"What's going on? Acid spilled on your face? "I haven't been here for a long time, and after Hong Tao pushed open the door of the laboratory, he found a very significant change, Li Yaofu's little face had an egg-sized scar, which looked like a burn.

"Well...... The disciple was useless, and blew up the battery box......" Seeing Hong Tao coming in, Li Yaofu immediately felt like an orphan of his relatives, and his eyes were full of water.

"Did you hurt anywhere else? Don't cry, how old are you, and shed tears. Look at the master, I am a man, and this face is the most useless. We don't rely on our faces to eat, we rely on real skills, and we don't splash in our eyes, right? Hong Tao hugged Li Yaofu with one arm and patted him on the back, even if he cared. On the issue of comforting people, Hong Tao is a mallet, and he usually doesn't let him comfort him and is not too sad.

"No, he hurt his arm and face...... Master, why did that battery box blow up? This time Hong Tao's comfort really worked, Li Yaofu looked at Hong Tao's face closely, as if he felt that this little scar on his face was really nothing. The emperor's face is so spent, and he can still be an official to find a daughter-in-law, and there is more than one, what are you afraid of?

"Well, there are many reasons for this, the most likely is because of a gas you know, hydrogen! After it is mixed with oxygen to a certain proportion, a small spark will deflagrate, and the next time you use a hand-cranked generator to charge the battery, stretch the wire a little longer, and the charging time should not be too long. "Why did the battery explode, Hong Tao can't say, because the lead-acid battery he made out is too simple, and many reasons will make it explode.

Because there is no plastic, rubber, lead-acid battery is made of glass trough shell, the inside of the plate is more particular, the lead plate is full of small holes, plugged into the lead paste made, with 10% concentration of dilute sulfuric acid and distilled water solution, the electrode utilization rate and discharge capacity can be increased a lot, but the safety is not guaranteed.

But Hong Tao's understanding of lead-acid batteries ends here, as for how to get the sealed, maintenance-free lead-acid batteries in later generations, and what tricks are in them, he doesn't know, he doesn't even have an impression, who has nothing to do with dismantling the battery to play.

Now he made this thing is not practical, although the charging and discharging are normal, but the system is too fragile, and can only be tested in the laboratory for the time being, by the way, let these researchers be familiar with what electricity is. For example, electrolysis of water, electrolysis of salt water, electrolysis of purified copper, electrolysis of aluminum, electrolysis of caustic soda solution and so on. Through these small experiments, Li Yaofu and others can intuitively see for the first time that this invisible current is real and how it works, and they can also memorize some electrolytic formulas.

Hong Tao himself is not a chemist, and the chemical knowledge in his mind is all fragmentary, and he cannot teach others from shallow to deep and step by step like teaching navigation and geography, so he can only use this method. First make the test process and results, and then let these people slowly explore the principle, anyway, this is much faster than the method of the ancients to summarize little by little, be content.

Although these tests cannot be mass-produced, the approximate properties of hydrogen, the electrolysis of saturated brine to obtain chlorine, hydrogen, caustic soda, and the use of blister copper in the copper sulfate electrolyte to obtain higher purity electrolytic copper, these trick-like reactions are still very fascinating, more eye-opening, and even the first time I saw the new material aluminum.

Knowing these reactions, and with a deeper understanding of electricity, the otherwise complex chemical preparation process becomes simple and efficient. Then, through these reactions, more compounds can be gradually explored. On the basis of three acids and two alkalis, and a little basic petrochemical foundation, Hong Tao doesn't know what these children will come up with in another ten or twenty years.

But if you want to give these children wings to fly, these hand-cranked generators alone are not enough. Their power is so small that even if there is a battery pack that can be pressurized to increase the current, it is far behind. At the beginning, I tossed out the sulfuric acid, mainly to get a lead-acid battery, and then use a battery pack and coil to replace the strong permanent magnet, the purpose is to make a larger alternator. I didn't expect the alternator to come out, but it brought out the primary chemical industry, which is called the lost east corner and the harvest of mulberry elm.

In the past, I was busy with government affairs, and I didn't have time to take care of both ends, but now I am unofficial and light, except for going to the navigation school at the end of each month to hold a discussion meeting for a few days, I usually have a lot of time at my disposal, so why not get back the lost EAST? Being idle is also idle, find something to do for yourself, and save yourself from sulking when you see the empty Jinhe City every day.

If you want a larger generator, it is obviously no longer enough to rely on hand crank and foot pedals, and you must find a more powerful power source. Later generations of power stations were capable of firepower, which were not constrained by natural conditions and could be built as long as there was enough fuel. But this thing can't be played, not to mention the boiler, the blades of the steam turbine can exhaust the world's most awesome craftsmen to death.

In addition to firepower, there is also hydroelectric power, and this model Hongtao would like to try. In principle, in fact, the ancients have been using the power of water to do work for a long time, and the waterwheel is not it. Compared with hydroelectric power, the waterwheel is actually more than half a generator, but it lacks the step of energy conversion.

"Now that everyone has stopped what they are doing, I want to build a bigger generator, and I can't do it by the teacher alone, and I need everyone's help. I need these materials, and you guys go their separate ways to prepare them. "Don't look at Hong Tao has lost his power in the imperial government, but he is still a god-like existence in every laboratory, as long as he says what he wants to do, no one will object.

If this country was established by him and a group of people through hard work, and there are other people's contributions in it, accounting for a large proportion of it, which can be regarded as a collective credit, then these laboratories in Jinhe Country are almost made by him alone. Don't look at him to work hard to engage in research and development, but every idea he has can benefit these research and technical personnel for life. So his words must be a holy decree, and only here, Emperor Hong is the real emperor, every word!

"Where are you going, sir?" Li Yaofu took the list written by Hong Tao and didn't move, he wanted to follow Hong Tao every inch to see what this god man was going to do. If you don't look at it once, you may lose an opportunity to become an inventor, which is the consensus of all Jinhe people.

"I'm going to find a suitable place, it's not suitable for our big generator...... I don't need you to do this, I'll go to our police chief and ask him to send me a few guards. Let's go and prepare, and when I find a place, I'll teach you how to make a 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 is as cool as just finishing the most beautiful beauty in the world.

Leaving the laboratory on the shore of the galaxy, Hong Tao did not go directly to the military dock to find a ship to sail, but turned a little corner and slipped to the commercial dock. This is an open area, much more lively than Jinhe City, although Jinhe Bay does not have any bulk goods to purchase, but the maritime merchants who come for sightseeing and business negotiations are still endless, and there is no lack of people from Jinhe Country.

Since the maritime merchants of the Great Song Dynasty occupied most of the market share of the maritime trade, it was not easy for the residents of Jinhe Kingdom to eat the bowl of rice of the maritime merchants. But they also have their own advantages, that is, they can take advantage of the developed processing industry and scientific and technological advantages of Jinhe Country to become suppliers. Many of the specialties of the Golden River Country cannot be made by others, and there are no craftsmen who understand these techniques, but the merchants of the Golden River Country can easily do these things. In this way, the shrewd Great Song maritime merchants immediately smelled the smell of small money. If you can establish a supply relationship with the merchants of Jinhe Kingdom, it means that the goods you buy in the future are first-hand, and the price and quality are guaranteed. This is a big deal, and it is not a loss to stay in Jinhewan for a few days.

In addition, there are several restaurants in the open area of Jinhe Bay, which are also unique in the world, not to say how exquisite the chef's skills are, but to use materials and ingredients that are too particular and too novel. Not only does it sell Chinese food, but it also sells dishes from the Great Food Kingdom and the Great Qin Kingdom, and many foods have never been seen, even the maritime merchants who have traveled from south to north have never seen it.

Although the prices of these dishes are not cheap, this is not difficult for maritime merchants, no matter how expensive they are, they can afford to eat, even if they eat every day. Inviting guests to eat and talk about business, isn't it just to be quiet, safe, pompous and face-saving, what is more face-saving than inviting someone here to eat cheese steamed crabs from the Great Qin Kingdom, the wine of the Great Food Country, and watching the Persian dancers twist their waists and shake their hips and straighten their bellies?

And it's safe and efficient here, 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 batteries on both sides of the estuary and the warships that cruise day and night outside the estuary are not vegetarian. Even if you are a wanted criminal in the Great Song Dynasty, as long as you have money in your pocket here, you can live an extremely wonderful life. There is no need to pat the idea of others beating you for money, the business of the Imperial Bank and the Straits Bank is connected, and the business scope is more extensive, from the Great Food Country to the Japanese island, almost every port has an office of the Imperial Bank, and if you deposit money in one place, you can access it at any time, and you don't even need to see the money, a few small notes can solve the problem.

Come here to talk about buying and selling, it's just one word, cool! There is one more word, expensive! And one more word, all!
