Mass accelerators are necessary facilities for large-scale space development and are more practical in application than space elevators.

Yang Yi is also very aware of this, but he did not participate in related projects.

Due to the high escape velocity of the Earth and the aerodynamic heating problems caused by the dense atmosphere, it is impractical to launch spacecraft or materials directly with mass accelerators on the Earth at this stage.

The peak of re-entry aerodynamic heating of space shuttles and manned spacecraft is between 70 and 50 kilometers above sea level, where the atmosphere is much thinner than at sea level or even at the summit of Mount Everest.

Moreover, the re-entry speed of the space shuttle and manned spacecraft in this area has also been reduced a lot due to the previous rocket deorbiting braking and atmospheric drag in higher areas.

On Earth, the air density is relatively much higher because the mass accelerator launches the spacecraft at a higher exit altitude than Mount Everest.

And taking into account the loss of atmospheric drag and gravity, the speed will be much higher than that of the space shuttle and the return capsule of manned spacecraft.

This means that there is a lot more pneumatic heating, and the thermal protection technology required is much higher than the first two. This in itself drives up costs and brings serious safety risks.

Therefore, the real stage of the mass accelerator is on large natural satellites, dwarf planets, and large asteroids without dense atmosphere, and there is no need to worry about aerodynamic heating.

Therefore, Yang Yi's research in this area is placed after the space elevator, and the current related research topic is to establish a large-scale mass accelerator on the moon, referring to future science and technology, and the prepared lunar mass accelerator has two configurations, one is based on the principle of linear motors, similar to the design of electromagnetic catapults on aircraft carriers; The other is an enlarged version of the electromagnetic coil cannon, which can launch tens of thousands of tons of lunar minerals into a predetermined orbit every year, possibly the Earth-Moon Lagrange L1 point, which is captured and transported by a special spacecraft to the space station for refining and processing, and the slag is used as a shield for radiation and meteoroids.

With the mass accelerator and the launch of lunar resources, human beings can economically and quickly build giant space solar power stations and giant space cities, and realize space industrialization and colonization.

At this stage, it is not practical to deploy mass accelerators on Earth, and in the future, after the energy technology reaches a certain stage, it is possible to eliminate the space elevator, but in this century, this transitional technology is still needed.

The design of the United States is to arrange a series of mass accelerators in low-earth orbit, from the ground stage acceleration to escape orbit, the speed is relatively small and suitable for manned, but the control accuracy is a big problem, in addition, the energy is not cost-effective at this stage.

Even if the energy source is slightly richer now, it will not be rich after the start of the space program, otherwise Yang Yi would not have to promote nuclear energy technology.

This can form a considerable grudge with those oil tycoons in West Asia and North Africa.

……

Adventure,It's the standard treatment of a "protagonist",Most common "adventures" are "rebirth",After meeting with Ma Xiaoling not long ago,Yang Yi noticed the "fate" monster that had been entangled with the Ma clan for thousands of years,After investigation,Found the anomaly of this "monster"。

Perhaps, this is also a god, a god born from the worship of the ancestors, who manipulates the rhythm of fate of one person after another, but in this era, the power of this monster has declined significantly, and even because of several failed manipulations, it has led to a backlash.

And a "crisis of annihilation" planned by fate was eliminated before it began, trying to restore part of its strength with the threat of the extinction virus, but before it could be implemented, the immortal gene was popularized, and the broad-spectrum immunity in it made the virus in the fate plan useless.

It may cause some damage to pets or stray creatures in the city......

There are already a hundred and ten cases of "rebirth" manipulated by fate, but several of them have escaped from his control, resulting in a significant decline in his power.

For example, Su Can, who is now the third richest person in the world, chairman and president of Renren.com, was originally controlled by fate after the possibility of the next ten years, according to the plan of fate, this should have experienced the ups and downs of life, and he harvested his soul.

But I didn't expect that after the big rise, it would be Dapeng that rose with the wind one day and soared up to 90,000 miles! It has never been left behind, and it can be said that all his investments have been lost.

Zhang Ge, the chairman of Jinhu Group, who used to be the first on the list of the richest people in China, has gone through some ups and downs, this is a more optimistic figure, and the investment is also greater; What a glorious scene Jinhu Group was back then, Aida Electronics was already an internationally renowned consumer electronics brand ten years ago.

has even made achievements in the field of chips, but if it is caught, it will almost disappear once it is caught.

After the ups and downs, it is likely to collapse, not to mention from billionaires to billionaires, but Zhang Ge can start from scratch again, starting from the paper industry, after more than ten years of hard work and afforestation, now in India, Pakistan, Bangladesh and other places of paper mills everywhere, but also once again into the top ten ranks of China's richest list, fate has a plan to fail.

The former richest man in Shanghai, the pioneer of online games, the ups and downs of fate interference were not all successful, and its industry did not fall to the lowest point before it was acquired by the Star Group, which was killed halfway.

It's not all about nothing, it's just that when this world of great controversy is coming, how can it be so easy for fate to grasp which outstanding souls want to grasp first?

This kind of character is all lucky, and it is even more common for evil to turn good and good fortune into trouble, and the difficulties caused by fate are nothing more than small obstacles on the road to their success.

Thirty or fifty years ago, the means of fate could still sustain one or two harvests, but now, in the past twenty years, hundreds of percent of the investment is actually only half of the harvest.

Fate not only figured out "rebirth", but also figured out the routine of "crossing", but among the people he selected, only half of them really allowed him to achieve what he wanted.

There are two people, Yi Xiaochuan and Gao Yao, who have experienced the reincarnation of fate manipulation, Yi Xiaochuan in "Myth".

Yi Xiaochun, a playboy, aims to find a hundred girlfriends; Gao Yao, a cook, an ordinary person; After the two crossed over to the Qin Dynasty in the illusion, Yi Xiaochuan followed his goal, first teasing Lu Pheasant, causing Lu Pheasant to promise each other, but how could it be possible for a woman to end the goal, Yi Xiaochuan introduced the woman to a gangster Liu Bang he knew.

Later, he teased Lu Su and asked this woman, for the sake of Yi Xiaochuan, to give up the chance of being rescued, and finally contracted the plague and died; Of course, this didn't make her sad, and he went to tease Satsuki again.

In general, Yi Xiaochuan has not changed his original intention, and he has always been a scumbag growth history; On the contrary, it is Gao Yao, although he has the manipulation of fate in the illusion, but he still finally changed himself and became "Zhao Gao".

This also made fate only harvest Yi Xiaochuan's soul, and the input and output were basically the same.

The investigation got such a tragic history of fate, and Yang Yi didn't pay much attention to it, this is almost the same as those "old grandfathers" who send benefits everywhere without asking for anything in return, after countless years, they have absorbed countless human beliefs about "fate", and now they have fallen to the point where it is difficult to manipulate even a city and a place, which is really ridiculous!

However, Yang Yi will not risk his life, going to Xiangjiang to face this monster god, whether it is dangerous or not, for the current Yang Yi, it is not worth it.

Perhaps, Ma Xiaoling's coming to see Yang Yi was a temptation of fate, wanting Yang Yi to be aware of his existence; Perhaps, the information investigated by Shen Luoyan may be fake, or it may be a trap of fate.

The Son of Heaven sits in the Ming Hall; Naturally, I won't go to the risk in person, otherwise who would I have worked so hard to build such a big foundation?

Nowadays, Yang Yi has not interfered much in the management of group affairs, Andy's ability is very strong, and the story between the two is not a domestic Mary Sue Cinderella president, because Andy is definitely not an ordinary assistant level, let another girl who can warm the bed be directly promoted to the CEO of a trillion-dollar market value company, this may be a joke?

But Andy is different, first of all, although the relationship between the two is trustworthy enough, Andy's ability has reached the standard of Yang Yi's needs, and there are many girls who have an intimate relationship with Yang Yi, but in the end, only Andy can help Yang Yi control the Star Group.

Yang Yi is now almost not involved in the company's decision-making, basically in the group is now equivalent to the CTO, there is a star group is providing her with a steady stream of funds, so that she can take time to solve technical problems, and Andy knows how to make more money with her technology, and the snowball is getting bigger and bigger.

This kind of top-level management ability and investment vision have already surpassed others a lot, young and amazingly talented, and Yang Yi's three views are basically the same, can bring the Star Group to the road Yang Yi wants, and now the outside world is sighing, being so reasonable, why did Tan Zongming have no eyes at that time?

This is the sour thing that some people will say when many business people meet, Tan Zongming is now taking advantage of the rise of the Star Group, and his net worth has increased several times, but there are many people who are interested in him.

Because, I only see that he is an OEM company, or also known as a "sweatshop", I feel that there is no technical content and threshold, and he can still do it if he is a different person, as long as he can get orders from Star Group and Apple.

Although Apple has now distributed most of the orders to other manufacturers, with the orders of the Star Group, it is enough for Tan Zongming to eat.

Hon Hai Group now boasts more than 2 million industrial workers at the peak of its factories in China, and this radiating industrial chain can make employment in any city no longer a problem.

Now Tan Zongming no longer thinks about his own brand, he only thinks about doing a good job in the OEM project wholeheartedly, and outsiders only see his scenery, but they don't think about his hard work.

It is not easy to maintain a relationship, especially with the development of Star Group, more and more requests are made, although there are more and more orders, it can only be said that it is painful and happy.

Even if Star Group now wants to participate in the salary system and the working environment of Hon Hai, Tan Zongming can only do it one by one.

"Mr. An, Mr. Tan from Hon Hai wants to visit you at 3 p.m."

Andy has been busy all morning, but there are seven or eight meetings of all sizes, her work style is vigorous and resolute, she just scolded a product manager in the meeting, and the little secretary Qi Yun was a little nervous at this time, but she still had to report the matter, otherwise she would have to be trained.

If it weren't for the benefits and salary conditions of the Star Group, which were really good, Qi Yun would have resigned even if he thought about me.

Although with her education and ability, she can find a good job by the way, but it is not easy to encounter such a big platform as the starry sky.

Nowadays, not only do you have to compete for jobs with your peers, but you also have to compete for jobs with those old people who have retired before; If you change jobs, your monthly high-end cosmetics, the latest technology products, and regular outings may be completely eliminated or drastically reduced.

Andy thought as he walked, and suddenly said, "Let him come over at 3.30 p.m.!" ”

Thinking that Yang Yi said last time that he would arrange a batch of intelligent AI robots, that is, the "Xiaoxing" series to be tested in the factory, there are a total of twenty units, of which ten have now been tested in their own factories, and the remaining ten are ready to be tested by various partners.

Starry Sky's OEM is not exclusive, but Tan Zongming's Hon Hai is the largest one to take orders.

"Xiaoyun, you go and inform Xu Wei and ask her to arrange the testers of the "Xiaoxing" series. ”

……

Kolkata, a humble apartment building in the city, is undergoing an unknown change.

The Mage Tower is the most important base for a mage, and with the Mage Tower, a mage can cast spells without any scruples, and it is very easy for a mage with a mage tower to challenge the level.

After many tribulations, Ivan traveled from Bangladesh to India, crossed the Ganges, and after a few spells, he was able to obtain enough money, but he also encountered an unprecedented crisis.

Unlike Huaguo, basically as long as you stay at home, most dangers will not find you, Ivan has studied knowledge in Huaguo for so long, and he has not encountered any crisis.

The only thing he encountered was the crisis that forced him to flee to India, in fact, he was able to escape at that time because Qiao Niannu kept his hand, at that time, Qiao Niannu was not for the purpose of killing, but just for arrest, which also gave Ivan a chance to escape.

However, in the face of Indians, especially a rich man who looks like a Chinese country, and does not carry bodyguards, that is, children hold gold in the downtown area.

When he first came to India, because of the long-distance travel, the reserve water in Ivan's space was not much, and he thought that he would pick up a large amount of tap water in the hotel like Hua Guo.

At that time, he didn't care, he drank a few sips because he was thirsty.
