Once traveling to another dimension of time and space, the first thing the traveler will face are mainly three problems:
1. Basic life security: no need to worry about food and clothing.
Second, protection from the threat of violence. Whether the threat comes from humans or beasts.
3. Protection against the intrusions of nature. Bad weather and disease.
Obviously, most people are more concerned about these immediate issues than the previous overly professional industrial system issues.
Modern society is a highly developed society with extremely detailed and specialized social division of labor. Every convenience in life that people take for granted, even the simplest and most inconspicuous, requires an entire industrial system to maintain. A drop of tap water can be maintained from
Before it was released from the tap, it was supported by many industries such as electricity, chemicals, steel manufacturing, cement, and construction.
In Hainan in the 17th century, none of this existed.
Rice exists in the form of paddy. After simple precipitation of water, the only way to disinfect it is to boil it. There is no concept of ready-made clothes. Rich people can hire tailors, while ordinary people rely on their wives to cut and mend them.
All daily necessities, even the things we are most accustomed to, things that can be obtained cheaply in any small store, did not exist in that time and space, or in other words, existed in an extremely original way.
As the head of the internal affairs team responsible for people's livelihood affairs, Xiao Zishan's proposed equipment catalog caused controversy.
"Is it necessary to bring rice mills, flour mills, and other grain processing equipment? There are issues with spare parts, and power consumption... There were already water-powered rice mills in ancient times, and flour mills were still available to Chinese people in the 1950s.
Many rural people grind their own wheat."
"Well, I think even if mechanized production is really needed, it can be completely made by the mechanical department. It would be a bit of a waste of tonnage to bring it over from this time and space."
"There are also sewing machines, hemming machines, and cutting tools... Team leader Xiao, are you going to open a garment factory or something?"
"The agricultural group firmly supports the need for grain processing equipment! If the internal affairs group doesn't mention it, the agricultural group will also ask for the purchase of these equipment." Wu Nanhai stood on his side, "The processing speed! The traditional method of pounding rice and grinding flour is very inefficient. We
For hundreds of people to eat, manual operation is too labor-intensive."
"You can use water-powered mills. They are also available in China and Europe..."
"Then we have to build a special mill. Not counting the manpower and material resources consumed? If there is electricity, we can directly drive these equipment, and we can process enough grain very quickly."
"These mechanical spare parts problems can be solved by the mechanical department." Xiao Zishan has anticipated the questions that may arise from this problem. Now with Wu Nanhai's explanation, it will be much easier. "In rural areas, dry grains are generally stored. We are a
For Chuanchuan Group, the ration is based on the standards of the planned economy era: 12 kilograms of rice per adult per month. If there are 500 people, at least 6 tons of rice per month will be supplied.
"The ration of 12 kilograms is still the standard for ordinary citizens and employees, and the ration for heavy manual workers will be increased. After traveling through time, there will be a lot of manual labor, and the consumption will have to be calculated based on the figure of 14 kilograms. If we still want to introduce
The supply of local labor force will continue to rise to a higher level.
"The grain processed by the machine is of good quality and will not be mixed with impurities. Stone mills have very high requirements for stone materials. If the quality of the stone is not good, the processed flour will have a lot of debris, which is very bad for everyone's teeth.
"As for the sewing machine, the principle is the same. Sooner or later the clothes will break and need to be replaced. Who do you expect to make the clothes? Your girlfriend? (laughing)
"Perhaps you can hire a local girl. She doesn't know how to make clothes like ours. It's not difficult to teach her how to make clothes, but a purely hand-sewn dress will take several days to make, no matter how skilled you are.
"Of course you may be able to wait for a few days. In the future, we will recruit workers, even," he lowered his voice, "the army." He raised his voice: "The uniform uniforms of these people also rely on the stitches of your wives.
Come out? (laughs)”
"According to what you said, the ancient armies no longer wore clothes. Didn't hundreds of thousands of troops also change their clothes every year?"
"It is built on the basis of having a large amount of cheap or even free labor. We don't have it." Xiao Zishan said sadly, "Our lives are limited, and our productivity must be more focused on climbing the technological tree. Such things are necessary
It’s better to bring the machinery and equipment over directly. We can also provide an engineering sample for future imitation.”
Housing is another issue that everyone is concerned about. The internal affairs team originally planned to purchase a large number of tents and build a tent camp as a transition before officially building houses. The construction team proposed that they purchase simple houses for direct assembly. Such simple houses
It is very common on construction sites - used as dormitories and office buildings. The board materials are of various types and can be purchased according to needs. They are small in weight, easy to set up, have a certain degree of thermal insulation, and are much more comfortable than tents. The durability is also good: if
With proper maintenance, it will last for seven to eight years without any problems.
"A department of our company has been using the simplest color steel prefabricated houses as warehouses and office buildings for almost ten years, and they are still in good condition." The person who made the introduction was Aunt Tian's daughter Li Xiaolu, a thin northern woman.
, almost thirty years old, with fair skin and wearing a pair of thin-rimmed glasses, "It can also be made into a building, but it needs to be added with a light steel structure."
"Because the environment we have to face is relatively harsh," her voice was soft and thin, "we can use higher-end materials, such as phosphorus magnesium mobile houses.
"The walls and roof of this kind of mobile home are made of magnesite composite panels with polystyrene foam pod cores, steel doors and windows, and the frame is light steel keel. No special machinery is required for installation, and skilled workers use simple tools 4
It takes one person 4 hours to assemble a standard room, which is about 60 square meters.
"Its combinability is better than that of a color steel house. You can add or subtract several groups at will in the longitudinal direction. The area can be expanded or reduced at will. The positions of the doors, windows and front and rear wall panels in the house can be interchanged at will. In strengthening the structure
Later, it can also be used to build buildings.
"This kind of house has good sealing, heat insulation, and the house materials are all fireproof materials. It is moisture-resistant, anti-corrosion, earthquake-resistant, and light weight. A standard house weighs only 2,200 kilograms. The expected service life is more than ten years.
“This type of house can be used for dormitories, offices, and small warehouses.”
"What about building factories?" The industrial group is more concerned about this issue.
"If it's a long-span factory warehouse, it won't work, but you can use a simple house made of water-washed stone." Li Xiaolu continued her introduction, "It's actually a cement board simple house with an angle steel structure. It is much heavier than ordinary simple houses. Advantages
It has a lifespan of more than twenty years. It can be assembled into large-span houses and can also be used to build 2-3 storey buildings."
"Cement board..." Someone hesitated.
"The construction team just discussed it and believes that under our industrial system, producing cement and angle steel is not a big problem. If the factory building is not urgently needed, we can just bring the drawings and necessary mold tooling materials and build it ourselves using local materials." Her.
His face was a little pale. "But installing simple houses is a technical job. I suggest that some people be sent to such simple house companies to learn on the spot."
Wen Desi nodded and wrote down something on the memo: "Practical skills training."
“Can water and electricity be installed in a house like this?”
"Yes, although pipes cannot be grooved and buried in the wall, there is no problem in installing them on the wall. However, our construction team's view is that separate water supply and drainage systems should not be installed in dormitories and offices to save materials.
"For water needs, we think it is best to adopt an independent public washroom, including three parts: bathroom, washroom and toilet. This facilitates the centralized installation of water supply and drainage systems. Considering the rainy problem in Hainan, from dormitories, offices to public washrooms
Enclosed corridors will be installed for everyone to use on rainy days. The temperature in Hainan is not low in winter, so systems such as bathroom heating were not considered in the preliminary design."
"What about refrigeration? Hainan is very hot in summer. It needs air conditioning."
Although this person's speech drew a blank stare, many people still longed for air conditioning in their hearts: they were used to using air conditioners, but when they arrived in Hainan in the Ming Dynasty, they didn't even have fans.
"Traditional air conditioning is definitely impossible." Li Xiaolu glanced at Xiao Zishan and saw that the host of the meeting had no objection, so he continued talking, "Traditional air conditioning requires a lot of electricity and chemical refrigerants. It is a luxury for us
A little bit more. If the executive committee finally decides to use air conditioning, we have two options available." She seemed a little dizzy and felt nauseous. She stood holding the table for a while before continuing:
"One is the wet curtain cooling air conditioner. It actually uses an evaporative ventilation fan, eliminating the need for an internal fan and compressor. The refrigerant is water. It saves electricity. The disadvantage is that the humidity is high, and the manufacturing of this ventilation fan is also quite expensive.
Difficulty."
"One is groundwater refrigeration and air conditioning. The principle is similar to that of heating, except that the steam is replaced by groundwater extracted by a water pump. The initial investment of this method is relatively large. Deep wells need to be dug, and the evaporator needs to use copper pipes."
"Personally, I prefer the second one. Its effect is much better than the former one. The system is also relatively simple."
"This kind of air conditioning is not allowed in the country, right? It's a waste of water."
"Damn, there is no such rule in another plane."
"Well, I know that. But wasting water is still the same, and it's not environmentally friendly."
“At that time, did you still care about environmental protection?”
"Groundwater can be reinjected, so there is no waste." She explained, "If you want to be more advanced, you can also use ground energy air conditioning. The method is similar to the second one. Ten meters underground is generally 20 degrees.
Left and right constant temperature state. First reach this depth through drilling, and then use water as a heat exchange medium to circulate underground and in the building to achieve warm winter and cool summer. Heat is taken from the ground in winter and heat is released to the ground in summer. Of course, we
The camp must be on a foundation with a relatively stable geological structure. If it is too active, it will only be able to provide heat."
The attendees all looked at Xiao Zishan, who was in charge of internal affairs, while Xiao Zishan looked at Chairman Wen Desi. From the bottom of his heart, he was in favor of all measures to improve the living conditions of travelers. From frugality to luxury is easy.
He understands the basic truth that it is difficult to move from luxury to frugality. A group of mostly pampered city dwellers go to a desolate place to start over. Living conditions that are too difficult will cause low morale.
However, he did not dare to openly express his opinion. Such a living system would involve the use of a large amount of industrial resources, and he really did not have the courage to express his approval for this.
Wen Desi made eye contact with him for a long time, then looked at the leaders of each group for a long time, and finally said a classic line:
