James Watt built the first practical steam engine in 1776, which ushered in the age of steam.

In the fifth year of the double holiday calendar, benefiting from the development of casting technology, especially steelmaking technology, Ge Lipeng, whose name is Watt, also began to develop and produce steam engines.

At this time, a full year had passed since the end of the Great War, which was called the War of Unification by mainland historians.

Ge Lipeng stepped down from his post as director of the gun factory, because he still preferred to make civilian inventions rather than making weapons.

It just so happened that Lu Weijia found the coal mine near Black Rock City not long ago, and after a simple exploration, he found that the coal seam there is thick, the coal quality is good, and the geological structure is also simple, and the cutting and mining ratio is high, which is a very good minefield.

Ge Lipeng felt that the time was almost ripe, so he planned to move the steam engine to the continent of Brattis.

The principle of the steam engine is so simple that even junior high school students can understand it.

It is nothing more than boiling water through a boiler to generate steam, and then the steam pushes the piston to do work, replacing manpower or animal power.

However, the production of steam engines, especially those that can be put into operation, is a long-term and complex task.

Until Ge Lipeng's crossing, improving the thermal efficiency of internal combustion engines was still the direction of many scientists' research.

The thermal efficiency of ordinary internal combustion engines is between 40% and 60%, and the steam engine is even lower, even if it is a multi-expansion steam engine, it is only in the early 20%, compared to the permanent magnet synchronous motor can achieve more than 90%.

Of course, theoretically speaking, if you know the production method of batteries and motors in advance, you can also skip the invention of the internal combustion engine and step into the electric age.

But even on another level, most of the electricity used in modern society still comes from the combustion of the internal combustion engine, which can be said to be ubiquitous.

Obviously, the continent of Brattis also needs an internal combustion engine.

Fortunately, now Ge Lipeng has a lot more helpers around him, and after realizing that the humans on the other side can no longer be reincarnated, most of the more than 100 people brought by Li Yu have chosen to join the Shuangxiu Sect, abide by the precepts, and become true believers on Saturday.

With the help of these physicists, chemists, and engineers, the first steam engine rolled off the assembly line in less than half a month.

And unlike James Watt's zero, this one by Ge Lipeng and his research team is significantly more efficient.

And with the internal combustion engine, it's hard not to try to hang a carriage behind it and lay rails on the ground, so the first train on the continent of Brattis appeared half a year later.

It runs a short distance, only about 30 miles from the coal mine to the steel plant.

However, on the day when the railway was laid, many people came.

Even Queen Victoria was so shocked that she rushed back from the royal capital after hearing the news and cut the ribbon for the train herself.

After that, the big guys sat together in the big wooden bucket that pulled coal, and the small train suddenly emitted black smoke, and drove from the Holy City Iron and Steel Plant to the Ping'an Coal Mine under the gaze of the onlookers, without any failure along the way.

After arriving at the destination, there was a long applause around them.

Although the big guy has seen a lot of miracles of the Shuangxiu Sect over the years, especially the people living in the green area, they are a little accustomed to this.

But it doesn't need to be pulled by horses or other livestock, and the car that can run on its own is quite impressive.

After the experience, Miss Rabbit felt that although the small train was not as fast as the horse in terms of speed, it was better to last, and it was eye-catching enough, but it was a bit expensive for passengers.

The black smoke in front of me kept drifting into the nose, and the wind was quite strong.

Ge Lipeng explained that this is because this small train is intended to be used to transport coal, and there will be a train that can really seat people in the future, and there will also be a roof, and the design of the roof will be as aerodynamic as possible, which can also reduce some energy consumption.

Ilea expressed her anticipation, and for the past two years, Miss Rabbit has been leading her army to fight abroad, and after defeating the dwarves and elves, and completely unifying Brattis, she returns to Lionheart to handle government affairs.

After working for more than half a year, she didn't have time to return to her hometown until the situation in the empire had completely stabilized.

As the first territory of the Arias family and the origin of the Shuangxiu Religion, Green Field has developed the most rapidly, almost every day.

When Miss Rabbit came back, she was almost unrecognizable, and now the green field is full of brick houses, neat and tidy, whether it is a city or a village, it looks very neat, unlike other places, you can't see the feces of people and animals.

In addition to the fact that the Hughes of the Shuangxiu Church have been educating about hygiene, it is also because the local farmers have tasted the sweetness of composting.

The demand for fertilizer is high, which makes the stool that was originally disliked also valuable, and some people even run to the pit in the middle of the night to steal manure.

In addition, the new town, which was named the Holy City, was paved with floor tiles, a movie theater, a bathhouse, a school, a house of worship, a sports field, a shopping street, and ...... It can also be said that it has everything.

Moreover, in the early days, Li Yu used the blood of the dragon (sildenafil), white paper, and low-cost linen cloth to make a commercial name for the new city, and caravans from all over the country flocked to the green field.

Later, new products such as glass, porcelain, soap, perfume, and dyes began to be launched, and now the holy city has become a trade center in the west, and even those merchants from other countries have heard of it.

Even at the cost of war, they have to travel thousands of miles to come here to buy goods.

In addition, Shuangxiu Education also used this place as a pilot to build 12 primary schools in one go, and began to fully implement three-year compulsory education to cultivate basic literacy and arithmetic skills.

Children over the age of six can enroll for free of charge, not only free of tuition, but also three meals a day, which alone saves parents a lot of money in child support.

Children at this age are not laborers themselves, and even if they are given to others as servants or apprentices, they are at most in charge of food.

In contrast, the environment and food are much better when sent to primary school, and there are more jobs to be done after learning to read.

In addition to the train, Ilea also took a test ride in a hot air balloon, of course, for safety reasons, she did not fly too high, only about two meters above the ground.

In the afternoon, I went to enjoy a football match, and after this set of entertainment, Miss Rabbit suddenly didn't want to go back to the royal capital, and even didn't want to be the queen.

How can there be happiness from resting at work, not to mention that others are getting poorer and poorer, only Miss Rabbit's battle is getting richer and richer, after the unification of the mainland, Ilea has been completely free of wealth, and there is not much enthusiasm left to go to work.

That is, she has only been crowned for a long time, and now she is burdened and begins to enjoy life at a young age, which is a bit unusual.

Therefore, Miss Rabbit can only resist the impulse in her heart, touch the fish for a few more years, and cultivate the heir by the way, and then go back to her hometown to lie down and enjoy herself.

But Li Yu didn't know when she would come back and have a baby with her, and Elija thought that it was not a way to wait, so she had to be positive, otherwise it would be too cost-effective if she really accidentally worked to death in the queen's position.

Ilea's gaze circled, and finally fell on her squire, Albus.

"Do you have any commands?" Albus said busily when he saw the queen looking at him.

"I remember that you are illiterate, and you are also a nobleman, which is not good."

Miss Rabbit said with a straight face, "Since Shuangxiu has opened an elementary school, you should also go to school." ”

"Huh?" Albus didn't know why Ilea suddenly sent him to be a primary school student, he was actually a bit older in elementary school.

"Well, you can follow me to the Imperial Council after you are done." Ilea ignored Albus and said to herself, "Then you go to Quintus Hughes, I heard that he is compiling the Prophets, and he is short of manpower. ”

Albus was completely confused, not knowing how Quintus could help with the compilation of the Prophets, but he complied with the Queen's orders.

Miss Rabbit is satisfied, this person who doesn't top the tank has it.
