After showing the capacitors, Guo Kang showed them various coils, metal sheets and other devices.
"In addition to making these finished products, the materials themselves for making them will also be a major research direction in the future." Guo Kang reminded them: "Do you know why I was short of money before, even the Patriarch's funding was not enough? "
"Are these devices expensive?" asked a monk.
"Yes." Guo Kang nodded: "For example, this thing."
He picked up a coil, and the monks discovered that it did not have cotton threads sandwiched between copper wires like other coils; moreover, the coil seemed to have more than one layer, and was densely packed and thickly wrapped.
"This is the densest coil we can do so far." Guo Kang said: "We need to ensure that the copper wires do not contact each other, otherwise the electricity will not pass through the circles of copper wires, but directly from the contact. The place will flow away. Previously, cotton wire soaked in oil was used and sandwiched in the middle to prevent the two sides from touching. Cotton cloth brushed with mineral oil or asphalt should also be placed between the two layers of copper wire. This will increase the volume. and weight.”
"The method I thought of before was to paint on it like this." He pointed to the black shell on the surface of the copper wire: "Just leave a slight gap between the two wires. Wrap it around and wait for the paint to dry. A non-conductive hard shell will be formed, and then a second winding will be wrapped around it. This can save a lot of space and weight compared to the previous one.”
"But we don't have this kind of thing, only the Ming Dynasty and the Javanese Yuan have it - for this little trial, I bought it from Sun Shiwan at a high price."
"When making large quantities, we can only use shellac instead." He picked up another one with a purple shell: "But shellac is not a cheap thing. This thing is produced in India, and it also has to be imported."
"Then, this zinc sheet was used to make batteries just now." He picked up a metal sheet and said: "We can only make alloys here. Only India and the Ming Dynasty can produce pure zinc. It also has to be imported."
"And this." He pulled out a porcelain cylinder: "Compared to the pottery here, this dense, non-absorbent porcelain is actually more suitable. But this one also has to be imported."
"Wait a minute. Can't we even make porcelain?" Tuo Huan asked.
"The core of porcelain is the high-temperature kiln. It is very large and requires the joint efforts of many professional craftsmen to complete it." Guo Kang said: "Most of our craftsmen left the Central Plains in scattered and large-scale teams, and they are also in the military and water conservancy fields. Lord, I’m not very good at this.”
"You see, products such as paper and gunpowder have long been spread by craftsmen traveling to the west, but now in the whole world, only the Ming Dynasty and the Javanese Dynasty have the ability to make porcelain, and even the Japanese yen can barely make it."
"Silk was spread because of the outflow of silkworm seeds. But porcelain is really not good." He gave an example: "During the Yuan Dynasty, the Portuguese obtained kaolin and the process of firing porcelain, but I tried again after returning to China and still failed.”
"This thing is, I give you raw materials, give you instructions, and teach you how to cook, but you can't cook it." He shook his head repeatedly: "I know this may sound strange, but the reality is like this. In Europe, if you want to cook something real Porcelain will have to wait hundreds of years."
"It's really terrible to say that." Tuo Huan understood what he meant: "Hey, we have lost too many skills. Now except farming and fighting, I feel like I am not good at anything."
"We have to buy everything. It's okay now, but what will happen when we need to produce in large quantities in the future?" He said worriedly: "The war there is not going to stop, and the stock may be out of stock at any time. We still have to find a way to make it ourselves. Just come out."
"As for batteries, I currently have an alternative." Guo Kang said: "I tried to use lead and sulfuric acid to make batteries. The lead is used as one pole, and the red lead is processed to make the other pole. This solution may be better, but it is also more difficult. ”
"As long as there is a method." Tuo Huan was open-minded: "I think this idea is good. We Romans are very good at playing with each other. This is to use our strengths and avoid our weaknesses."
Among the priests, several are experts in cultivating local crops, and some are craftsmen in the village. They are happy to accept these jobs.
After some discussion, everyone quickly decided that they should work harder in this regard to strive for an early breakthrough and solve the problem of key technologies being choked by Eastern powers.
After discussing this, Guo Kang took them out of the chapel.
"We are going to the workshop next." He told everyone: "There is nothing special about ordinary workshops, but there is a workshop in the distance that produces various materials and equipment, which requires the use of various chemicals... Oh, it is alchemy. Craftsmanship.”
"I believe that proper study of alchemical technology will also play a great role in understanding the world and understanding the 'Logos' behind all things. Unfortunately, many alchemists are now obsessed with ancient pagan superstitions and have no understanding of the truly important laws and regulations. Theoretical analysis work, but I don’t pay attention to it.”
"You are all devout people serving Heavenly Father. I believe you will know very well what we really need to do." He took the opportunity to encourage: "I hope we can find something from it, or at least provide support for other research."
"In addition, there are many dangerous substances there, so be careful when visiting and researching."
After hearing what he said, the priests all expressed that they understood and would not mess around like ordinary alchemists.
Guo Kang nodded with satisfaction and led them in another direction.
On the way, the priests discovered that there was another building not far from the chapel. There is also a huge bronze Heavenly Brother standing on the top of it. However, what is behind this Heavenly Brother is not a traditional Greek cross, but a Ross Cross with three horizontal crosses. If you look carefully, you can see that there is a slide rail behind Brother Tian, and the rope on his hand is also movable and can move up and down.
Now, Brother Tian is lowered a little and hung a little below the main cross arm. Since the arms are also stretched flat, there are four horizontal lines appearing at the same time, which makes it look unique.
"What is that?" Brother Dmitry thought it was strange at first, but after thinking about it carefully, he saw a lot of things beyond his imagination today, which showed that he still had a lot of theological knowledge that he didn't know. So he humbly asked for advice.
"Oh, that's the canteen." Guo Kang said: "That building and the bronze sculptures on it were not directly allocated, but were jointly funded and donated by several people. The Ross Church took the lead, so it was made That’s it.”
"The cafeteria also has a special function, but it is very immature. I originally planned to talk about it later, but since you are interested, let's drop in and have a look."
He said, leading everyone over.
When they walked to the building, everyone discovered that there was a nameplate with Latin characters on the base of the statue. It reads: "GRATIOSVS", "GENEROSVS", "GLORIOSVS", "GAVISVS", "GRANDIS".
"What is this?" Tuo Huan asked, not knowing Latin.
"They are: gracious, noble, glorious, joyful, and great." Guo Kang replied: "When the statue was ordered, an Italian lady also paid a huge sum of money. These are the eulogies she selected. Carve it here as a memorial to Brother Tian.”
"This is also one of the core parts of the equipment. I will show you. This part -" he waved his hand and introduced: "I see that these words all start with 'G', so I habitually call them abbreviations. For '5G Heavenly Brother'."
