Haider walked into the restaurant, his eyes lit up when he saw the luxuriously decorated restaurant, but he didn't pay too much attention to it. He turned to look at Mag and said with a smile: "Boss Mai, thank you for taking the time to chat with me."
"Please sit down, I'm actually quite interested in these things." Mag smiled, put the water glass in his hand on the table aside, went into the kitchen, poured another glass of water, and placed it gently on Hai Hai who just sat down. In front of Del, he pulled out a chair and sat down in front of him.
When it comes to steam engines, it is not an exaggeration to claim that McGonagall knows everything. After all, for his graduation project that year, he independently completed an improved design of a two-stroke reciprocating piston internal combustion engine. Although this improvement proved to be difficult to implement in the final experiment, In theory, it can increase the thermal efficiency by three percentage points. With this thesis, he received a limited number of outstanding graduates.
This was the only thing he did seriously in the four years of college. In the process, he also studied steam engines, internal combustion engines, and steam turbines. He still remembered the structures and principles clearly, and even remembered a few Classic part models.
It is of course unrealistic to ask him to make these things with his own hands, but if he is asked to draw a few drawings and discuss the principles, there will naturally be no problem at all.
To put it simply, as long as he is given a powerful blacksmith who can make accessories that meet the standards, he can build a steam engine by himself and kick the world into the steam age.
However, McGonagall did not have much interest in doing this before. Whether it was Thomas Severi and Thomas Newcomen who invented the steam engine, or Watt who improved the steam engine, they only left a mark in the history of the development of the steam engine. His own name, and he is not very interested in leaving his name in history, but he is still quite curious about the mechanical level of this world.
"Thank you." Haider put the water glass aside, opened the cloth bag at hand and took out a few drawings from it and put them on the table. He looked at Mag and said seriously: "That's it, we have been studying it for these years. How to convert water vapor into kinetic energy and then use it in production and life to replace animal power and improve production efficiency. Now, we have successfully converted it into kinetic energy. Although the output is not yet stable, we already have It’s his idea that has stabilized, and the problem that needs to be solved now is how to transfer this energy to other objects to make this energy useful.”
"A very bold and interesting idea." Mag glanced at the rough drawings on the table, his eyes lit up, and he looked at Haider with a bit of respect. Unlike him, Haider did not have the shoulders of a giant. It can be stepped on, and the idea of using steam is already a genius. It is a spirit worthy of admiration to persist in doing this.
Mag still admired those scientists who devoted themselves to scientific research and invention. Their fantastic ideas and years or even lifetimes of research continued to push forward the progress of human society.
From the Industrial Revolution to the modern world, only two hundred years have passed. It can be said that a steam engine kicked off this great era and accelerated the development of human society.
The man in front of him was almost ready to do this.
The fine charcoal drawing is a bit rough, but the overall structure is arranged very clearly. It is a single-cylinder design. The steam pushes the piston in the cylinder, and then uses external water to cool it to form a low-pressure state in the cylinder and push the piston back, forming a reciprocating process. When moving, the connecting rod connecting the piston can obtain a certain amount of kinetic energy.
This steam engine model is very similar to the Newcomen steam engine. As Haider said, they have successfully turned steam into kinetic energy.
But there is still about a watt gap between using this kinetic energy in production and life.
However, to be able to achieve this level from scratch, Mag has great admiration for Haider and his team.
After all, in this world of swords and magic, people still worship knights who can control griffins and fly into the sky. Mechanics can be said to be a new and unpopular profession. If you tell people that one day ordinary people can fly into the sky, in If you can be faster than a leopard on land, you will probably be considered a lunatic, right?
"Thank you." Haider looked at Mag and said with some gratitude. He heard the recognition in Mag's eyes and words. It was different from the perfunctory expressions of ordinary people, or even the slightest ridicule. These things have changed over the past twenty years. He had been through a lot over the years.
From a head of thick black hair to now bald, no one knows what kind of pressure he and his team have been under for more than two decades.
Others were envious of their high salaries and subsidies, but a few of them knew that for this project, they, the core members, had put in almost all their savings. He and his wife are still living in the house allocated by the school more than 20 years ago. In the old house, I walked to class every day just because I really couldn't afford to pay for a driver and a horse. After one year, it was enough to make another model.
Except for his wife, who has lived in poverty with him all his life, not even his two children can understand these things, and they only go home once a year.
"You're welcome, but I'm curious why you want to study this?" Mag asked, looking at Haider with a smile. Mag Alex's memories were almost all about sword practice and fighting.
“After a hundred years of relatively peaceful development in Nolan Continent, commerce has developed greatly, and many trading houses have even appeared across the entire continent.
Manpower and animal power have begun to be unable to meet production needs. Although magic is very powerful, the high cost limits the use of magic by workshop owners. Of course, the application of magic is still very common in some expensive fine products. .
Therefore, we believe that the world urgently needs a low-cost, high-energy-efficiency power device. This idea has been recognized and supported by the city government. This is why this project that has not produced any effective results has been able to persist until now. reason. Haider replied seriously.
"Well, this is the best of times." Mag nodded. According to Haider, capitalism has developed to a certain extent on the Nolan continent, and people are beginning to urgently need something that can effectively improve production efficiency.
At this time, if a mature steam engine can emerge as the times require, it will definitely be promoted and applied in a short time. This should be the reason why the city government has been able to patiently support a money-burning project for more than 20 years.
"If this progress is followed, the first industrial steam engine will not be available in another twenty years." Mag looked at the drawing and thought with some pity in his heart. Suddenly, an idea flashed and his eyes lit up. , "How much can a complete steam engine blueprint cost?"
