Marin looked at the young men in the field with melancholy, and the girls bent down to harvest hard, feeling a little distressed. However, when he turned around, he saw Ada sitting by the field with his wife Lisa (Mona Lisa, please check the previous book for details) and painting leisurely, and then painted the oil paintings harvested by the farmer.
Marin was so happy - you old boy, you are leisurely. If you work hard, you don’t invent a machine to help. Are you not very smart? You also invented a machine lion, why didn’t you invent a harvester?
"Yes, I almost forgot Ada's mechanical talent!"
Then, Marin did run over and interrupted the leisure of painting between Leonardo da Vinci and Lisa and the flirting between husband and wife:
"Ada, come here, I'll find a job for you!"
"Don't do it! I have a serious business!" Leonardo da Vinci raised his beard and was very dissatisfied with the sweetness of Marin interrupting his husband and wife. Marin was usually easy-going, and if he had another noble, he would not dare to be so casual.
"If you don't do it, you have to do it, otherwise I'll let Kahn carry you to do it!" Marin said without looking back.
"It's really ungraceful..." Leonardo da Vinci just said, "How could he really not do it?" After all, Marin is his parents of food and clothing.
So, he was not ashamed to kiss Lisa by the field, said goodbye to his wife, and sprinkled a handful of dog food for the young man who was harvesting wheat in the field...
When Leonardo da Vinci panted and rushed to the manor where Marin lived temporarily, Marin teased:
"Ada, why are you just breathing like this after walking these few steps? You won't have kidney deficiency, right? It's not me that you should pay attention to moderation. You are not a young man like us, don't sing every night..."
"Don't talk nonsense, I'm very restrained, and the divine friendship is the main focus..." Leonardo da Vinci's face turned red and he was obviously lying.
Marin took out a quill and parchment paper, started painting, and asked Da Vinci to sit down and drink some boiled water first.
However, while drinking water, Leonardo da Vinci did not sit there, but stood curiously watching Marin's paintings...
When Marin drew for half a time, Leonardo da Vinci began to be a little interested. Because, he saw that it was a machine. Machinery was one of the things that Leonardo da Vinci was interested in. Otherwise, in 1515, he would not have created the "Leonardo da Vinci Machine Lion" to give to the King of Dharma. Moreover, Leonardo da Vinci's mechanical achievements were mostly achieved in his later years, mainly after the 16th century. Therefore, for the current period, Leonardo da Vinci had not yet entered the stage of the machine maniac. Because he probably also focused on music, painting, and dissecting corpses.
But in this life, under the guidance of Marin, Leonardo da Vinci devoted a lot of his energy to the mechanical aspects, studied clockwork and clockwork firers and other devices, and also created a sextant. Of course, as long as it was science, Leonardo da Vinci was interested. Therefore, he was soon interested in the steam engine drawings of Marin...
...
In fact, Marin had long planned to take the steam engine drawings to Da Vinci for research. However, the previous political environment did not allow it...
Why? Because Catholicism...
A steam engine is different from an invention like a musket because it does not require a horse, and God knows what kind of panic it will cause when it first appears...
If it was made early but it caused disgust of the Holy See, Marin himself and Leonardo da Vinci would probably be regarded as heresy by the Holy See...
If the Holy See is regarded as a heretic by the Holy See, although the status of a prince will not be tied up to a stake and burned to death, the princes in the German region who are unhappy will definitely use this as an excuse to line up to beat them up, destroy them, and then divide their property... Even the devout believers under their command may abandon themselves because of this...
Although there is also a possibility that the steam engine would not be rejected by the Holy See, Marin was unwilling to take this risk. Because this was the early 16th century, not the stage after Protestantism defeated Catholicism.
Where did Watt and the others build steam engines? Britain controlled by Protestantism. Only Protestantism will be more tolerant of the development of science. Conservative Catholics, especially when the Pope was still relatively authoritative, building steam engines was a very risky thing.
But now, Marin felt that the time was ripe...
Why? Because Marin's father-in-law will soon become the pope...
When Archbishop Rovere becomes the pope, who dares to say that Marin is a heretic? Damn, say that my son-in-law is a heretic. Come on, do you want to be extorted?
Therefore, under the premise that his father-in-law was about to become the pope, Marin finally let go of his courage and planned to let Da Vinci start developing a steam engine. Moreover, the development of a steam engine was not achieved overnight. By the time Ada created the practical steam engine, Archbishop Rovere was probably the pope. At that time, with the endorsement of the Pope's father-in-law, Marin could use the steam engine openly with confidence.
Of course, in order to reduce the difficulty, Marin did not draw a sketch of the twin-cylinder steam engine as soon as he came up, but a single-cylinder. After all, he had to do it step by step. Obviously, Ada had to do a single-cylinder and then get a double-cylinder.
Marin even knew the principle of the light Green Steam Engine. However, because the Green Steam Engine rotates, the cylinder cannot be larger, otherwise it will not be able to move. Therefore, the Green Steam Engine is only suitable for the power of a small boat, but not as the power of a large boat.
When Marin was working on a steam engine, he naturally had to equip the big ships, so Marin was destined to be a small Green steam engine. Marin didn't plan to do it first. Moreover, the shaft in the middle of the Green steam engine also had high material requirements. Because, not only should it be firm, it could tie the cylinders and prevent the cylinder from being thrown off. It also had to be elastic enough to ensure that the cylinders could rotate without restricting the movement of the cylinders.
Of course, Green Steam Engine was also able to do it. However, Green Steam Engine cannot be made large and practical in industrial and agricultural production. It is better to build a large single-cylinder steam engine first. Even if it cannot be used to drive ships for a while, it is good to use it to pump water. In fact, in the early 18th century, before Watt invented the Watt steam engine, someone invented a simple steam engine to pump water for mines.
If a steam engine was created to drive the water pump, it would be much easier for Marin to drain the water from the swamp. Unlike now, it could only be pumped slowly with a Dutch windmill.
Marin drew the pattern of the Watt steam engine for Leonardo da Vinci. Although it was a technology from the 18th century, it could be used even if it was taken out. The most important thing is that Marin remembers the most profoundly... Because Marin has seen such pictures since junior high school, he has seen them in high school, and has also seen them in college, and has seen them in dynamic pictures, which are the most profoundly impressive...
After drawing the Watt steam engine pattern to Da Vinci, Marin explained some key points, and then told Da Vinci to keep it confidential to prevent being discovered by the Holy See, and to be considered heretic...
Leonardo da Vinci didn't need to say much about this. After all, he was also a scheming person. Back then, he got a lot of corpses in the basement of his villa in Milan for dissection, which was also contrary to the ban on the Holy See. Therefore, he was very bold, but he was also very cautious and knew to avoid doing it.
