1937, July, Hong Kong Island.

A movie theater in the bustling core area of Hong Kong Island, where Zhou Qingyue and several of her classmates came to watch movies.

Bruce Lee's Hurricane Rescue III was released today, and they are girls, but they have been waiting for a long time.

Since the release of the hurricane rescue in 69, Zhou Qingyue and her sisters have liked this movie.

The second part of the sequel was released soon, but the third part didn't start until this year.

Although Zhou Qingyue is a girl, she also likes to watch these popcorn-like movies.

Besides, the movies made by Bruce Lee and them are already very good-looking, and it's good to have fun and relax.

Watching movies and visiting lavender ranches are all ways for Zhou Qingyue to spend this summer vacation.

"Alas, my father doesn't write songs for me anymore, has he forgotten all his precious daughters?"

When watching the movie, Zhou Qingyue suddenly thought so.

Traditionally, she releases an album every year, something she's done every year since she released her first childhood album in '65.

Before every album is released, her father will do a good job of writing and music about three months to half a year in advance, and then let her practice in advance.

Because she has a lot of study tasks every day, as well as entertainment time, etc., she can only rest for three or four months during the winter and summer vacations and every weekend.

Naturally, the sooner you get the song and practice it, the better.

However, her father has disappeared for almost half a month, and no one has responded to even texting him.

There is no doubt that Zhou Jimin at this time is indeed busy, and very busy.

The reason is naturally that R&D has reached a critical juncture, and he can't relax.

The engine with a speed of more than 400 kilometers per hour really cannot be used as an aircraft engine, but it can be used as a pure electric car.

He also had a whim, if he couldn't do it himself, he would build a awesome pure electric car, and then take the opportunity to establish a pure electric engine laboratory.

With such a laboratory, then he can unite more scientific researchers to promote the progress of this industry.

Of course, that's not the main purpose.

The main purpose is to persuade the leaders above, or to attract the military to help.

If there are more top scientific researchers, it is not the military.

Therefore, a few months ago, Zhou Jimin tried to find a way to transform the existing engine technology.

It took a month in the real world and five months in the small space world to complete the transformation, mainly to reduce the miniaturization, reduce costs, etc., and at the same time, it also needs to fit the driving experience of the car.

Once he was done, he went on to assemble the engine directly on a car.

Pure electric drive vehicles, compared with traditional fuel vehicles, still have great advantages.

At present, Zhou Jimin has overcome some difficulties, the most important of which is the battery.

He had already developed a lithium-air battery 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 at that time.

But now it's different, it needs to be installed on the car, and there are great requirements for battery life, power, etc.

Therefore, the battery of a pure electric vehicle can make the car have a range of more than 1,200 kilometers in the state of the highway.

Even on city roads, the car can have a range of up to 1,000 kilometers.

Therefore, the endurance of this lithium-air battery is enough to beat all traditional fuel vehicles on the market.

Of course, in the 70s of the world, many places did not pay much attention to environmental protection issues.

The so-called ozone hole problem was only discovered in 1984, and nowadays, not many people know about the dangers of freon.

After all, human-synthesized chlorofluorocarbons (CFCs) have been widely used since the twenties and thirties.

It became

The refrigerant of refrigeration equipment and household refrigerator air conditioning in many places has become the foaming agent of various hard and soft foams in the plastic industry, the aerosol of medical, hairdressing and air freshening, the tobacco expansion agent of the tobacco industry, and the cleaning agent of electronic components.

Such widespread use has caused the problem of the ozone layer hole over Antarctica in a short period of time.

However, these circumstances are a matter of time.

What's more, even if it is not the advantage of zero emissions, just the absence of exhaust and noise are very friendly to Oasis New Town.

Why?

Because the whole Oasis New Town is bigger, 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 by pure electric vehicles, they can make a huge contribution to the protection of natural ecology alone.

Moreover, without fuel vehicles, the demand for oil in Oasis New City has been directly reduced by more than half.

You know, today's Oasis New Town, the oil consumption every quarter is a large number.

It is precisely because of these advantages that not long after Zhou Jimin took out this pure electric car, he gave Gu Haishan and them their attention.

"Professor Zhou, your car is very strange, it is almost noiseless, and it is still so fast, did you use any noise reduction technology?"

Gu Haishan asked with a surprised face, he didn't think that this car was using foreign technology, such as Rolls-Royce and other automobile technology.

There are no cars like Rolls-Royce in the mainland, and Zhou Jimin did not take out these foreign cars from the space.

"No, it's an electric car, it doesn't burn oil, it burns electricity."

"Electricity?"

Hearing this, Gu Haishan's two eyes suddenly widened as big as copper bells.

His expression was full of incredulity, and he exclaimed, "How is this possible?"

"Why can't it be?"

Zhou Jimin chuckled, he didn't explain more, but drove the other party directly to the training ground of the army, and found Wang Ping'an and Wang Changwu.

"Two Comrade Wang, I want to discuss something with you."

When the two heard this, they were curious and delighted, and hurriedly asked what was the matter.

"That's right, I haven't figured out an electric car, and I'm going to continue research and development to see if it's possible to build an aero engine with a pure electric engine."

Zhou Jimin didn't go into too much detail about the rest of the matter.

If you want to build such an engine, it is very difficult.

It's normal to have difficulties, so that's why we set up an experimental laboratory and then we all work together.

However, Wang Changwu said that lithium-air battery technology has been limited, and even if a pure electric engine engine is developed, it will be useless.

"Of course it's useful!" Zhou Jimin shook his head and said:

"Didn't I develop a super lithium-air battery before, and although I haven't found a replacement now, I'm not working on it.....

Hearing Zhou Jimin say that he wanted to build a space shuttle with a pure electric engine, and then drive this plane to the moon to find new elements and find alternatives, Wang Changwu and they were all silent for a while.

Gu Haishan felt that Zhou Jimin's dream was commendable and very great, but he didn't agree.

Because it's ridiculous.

Today's Oasis New City, aerospace engineering has almost come to a standstill.

Although satellites are launched into space every year, there is little progress.

The space station didn't go out because they still had too many problems to solve.

In a short period of time, it is almost impossible to catch up.

In fact, there is no space station in space now.

Previously, the Salyut No. 1 launched by the Northern Bear Country was already a tragedy.

And now, the Northern Bear Country is making persistent efforts

, and began to prepare a Mir space station, ready to be launched into space.

Through the name Mir, we can also know how painful the previous Salyut No. 1 dealt to the aerospace industry of the bear country.

[In view of the general environment,

Just some time ago, the Bald Eagle also launched a space station called Space Laboratory.

And in order to solve the problem of keeping the space station in touch with the ground at any time, the bald eagle plans to contact the astronauts on the space station through radio waves.

But radio waves can only travel in a straight line and cannot make turns.

However, Skylab orbits the Earth every 90 minutes, which means that it only has six minutes of contact with the ground signal station.

As a result, scientists simply did not have time to collect the required materials.

As a result, engineers have built eleven terrestrial signal stations in many parts of the world, but these stations can only be built on land, and large areas of the ocean still have no receivers.

There are many scientific researchers in the bald eagle, so when solving this problem, many solutions have been proposed.

However, on the side of Oasis New Town, it cannot be solved.

This is also the reason why Zeng Qingfeng and the others have been stagnant and have not made leaps and bounds.

Zhou Jimin did not intervene, but let them develop slowly, for two reasons, one is that there are not enough top scientists, and the other is that he himself is very busy.

There are too many projects, and although they are in full development, they are now stagnant.

This is undoubtedly a heavy blow to the whole small town, which is accustomed to moving fast all the time.

Because of this, Zhou Jimin will slow down like this and take his time.

After all, the small city at this time is developing too fast, but other aspects have not kept up in time.

Especially in education, many talent gaps are too great, which is not good.

So how did the bald eagle solve the receiver problem in the ocean zone?

At first, the engineers on Bald Eagle's side suggested that the receiver be installed on the ship.

It's just that the speed of the ship is too slow.

So, in the end, it was changed to the airplane.

Therefore, during the period of May 1973, we could frequently see many planes sailing continuously at high altitudes.

These aircraft maintain communication between the ground and the space station by using a two-meter-diameter radio receiver at the nose of the aircraft.

When the space station comes to the top of the aircraft, the operator adjusts the angle of the receiving disc to get the information from the space station.

However, the speed of the aircraft is definitely not able to catch up with the space station, so when the Skylab space station flies out of the range of an aircraft.

The Bald Eagle would send another plane to take over, so that eight planes would be needed for the Bald Eagle to maintain uninterrupted communication between the ground and the space station.

Zeng Qingfeng and the others have also thought of these methods at present, but they are useless and are vetoed by Zhou Jimin.

The latter does not mention any satellite communication links, because it involves more powerful artificial satellite space technology.

Such a satellite needs to be launched into a navigation orbit within a range of several thousand kilometers above the ground.

You know, the distance between the space station and the ground is four or five hundred kilometers.

However, artificial satellites that can communicate with the ground and space stations are located within a few thousand kilometers of the ground.

A proper dimensionality reduction strike.

Such awesome technology means that there is a need for more and more awesome top scientists, and many, many of these top talents, not one or two.

Aerospace engineering is the tens of thousands of top geniuses who have always been the first in the country in terms of morality, intelligence, physical fitness, aesthetics, and labor, and after slowly growing up, they have become top scientists, and then get together to complete them

The engineering of this undertaking.

As long as you do a ninety-nine points once, it is not qualified.

After all, whether it is the Jiuquan Satellite Launch Center or the Salyut No. 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 of them scientists are very difficult and difficult, but they still have not completed the work, Zhou Jimin, a professor at Peking University and a computer inventor, actually said that he wanted to build a pure electric space shuttle into space?

Gu Haishan admired this, but he didn't agree with it.

Wang Changwu and Wang Ping'an are the same, but they are very supportive of Zhou Jimin's approach.

Of course, their support is useless, and the leaders of the troops must agree to it.

Next, Zhou Jimin took Wang Ping'an and the two to experience what a pure electric system car is.

I also know its acceleration, maximum speed, cruising range, and so on.

"By the way, Professor Zhou, what if this car runs out of power? How do I charge it? Is it fast to charge?"

"That's a very good question."

Zhou Jimin said with great appreciation:

"Regarding the issue of charging, I think so, directly in the community, units, gas stations and other places to build charging piles."

"Of course, this cost may be a bit expensive, but it doesn't matter, as long as you build a factory, the cost will always come down."

"The charging speed of the charging pile can be in two modes, one is the normal speed, and if it is fully charged, it will take about three to five hours.......

In fact, with this pure electric car, there is no need to charge it for so long.

As long as there is a 10% battery, it can support the car owner to return home or work, and then directly choose the normal charging speed again.

"There's another pattern, what's it?"
