Zhu Houzhao walked in with his hands behind his back, and Liu Jin naturally quickly saluted respectfully.
"No need, no need~"
Zhu Houzhao waved his hand to show that there was no need to be polite, then looked at Liu Jin carefully and said in a low voice: "Tell me the truth, did you do anything dirty outside?"
""
Liu Jin was speechless immediately. Do you think everyone is like you and will die without a woman?
"Your Highness, I have always been with Your Majesty, so how can I have the mind to do those things."
Liu Jin replied speechlessly.
"Haha, let me ask you this."
"You, you, are strict with your wife."
"This life is so short. Enjoy it when you should. Why bother yourself?"
Zhu Houzhao immediately laughed and persuaded Liu Jin, a good man.
"Ahem, does your Highness have anything to do with you?"
Liu Jincai is too lazy to discuss this matter with Zhu Houzhao. Does he have to be like you and have hundreds of women to live his life?
"Yes, yes, let's talk about the business, talk about the business."
After hearing Liu Jin's words, Zhu Houzhao got down to business.
"Come on, follow me to my laboratory. I'll show you my newly developed electric light. It's absolutely shocking."
Zhu Houzhao took Liu Jin outside and prepared to show off to Liu Jin the electric lamp he had researched.
Sitting in the car, Liu Jin followed Zhu Houzhao to his laboratory.
People here in the laboratory are extremely busy, busy doing various electrical experiments. You can see bright electric lamps everywhere. These electric lamps also have glass covers, and they seem to be similar to the electric lamps of later generations.
about there.
The lamp is also quite bright, not comparable to candles and oil lamps.
"Hey, you did a great job. These light bulbs are very bright."
Liu Jin looked at the electric lights and said in surprise.
The electric light has reached this level, which means that it is ready to be used in thousands of households.
"Haha, that's right. It doesn't matter who invented it."
"Hehe~"
"Last time, Lao Liu, you gave us some tips. After inspiration, we did what you said, changed the filament to tungsten filament, and got a vacuum glass bulb for it, and we made these now.
The lights are on."
"The lifespan is very long. It can be lit for thousands of hours. Some of the bulbs have been lit for more than 200 days since they were manufactured, and they still have no problems."
"In addition, its brightness is also very good. As long as the voltage is stable and large enough, the brightness is very good. Compared with candles, oil lamps and the like, it is not a little brighter."
Zhu Houzhao proudly introduced the light bulbs he had developed to Liu Jin in detail.
Originally, bamboo filaments were used to make light bulbs, but the practicality was very poor. After Liu Jin's prompts and inspiration, Zhu Houzhao led his team to conduct many experiments.
It was eventually discovered that tungsten filament was the most suitable for making filaments, and the use of vacuum glass bulbs greatly improved the life and practicality of electric lamps.
It can now be used in the civilian field and can be used to replace candles and lamp oil for lighting.
"Not bad."
Liu Jin nodded while looking at it.
Now that the electric lamp has been developed and the lighting problem has been solved, all kinds of electrical appliances can be produced along with it, such as telephones, electric kettles, fans, etc.
The advent of the era has come into being, which in turn facilitates and enriches people's lives and improves people's productivity.
"Haha~ of course."
Zhu Houzhao's tail is now raised very high, and he is very proud.
"In my opinion, this is already practical and can be promoted to the whole society."
Liu Jin thought for a while and said.
"This is a bit difficult. Electric lights require electricity. If many people use electric lights, they will need a lot of electricity, which requires special power generation equipment. It is impossible for every household to generate electricity by themselves."
When Zhu Houzhao heard this, he immediately shook his head and said.
Although the electric light is good, it seems that it can only be used in laboratories. It is not realistic to enter thousands of households. When every household uses electricity, someone has to step on the engine, which is also very troublesome.
Very tiring thing.
"We can build large-scale power plants specifically for generating electricity, and then send the electricity to thousands of households through lines. Each household does not need to generate its own electricity. It only needs to install lines and switches to use electric lights."
Liu Jin said with a smile.
When the electric light came out, the electrical age was naturally about to begin. It was just electricity. Building a power plant would solve the problem.
If you go to the south where there is a lot of water, you can build a hydroelectric power plant. After it is built, you can just sit back and collect money. Electricity trading is a big business, no worse than any other industry.
After the promotion of electricity, electric lights, telephones, and various electrical appliances can also be produced, which will then drive a wave of economic development, technological development, and progress of the times.
Of course, the most important thing is that you can also make a lot of money.
There are dozens of industries and hundreds of fields related to electrical appliances. It is unknown how many jobs the electrical appliance manufacturing industry alone can create.
As long as it develops, the Ming Dynasty can be considered to have entered the electrical age, and the development of the Ming Dynasty will truly surpass the rest of the entire earth.
"There is no problem in building a power plant, but when it comes to power transmission, if the distance is too long, the power transmission loss will be huge, and the voltage cannot be guaranteed."
Zhu Houzhao touched his chin and said.
He can be said to have reached the forefront of electricity research, and he also knows that long distance transmission is a big problem.
"High-voltage power transmission can be used for power transmission. Using high-voltage power transmission can greatly reduce losses. In addition, we can conduct experiments in Beijing first to accumulate experience and technology, and then promote it on a large scale when the technology matures, even across the country.
Ming Dynasty promotes it."
Liu Jin thought for a while and began to share some of the electrical knowledge and methods of later generations. The problem of power transmission was indeed a big problem in the early days of power development. Some scientists even believed that power could never be transmitted over long distances.
Because the longer the wire, the greater the resistance and the greater the loss. This means that if the line is too long, the power transmitted will eventually be consumed and lost, and voltage is also a big problem.
If the voltage is too low, the light bulb will not be bright enough and some electrical equipment will not be able to operate.
"High voltage transmission?"
"Yes, why didn't I think of this problem? With high-voltage power transmission, the loss can indeed be smaller."
When Zhu Houzhao heard this, he couldn't help but slap his head violently. He seemed to suddenly become enlightened and figured out the problem that he had been confused about all this time.
"But if the voltage is too high, it will be unsafe to use."
"We can study transformers to convert high voltage into low voltage, or low voltage into high voltage, to solve this problem."
"It is converted to high voltage during transmission and converted to low voltage when used at the terminal. This can protect users and increase safety."
"This is very complicated, and we haven't studied much of it yet."
"If there is no research, we can do it now. The best thing to do is get more people involved and try to get everyone to use electric lights as soon as possible."
"There is also a problem with power transmission wires. When electricity is supplied, electric shock is very harmful and may cause death."
"We can wrap the wires with insulating rubber on the outside, which is much safer. We can use high power poles to keep high-voltage transmission lines away from the ground, which is safer."
"Yes~"
Liu Jin kept discussing this matter with Zhu Houzhao, discussing the construction of power plants and the promotion of electric lights. This must be done to prepare for the future. The dawn of the electrical age has begun to illuminate the earth.
