As he spoke, Wang Guanghai asked a key question:

"Old Ma, how much electricity does it cost you to project a kilogram of material to 94 kilometers now?"

Academician Ma touched his chin:

"Projected in the air, our capsule weighs about 34 tons and consumes 130~1.35 million kilowatt-hours of electrical energy, and 1 kilogram consumes almost 40 kilowatt-hours."

"If you have a vacuum pipeline of 60 kilometers, the capsule is estimated to be projected to more than 200 kilometers at once, assuming that half of the capsule is fuel and dead weight, that is, 1 kilogram of material consumes about 100 kilowatt-hours of electricity." Wang Guanghai calculated.

"The current electricity price is 5 cents per kilowatt hour, which is equivalent to about 50 yuan for 1 kilogram." Li Zhongting interjected.

Academician Ma shook his head and explained:

"You forgot to calculate the maintenance power of the vacuum pipes, and the cost sharing of the mass projectors."

"Even if it is the cost of 100 yuan of electricity for 1 kilogram, it is very cost-effective, and the cost sharing of the mass projector, if there are more launches, the cost will naturally be shared." Li Zhongting is very satisfied with this cost.

In fact, if you compare the current launch costs of various countries, you can see the gap.

NASA's space shuttle has a low-Earth orbit carrying capacity of 22.7 tons, and the launch cost per kilogram is 19,824 US dollars, and the cost of each launch is as high as 450 million US dollars.

However, on July 21, 2011, after the last mission of the "Atlantis", the space shuttle was officially decommissioned.

The latest model of the Ariane V rocket has reached 21 tons of low-earth orbit payload, and the launch cost per kilogram is 10,313 US dollars, and the cost of each launch of this type of rocket is at least 165 million US dollars.

The Soyuz-FG/Fregate launch vehicle has a low-Earth orbit carrying capacity of 6.9 tons, costs $7,246 per kilogram, and costs $50 million per launch.

The H-2B rocket used by the Solar Aerospace Exploration Agency has a payload of 19 tons, a transportation cost of 7,104 US dollars per kilogram, and the cost of each launch of this type of rocket is 135 million US dollars.

In addition, public information shows that before the new generation of launch vehicles such as Fat 5 was put into service, the Chang-3B rocket was the rocket with the largest carrying capacity in Dongtang's low earth orbit, with a payload of 12 tons.

The Chang-3B is the main force of Dongtang's launch of large communication satellites, and it is also the only rocket to launch the 3.5-ton Chang'e-3 and Chang'e-4 soft-landing lunar probes into lunar orbit.

The cost of transportation per kilogram is 5,833 US dollars, and the cost per launch is 70 million US dollars.

Tianzhu's largest launch vehicle (I don't know what it is called) is known as one of the four heavy rockets currently in service in the world.

However, the low-earth orbit carrying capacity of this type of rocket is far behind that of Dongtang's Chang-3B, which is only 3.8 tons, and the transportation cost per kilogram is 3,947 US dollars, and the cost of each launch of this type of rocket is 15 million US dollars.

Does it feel very cheap, the problem is that this launch vehicle can only be digested internally by the Tianzhu people.

Because others dare not use it, with the urine of the third brother, the reliability of this launch vehicle is a big question mark, not to mention the launch failure, if you accidentally send the satellite to the International Space Station, it will be funny.

Don't think that this kind of thing is impossible, after all, there is nothing impossible with the magical third brother, they are ruthless, and they can even do their own planes, so I ask you if you are afraid.

The rocket currently considered to be the least expensive to launch is the Falcon 9 rocket of SpaceX.

The Falcon 9 rocket has a low-Earth orbit (LEO) capacity of 22.8 tons, a geosynchronous transfer orbit (8.3 tons) and a launch capacity of 4.02 tons to Mars.

In the early days, the cost of each launch of this type of rocket was 62 million US dollars, and after the first stage of the rocket can be recycled and reused, the cost per launch is about 44 million US dollars.

The cost of transportation for launch into low-earth orbit is only $1,930 per kilogram; The cost of transportation for launch into geosynchronous transfer orbit is $5,300 per kilogram.

Assuming that the overall cost of the mass projection system is 300 billion Chinese yuan, and the cost of projecting 15,000 tons of material into outer space in a year is 20,000 Chinese yuan per kilogram.

If it is two years, it is 10,000 Chinese dollars per kilogram, three years is 6,666 Chinese dollars per kilogram, four years is 5,000 Chinese dollars per kilogram, and five years is 2,500 Chinese dollars per kilogram.

In other words, the cost of the mass projector will become lower and lower over time, and even if the maintenance fee is added at that time, it will become very cost-effective.

What's more, this mass projection system is estimated to cost less than 300 billion Chinese dollars.

After all, the most difficult vacuum pipes, which are completed using magnetic vacuum films, should not be too costly.

In the dead of night, the four of them went back to rest unsatisfied.

January 6, 2019.

Zhao Hongxing, Li Zhongting, and Wang Guanghai got up early in the morning to wash, and then ate breakfast at the guest house.

took the people of the space bureau and went to the 2017 building of Galaxy Technology.

Although the north wind was howling outside, the winter in the south was hot in the hearts of Zhao Hongxing and others.

Under the warm sunshine, they came to the unpretentious 2017 building.

Academician Ma also arrived, waiting for Zhao Hongxing and their arrival at the door.

"Old horse, it's early! Have you eaten it?" Li Zhongting greeted with a smile.

"Eat, come with me!"

Academician Ma led the group into the large conference room.

In the large conference room, there was no one there.

Most of these people are people from the Galaxy Science and Technology Research Institute, including the Materials Research Institute, the Battery Research Institute, the Electromagnetic Catapult Research Institute, the Vacuum Engineering Research Institute, the Atmospheric Motion Research Institute, the Airship Research Institute, the Astrophysics Research Institute, the Outer Space Research Institute, the Space Engineering Research Institute, and so on.

All the research institutes involved in the construction of the mass projection system this time were present to attend the meeting.

In addition, Galaxy Group, which is responsible for building the supercomputing center and supplying raw materials, sent several representatives to observe.

"There are so many research institutes of Galaxy Technology!" Li Zhongting looked at the signs on the tables of a large group of researchers or engineers, all kinds of research institutes had them.

"Not much, just more than two hundred!" Academician Ma also has a general understanding of the research institute of Galaxy Technology.

After all, he often has to deal with the management committee of the institute, and he knows more or less.

"More than two hundred? Not much?" Li Zhongting couldn't help complaining in his heart.

The research institutes of the Dongtang Aerospace System are those large-scale scientific research and production complexes, including the Dongtang Launch Vehicle Technology Research Institute, the Aerospace Power Technology Research Institute, the Dongtang Space Technology Research Institute, the Aerospace Propulsion Technology Research Institute, the Shu Provincial Aerospace Technology Research Institute, the Shanghai Aerospace Technology Research Institute, the Dongtang Aerospace Electronic Technology Research Institute, the Dongtang Aerospace Aerodynamic Technology Research Institute, and so on.

There are also large research institutes comparable to their research institutes in Galaxy Technology, such as the Materials Research Institute, the Semiconductor Research Institute, the Software Research Institute, and so on.

After receiving part of the power of the Rockefeller consortium, plus the semiconductor power of Dongdao, the scientific research strength of Sanxin Group and Sydney Company, the scientific research strength of Galaxy Technology can be said to be unprecedentedly strong.

Before the meeting began, Academician Ma took Zhao Hongxing, Li Zhongting, and Wang Guanghai to get to know the researchers of Galaxy Technology.

"This is Mr. Li Xiang, the head of the Materials Research Institute." Academician Ma introduced Zhao Hongxing and others.

The three of them also hurriedly greeted each other, but Li Xiang seemed lukewarm, and Zhao Hongxing and the three of them were not surprised, and there were always some strange people in those scientific researchers.

Especially the researchers in enterprises like Galaxy Technology, they speak by strength, unlike the unit where they can boil qualifications and leave favors.

And this Li Xiang in front of him, at most thirty years old, is already the head of a large research institute, and it is impossible without two brushes.

Walking down in a circle, Li Zhongting and Wang Guanghai also saw that Galaxy Technology is full of talents, as well as young and energetic, there are very few researchers over 50 years old, except for a few external bulls like Academician Ma, most of the researchers are about 30 or 40 years old.
