Chapter 61： Ada, get a steam engine!

Marin looked sadly at the young guys and elder girls in the field bending over to harvest hard, and felt a little distressed. However, as soon as he turned his head, he saw Ada sitting with his wife Lisa (Mona Lisa, the details can be found in the previous book) and leisurely painting at the edge of the field.

Marin qi is happy-you are an old boy, but leisurely. People work hard, you do n’t invent a machine to help, do n’t you have a big brain? I also invented the machine lion, so why not invent a harvester ...

"Yeah, I almost forgot Ada's mechanical talent!"

Then, Marin really ran over, interrupting the leisurely painting between Da Vinci and Lisa and the flirting between the couple:

"Ada, come here, I will find a job for you!"

"Don't do it! The husband has something to do!" Da Vinci's beard tilted, and was very dissatisfied with the sweetness Marlin interrupted his husband and wife. It is also that Marin is usually easy-going and replaced with another nobleman, and he dare not be so casual.

"If you don't do it, you have to do it, or I will let Kahn carry you to do it!" Marin said without looking back.

"It's really unpretentious ..." Da Vinci talked about it, how could it not be done. After all, Marin is his food and clothing parents.

So, he was old and not shy. He kissed Lisa at the edge of the field, said goodbye to his wife, and gave the young man who harvested wheat in the field.

Waiting for Da Vinci to rush to the manor where Marin temporarily lives, Marin teased:

"Ada, how about taking these few steps? You won't lose your kidneys? Isn't it that I said you, be careful of temperance? You're not a young man like us, don't sing at night ..."

"Don't talk nonsense, the old man is very restrained, and the devotion is the main ..." Da Vinci's old face blushed, and he obviously lied.

Marin took out the quill pen and parchment paper, and began to paint, let Da Vinci sit down and drink some water.

However, Da Vinci drank water, but did not sit there, but stood curiously to see Marin's drawing ...

When Marin drew a little and a half, Da Vinci became a little interested. Because, he saw that it was a machine. And machinery is one of the things that Leonardo is interested in. Otherwise, in 1515, he will not create the "Da Vinci Machine Lion" to give to the King. Moreover, most of Da Vinci's mechanical achievements were made in his later years, mainly after the 16th century. Therefore, for the entire period of time, Da Vinci has not yet entered the stage of machine madman. Because, he probably also focused on music, painting and autopsy.

But in this life, under the guidance of Marin, Da Vinci put a lot of energy into the mechanical aspect, studied clockwork and clockwork firearms and other devices, and also made a sextant. Of course, as long as it is science, Da Vinci is interested. So, he was very interested in the steam engine drawing painted by Marin ...

……

In fact, Marin had already planned to give the drawings of the steam engine to Leonardo. However, the previous political environment did not allow ...

Why? Because of Catholicism ...

The steam engine is different from the invention of the musket, because it does not require horses, and God knows what kind of panic it will cause when it first appears ...

If it was made early, but it aroused the Holy See, Marin himself, and Da Vinci, are probably very likely to be regarded as heretics by the Holy See ...

If it is regarded as heresy by the Holy See, because of the princehood, although it will not be tied to the pillar of fire and burned to death, those princes in the German area who look at themselves unhappy will definitely use this as an excuse to line up to beat themselves and destroy themselves And then divide up his own property ... even, the pious soldiers under his command may abandon himself for this reason ...

Although there is a possibility that the steam engine will not be rejected by the Holy See, Marin is not willing to take this risk. Because this is the early 16th century, not the stage after Protestantism defeated Catholicism.

Where are they doing steam engines? Protestant Britain. Only Protestantism will be more tolerant of the development of science. The conservative Catholic Church, especially during the period when the Pope was more authoritative, was a risky business to engage in steam engines.

But now, Marin feels the time is ripe ...

Why? Because Marin's father-in-law will soon become the pope ...

When Archbishop Rovere became Pope, who dares to say that Marin is heresy? What's special, saying that my son-in-law is heresy, come and come, do you want to be punished?

Therefore, under the premise that his father-in-law will soon become the pope, Marin finally let go of his courage and intends to let Da Vinci start to develop a steam engine. Moreover, the development of steam engines is not done overnight. By the time Ada brought out the practical steam engine, it was estimated that Archbishop Rovere had become the pope. At that time, with the endorsement of the pope's father-in-law, Marin can safely use the steam engine publicly.

Of course, in order to reduce the difficulty, Marin did not draw a sketch of the double-cylinder steam engine as soon as he came up, but a single-cylinder. After all, it is necessary to go step by step. Apparently, Ada has done a good job with a single cylinder, and then went to get a double cylinder.

Even Marin knew the principle of the portable Green steam engine. However, because the Green steam engine is rotated by the swing cylinder, the cylinder cannot be enlarged, otherwise it will not swing. Therefore, the Green steam engine is only suitable for the power of small boats, not for the power of large ships.

Marin's steam engine naturally needs to be equipped for large ships, so it is destined to be a small Green steam engine, and Marin does not intend to do it first. Moreover, the middle shaft of the Green steam engine has very high requirements for materials. Because he must not only be strong, but also be able to tie the cylinder and not let it escape. Moreover, there must be enough elasticity to ensure that the cylinder can be rotated without restricting the movement of the cylinder ~ www.novelhall.com ~ Of course, the Green Steam Engine wanted to do it, and it was also done. However, because the Green steam engine cannot be enlarged, it is not practical in industrial and agricultural production. It's better to build a large single-cylinder steam engine first, even if it can't be used to drive the ship at once, it is also good to use it to pump water. In fact, in the early 18th century, before Watt invented the Vata steam engine, someone invented a simple steam engine to pump water into the mine.

If a steam engine is used to drive the water pump, then Marin wants to drain the water in the swamp, it is much easier. Unlike now, you can only use the Dutch windmill to pump slowly.

Marin gave Leonardo a natural drawing of a Watt steam engine. Although it is an 18th-century technology, it can be used after it is taken out. The most important thing is that the design of the Watt steam engine, Marin has the deepest memory ... because, since Marin junior high school, I have seen such a picture, I have seen it in high school, and I have also seen the dynamic picture in the university, and I am most impressed by nature. ...

After drawing the drawing of the Watt steam engine to Da Vinci, Marin explained some points, and then told Da Vinci to pay attention to confidentiality to prevent it from being discovered by the Holy See and regarded as heresy ...

For this, Da Vinci doesn't need Malindo to say that, after all, he is also a man of scheming. At that time, he had obtained many autopsies in the basement of his villa in Milan, which also violated the Holy See prohibition. Therefore, he is very bold, but also very cautious, knowing to avoid doing.

Considering that this matter should not be made public, Da Vinci is like Marin asking for a group of young craftsmen of serfhood to serve as assistants, not the old craftsmen invited from Italy. Because, serf craftsmen are not easy to leak. After all, they cannot leave without Marlin's permission. Unlike those experienced craftsmen recruited in Italy, they are in the capacity of guest secretary, they are more free, and it is easier to leak ...
