Chapter 286: Watt steam engine out

The four governor apprentices looked at Teacher Marin's explanation to them, and they were a little ignorant. They were frightened by Marin ’s endless array of conspiracies and tricks—does it take so many conspiracies and tricks to deal with an ignorant Indian native?

However, it sounds like if these tricks are implemented, they can really do more with less ...

And Wiltz listened to the fog. What Marlin said about nickel and chromium was something he had never heard of. However, Marin did not expect him to understand, but only told him that as long as it was smelted, nickel and chromium were silver-white metals. The most important thing is that nickel and chromium, mixed with iron, will become a new type of stainless steel-stainless steel.

What other red nickel sulfide, after high temperature roasting with air, will produce nickel oxide and irritating gas sulfur dioxide that can be reduced by a blast furnace, and Wiltz can hear it completely in the clouds.

In fact, Marin had no idea about Wiltz. Anyway, the smartest batch of teenagers, the elementary school knowledge is almost finished. Now, Marin and others have taken the time to write textbooks for junior high school, add the two disciplines of physics and chemistry, and select a group of civilian students with the best grades to teach them physical chemistry. By then, when these people graduate from junior high school, they can replace Wiltz, who lacks knowledge.

At this stage, Marin really has no expert in mining, so he can only let Wiltz stand up. Moreover, in Heidel's face, it is no big deal to give Wiltz a future. What's more, there is really no more suitable candidate than Wiltz. In the future, if Wiltz is free and willing to learn new physical chemistry knowledge, Marin will continue to reuse him. If he is unwilling to accept new knowledge, he can only make way for others. Anyway, a noble knight, and a manor, could almost kill him.

As for the new tender knight of Gorard, the team he led was more like a jungle expedition, and it was dangerous all the way. Fortunately, Marin let him bring enough mosquito repellent toilet water, but it can basically save his life. Moreover, Marin told him based on his experience-if you want to stay away from mosquitoes, the campsite is best to stay away from the river. Because most mosquitoes hide in the water and grass by the river to avoid the heat during the day, and come out to **** blood at night. Staying away from the river can indeed reduce mosquitoes.

In addition, the dense tropical rain forest is also a hiding place for mosquitoes. Therefore, Marin planned to buy a group of black slaves from the Portuguese colonists. In order to prevent the spread of black slaves in the future, Marin decided to only buy male black slaves and not female black slaves, so as not to give birth to a bunch of small black slaves in the future. As for whether the black slave would invade the Indian woman to give birth to a mixed race? Don't worry about that. Because black slaves are locked up to sleep at night. Want to play? You can do it by yourself, or by hand ...

Anyway, Marin will never make the mistake of being old and beautiful in history-in order to save money for buying black slaves, let the black slaves reproduce themselves ...

In this way, a few hundred years later, there will not be a group of black uncles in America. Although, there may be no good-looking nba, but at least the security will be much better.

Marin is not a racist, but in the face of a lazy, non-learning, and likes to race against the law and discipline, Marin can not like it.

In his previous life, Marin was in China, and he always saw a group of so-called bricks called beasts, criticizing what exam-oriented education. However, if there is no strong pressure for exam-oriented education, and only "quality education" of "playing together" is left, then the Huaxia people may fall into old age, only knowing that they are idle and not learning.

Marin even wondered whether the so-called "quality education" of "let children play" was a question of whether the Yankees studied abroad in the United States through some kind of trust relationship, and entered a wrong idea with Huaxia. nice.

You know, Huaxia has always lacked this kind of relationship-based and money-based study abroad. For example, someone named Hehe, went to study in the United States. As a result, what did she learn? Sexology ... Special experts ... Special code, actually mixed into the Academy of Social Sciences and the CPPCC ...

The question is, what kind of birdies did this product do? Actually, by relying on the identity of the CPPCC who did n’t know what relationship was used, it demanded the legalization of the foundation, and it also abolished the crime of “gathering the crowd to chaos”. This clearly encourages everyone to mess up ...

This is the face of the international students who are related to the special code. The things that have been learned are not the same. They are blown away in the country, but they are still safe ...

The kind of "quality education is to play" is estimated to be the theory put forward by this kind of related households "remaining aesthetics", which specifically harms China ...

Uh ... off topic ... not to mention the pervert ...

In short, as long as the black slaves are chained, they do n’t worry about messing with them. As long as the little black people are not brought out, there will be no chaos in the future. Although it is said that the black farming cannot catch up with the Chinese and Asan, but they still have a lot of strength. This kind of strength can be used to cut down trees.

What Marin needed was for the black people to cut down all the trees on the road from Cologne to Panama City so that they could use it to repair the road. Once the road is repaired, you can use Panama City as a base to sail and sail directly to Daming through the convenient Pacific route. Then, the huge profits of silk, porcelain and other trades will roll in ...

...

The reason why Marin has to take this route is because this route is best suited to rely on wind. In the days when steam engines were not used for steamships, sailing was purely driven by wind. If there is no wind or headwind, the sailing boat will be difficult to move forward, or even stop, and follow the waves.

Thinking of the steam engine, Marin decided to go to Watt's Steam Engine Research Institute to inspect the development progress ...

In fact, after visiting Da Vinci ’s steam engine last time, Marin found that it was particularly like the original Newcomen steam engine, so he told Watt ’s principle of the “sun and planetary gear transmission system” and the principle of the condensation cycle system After Da Vinci, Da Vinci set about to rebuild the previous Newcomen steam engine.

After several months of improvement, Da Vinci has already developed the "sun and planetary gear transmission system" and "condensation circulation system" at this time ~ www.wuxiaspot.com ~ Moreover, the test has been completed and the effect is good.

In fact, these two systems are not difficult. After all, Marin has explained all the principles and ca n’t get it out. It is too insulting to Da Vinci ’s IQ. People are one of the smartest people of this era. If Marin is not a traversal, it is estimated that they are not qualified to bring shoes to others.

Next, design the governor that Marin didn't understand. Later, Leonardo discovered that if the cone swings too fast, the iron ball will generate a force outward, and then push the cone upward.

Using this force, a connecting rod can be designed to control the steam input valve, so that the steam output is reduced and the speed of the steam engine is reduced. However, if the speed of the steam engine is too slow, the cone pendulum will fall, and then, because the connecting rod controls the valve, the steam in the pipeline will increase the output and increase the speed.

After realizing this, Da Vinci quickly improved the steam engine and added a cone pendulum. Through the transmission system, the cone pendulum is connected to the rotating part of the steam engine output, and then there will be a connecting rod at the top to connect a valve in the steam output pipe. If the output speed of the steam engine is too fast, then the cone swings upward, driving the valve to close, reducing the steam output speed, and reducing the output rotation speed. Conversely, the cone swings down, the valve opens, and the steam engine output speed increases ...

When Marin passed by, it was discovered that Da Vinci was testing the function of this flyball governor and was successful. After discovering that the governor finally tested successfully, Leonardo embraced the people around him excitedly. After the hug, Da Vinci was surprised to find out-it was Marin who came ...
