military foundation at all, the speed will be doubled, and it should be no problem to cultivate a navy of its own within ten years, the key is still the problem of warships, or the problem of industry!

What if the people who operate train a whole bunch, and then there are no warships? As a colony, how difficult it is to purchase armaments, President Moe has already learned it!

The telephone was invented by the Americans. Two wires are used to connect two transmitters and receivers with the same structure and a vibrating diaphragm on the electromagnet, and the two ends of the communication are realized first.

However, the call distance is short and the efficiency is low.

The charcoal essence microphone greatly improves the efficiency of the telephone transmitter.

The receiver structure has also been improved.

The earliest telephones were magnet telephones, powered by their own batteries and sent call signals by hand-cranked generators.

President Meng needs the technical staff under him to transition the telephone to the common telephone as soon as possible, and change the power supply to the common power exchange, eliminating the need for hand-broadcast generators and dry batteries.

Otherwise, the phones of this era are still battery-powered, the distance is short, the signal is not good, and it cannot be used in a large area!

Rotary dial dial type automatic telephone, it can send out DC dial pulse, control the automatic switch action, select the called user, and automatically complete the exchange function. Thus pushing telephone communication to a new stage.

Not to mention that it suddenly looks like a modern telephone, at least it has to be like Young Master Meng watching a TV series in modern times, with a hand-cranked style!

As soon as possible to develop to the dial-up style, you can promote the whole line, President Meng knows what the telephone opportunity has become, and also saves the process of technical personnel to take a detour, and the telephone is not a high-end technology, President Meng's idea can make the research and development speed of the telephone increase for ten or twenty years!

"President, we haven't named our warship yet!" Princess Katrina Kafu suddenly thought of something and hurriedly reminded President Moe.

President Meng thought for a while, "It's called Danzhou 1872 No. 1, it's easy to remember." ”

Princess Katrina Kaaf nodded, "It's okay, it's easy to remember, but we are just a warship, do we need to call No. 1?" What about number two? ”

President Meng smiled: "I hope there can be a second, if not, it will be called Danzhou 1872 warship in the future." ”

The middle and late nineteenth century was an extremely important stage for the development of the world's ships, and almost all later works on the history of warships and navies will mention this colorful golden age to a greater or lesser extent.

During this period, with the rapid development of the industrial revolution, new technologies and inventions such as steam engines, steel armor, and breech guns continued to emerge, and the wooden sail warships that had dominated the seas for centuries reluctantly began to withdraw from the stage of history in the face of new technologies.

People who are accustomed to admiring sail warships naturally find it difficult to accept this kind of "monster", at first, these strange-looking "magic ships" that spew black smoke and occasionally emit some fire were once used as a joke to laugh at and ridicule after dinner.

In his famous book "Maritime Laborers", which describes the struggle between man and nature, the great French writer Hugo took the trouble to describe all the details of this "magic ship" over and over again, as well as the people's views on it at that time.

This makes it possible for us today to vividly and intuitively understand what happened to the ugly duckling when it came out. As you can see from the book, the great writer was fascinated by the "magic ship", but in those days, there were far more people standing on the shore waiting to see the ugly duckling come out of the ocean than to applaud.

Fortunately, the wheel of history always moves forward, and the ugly duckling will one day become a proud white swan, and the days to come belong to them.

Change seems to have happened overnight, and ship designers from all over the world are somewhat overwhelmed by the new technology, and they must now learn to constantly update their knowledge to meet this unprecedented challenge, or competition.

In this competition, there is no precedent to follow, everyone is groping forward, trying to give full play to creativity and imagination, competing with each other, and occasionally there may be some "piracy" and "plagiarism".

Perhaps it is for these reasons that today's people look back at the warships of that transitional period, and they will feel a little weird, and it is not an exaggeration to describe the various warship designs of this era.

It is precisely with the exploration, development, experience and accumulation of technology in this ugly duckling era that the warship design ideas of various countries gradually matured and unified at the beginning of the 20th century.

Coincidentally, the construction of the Chinese Navy also began in this era of ugly ducklings, and the era when the world's navies were renewing their warships with great fanfare was the age of the Chinese Navy.

Like all warships in that era, the warships of China's modern navy also have a deep imprint of the times, and some of them have special designs that can be used as a model in the history of the development of ships in the world.

In that era, ironclads were undoubtedly the overlords of the seas. This kind of iron-clad warship, which was developed from the battleships of the sail warship era, played the role of the main battle warship in the navy, and was used to participate in regular large-scale naval operations, and was the backbone of the navies of various countries and a symbol of national strength.
