After Zhou Laosan was taken out, Xiao Jing made a summary of the interrogation just now. "I think the new world we want to cross is still the earth, although there is a certain deviation in the place name and race, but I think the overall will not change too much, at least the Chinese mainland we are going to will not change, then we need to choose a suitable place for development as our base, you can discuss later which place is more suitable." In addition, as a means of transporting a large number of people and machinery and equipment, we can only choose large freighters, and as an escort, we have to purchase some small ships for escort purposes. ”

Most of the audience nodded, and Bu Zhongfu from the sports group put forward his opinion, "On the issue of escort ships, we can find a way to buy retired ships of the Navy, as military ships, it is much better to maintain these things than ordinary civilian ships, and the Navy also has many fishing boats." Even if you buy those fishing boats, they can be used as warships from another time and space with a little modification. ”

"And how to solve the problem of artillery?"

"That is, we only have light weapons, even if we can maintain fire suppression at three or four hundred meters on the sea surface, we can't resist the artillery of the enemy's navy!"

Gu Fulin smiled mysteriously on the side, "Everyone has seen too much of the Beiyang Sailors, right?" The artillery range of the Ming Dynasty was very short, even the maximum range of the Hongyi cannon was only three or four kilometers, and the ships of the Ming Dynasty could not carry the recoil of this powerful Hongyi cannon, and even had to be hoisted to the platform to launch when firing, in comparison, we had to face a cannon with a range of only 600 meters. He paused slightly, pleased with the inquisitive gaze of the other person and continued. When there is rarely calm on the sea, the aiming of the Ming Dynasty artillery is simply a joke, at a distance of 600 meters they can't even hit the aircraft carrier, which is not to underestimate the Ming army, but the level of the world's navy at that time was very low, the British navy once required that it must be approached to 100 yards before it is allowed to fire, and 100 yards is less than 100 meters. This was the tragic distraction caused by the tragic range of the smoothbore artillery, so gang hopping was the mainstream in that era, first bombarding with solid shells, then approaching to sweep the opponent's deck with grapeshot or shotgun, and then letting the sailors jump over to capture the enemy ship. ”

Lin Shenhe smiled and nodded in agreement. "The range of artillery in that era was quite tragic, and we were able to cast and process rifled guns by ourselves after we passed, and the range was not a little higher than that of smoothbore guns, which was enough to slap them in the face outside the maximum range of the Hongyi cannon."

"Can we use bazookas at sea? I mean RPGs. Yuan Zhenli asked.

"Yes, but not recommended, because our ship has a lot of industrial equipment stored on board, and naturally there are more flammable materials, and the temperature of the tail flame generated by the rocket when it is launched is quite high, and if it is launched in a closed space, it is enough to burn the launcher. It is better not to use rockets on ships. ”

"But I often see Maozi shooting rockets on their boat!" Yuan Zhenli still has expectations for his rocket ship idea.

"You can prepare some rockets on board, but it's best not to use them unless you have to. If you set your boat on fire, you'll end up soaking in the seawater. Bu Zhongfu on the side smiled and replied.

"Oh, by the way, let's have a vote while we're all here." At this moment a dark, thin fellow stood up. "I'm Pan Dai from the Power Group. Now he is in charge of the electricity department. ”

Everyone did not speak, waiting for his next words.

"That's right, our power group has already made a list, and if we wait until the general meeting to understand the procurement list, it will be too late, so I will take advantage of everyone's presence to inform you of our list." Pan Dai said as he pulled out a stack of papers from his file bag.

Pan Dai is now in his thirties, wearing a pair of big glasses, his hair is unkempt and has not been carefully cared for, he is a temporary worker, he has worked in a company under a power group for eight years, has always belonged to the most tired work, the least salary, the credit can not be found, the black pot you carry the kind of back. This kind of work is easy to make people feel uncomfortable after doing it for a long time, so he simply chose to leave his job and become a leader in a new time and space where he has the ability and qualifications.

"I can only say that depending on the situation we are facing, hydropower is the best solution, and although wind and solar can provide electricity continuously, it is too affected by the weather and can only be used as a supplement. There are so many benefits of hydropower that I don't need to explain, for our group, the biggest advantage is that there is no need to refuel, and it can be used almost indefinitely after a one-time investment in construction. To know the German Siemens. The predecessor of Siemens, the predecessor of Siemens, was the Shilongba Hydropower Station in Yunnan Province, which began in 1910 and was completed in 1912, and is still operating normally. Pan Dai said, wiping the corners of his mouth and continuing. At present, there are small hydropower stations in all parts of China, and many small hydropower stations in rural areas are very simple, the installation difficulty is very low, and the project investment is not large. Aqueducts are used to generate electricity, and only five or six meters of water head are enough to operate. Such equipment in China has been very mature, small and micro units can be manufactured in a series of standards in China, the price is not high, and the maintenance is also very convenient. But at the same time, we also have to carry thermal motors, diesel generators are naturally the best, do not need to be erected, are not limited by the environment, put there to open to generate electricity, very convenient, can be used as the main means of power generation in the early days after landing. ”

Objections have been raised below. "Diesel always runs out, right? What to do with these diesel engines when they run out? Are they all back to the furnace? ”

Someone spoke. "There are many alternatives to diesel, and I remember peanut oil as well."

"I don't know if peanut oil is OK or not." Pan Dai turned his head to look at the person who was speaking, and continued. "Diesel engines can be converted into gas engines, and now many small rural power stations also use gas engines, so it should not be too difficult, and this should be considered by the industrial group."

"I think we can still make something like diesel in the future," Yang Minghuan raised his hand, "Please continue." ”

"It's not enough to bring diesel-gasoline generators and low-power hydroelectric generators, we need to bring some medium- and high-power hydroelectric units, and when we have enough capacity to build miraculous facilities such as barrage dams in the future, we will have enough strength to expand the capacity of the units. Wind turbines have a relatively small power and the electricity is not stable, but they are easy to set up and are sufficient as a backup power source for living quarters and bases. ”

"I remember that after the Fukushima earthquake, Germany removed all its domestic nuclear power plants and used wind and solar power to generate electricity, which is truly green and environmentally friendly." Someone in the industrial group in the audience raised questions.

"Germany's investment in green energy is very huge, but in fact Germany has only built wind power stations in a few major wind outlets, and although solar power plants are under large-scale construction, they are still not enough, and a large part of the electricity used by Germans is still provided by thermal power, but coal is used, unlike nuclear power, which has a destructive threat to the environment. However, I think we can send some of the energy team members to Germany to inspect the energy equipment. And electricity is not just a wire, which involves transmission and distribution, this part is very professional, I will not explain here, we will need a while to come up with the specific plan, and we also need to synthesize the terrain and landform that you have surveyed from there to make it. ”

Yang Minghuan nodded, "Electricity is very important, but there is a more important problem at the moment, the fuel problem, we are a world that burns oil, and it is difficult to live without fuel, so we will be more in urgent need of petroleum fuel." Yuan Fang, what do you think? ”

The one who stood up to speak was really a young man named Yuan Fang, in his thirties, one meter eight seven tall, like standing out from the crowd in a group of crossers, with a relatively slender figure and a slightly wooden expression.

He rubbed his nose, "I don't agree with Executive Committee Member Yang's opinion. "He has been working in the energy sector in the northwest of his country for many years, and he has made a lot of posts about energy during online discussions." Although petroleum products such as gasoline and diesel are necessary for our modern transportation and engineering equipment, these things not only have the possibility of volatilization, but also have the bottleneck of storage time. What we're going to talk about now is really just about the prime mover. ”

This problem obviously attracted the attention of everyone present, at this time it is not difficult to have a car, but as the National Development and Reform Commission as a state secret weapon several times a year to shoot down foreign aircraft, the price of gasoline and diesel has been soaring, from 5 to 7 more and more expensive, if there is no need to refuel, it will naturally attract everyone's attention.

"Whether it's a boat, a car or a motorcycle, they can all be driven by methods other than petroleum-based fuels, so the problem of petroleum products is not imminent." Yuan Fang straightened up and continued: "Basically, all the prime mover of petroleum fuels can be driven by modifying the gas generated by the gas generator. Of course, there will be some losses in power, but at the end of World War II, the Germans had experimentally installed gas generators on armored vehicles and tanks, and in the early days when China's petroleum products were not self-sufficient, many buses even used gas generators that burned wood and charcoal, so the power should not be too lost. The gas generator is not difficult to manufacture, simple and practical, and we can get through the window period of petroleum-based fuels. ”

"But what I want to say is that the most urgent thing to develop is the steam engine!" Yuan Fang turned his head to look at the industrial group. "How many years have the gasoline engine and diesel engine been around? What we want to build in the past is a world of the industrial revolution, so naturally we must not forget the greatest hero of the industrial revolution period - the steam engine! ”

"Steam engine?" Zhang Yuan was stunned, "This thing isn't sold outside, is it?" It's not easy to build your own, right? ”

"Is there any mistake?" Yuan Fang's temper has always been quite stunned, and when he saw Zhang Yuan's prevarication, he directly questioned loudly, "You are a mechanical group that claims to be able to build rockets and submarines!" What's not to do? The steam engine is a product of the 19th century! ”

Yuan Fang saw that the faces of the industrial team present were not good, and he also knew that he was talking too seriously, so he hurriedly said, "What's more, our prime mover can't always rely on reserve fuel to operate, right?" It's always going to run out, and we'll have to plan ahead, and if we run out of fuel and our steam engine hasn't been built yet, we might as well sit on the beach and wait to starve. ”

"Okay, although we haven't done this, but everyone knows the principle, there should be no big problem, and there should be ready-made design information on the Internet." Zhang Yuan paused as he spoke, "The steam engine itself is not too much of a problem, what is difficult to build is the boiler, the key is to see how far our materials can go, this depends on the level that the metallurgical group can provide." ”

"Isn't the metallurgical group also in the industrial group?" Someone below laughed.

"Of course, we have graduate students in metallurgy!" The people in the industrial group laughed, and a young boy sitting in the corner touched the back of his head in embarrassment.

"Then let the industrial team coordinate a plan first, Comrade Yuan Fang, you continue." Yang Minghuan glanced at the members of several groups next to him who were eager to try, and it is estimated that today's collective interrogation meeting will become a material procurement declaration meeting of various departments, but there is no way at the moment, it is impossible to discourage the enthusiasm of the comrades.

"I'm sorry, there's only so much to think about right now." Yuan Fang thought for a while and said.

"We can use alcohol instead of gasoline, and alcohol is more readily available than gasoline." "There is also biodiesel, a fatty acid methyl ester made by transesterification of vegetable oil with methanol, which is a clean biofuel, also known as recycled fuel," it was suggested. ”

"Isn't this gutter oil?" Someone asked curiously.

"Not to mention, this is gutter oil, Japan consumes 2 million tons of edible oil every year, and produces 400,000 tons of waste cooking oil, which provides the raw material for the production of biodiesel. The transesterification reaction is carried out by the enzymatic method, i.e., lipase, and the free fatty acids and water mixed in the reactant have no effect on the catalytic effect of the enzyme. After the reaction solution is allowed to stand, the fatty acid methyl ester can be separated from glycerol, so that a relatively pure diesel fuel can be obtained. However, there are several points worth noting and need to be studied and solved in the production of biodiesel by this method: 1. High transesterification rate cannot be achieved without the use of organic solvents, 2. When the methanol in the reaction system reaches a certain amount, the lipase is inactivated, 3. The reaction time is relatively long, and 4. In general, the price of enzymes is high. ”

"That's true." Sun Wenbin touched his chin and muttered to himself. "The price of the enzymes we bought in the factory was quite scary."

"Biodiesel is really good, I heard that Chongqing has a patented technology that can make the biodiesel produced meet the national GB252-2000 (No. 0) diesel standard, and a certain proportion of gasoline can be produced in the production, without glycerin, a by-product." Someone took a mobile phone and read it to the information found inside. "But the yield is not very good, I heard that Brazil is studying the use of bagasse as a raw material to ferment to produce high-quality diesel. One tonne of bagasse is said to be equivalent to a barrel of oil (31.5 gallons per barrel, 3.78 liters per gallon), and a Canadian laboratory has turned this into productivity, producing six barrels of biodiesel per day. ”

"Where are we going to find so much bagasse?" Someone asked.

"Didn't Mr. Huang recommend white sugar to us last time?" A person said loudly, "Since someone sells sugar, there must be a place for sugar production, as far as we know, the bagasse left over from sugar extraction is piled up, although it can be used to make wine, but the sugarcane bagasse in the sugar extraction is piled up like a mountain, and most of them have not had time to deal with it." ”

"I remember that there is a kerosene tree in Hainan, China, and the oil can flow out when the bark is cut, and the oil can be directly lit."

"That's just a lamp, not kerosene, and there are a lot of raw materials that can be used as biodiesel." Xiao Jing talked eloquently. "Camellia oleifera, stinky tung oil, Coptis chinensis...... Including the kerosene tree you mentioned, but the produced oil cannot be directly poured into the engine oil tank for direct use, and must be treated by catalytic enzymes and a series of modifications. In addition, no matter what kind of oil crop it is, one or two trees, even a small forest, are useless, and at least more than 100 acres can form an effective supply. ”

Someone in the agriculture group behind Sun Wenbin spoke. "I would like to point out in passing that these oil crops will not be able to produce oil until two or three years later, unless we can bring oil that can be uninterrupted for two or three years."

"I remember that at the end of World War II, didn't the Japanese dig pine roots and boil pine root oil? I've heard that you can also directly refine aviation gasoline. ”

"You just talk about it, the pine tar turpentine flotation oil extracted from the pine root oil is pitiful, and it is better to go directly to other oil substitutes or go directly to the oil with so much effort. Pine root oil should be kept as a medicinal herb. The Japanese have almost finished digging up the pine roots before boiling tens of thousands of barrels, and we don't know if there are pine trees in the past world. ”

At this time, a tall and thin man stood up, "My name is Liu Yeqiang, and when I used to work in Hainan, I designed, directed, and installed a set of oil shale refining equipment for a oil shale refinery. Oil shale is a relatively readily available product, and the products from the oil shale can be further refined into a variety of petroleum products, including gasoline and diesel. And the production is also considerable. ”

"As for treatment, it can be processed using a Maoming-style retort furnace with a capacity of 50 tonnes of ore per furnace per day, with an oil recovery rate of up to 60 percent, and if the oil shale has a high oil content, it can produce 10 to 15 tonnes per furnace per day, and it does not include by-products such as gasoline and ammonia."

Liu Yeqiang helped his glasses and continued: "This kind of furnace can be built without too many resources and manpower, a small factory with a daily processing capacity of 1,600 tons is 32 furnaces, and it is also necessary to build a gas heating furnace ventilator room, I have ready-made design drawings, the equipment is not difficult, such a plant can obtain more than 40 tons of crude oil in a day, not counting gasoline, ammonia, gas, phenol and other by-products, each of which is very useful." ”

"If the oil shale obtained is high, there is no need for a gas engine at all, and we can be self-sufficient in gasoline and diesel."

"Sixteen hundred tons!" Yuan Fang jumped up directly. "There are only more than 500 of us, and it's not enough to carry stones all of them! Not to mention the fact that it is not yet known where the oil shale is. ”

At this time, Liu Yeqiang showed the unfathomable smile of a senior intellectual behind his glasses. "It's a small scale for an oil shale refinery, okay. We have all trains and belts here. As he spoke, he took out a design drawing, "The design output on the map is not as much as a set of equipment in a certain oil shale refinery in reality, I have provided design drawings to several factories in Maoming, and their oil refining equipment is stronger than this, and the processing capacity of a furnace is 200 tons." ”

"This is basically a long-term plan, right?" Yuan Fang said helplessly, "The tonnage that needs to be occupied by such equipment is too large, and our current ship has not yet been decided, so it is not certain whether it can be loaded on the ship at that time." ”

This sentence deeply touched the people present, and now they have begun to gather a large number of crossing personnel and start the procurement of materials again. A large part of the hundreds of millions of lists issued by the medical team have been purchased, but the problem of ships has not been solved.

Last month, Yang Feng and Bu Zhongfu had already gone to other places to purchase ships, but this was a ship of tens of thousands of tons, and it was not a car.

"Okay," Zhang Yuan took over, "since we've caught up, I'll also talk about some of the things that our industrial team will bring." ”

Zhang Yuan then read out the list in his notebook, in fact, the things he brought were basically the equipment of his own factory, since he was about to roll over, the equipment of the factory had to be disposed of, if it was sold to second-hand dealers or disposed of as waste, it would be too wasteful. Therefore, as soon as the people in the industrial group discussed, it was better to simply pack them together and transport them to the warehouse of a certain port by the sea, store them first, and wait until the ship was in place and load them directly.

In addition to the equipment of the hardware factory, the industrial team also has some equipment specially used to manufacture standard parts such as bearings, screws, and gears. Usually, when the hardware factory needs these things, it is done by running the hardware market once, but after the crossing, don't expect to be able to visit the hardware market, so you have to prepare first, otherwise you have to be blind when you get there.

The two groups of people in the industrial group and the power group immediately began to grasp the list and began to discuss the tonnage required, after all, the carrying capacity of the ship is limited, if it exceeds 10,000 tons, it will definitely not be able to fit. For a while, the two sides began to quarrel over tonnage.

The people of the other groups also quietly mixed into the auditorium, giving advice to their own group to see how to bring the equipment more comprehensively, and the entire auditorium was gradually filled with people, and several fans overhead rotated weakly, so that the red-faced and red-eared crossers did not feel a trace of coolness at all.
