Increasing the speed of the ship is a big technical problem, and it does not mean that increasing the output power will increase the speed significantly. There are two formulas in the shipbuilding industry www.biquge.info which are used to summarize the relationship between the power, tonnage and speed of the ship. Power is proportional to the power of the tonnage to the power of the third of the tonnage, and power is proportional to the power to the third of the speed.

This formula may not be easy to understand, but a few examples will make it clearer.

For example, a 50,000-ton ship has a main engine of 10,000 horsepower, and it can travel at a speed of 12 nautical miles when fully loaded. And a high-speed ship with a displacement of only 300 tons needs more than 10,000 horsepower to run more than 30 knots.

Another example is the Arleigh Burke-class destroyer, with a full load displacement of less than 10,000 tons, a main engine of more than 100,000 horsepower, and a speed of 31 knots. The Nimitz-class aircraft carrier has a displacement of more than 100,000 tons, a power system of 260,000 horsepower, and a speed of 30 knots.

It can be seen that the gap between power and tonnage is not large, but the relationship between power and speed is very large. If you use the same power to propel a ship with a displacement of twice as much, the speed will not drop too much, but if you want to double the speed, the power will have to be increased by ten or dozens of times. There has been no good solution to this problem until later generations, and I am not an expert in shipbuilding, so of course there will be no way.

"Okay, if you can see it alive, I guess I won't die......" Wen Xiaoqi was slightly moved, mainly because Hong Tao's reputation in this regard is good, whatever he says can be done, it can be done 100%.

"That's not necessarily, if you stay up for days without sleeping, or secretly go to death, you won't necessarily be able to consume more energy than me. Look at our muscles, and then look at your body, and say that I am your brother, and some people believe me. Don't sit on the slipway all day long, eat, sleep, exercise, or at least you have to wait until I'm dead before kicking my legs. You said that in your life, you can't beat me, you can't scold me, you don't marry as many daughters-in-law as me, you don't have as many children as me, you don't eat as much, you don't drink as much as I do, you can't even kill me, you say you die earlier than me, do you lose money in this life? In addition to the problem of the boat, Hong Tao just took advantage of the topic to talk about Wen Xiaoqi's physical problems. It's not an exaggeration at all, if someone who doesn't know Wen Xiaoqi and Hong Tao meet for the first time, it is really possible to think that Wen Xiaoqi is several years older than Hong Tao, which has a lot to do with daily maintenance and energy.

"Good people don't live long, bad people live for a thousand years...... Pressure! Full! "Wen Xiaoqi made Hong Tao so crowded that he couldn't feel the meaning of life, he had lived for decades, and he was not as good as a person. But what Hong Tao said is really right, in fact, there is at least one thing to say, and Wen Xiaoqi, who is playing tricks, is not an opponent. So Wen Xiaoqi sprinkled all his grief and anger on the copper pipe, and this loud shout was like thunder.

The weather in Mexico is characterized by a pleasant year-round situation in the highlands, and a humidity but not high temperature in the coastal areas, both in the rainy and dry seasons. In the southern inland plains, the rainy season is a bit uncomfortable, not only the humidity is high, but the temperature is also relatively high, like a big steamer.

In addition to verifying the performance of the steam engine, the industrial ship also had a task, which was to inspect the canal construction site along the way. It has been almost two years since the canal started, and Hong Tao has only come back once halfway, not because he doesn't want to come, but because everything has come together, and he really doesn't have time.

Entering this canal after more than a year is really different from before. From the beginning of the estuary, the originally lush forests on both sides of the river bank have been artificially trimmed, which not only maintains the role of the trees in protecting the soil on the bank, but also prevents them from growing wildly and obstructing the smooth flow of the river. Every 10 kilometers or so, there is a wooden tower and a small pier, which is a canal defense system set up along the way of Swan, passing through the most primitive wolf smoke during the day and setting off fireworks at night to communicate information with each other.

When the Industrialist was about 150 kilometers down the river with black smoke, a huge village suddenly appeared on the north bank of the river, more than five times larger than the Indian village he had seen when Hong Tao first arrived in the Americas. However, the atmosphere here is diametrically opposed to the natural and peaceful Indian village, in addition to the dense watchtowers, you can see the Union army with loaded guns everywhere, to be precise, it is a large military camp and a large warehouse. And this place is the final point of the sailing ship against the current, which is the place where the big rock was determined. Now it's called Stone Harbor, except that the big stone was blown away during the construction of the harbor.

Located at the junction of mountains and plains, this port is the headquarters of the entire canal project, and it is also the assembly and transfer station for most of the personnel, materials and food, and controls the communication between the canal site and the outside world. As Swann said, as long as the stone harbor is controlled, the slaves on the construction site have nowhere to escape. Unless they are willing to brave the overwhelming barrage of poisonous insects, mosquitoes, flies, and wild beasts into the tropical jungle to die, they will have to rely on supplies from Stone Harbor to survive. Every day, a string of small boats relied on the power of oars to carry the day's food and tools upstream to the construction site, and then to transport the sick and wounded from the construction site back to Stone Harbor.

"What does the South Bank do? There is vacant land in the north, so why do you have to go to the south bank to do construction? After listening to Joseph's brief introduction to the situation of Stone Harbor, Hong Tao found a layout that was not very reasonable. On the south bank of the river, there is a large area of woods that has been burned by fire, but has not yet been cut down.

"It's a forbidden place for the gods...... "When Joseph heard Hong Tao's question, his face, which had been expressionless for three hundred and sixty-five days a year, actually showed a trace of hesitation.

"Talk to me!" Hong Tao was a little impatient, what is the forbidden land of God? What's going on with this Divine Sect, do you still use yourself to explain to him, and now there is no one around, why bother talking so mysteriously.

"It's a place where bodies are burned...... The climate here is not suitable for burial, and the wounded and sick on the construction site are brought to the south bank for cremation if there is no need for treatment. Joseph held the glittering golden book to his chest, as if it would calm him down.

“…… How many people have been burned so far? This is indeed a very heavy topic, just looking at the burned area of the forest, Hong Tao can roughly feel that the number of deaths will definitely not be small.

"Three thousand seven hundred and ninety-two...... Another 1,000 and 5 people were cremated on the construction site without finding their bodies or no longer fit to be transported back for disposal. Then Joseph opened the book in his hand, and after looking at it, he gave a very accurate number. It wasn't a scripture at all, it was his ledger.

"How many slaves are there here?" In the past two years, nearly 5,000 people have died, and it can be seen that these dozens of kilometers of rivers are really not very easy to dig, and an average of about 100 people will die per kilometer, and God knows how many more people will die until the completion is completed.

"Twenty-seven thousand five hundred and eleven, while maintaining five thousand inhabitants of the Kingdom of God, they are rotated, and each group works for two months. The death toll just now does not include them, and as of today, a total of 175 residents of the Kingdom of God have entered the Kingdom of God. "Joseph has reached the highest level of deception, and as he speaks, he has returned to the state of high priest.

"It's almost a fifth of the casualties, isn't it too high?" Hong Tao was a little creepy when he heard it, on average, one out of five people died here, and the forest on the south bank must be closed in the future, it was too terrifying.

“…… My lord, I'm talking about the number of people who were cremated, not the disabled. If you count the disabled, add another two thousand two hundred and seven people. I sent most of them to Saba City and sent them to work in the factory. There are also hundreds of people who are not too disabled to go to the construction site to continue working, so they stay here to help in the docks and warehouses. Joseph was honest and immediately corrected Hong Tao's misunderstanding.

"Have you ever been to a construction site? Were there any cases of deliberate abuse of slaves and deliberate killing of slaves? Hong Tao instinctively felt that there were too many dead and wounded, so he had another conjecture.

"I haven't seen it, but there were fights among the slaves from time to time, mostly over extra rations of food and medicine. Normally, when this happens, General Swann will pull the wounded person out alone and put him in the most dangerous section, which is actually no different from execution. Joseph shook his head and denied Hong Tao's speculation.

"That's good, don't abuse them too much, when the canal is repaired, these people will still be our people, don't make too deep hatred. By the way, what about Lao Luo and my son-in-law? Joseph said no, the credibility was very high, he didn't even want his kingdom for free, there was no reason to lie to himself on these small issues. And this kind of thing can't be hidden, you can figure it out with a little turn and asking.

"They went to the westernmost site to inspect the site, and three days ago they went with the ship carrying the explosives. That's the last mountain beam, and once it's connected, the canal is basically in shape, and the rest of the work will be much easier. Your son-in-law thinks the slaves' blasting techniques are too dangerous, and he says he'll go to the construction site to see if he can optimize the process with the most dead people. Joseph finally smiled a little, wondering if he was celebrating the completion of the project, or if he was celebrating the end of the hard work.

"He's a fart! People who have never even seen nitrocellulose dare to come here to open their teeth. Luo Youde, who is a father, is also old and confused. Get me a few people, I'll have to go up and have a look. He doesn't want a son, I can't let my daughter be widowed so early, no one is worried! As soon as he heard that Luo Meimei went to the construction site to guide the work of using explosives to open the mountain, Hong Tao immediately became anxious, who didn't know that this work was dangerous? Even Bush, who has been at the mercy of these things all year round, will naturally not have any good way, which is tantamount to losing and sending him to death.
