Chapter 255: This is the best time (thanks to the 100,000 rewards of Ripley's 233 children's shoes!)

Haider walked into the restaurant and looked at the luxuriously decorated restaurant, but didn't pay much attention to it. Turned and looked at McGonagall and smiled: "Mc. Boss, thank you for taking the time to talk to me."
"You please sit down. Actually, I am very interested in these things." Maggie smiled, put the water in the handle on the table next to him, went into the kitchen and poured a glass of water, and placed it in the sea just sitting down. In front of Del, pull the chair and sit down in front of him.
When it comes to steam engines, McGonagall can't be overwhelmed. After all, he graduated from the design of the two-stroke reciprocating piston internal combustion engine. Although this improvement proved to be difficult to use in the final experiment, In theory, it can improve the thermal efficiency of three percentage points. With this completed paper, he has won outstanding graduates with limited quota.
This is also the only thing he has done seriously in the university for four years. In the process, he also studied the steam engine, internal combustion engine and steam turbine by the way. The structure and principle are still clearly remembered, and even remember a few. Classic part models.
It is unrealistic to let him personally make these things, but if he is allowed to draw a few drawings and discuss the principles, naturally there is no problem at all.
To put it simply, if you give him a powerful blacksmith and can make accessories that meet the standards, he can make a steam engine alone and put the world into the steam era.
However, McGonagall did not have much interest in doing this before, whether it was the invention of the steam engine Thomas Severly and Thomas Newcomen, or the improvement of the steam engine w, they only left in the history of steam engine development. His own name, and he is not very interested in the history of the name, but he is still very curious about the mechanical level of the world.

Thank you.
Haider put the cup aside, and opened the cloth bag on the side of the hand and pulled out a few drawings from the inside to the table. He looked at Meg’s expression and said:
This is the case. We have been studying 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 him into kinetic energy, although the output is not stable, but we already have It is his idea of ​​stabilizing. The problem that needs to be solved now is how to transfer this energy to other objects, making this energy useful."
"Breaking and interesting thoughts." McGonagall glanced at the rough drawing on the table, his eyes lit, watching Haider's eyes with a little respect. Unlike him, Haider did not have the shoulders of giants. I can step on it, I can think of the idea of ​​using steam is already very genius, and insisting on doing this is a kind of admirable spirit.
For those scientists who are immersed in scientific research and invention, McGonagall is still very admired. Their whimsy and years of study, and even their life, continue to push forward the human society.
From the industrial revolution to the modernized world, but in just two hundred years, it can be said that a steam engine has opened the prelude of this great era and accelerated the development of human society.
The man in front of him has almost done this.
The drawings of the fine charcoal painting are somewhat rough, but the overall structure is very clear. The single cylinder design, the steam pushes the piston in the cylinder, and then the external pressure is used to cool the cylinder to push the piston back into the low pressure state, forming a reciprocating Movement, connecting the connecting rod of the piston can get a certain 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.
However, the use of this kinetic energy in production and life is still about a watt distance.
But from scratch, to be able to do this, McGonagall has been very admired by Haider and his team.
After all, in this world of swords and magic, people are still admiring the knights who can ride the gryphons. The machinery can be said to be a new and unpopular profession. If you tell people that one day ordinary people can fly to the sky as well. The speed on land can be faster than the leopard, probably only considered a madman?
"Thank you." Haider looked at McGonagall with some gratitude. He heard the approval in Meg's eyes and words. It was different from the perfunctory expression of the average person, and even there was no taunting. These things are more than 20 He has experienced a lot in the years.
From a thick black hair to a bald look, no one knows how much pressure he and his team have been subjected to over the past two decades.
Others envy their high wages and subsidies, but several people know that for this project, their core members have posted almost all their savings. He and his wife are still living in school more than 20 years ago. In the old house, walking to class every day is just because I really can't bear to ask a driver and raise a horse's money. It is enough to make a model in one year.
These things, in addition to following his wife who has lived a poor life for a lifetime, even the two children can not understand, and even only return home once a year.
"You're welcome, but I'm curious why you want to study this?" McGonagall smiled and looked at Haider. The memory of McGonagall was almost all about practicing swords and fighting.
After the relatively peaceful development of the Nolan continent, the business has been greatly developed, and there have even been many businesses across the continent.
Manpower and animal power have begun to meet some production needs. Although magic is a very powerful existence, the high cost limits the use of magic by the workshop owner. Of course, in some expensive and elaborate products, the application of magic is still very common. .
Therefore, we believe that the world urgently needs a low-cost, energy-efficient power plant. This idea has been recognized and supported by the city government, and this project, which has not produced any effective results, has been able to adhere to the present. the reason. Haider answered seriously.
"Well, this is the best time." McGonagall 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 the mature steam engine can be born, it can definitely be promoted and applied in a short time. This should be the reason why the city government can patiently support a burning project for more than 20 years.
"If you follow this progress, in the next 20 years, the first industrial steam engine will not be available." McGonagall looked at the drawing, and there was some pity in his heart. Suddenly, the eye flashed and his eyes lit up. "How much can a full steam engine drawing sell?"
