Daming: The system rejected my request for salted fish

No one expected that they would have to wait until eleven o'clock before the person finally showed up.

However, no one complained about this situation. After all, a higher-ranking official can crush someone more powerful than him, not to mention that Wei Wu was the boss of the Academy of Science and Technology.

In addition to his other identity, he can be said to be the mentor of all the craftsmen in the Academy of Science and Technology.

In ancient times, the value of a mentor was very high, and his status was only slightly lower than that of one’s parents.

Just waiting a little bit is nothing to them. They suffered a lot when they were learning the craft.

Even for this, one still needs to go through rigorous tests from a mentor before one can acquire even a hint of the true craftsmanship.

However, Wei Wu did not make any demands on them and taught them all the knowledge he had without reservation.

This alone is enough to make these craftsmen grateful and remember it in their hearts for the rest of their lives.

But this was just the idea in the minds of the craftsmen, and Wei Wu himself did not have such an idea.

As a modern person, I felt a little embarrassed when I walked in and saw these people standing in the sun waiting for me.

"Well, I haven't seen my family for a long time, so I inevitably want to stay home for a while. I'm sorry to have kept everyone waiting."

Hearing Wei Wu's apology, the craftsmen dared not accept it. Song Zhong even shook his hands and said:

"I wouldn't dare, the Vice President has been away from Beijing for so long, he deserves to spend more time with his family. It's only natural, right?"

As soon as Song Zhong finished speaking, the other craftsmen followed suit, and their words were similar in meaning.

Seeing this, Wei Wu no longer worried about being late, and turned to look at Sun Chang and asked about the business.

"Sun Chang, is there any problem with the generator assembly?"

"Reporting to the Vice President, following your instructions yesterday, we have assembled the generator and have also tested it."

"Oh? You've already taken the test? How did you do it?"

"I connected the rotor shaft of the generator to the steam engine and tried it out. It worked great!

After hearing what Sun Chang said, Wei Wu couldn't help but exclaim in his heart.

Oh my god! This guy is really talented!

Back then, he and Song Zhong worked together and together they came up with the idea of ​​a triple expansion steam engine.

Nowadays, we can even think of using the balanced power of the steam engine to connect the generator to test whether it is operating normally.

Wei Wu couldn't help but sigh in his heart that the wisdom of the ancients should not be underestimated!

In fact, what Wei Wu didn't know was that when testing the generator, Sun Chang also thought about whether it was possible to use a steam engine to generate electricity.

It's such a simple truth that Wei Wu, as a teacher, couldn't have been unaware of it, but he didn't say it out loud.

Since Wei Wu didn't say anything, there must be some disadvantages, Sun Chang thought to himself.

In fact, it is not impossible to directly use the power of the steam engine to generate electricity, and Wei Wu has thought of it.

Simply put, it’s not that it can’t be done, but that Wei Wu doesn’t want to do it.

The main reason is that the energy conversion efficiency of using a steam engine connected to a generator is so low that it is unnecessary.

The thermal energy is first converted into mechanical energy through the boiler, and then the mechanical energy is converted into electrical energy through the generator.

Fuel needs to be added to the boiler every once in a while, and most of the energy is wasted.

Not only is it troublesome, but it also produces a lot of smoke and exhaust gas, making the Institute of Science and Technology smoky and foul.

Anyway, the Institute of Science and Technology is next to the Yangtze River, so it not only does not require any fuel, but can also generate electricity uninterruptedly.

There is a ready-made water source available, so why go so far away like a fool?

Steam engines could be used to generate electricity in emergencies, but in the long run, hydropower was the best option.

Regarding this point, Wei Wu originally planned to wait until the power station was officially put into operation before explaining it to these craftsmen.

However, since Sun Chang had already tried it, Wei Wu thought it would be better to give him a reminder first.

"I'm glad you thought of using steam engines to generate electricity, but remember, this should only be done in emergencies. Under normal circumstances, hydropower will suffice."

"Yes, I will remember that."

Sun Chang responded with a serious expression, and then spoke again:

"Vice President, the generator and the propeller-like turbine have been transported to the hydroelectric power station."

"The people over there are ready. As soon as you arrive, they can start the installation work immediately."

Hearing this, Wei Wu nodded with satisfaction.

"Great! I'm really looking forward to it!"

Afterwards, under the leadership of Song Zhong, all the craftsmen from the Academy of Science and Technology followed Wei Wu to the riverside.

Fortunately, the Institute of Science and Technology is right next to the Yangtze River, otherwise it would be really troublesome to use a hydropower station to supply electricity to the Institute of Science and Technology.

The main issue is not construction, but the issue of supplying electricity to the Institute of Science and Technology after the hydropower station is put into operation.

Wei Wu didn't have any wires in his hands, but they were all disassembled from various electrical appliances. They were fine for experiments, but they were not enough to transmit electricity.

Therefore, the Institute of Science and Technology uses enameled copper wire, which means the copper wire is soaked in natural lacquer, and an insulating layer is formed after the paint dries.

However, this method is not safe. There are too many uncontrollable factors when the enameled copper wire is exposed, and the varnish is likely to be removed.

Therefore, while connecting the copper wire back to the Institute of Science and Technology, secondary preparations need to be made outside the copper wire.

Use bamboo tubes or wooden tubes to splice, make waterproof and moisture-proof preparations at the interface, and then pass the varnished copper wire through it.

Finally, bury it underground so that you don’t have to worry about it being damaged by wild animals or humans.

Although this method is not perfect and requires frequent checks for problems, it is currently the best option.

Unless Wei Wu opens a barrel of wires from a courier, or can find a rubber tree to harvest natural rubber.

The problem is that Wei Wu's express delivery depends on luck. No one knows when it will be delivered, not to mention the rubber trees.

During this period, rubber trees were still growing in Brazil and had not even entered Asia, let alone the territory of the Ming Dynasty.

Therefore, using enameled copper wire and a long wooden tube is a last resort.

The group arrived at the riverside, and before they got too close, Wei Wu had already seen the gray-white concrete building.

I have to say that the craftsmanship of the craftsmen in the construction team is really amazing.

The hydropower station in front of me is much better looking than the one Wei Wu drew at the beginning, and its construction is also very standard.
