At a cinema located in the bustling core area of Hong Kong Island, Zhou Qingyue and several of her classmates came here to watch movies.
Bruce Lee's "Hurricane Rescue 3" is released today. These girls have been waiting for a long time.
Ever since Hurricane Rescue was released in 1969, Zhou Qingyue and the others have fallen in love with the movie.
The second part of the sequel was released soon, but the third part was not released until this year.
Although Zhou Qingyue is a girl, she also likes to watch these hot-blooded movies like popcorn.
Besides, the movies shot by Bruce Lee and others are quite good to watch, and they are good for entertainment and relaxation.
Watching movies and visiting lavender pastures are how Zhou Qingyue spends her summer vacation.
"Oh, dad doesn't write songs for me anymore. Has he forgotten his precious daughter?"
While watching the movie, Zhou Qingyue suddenly thought like this.
As usual, she releases an album every year. This is something she has done every year since she released her first childhood album in 1965.
Every time before an album is released, her father will finish the lyrics and music three months to six months in advance, and then let her practice in advance.
Because she has a lot of study tasks, entertainment time, etc. every day, she can only rest for three to four months during the winter and summer vacations and every weekend.
Naturally, the sooner you can get the songs to practice, the better.
However, her father has disappeared for almost half a month, and no one even responded to text messages sent to him.
There is no doubt that Zhou Jimin is indeed busy at this time, and very busy.
The reason is naturally that research and development has reached a critical juncture and he cannot relax.
An engine with a speed of more than 400 kilometers per hour cannot be used as an aircraft engine, but it can be used as a pure electric vehicle.
He also had a sudden idea. If he couldn't do it himself, he would build an awesome pure electric car and then take the opportunity to build a pure electric engine laboratory.
With such a laboratory, he can unite more scientific researchers to promote the progress of this industry.
Of course, this is not the main purpose.
The main purpose is to persuade the leaders above or attract the military to help.
If there is a place where there are more top scientific researchers, then it has to be the military.
Therefore, a few months ago, Zhou Jimin thought of ways to transform the existing engine technology.
It was mainly about miniaturization, cost reduction, etc., and it also needed to suit the driving experience of the car. It took one month in the real world and five months in the small space world to complete the transformation.
After completing it, he continued to assemble the engine directly on a car.
Purely electric vehicles have great advantages over traditional fuel vehicles.
At present, Zhou Jimin has overcome some difficulties, the most important of which is the battery.
He had already developed lithium-air batteries before. Of course, what he developed at that time was only a miniaturized battery. After all, this thing was to be installed on an electromagnetic gun.
But now it's different. It needs to be installed on a car, and it has great requirements on battery life, power, etc.
Therefore, the battery of a pure electric car can give the car a driving range of more than 1,200 kilometers on the highway.
Even on urban roads, the car's cruising range can reach one thousand kilometers.
Therefore, the battery life of this lithium-air battery is enough to beat all traditional fuel vehicles on the market.
The second is zero ranking. Of course, in the world of the 1970s, many places did not pay much attention to environmental protection issues.
The so-called ozone hole problem was only discovered in 1984. Nowadays, not many people know the dangers of Freon.
After all, chlorofluorocarbons synthesized by humans have been widely used since the 1920s and 1930s.
It has become a refrigerant for refrigeration equipment in many places, household refrigerators and air conditioners, a blowing agent for various types of hard and soft foams in the plastics industry, an aerosol for medical use, hairdressing, and air freshening, and also a product for the tobacco industry.
Tobacco expansion agent, cleaning agent for electronic components, etc.
Such widespread use caused the ozone hole problem over Antarctica in a short period of time.
However, these circumstances will happen sooner or later.
What's more, even if it's not the advantage of zero emissions, just the lack of exhaust gas and noise is very friendly to Oasis New City.
Why?
Because the entire Oasis New City is large, but the green area is larger.
The impact of traditional fuel vehicles on the natural environment is still very large.
If these traditional fuel vehicles can be replaced with pure electric vehicles, it will make a huge contribution to protecting the natural ecology.
Moreover, without fuel vehicles, Oasis New City's demand for oil has been reduced by more than half.
You know, today's Oasis New City consumes a huge amount of oil every quarter.
It is precisely because of these advantages that not long after Zhou Jimin took out this pure electric car, Gu Haishan and the others were eyeing it.
"Professor Zhou, this car of yours is quite strange. It makes almost no noise, and it's so fast. Have you used any noise reduction technology?"
Gu Haishan asked with surprise on his face. He didn't think this car used foreign technology, such as Rolls-Royce or other automotive technology.
There are no cars like Rolls-Royce in the mainland, and Zhou Jimin did not take out these foreign cars from space.
"No, this is an electric car. It doesn't burn oil, it burns electricity."
"Burning electricity?"
Upon hearing this, Gu Haishan's eyes suddenly widened as big as copper bells.
His expression was full of disbelief, and he exclaimed, "How is this possible?"
"Why is it impossible?"
Zhou Jimin chuckled. He did not explain more, but drove the other party directly to the army training ground and found Wang Ping'an and Wang Changwu.
"Comrades Wang, I want to discuss something with you."
When the two heard this, they were curious and happy, and quickly asked what was going on.
"It's like this. I've figured out an electric car, and I'm preparing to continue research and development to see if it's possible to build a purely electric aero engine."
Zhou Jimin didn’t go into too much detail about what happened next.
It is very difficult to build such an engine.
It is normal to have difficulties, so we established an experimental laboratory and everyone worked together.
However, Wang Changwu said that lithium-air battery technology has already been limited. Even if a pure electric engine is developed, it will be of no use.
"Of course it has its uses!" Zhou Jimin shook his head and said:
"Didn't I develop a super lithium-air battery before? Although I haven't found a substitute now, I'm working on it..."
When they heard Zhou Jimin say that he wanted to build a space shuttle with a purely electric engine, and then fly the plane to the moon to search for new elements and substitutes, Wang Changwu and the others were silent for a while.
Gu Haishan thought Zhou Jimin's dream was commendable and courageous, but he didn't agree with it.
Because it's too ridiculous.
In today's Oasis New City, aerospace engineering has almost come to a standstill.
Although satellites are launched into space step by step every year, there is very little progress.
The space station thing was not sent out because they still had too many problems that needed to be solved.
It will be almost impossible to catch up in a short period of time.
In fact, there is no space station in space now.
Previously, the Salute No. 1 launched by the northern bear country was already a tragedy.
And now, the northern bear country continues its efforts and has begun to prepare a Mir space station for launch into space.
Through the name Mir, we can also know what a painful blow the previous Salyut-1 had to Xiong Country’s aerospace industry.
Just some time ago, Bald Eagle also launched a space station called Skylab.
And in order to solve the problem of keeping the space station in contact with the ground at any time, the bald eagle is preparing to contact the astronauts in the space station through radio waves.
However, radio waves can only travel in a straight line and cannot make turns.
However, Skylab flies around the earth every ninety minutes, which means that the time it is in contact with the ground signal station is only six minutes.
Therefore, scientists have no time to collect the required materials.
So engineers established eleven ground signal stations in many places around the world. However, these signal stations can only be built on land, and large areas of ocean areas still have no receivers.
There are many bald eagle researchers, so many solutions have been proposed to solve this problem.
However, Oasis New City cannot solve the problem.
This is also the reason why Zeng Qingfeng and others have been stagnant and have not made leaps and bounds.
Zhou Jimin did not intervene, but let them develop slowly. There are two reasons. One is that there are not enough top scientists, and the other is that he is also very busy.
There are too many projects being carried out, and although they are in full development, they are now completely stagnant.
This is undoubtedly a heavy blow to the entire small town that is used to moving forward at a fast pace.
That's why Zhou Jimin slowed down and took his time.
After all, the small town at this time was developing too fast, but other aspects failed to keep up in time.
Especially in education, many talent gaps are so severe that this is not acceptable.
So how does the Bald Eagle solve the problem of receivers in ocean areas?
At first, the Bald Eagle engineers suggested installing the receiver on the ship.
It's just that the ship's sailing speed is too slow.
So, I finally changed it to the airplane.
Therefore, during that time in May 1973, many airplanes could be seen frequently flying at high altitudes.
These aircraft will have a radio receiving dish with a diameter of two meters at the nose of the aircraft to maintain communication between the ground and the space station.
When the space station comes over the head of the aircraft, the operator will adjust the angle of the receiving dish to obtain the information transmitted back by the space station.
However, the flying speed of the aircraft will definitely not be able to catch up with the space station. Therefore, when the Skylab space station flies out of the range of an aircraft.
The Bald Eagle side will send another plane to take over, so eight planes are needed so that the Bald Eagle side can maintain uninterrupted communication between the ground and the space station.
Zeng Qingfeng and the others have also thought of these methods, but they are of no use and were rejected by Zhou Jimin.
The latter did not mention any satellite communication links, because it involves more powerful artificial satellite aerospace technology.
Such a satellite needs to be launched into a navigation orbit several thousand kilometers above the ground.
You know, the distance between the space station and the ground is four to five hundred kilometers.
However, artificial satellites that can communicate with the ground, space stations, etc. are located thousands of kilometers away from the ground.
A proper dimensionality reduction attack.
Such powerful technology means that more and more powerful top scientists are needed, and there are many such top talents, not just one or two.
Aerospace engineering is about tens of thousands of top geniuses who are often ranked first in the country in moral, intellectual, physical, artistic, and other aspects. After slowly growing up, they become top scientists, and then they get together to complete the project of this undertaking.
.
As long as you score 99 points once, you are unqualified.
After all, whether it is the Jiuquan Satellite Launch Center or the Salyut-1 tragedy in the northern Bear Country, it has sounded the alarm for Zhou Jimin, Zeng Qingfeng and others.
It is precisely because Zeng Qingfeng and so many other scientists have struggled but still have not accomplished something that Zhou Jimin, a professor at Peking University and a computer inventor, actually said that he would build a pure electric space shuttle to go into space?
Gu Haishan admired this, but also disagreed.
The same is true for Wang Changwu and Wang Ping'an, but they very much support Zhou Jimin's approach.
Of course, their support is of no use. You must have the consent of the leaders of the army.
Next, Zhou Jimin took Wang Ping'an to experience what a pure electric system vehicle is.
We also know its acceleration, maximum speed, cruising range, etc.
"By the way, Professor Zhou, what should I do if this car runs out of power? How do I usually charge it? Is it charging fast?"
"You have asked a very good question."
Zhou Jimin said with great appreciation:
"As for the issue of charging, this is what I think. We will build charging piles directly in communities, workplaces, gas stations and other places."
"Of course, the cost may be a bit expensive, but it doesn't matter. As long as we build a factory, the cost will always come down."
"The charging speed of the charging pile can be divided into two modes. One is the normal speed. If it is fully charged, it will take about three to five hours..."
In fact, with this pure electric car, it doesn’t need to be charged for that long.
As long as there is 10% power, the car owner can support the car owner when he returns home or to work, and then directly selects the normal charging speed again.
