Chapter 492 Xu Guoxu was scalded

Not only Xu Guoxu was curious, but also King Anyi was also very curious. He only met Wang Kuang after he became famous. He had never encountered many legends of Wang Kuang in the past, especially when he heard that the reason why the building ship could go out to sea was that Wang Kuang made great contributions. Therefore, he was always full of expectations for the good things that Wang Kuang could produce under his command. After being exposed, Wang Kuang also launched many things, but he only knew after it was spread. Therefore, it was his regret that he could not witness the birth of one thing before he became famous. Now, this opportunity is right in front of him, so how could he let it go?

It is impossible to resist Xu Guoxu, and seeing that the sun has not set, it is still almost an hour before it has been. At this time, the opening of the camp is aimed at the west side. If the sun stove is supported at this time, it is unlikely to cook things, but it is still possible to cook a pot of water. The people present are basically reliable. Although An Yi King is a foreign king, he cannot reveal the news about the sun stove. (dukank Novel Network

Moreover, according to Wang Qun's plan, if the cost of the sun stove can be further reduced and mass-made in the future, it can also be equipped to the army. Imagine that in the snowy wasteland, especially on the grassland and in the desert, it is difficult to find firewood. At this time, if a sun stove can be set up, a pot of water can be boiled, and the soldiers can drink a sip of hot hot water, the maintenance of combat effectiveness will definitely be effective, especially some wounded soldiers, and the demand for hot water will be greater.

If the sun stove can be equipped in the army, if each fire can be equipped with a sun stove, it will further reduce the burden of logistics support, and there is no need to send many people to search for firewood everywhere. This will not show an advantage in summer and autumn, but in winter and spring, especially on the grasslands in the cold winter, the advantages will be very obvious. In other words, if the sun stove is equipped, the military supplies of the troops can free up a lot of manpower and material resources to prepare consumables such as arrows.

Wang Kuang didn't expect to change the comparison of the combat power between the enemy and us by relying on two things. However, if one is not good, I'm just two, two is not good, I'm just three, three is not good, I'm just ten. With the support of so many new technologies and new products, here one bit and there will accumulate a drop of a little, and it will always affect the battle. Including the seven weapons that Wang Kuang had collected for the Tang army in the previous period, this Sun stove is the eighth weapon prepared by Wang Kuang. If the new swordsman in Dongping are equipped with a large number of equipment into the army, then there will be nine changes. Wang Kuang doesn't believe it. The Tang army with nine changes will not have a qualitative improvement against the backward tribal armies in the north. Not to mention the army in the north, even against the Western Roman Empire at this time, Wang Kuang also believes that the Tang army will definitely have the upper hand.

It can be said that the Tang army is far ahead of other countries in addition to the weakness of horses. The improvement of horses and the introduction of excellent breeds of military horses is also an important task and a secret task of the imperial village. In fact, it can be said that most of the income of the imperial village after the success of the improved species in the future will be devoted to the improvement of horse breeds. However, Wang Kuang did not understand the improvement of horse breeds, so he didn't ask about it. Instead, the imperial court secretly solicited horse breeders from all over the country to experiment and work hard.

"Since I'm going to try, then try it. But the sun is about to set, and cooking things is not enough, but it's okay to cook water." Wang Kuang couldn't resist and ordered two guards to carry the sun stove under the sun to unfold. This was the first sun stove made. It was not small and it looked like a hundred pounds. It was because it was too heavy that Wang Kuang did not immediately push it to the Ministry of War. In Wang Kuang's idea, the weight must be reduced to less than 30 to 40 pounds. That is, if the bronze mirror, which is the main weight, can be replaced by thin copper sheets, and this thin copper sheet also uses the mercury plating process of the copper mirror, the sun stove body is replaced with linen to further reduce the weight and equip it to the army. During this period, Pu Xiliang was busy with improving work. What should be done is Pu Xiliang's business, and Wang Kuang did not intend to participate in it.

The sixteen solar stove bodies are connected by hinges (hinges have appeared in the Han Dynasty, and many unearthed ancient tombs of the Han Dynasty have appeared). It is also very convenient to unfold. After unfolding, put them on a shelf, and then insert the other end of the three legs connected to the edge of the sun stove into the three sockets on the edge of the stove that Wang Kuang took out. One sun stove is assembled, adjust the position, aim it at the sun, and then put a pot filled with water on the stove.

With just a stick of incense, the pot of water started to heat up, and it was about to start. Xu Guoxu reached out and went to the bottom of the pot and found out: "It's so strange, can you boil water without fire?" Wang Kuang didn't hold it back. It was too late. As soon as Xu Guoxu finished speaking, he shouted: "It hurts my family!" The hand rushed back quickly, but it was already red.

Now, King An Yi quickly retracted his hand. He originally wanted to learn from Xu Guoxu and stretched out his hand to try it. Now, seeing Xu Guoxu like this, he was scared and sweating in his back.

"Why are you so careless?" Wang Kuang complained urgently. If the focus of sunlight can be accurately controlled, even iron can melt if it can accurately control the focus. Many people have conducted experiments in this regard, illuminating the sunlight reflected by a fine curved mirror onto an iron sheet. In a few seconds, the iron sheet was burned through a big hole. Fortunately, the current sun stove is not as good as the manufacturing process is not up to standard, and the light reflected by each lens cannot be concentrated at a point, but even so, how can the heat be counteracted by the flesh and blood?

Fortunately, the guards who fetched the water had also returned. They found a mountain stream. The water in the mountain stream was cold and boneless in this summer. Wang Kuang hurriedly used the soldiers to get the water and slowly poured it on Xu Guoxu's burned hands to cool him down. After the naan water was poured, Xu Guoxu was wiped dry and then applied sesame oil (it is very useful to apply sesame oil to burn and scalds. The main ingredient of the scald and burn ointment sold on the market is sesame oil. If everyone is hot at home, if they are splashed by hot oil, as long as the skin is not broken, they can apply sesame oil, and it will be almost gone in three or four days).

Fortunately, Xu Guoxu's reaction was not slow. As soon as he felt the flow, he quickly pulled his hand back. The sun stove's light-gathering effect was not so accurate. These two points are the reason why Xu Guoxu saved his hand. His skin was not taken off and he was burnt. He was just red and laughed as a "braised pig hand" by Wang Kuang. Such injuries were not cured for ten or eight days. Fortunately, it was his left hand, which had not had a great impact on his daily life. He went to Jian'an all the way to Jian'an. He didn't need to do anything to eat. He built a camp and other work, and Wang Kuang and An Yi's guards came to do it. He also brought a few small yellow gates to serve him. Therefore, the hand injury was not damaged, and there was no difference.

After such a big embarrassment, Xu Guoxu naturally ordered several small yellow sects to keep their mouths tight after they arrived in Jian'an and returned to Chang'an. Then he asked Wang Kuang: "Erlang, how did you do this? Are you really the Star Lord who came down to earth? He could actually make fire from a distance?"

At this time, the water in the pot had already started, and Wang Kuang did not take it off, but pulled Xu Guoxu over and pointed to the bottom of the pot to show him: "Do you see, is this bottom of the pot much brighter than elsewhere? In fact, it is very simple. I just concentrated all the sunlight on this point. Think about it, let alone summer, winter, no matter how cold it is, people feel warm in the warm sun. This is still the sunlight shining evenly on you. If all the sunlight is concentrated on one point, the temperature will naturally be higher. Therefore, this is called the sun stove. Convenient is convenient, but the disadvantage is that there must be sunlight." The word sun does not specifically refer to the sun at this time, so Wang Kuang gave the sun stove the name of the sun stove. When he first named this name, he also called it "The sunlight rose purple smoke from the sun stove".

After saying this, Xu Guoxu also understood: "So, then in the future, this sun stove will be installed on the boat. If there is a sunshine, use this sun stove. If it is rainy, use firewood? This is good, and it can indeed save a lot of firewood, wood and carbon. This method is wonderful, and it is amazing."

In fact, Wang Kuang thought further than Xu Guoxu. His plan was to use stone carbon balls for the bottom bay of the building ship in the future. One stone carbon ball is heavier than wood carbon, and the other is that the stone carbon ball itself has a higher combustion value under wet conditions and is easier to ignite. However, this humidity also has a certain limit, and the wet the better. However, it is precisely this characteristic of stone carbon that makes it only need to be placed in a dry place and dried for a few days after being wet. It is not like wood carbon, which is soaked in water. If it has not been exposed to the sun, it must be dried for more than a month before use. This is not very obvious on land, but at sea, the advantages and disadvantages of the two are distinguished at once.

The successful boiling of the sun stove attracted many guards to watch, and Wang Kuang did not stop him. Only the Tang Dynasty could have such a product. Even those Hu people, people from the storm or the stick were present. Wang Kuang was not afraid even if he explained the principles in detail. At this time, the countries around the Tang Dynasty could not even make bronze mirrors. Their bronze mirrors were purchased from the Tang Dynasty. Therefore, even if these foreign tribes got the technology, they could not make them. Even if they were made, they would have to be extremely expensive and could not be promoted. They could only be regarded as novel toys of the nobles. This is like Ah San. Even if they got the manufacturing technology of the aircraft carrier and the drawings, their aircraft carrier would still be far away. Why? Because they did not have a matching processing technology!

The solar stove was also tried, and Xu Guoxu was accidentally burned and stayed away from the solar stove. At this time, the sun had already set on the top of the mountain in the distance, so it was no longer suitable for using the solar stove. Wang Kuang asked the guard to put it away. After putting it away, Xu Guoxu dared to touch the solar stove. While he touched it, he kept tsk: "Is this thing good? Is this thing good?"

King Anyi's eyes were also shining. Although he had already become the king, after all, Liuqiu people still belonged to his people. His fiefdom was still Liuqiu in name. Moreover, in Liuqiu people, he was still Liuqiu King. Liuqiu was windy and rainy, and there were not many mountains and forests on several islands. In Liuqiu, it can be said that the value of firewood and the value of food are comparable. If this sun stove can be introduced to Liuqiu, it will definitely be able to solve many problems for the people. He stumbled a few times, but finally couldn't resist the temptation. He asked Wang Kuang: "Marquis Jian'an, don't you know what the price of this sun stove is? I want to buy some."

Wang Kuang changed his mind and knew what King Anyi was thinking. He smiled and said, "Whatever you buy? Liu Qiu people are also the people of the Tang Dynasty. If you want the whole Tang Dynasty, you don't have this energy. But if you say that every household in Liu Qiu has such a sun stove, you can also take it out. In this way, someone brought this sun stove back to Jian'an to get the craftsmen from Dongzhigang to imitate it. Let them imitate more and give it to Liu Qiu."

Liuqiu has a population of only 10,000. If it is calculated by five people per household, it is only more than 2,000 households. If you use the solar stove in a residential house, you don’t have to consider the lightness. As long as you can adjust the angle at any time, it’s enough. Therefore, the cost of a solar stove is only a few dozen cents. It’s less than 100,000 cents for the residents of Liuqiu. This little money can be easily taken out now. Not to mention anything else, the income from Shanwaishan brings him more than 100,000 cents every year.

As we were talking here, we heard the guards on the outside shouting: "Stop!"
