Chapter 463: Zhu Biao, The Business Sage And The Science Sage Who Attempt To Span Several Energy Era
After Yan Changqing cleaned up the debris on the podium, he looked at Zhu Yuanzhang, who was still in a state of shock, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, and said in a gentle tone:
"It is not difficult to ignite paper. If you make tens of thousands of concave glass mirrors that can focus light and combine them together, you can focus the sunlight to a single point."
"Then make thousands of mirrors that can refract sunlight and refract it all onto that huge concave mirror."
"Then the center point focused by that huge concave mirror is hot enough to melt steel!!!"
"There is also a magnifying glass with better light-focusing effect, but it is more troublesome to make. The craftsmen are still researching and making it, so I won't talk about it.
"Anyway, the function is the same as the magnifying glass you hold, except that the focusing effect is relatively better."
In Yan Changqing's previous life, someone had done a similar experiment. The name of the product of that experiment, or the name of the huge light-concentrating concave mirror, was called "Odie's Solar Furnace"
And the temperature that Odie's solar furnace finally focused on was as high as more than 3,600 degrees!!!
The melting point of iron is only 1,538 degrees, and the boiling point is only 2,750 degrees.
The high temperature of more than 3,600 degrees is enough to melt iron into boiling molten iron.
As for the magnifying glass he was talking about that has a better focusing effect, he actually refers to a Fresnel lens, also known as a threaded lens. Most of them are thin sheets made of polyolefin materials.
However, there are also lenses made of glass. One side of the lens is smooth, and the other side is inscribed with concentric circles from small to large. Its texture is designed based on the interference and interference of light, as well as relative sensitivity and reception angle requirements.
This kind of Fresnel lens has a much better and stronger light focusing effect than an ordinary magnifying glass.
However, the production process is obviously much more troublesome than an ordinary magnifying glass.
After all, there is no injection molding technology in this era. We can only rely on the glass craftsmen to research and try to make them based on what he said.
But obviously, this cannot be done in three or two days, so today Yan Changqing just took out the magnifying glass he had just made in the past few days to give an example.
"Melting steel?!!"
Hearing Yan Changqing's description, Zhu Yuanzhang couldn't help but exclaimed.
There is a huge difference between igniting paper and melting steel!!!
After all, he could still reluctantly understand and accept the paper ignition. In the past, when the weather was too hot in summer, if it was too dry, the spontaneous combustion of dead grass and dead wood had happened.
But no matter how hot the summer is, it will never be hot enough to melt steel.
If it really comes to that point, all the people will have died before the steel is melted.
"If this is the case, then wouldn't we be able to use it to replace the furnaces for steel smelting in the future?!""!"
"In the future, there will no longer be a need to build blast furnaces and consume fuel to smelt steel!!!"
Prince Zhu Biao's eyes widened and he spoke with great interest.
There was the previous example of igniting paper, and the doctor had no doubts about what Chang Qing said about melting steel.
And if steel can be melted, wouldn’t it be possible to eliminate the need for furnace fires for steel smelting in the future?!!
In this way, the cost of steel smelting can be greatly reduced.
As for what Yan Changqing said about the need for more than 10,000 glazed mirrors, since I learned that those glazed mirrors are made of sand.
Zhu Biao, or Zhu Yuanzhang and his son, basically regarded Liuli as a business without capital.
Not to mention more than 10,000 glazed mirrors, even 100,000 mirrors or 1 million mirrors are no different from spending money.
Yan Changqing, who was on the podium, looked at Prince Zhu Biao in surprise and couldn't help but complain:
[Good guy, we haven’t even entered the steam energy era yet, but we are already thinking about entering the solar energy era!!!]
[This is because I want to transcend several energy eras in one step and directly stand shoulder to shoulder with future generations!!!]
After secretly complaining a few words, Yan Changqing looked at Prince Zhu Biao, shook his head and said:
"Although steel can be melted by focusing a large amount of solar energy, at present, solar energy does not have the feasibility of promoting and replacing Tsumito blast furnace smelting["
"First, because compared to ordinary blast furnace smelting, smelting by focusing on solar energy has a fatal drawback, that is, it still needs to depend on the weather!"
"In other words, it doesn't have stability."
“Once it encounters non-sunny weather such as multiple, cloudy, rainy days, etc., the effect of the sunlight it can focus will either be greatly weakened or completely eliminated.
"This is obviously unacceptable for normal steel smelting.
"The second reason is because the sunlight focused through the concave glass mirror is concentrated on one point!"
"Just like the spot of light that His Majesty and Your Highnesses just refracted and focused through the magnifying glass, the area is very small!!"
"Only at the point where it is focused in the center will it have such a high temperature, and the temperature will drop rapidly around it!!!"
"In other words, even if it is used to smelt steel, it can only carry out steel smelting operations in the central focus area, and cannot carry out large-scale steel smelting operations around it!!!"
"And if we only rely on the central focus area to carry out steel smelting operations, the efficiency of steel smelting will undoubtedly be very slow!!!"
“So if you want to focus on solar energy for steel smelting, it’s not of much use at the moment.
"However, we can build such a wonder, and it will be built in the Academy of Sciences of the People."
"After it is completed, Your Majesty and Your Highnesses can come and take a look."
While Yan Changqing was talking, he was already thinking about where to build such an "Oudi's Solar Furnace" in the Academy of Sciences.
[When the time comes, let’s change the name. Should it be called the Golden Crow Solar Furnace or the Akamaru Solar Furnace?!!]
[It seems that the Xihe Solar Furnace sounds pretty good, and the Yangbi Solar Furnace also seems to work...][
Prince Zhu Biao, who heard Yan Changqing's answer below, looked slightly disappointed, but immediately returned to normal.
After all, he just said it casually out of interest. It's not like he really has high expectations for steel smelting by focusing sunlight.
"Academy of Science for All People?!!"
"When did the Ming Dynasty gain another Academy of Science for the People?!!"
Chu King Zhu Zhen muttered with some doubts.
If he remembers correctly, isn’t there currently only Wanmin Agricultural College and Wanmin Medical College in Ming Dynasty?!!
On the podium, Yan Changqing looked at Chu King Zhu Zhen and replied:
"."Didn't Your Majesty sell me two Saint's positions and two Saint's colleges for 10 billion before?!!"
"Of those two Saints, one will be the Saint of Business and the other will be the Saint of Science, and their respective colleges are called [Wanmin Business School] and [Wanmin Academy of Science] respectively!!!"
When Zhu Yuanzhang sold him the two Saint positions and Saint College, he had already thought about what type of Saint the two Saints were and what their respective colleges were.
Among them, Shang Sheng and his [Wanmin Business School] naturally study related knowledge in business finance, national economic adjustment and control, etc.
As for the other one, he is Science Saint.
He plans to use the previous [Method of improving colored glaze], the current [Method of making colored glaze focusing on seawater and sun-salting], and the [Cement] that he has researched but has not yet officially promoted.
In the future, most of the improvements, inventions, creations, etc. that have nothing to do with other Saint vests will all be pushed to Ke Saint!!!
By then, even if it is a hard recommendation, he will be a scientific Saint!!!
At the same time, the future [Wanmin Academy of Sciences] will also be the main academy where he teaches all kinds of modern physics, chemistry, mathematics, etc.
The students of the [Wanmin Academy of Sciences] mainly study modern (Zhao Mo's) scientific knowledge.
It can be said that Yan Changqing had already planned and arranged for these two colleges before they were established.
"Shang Shang and Science Sage, Fan Li and Zhang Heng?!!"
"Wanmin Business School, Wanmin Academy of Science?!!"
Zhu Yuanzhang, as well as the princes Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, silently talked about the two new Saints and the two Saint academy graduates who were about to appear in the Ming Dynasty.
After all, there are peanuts with a 30% oil yield rate, and the [glass-focused seawater sun salt production method] that may produce tens of billions of pounds of salt in the next year.
Then what Yan Changqing said before about creating 10 billion profits, or value, for Zhu Yuanzhang and Ming Dynasty is naturally no longer a lie.
And if this is not a lie, then it means that Yan Changqing spent hundreds of dollars to Zhu Yuanzhang to confirm that the sale of the two Saints at Saint College was established.
If the deal is established, then it is natural that Yan Changqing has already thought about the names of the two future Saints and the college.
