But this has marked that Long Yan has opened the door to the electrical age.
After Liu Zheng learned the news, he felt happy. In the era before he traveled through time, the world had become prosperous due to the application of electricity.
Countless things made with electricity can run, which will greatly reduce the cost of manpower.
But now there is a question: if electricity is available, what can it do?
Liu Zheng knew that electricity could heat, drive cars, cool refrigerators, etc...
However, Liu Zheng only knew little about the research on these electrical appliances.
The electrical appliance he is most familiar with is the light bulb.
However, it is also very difficult to produce the lowest-level incandescent lamps of previous generations with current technology.
After the construction of the thermal power plant was completed, the scientists from the Liangzhou Experiment came to ask Liu Zheng not just once, but Liu Zheng was also worried about this.
"Sir, what is the use of the thermal generator you asked us to research? We can't always use it to attract pieces of paper."
"We may have other uses, such as using electromagnetism to create small rotations...that kind of thing?"
Liu Zheng said: "Is it something similar to a hand-operated generator, except that it is driven by electricity?"
"Yes, yes, that's it. I want to use this rotational force to make a cutting machine. After all, the efficiency of cutting trees by human power is too slow."
Liu Zheng nodded and told him: "Your idea is very good, but we have to consider our current control over electricity and our ability to reach the technical level you mentioned."
"You can do some simple things now, such as researching the telegraph machine."
Hearing such an answer, the scientist was not disheartened. He even felt that Liu Zheng was right.
After all, it is very difficult to realize such an invention, and they currently have very little control over electricity.
After thinking of this, he then said: "So Mr. Liu, do you have any better ideas for the research on electrical appliances?"
My thoughts are light bulbs…
Liu Zheng smiled and said: "I am working on something that can turn night into day. It is a luminous thing. I call it a light bulb."
After hearing this idea from Mr. Liu Zheng, the researcher murmured: "Light bulb..."
Nowadays, lanterns are relied on for lighting at night, but lanterns with flames are prone to problems.
It often even causes fires.
The researcher nodded and said: "Sir, your invention may be able to change the world."
Liu Zheng smiled and said nothing. He naturally knew what significance the invention of the light bulb brought to the world.
But now he still has some technical difficulties that he has not yet solved, because he has already mastered this popular knowledge.
It was not difficult at all for Liu Zheng to make a light bulb.
Just connect the tungsten wire to the wire and use the resistance to make it light up.
But the difficulty is how to keep the tungsten wire from contacting the outside air.
Tungsten wire can easily ignite air under the temperature of electricity.
He still had no way to solve the problem of how to insert a tungsten filament bulb into a vacuum environment without air without pumping out air.
For him, such questions are a bit difficult.
Until he recalled a report he had read before, the first incandescent lamp developed had air inside.
