Yang Tiansheng, the second cabinet minister, and Yang Chengxin, the cabinet minister, went out together, and Yang Tiansheng invited Yang Chengxin to ride in his new carriage together, and Yang Chengxin accepted his kindness.

Both of them are surnamed Yang, five hundred years ago was a family, but there is no relationship between them, they are related to Fujian Province, Yang Tiansheng ancestral home in Fujian Province, Yang Chengxin is Futai in Fujian Province, climb the relationship, and get closer.

The first assistant Ma Shiying has a close relationship with Ruan Dacheng, so two mountains have been formed, as for Du Yinxi, he is a lonely minister, and the two are not partial, it is the personnel arranged by Yan Changwu, and the government is balanced.

In the army, soldiers come from all over the world, and even though the navy has a large number of military personnel in Min, there are also a lot of officers from other provinces.

Although they do not have the right to approve the red, they have a lot of power in the intelligence system, and the intelligence system itself is in opposition to the civilian officials.

The new dynasty does not use TJ to govern, but TJ participates in the intelligence system and restrains civilian officials.

Zhu Zhenzhen is a female generation, without a husband by her side, and has lost the help of the emperor's relatives and relatives, she can stand in the civil power of the Manchu Dynasty, there is no chaos between the government and the country, relying on the control of the army, although the civilian officials have the military department, but only manage the military and politics, and are greatly restricted, personnel rights, financial power are in Zhu Zhenzhen's hands.

The Imperial General Staff was established, which was responsible for commanding the national army and holding military orders, and the General Staff was directly subordinate to the princess and was not under the jurisdiction of civilian officials!

The people of the time thought that although Yan Changwu was a pirate, he knew that good political affairs must not be balanced, and he acted with sophistication, which was better than Emperor Chongzhen, who killed TJ as soon as he ascended the throne and became lame.

Liang Yang sat in the carriage, Yang Cheng found that the newly bought carriage was more spacious, the shock absorption effect was good, and its design was ingenious, which was amazing.

There is a windward wind tunnel to bring in fresh air in the carriage, and there are water-cooled seats!

The water-cooled seat is a water tank on the car, and the key is the fan installed in the car, which moves against the wind to provide power, and drives the gears to agitate the propellers in the water flow, so as to drive the water flow to circulate and take away the heat.

Copper pipes are laid behind the seats, and the deluxe version of the carriage also has copper pipes on the top of the seats, which contain water and connect to the water tank.

"If you want to enjoy it even more, you can add ice to the tank!" Yang Tiansheng's words lightly made Yang Chengxin greatly admired.

In ancient times, there were two methods of taking ice, one was to store ice, and the other was to make ice.

Let's talk about the first kind first, in the 39 days when the weather was cold and frozen, the ancients used ice hammers to cut the ice into pieces on the river surface, each piece can bear the weight of people, but at this time they do not take out the ice, but let it continue to freeze, because the ice cut into pieces will float, and the bottom will freeze again after being cold, so there are more thickened ones, and some can even be as thick as one meter, and after the thickness is about the same, people will transport the ice cubes to the cellar dug in advance.

One by one, they had to be stacked from the bottom to the top of the cellar. After the stack is full, cover it with a layer of straw felt, cover it with a thick layer of loess on top of the straw felt, and finally seal the entrance with soil, so that even if the ice cellar is completed, it can be used when it is hot.

Another way to make ice, do not underestimate the wisdom of the ancestors, in the Tang and Song dynasties, people found that putting saltpeter into the water will make the water freeze, so that the ancients learned to make artificial ice, the earliest ice refrigeration originated in China.

The chemical name of saltpeter is potassium nitrate, which is one of the raw materials of gunpowder, it will absorb heat when dissolved in water, the temperature will be reduced, pour some water in a large basin when making, and then put it into a small basin, and pour a basin of water in the small basin, and then pour saltpeter into the large basin, saltpeter absorbs heat, and the water in the small basin will freeze.

After saltpeter is dissolved into water, it can be reused by cooling crystallization method or evaporation crystallization, and there is not much waste.

The production of saltpeter was small in the past, but due to the war between the two Chinas, the demand for black powder was large, and private capital invested a lot in nitrate production and saltpeter, which also led to a surge in saltpeter production and a decline in prices.

With ice, there is the possibility of cooling down and relieving the heat.

Don't look at the simplicity of this kind of carriage, it involves "high-tech" gear sets--- propeller seals, and the use of copper, which can be used as money!

Ancient China has always lacked copper, but in the period of the two Chinas, there was miraculously no shortage of copper.

There is a lot of silver, and people use silver dollars instead of copper plates, and this copper money is saved.

Massive excavation of copper mines, as well as foreign copper!

Now saltpeter has a wide range of sources, and these are the socialized production periods before they can be popularized, otherwise they are only enjoyed by wealthy families and wealthy businessmen.

Nowadays, more and more enjoyment has entered the homes of the general public, and in various cities in China, cold drinks are popular and inexpensive.

The carriage water tank is put in ice, once it starts, the air conditioning comes out from the top of the head, and the seat is cold from the back to the buttocks, and then drink an iced drink, so enjoy!

In winter, there is heating in the car, which is simple, but it is just burning coal to heat copper pipes, plus the matching leather sofa, comfortable!

Such a carriage Yang was born to try it, and next summer, it is ready to be sold in large quantities, which is the "air-conditioned car" of that era!

"Not only sold to private individuals, but also the rental carriages in Nanjing are also ready to use this kind of carriage!" Yang Tiansheng introduced.

"Lao Yang, where did you sell it, I want to have one too!" Yang Chengxin said with interest.

Now the society advocates consumption, stresses enjoyment, and makes life more comfortable, the prince takes the lead, and he himself has ten tons of gold to build Yuejiang Tower and Wanghai Tower, and the subjects are not worried that they will be arrested if they are rich, which is in stark contrast to the big guys of the Chongzhen Dynasty who pretend to be poor.

"It's a subsidiary of Daming North Industries Company that is responsible for production and sales, catch up with Ming'er, I'll send you one, it's not worth a few dollars!" Yang Tiansheng said casually, for a top tycoon like him, a luxury carriage is just a small amount of money.

Daming North Industries Company is actually a North Industries Company from the southeast, which is a first-class military industrial group, Yang Tiansheng is a minority shareholder of this company, and the major shareholder is Jinshang.

Yang Tiansheng said with emotion: "Now that the people's wisdom is opened, the craftsman ability of NORINCO is high!" ”

"Craftsman ability?" Yang Tiansheng tilted his thumb upwards and smiled without saying a word.

"It's actually a ...... today" Yang Chengxin was surprised, and immediately thought that there was indeed this possibility, although Jinshang paid attention to hard work, but also asked for a good life for the people, under his rule, the quality of life of the people continued to improve.

Today, he is full of wisdom and omnipotent, and even if he can't make many technologies, he knows the principles very well, and he can explain a lot of doorways, leading military production and scientific and technological production. It will really be an air-conditioned car produced by him, after all, the "air-conditioned room" is his handiwork.

Of course, Yan Xiaoqiang could not tolerate the lack of air conditioning in the hot summer, so he tried to promote the use of "soil air conditioning".

Outsiders go to the southeast, located in the hot Southeast Asia, there is no winter! But I was shocked to find that I could still be in the coolness, living in an air-conditioned room of a hotel, sitting in an air-conditioned carriage, eating cold drinks, it was unimaginable!

Some wealthy people who have achieved financial freedom are even more air-conditioned, and the middle class is also developing towards air-conditioning, and society is constantly improving.

In the past, the power of air-conditioned rooms came from animal power and manpower, and it was common to use donkeys to pull the turbines.

In recent years, wind power has sprung up, and tall windmills have been erected in open areas, using the wind as the power to divert water towers, provide tap water, and provide the power of air-conditioned rooms!

Its advantage is that there is no need to raise a few more mouths at home, raising livestock is not an easy task, and it needs to be taken care of, and if Ah San lets them do rough work, they will be covered in butter, which is extremely smelly, seriously pollutes the environment, and is not pleasing!

The windmill is of good quality and can be driven day and night for many years, while the man and the donkey have to rest.

Maintenance is also easy and can be done by ordinary people, making it popular.

The impetus for the use of windmills is inseparable from the king of the southeast, and many inventions are from his ideas, engineers and craftsmen to realize.

"Today in the court, it is the blessing of all the people, and the people have a cool!" Yang Chengxin said with his hand.
