"What's wrong? The acid splashed on my face?" After not coming here for a long time, Hong Tao pushed open the laboratory door and found a very significant change. Li Yaofu's little face had an egg-sized scar on his face, which looked like a burn.

"Well... I'm useless, I exploded the battery box..." Seeing Hong Tao coming in, Li Yaofu immediately felt like he had seen an orphan of his relatives, and water was emitting from his eyes.

"Are you hurting elsewhere? Don't cry, how old you are, you still cry. Look at me, a man is standing in the world, and this face is the most useless. We don't rely on our face to make a living, we rely on our real skills, and we didn't splash into our eyes, right?" Hong Tao hugged Li Yaofu with one arm and patted him on the back. Even if he had cared for it, Hong Tao is a stick when comforting people, and usually he can't be too sad if he doesn't let him comfort him.

"No, I hurt my arms and face... Master, why did that battery box explode?" This time, Hong Tao's comfort really worked. Li Yaofu looked at Hong Tao's face up close, as if he felt that the little scar on his face was nothing. The emperor's face was so dirty, and he could still be an official and find a wife. There was more than one, so what was he afraid of?

"Well, there are many reasons for this. The most likely one is that it is a gas you know, hydrogen! After it is mixed with oxygen to a certain proportion, a small spark will explode. Next time you charge the battery with a hand-crank generator, lengthen the wire a little, and the charging time should not be too long." Hong Tao couldn't say why the battery exploded, because the lead-acid battery he made was too simple, and many reasons would cause it to explode.

Since there is no plastic, rubber, and lead-acid batteries are made of glass tanks, the electrode plates inside are more particular. The lead plates are made of small holes and stuffed with lead paste. With ten percent concentration of dilute sulfuric acid and distilled aqueous solution, the electrode utilization rate and discharge capacity can be greatly improved, but the safety is not guaranteed.

But Hong Tao's understanding of lead-acid batteries ended here. As for how the sealed and maintenance-free lead-acid batteries in later generations were made, he didn't know anything about them, and he didn't even have an impression of them. Who can remove the battery and play with it if you have nothing to do?

The thing he made now is not practical. Although charging and discharging are normal, the system is too fragile. For the time being, the researchers can only be tested in the laboratory, and by the way, they can familiarize themselves with what electricity is. For example, electrolytic water, electrolytic salt water, electrolytic copper purification, electrolytic aluminum, electrolytic alkali solution tests, etc. Through these small experiments, Li Yaofu and others can see for the first time that this invisible current is real and how to do work. They can also memorize and write down some electrolytic formulas.

Hong Tao is not a chemist himself. The chemical knowledge in his mind is fragmented. He cannot teach others step by step like teaching navigation and geography. He can only use this method. He first makes the test process and results, and then let these people slowly explore the principles. No matter what, this is much faster than the method summarized by ancient people bit by bit. Be content.

Although these tests cannot be mass-produced, what is the rough nature of hydrogen? Electrolyzing saturated brine to obtain chlorine, hydrogen, caustic soda, and using crude copper to obtain electrolytic copper with higher purity in copper sulfate electrolyte. These magical reactions are still very charming and even broadening the horizon. It is even the first time I have seen a new material such as aluminum.

Knowing these reactions and having a deeper understanding of electricity, the originally complex chemical preparation process will become simple and efficient. Then, through these reactions, we can gradually find out more compound production rules. Based on three acids and two alkalis, and with some basic petrochemical foundation, Hong Tao doesn't know what these children will produce in another ten or twenty years.

However, if you want to give these children a flying wing, it is not enough to rely on these hand-crank generators alone. Their power is too small, and even if there is a battery pack that can be pressurized and increased the current, it is far from being apart. When I first tried to get a lead-acid battery, I wanted to use a battery pack and a coil to replace a strong permanent magnet, with the purpose of making a larger alternator. Unexpectedly, the alternator was not made, but brought out the primary chemical industry. This is called losing the east corner and getting the muddle of the sacred magnet.

I used to be busy with government affairs and had no time to care about both sides. Now, I am not in office and I am too light. Except for a few days when I go to the navigation school to hold a discussion meeting at the end of each month, I usually have a lot of time for my own control, so why not get back the lost Dongyu? I am idle and find something for myself to do, so as not to sulk at the empty Jinhecheng every day.

If you want a larger generator, it is obviously not enough to use hand tilts alone, and you must find a stronger power source. The power stations in later generations have firepower, and they are not subject to natural conditions and can be built as long as there is enough fuel. But Hong Tao cannot play with this thing. Not to mention the boiler and the blades of the steam turbine can exhaust all the most awesome craftsmen in the world.

In addition to firepower, there is also hydropower generation. Hong Tao wanted to try this model. In principle, ancient people had already used the power of water flow to do work, and wasn't it just a water truck. Compared with hydropower, water trucks are actually more than half of the generator, but they lack the step of energy conversion.

"Now everyone has stopped all their work. I want to build a larger generator. I can't rely on the teacher alone, but I still need everyone's help. I need these materials, so you can prepare them separately." Although Hong Tao has lost his power in the imperial government, he is still a God-like existence in every laboratory. As long as he says he wants to do, no one will object.

If this country was established by him and a group of people through hard work, and the contributions of others were made by others, the proportion was quite large, which was considered collective credit, then these laboratories in Jinhe Kingdom were almost made by him with one person's strength. Although he did not work hard for research and development, every creativity of his ideas could benefit these research and technical personnel for life. So his words must be an imperial edict, and only here is Emperor Hong, the real emperor, one word is the only one!

"Sir, where are you going?" Li Yaofu took the order written by Hong Tao and didn't move. He wanted to follow Hong Tao in an endless manner and see what this god man was going to do. If you look at it less, you may lose the opportunity to become an inventor. This is the consensus of all Jinhe people.

"I'll find a suitable place. It's not suitable for us to put our big generator... You don't need this. I'll go find our police chief and ask him to send me a few guards. Hurry up and prepare. When I find the place, I will teach you how to get the big generator." Hong Tao patted Li Yaofu's head, very proud. Being needed is actually the greatest enjoyment. Looking at the light in their eyes, he felt as happy as he had just finished putting the most beautiful beauty in the world.

After leaving the laboratory on the banks of the Galaxy, Hong Tao did not go directly to the military dock to find a boat to sail, but turned a little bit and reached the commercial dock. This is an open area, which is much lively than Jinhe City. Although there is no bulk goods available for purchase in Jinhewan, there are still endless maritime merchants coming to visit and negotiate business, and there are also people from Jinhe Country.

Since the Great Song Dynasty maritime merchants occupy most of the market share of the marine trade, it is not easy for the residents of Jinhe Country to eat the rice. However, they also have their own advantages, which is that they can use the developed processing industry and technology advantages of Jinhe Country to become suppliers. Many specialties of Jinhe Country cannot be made by others, and they cannot find craftsmen who understand these technologies, but the Jinhe Country merchants can do these things easily. In this way, the shrewd Great Song Dynasty maritime merchants immediately smell the smell of small money. If they can establish a supply relationship with the Jinhe Country merchants, it means that the goods they buy in the future are first-hand, and the price and quality are guaranteed. This is a big deal, and you will stay in Jinhe Bay for a few days without any loss.

In addition, there are several restaurants in the open area of ​​Jinhewan that are unique to the world. It is not that the chefs are skilled, but that the ingredients are too particular and novel. Not only are they selling Chinese food, but they also have dishes from the Dashiguo and Daqin Kingdom. Many foods have never been seen before, even the maritime merchants who travel around the world have never seen them.

Although these dishes are not cheap, it is hard for the merchants to afford it. They can afford it even if they eat several times more expensively. Even if they eat every day, they will not be poor. Inviting guests to have a meal to discuss business is just for peace, safety, pomp and face. What is more respectful than asking someone to come here to eat steamed big crabs from the Great Qin Kingdom, wearing wine from the Great Food Kingdom, and watching Persian dancers twist their waists and squint their hips and thrust their belly?

Moreover, it is safe and efficient. No matter how many enemies you have elsewhere, even if you offend the local government, as long as you don’t violate the laws of Jinhe Kingdom, you can stay here steadily. No one dares to come here to seek revenge. The big turrets on both sides of the river estuary and the warships that cruising day and night outside the river estuary are not vegetarians. Even if you are a wanted criminal in the Song Dynasty, you can live an extremely wonderful life as long as you have money in your pocket. There is no need to photograph others making money. The business of Imperial Bank and Strait Bank is connected, and the business scope is wider. From the Dashi Kingdom to Japan Island, almost every port has an Imperial Bank office. If you save money in one place, you can get it at any time. You don’t even have to see the money. A few small notes can solve the problem.

When I come here to talk about business and meeting customers, it’s just one word, it’s awesome! There’s another word, it’s expensive! There’s another word, it’s a whole!
