The rise of nanometers

When Zhurong Class 002 arrives at Venus.

The time has arrived on January 5, 2020.

Cheng Ming's team knew that they could not waste time now, because their working time in Venus was about 24 months.

Nearly five months have passed since they arrived at Venus, leaving them only about 19 months.

Moreover, when working on an alien planet, the schedule cannot be too tight. One or two months of emergency time must be reserved for emergencies.

After Zhurong 002 arrived, Cheng Lin and Wang Yunhai began to place the manufactured functional modules into the floating city one by one through remote control.

After the wind power generation module is assembled on the floating city, it is connected to the previous carbon powder energy storage power generation module, and then the power distribution control module.

Because the wind in the atmosphere of Venus is too strong, the blades of wind turbines are specially designed, vertical and simple blades that can generate electricity in any direction.

The commonly used windmill blades on Blue Star are not suitable in the atmosphere of Venus.

In strong winds, rows of wind turbines are constantly rotating. They use non-contact magnetic bearings so that the wind turbines do not need to worry about mechanical wear.

"Captain, the power generation has stabilized. The current lowest power is 60,000 megawatts and the highest power is 136,000 megawatts." Wang Yunhai said while looking at the data.

"Sure enough, the wind energy on Venus is very abundant, so we started to make limited settings."

"receive."

Limit settings are to avoid problems. Limiting the power of power generation equipment can reduce production problems caused by power instability.

You should know that in many industrial production processes, power supply requirements are very strict. If fluctuations occur frequently, it may cause product problems.

Since the power generation of wind power modules fluctuates between 60,000 and 136,000 megawatts, usually only the low 60,000 megawatts can be taken, and even to ensure foolproofness, only 40,000 to 50,000 megawatts can be taken.

Of course, although a limited usage quota is adopted, this is only for wind power generation modules.

For this kind of waste electricity with unstable power generation, the federal government has long had a mature solution, which is carbon powder energy storage power generation technology.

The unstable part is used to generate electricity, intercepted and used to produce carbon powder, and then the carbon powder is used for secondary power generation.

Although about 23% of the electrical energy will be lost in this process, it is better than wasting it all.

Moreover, carbon powder energy storage power generation technology is very effective for peak load regulation and valley filling.

The floating city currently consists of five floating modules, suspended at an altitude of 47 kilometers, with a total buoyancy of about 32,000 tons.

Subtracting the current dead weight and equipment of about 6,700 tons, there is still about 25,300 tons of available buoyancy. In addition, if the height is lowered, this load-bearing capacity can continue to increase.

Currently, among the functional modules of the floating city, there is only one N30 manufacturing module. Its full power production is 5,000 megawatts and it can produce 1,200 tons of N30 fuel every day.

The remaining electrical energy can only be used for toner production.

Fortunately, in a few days, two striker-class spacecraft will arrive at Venus, and a toner processing module will be transported there.

At this stage, it is not that wind power is not enough, but that it is inexhaustible.

The toner storage space in the floating city is relatively limited. If the toner cannot be processed in time, the power generation will be wasted.

Therefore, we must find a way to solve this problem.

The aerospace department's solution is to create a sphere that can withstand high temperatures and pressures. In fact, it uses materials similar to those used to make vacuum chamber shells to manufacture such spheres.

This kind of sphere can store 500 tons of toner individually.

The sphere containing the toner will be thrown to the surface of Venus.

That's right, the carbon storage balls will be thrown to the surface of Venus instead of being stored in the floating city, wasting the precious buoyancy of the floating city.

This plan is to quickly transform the atmosphere of Venus and fix the carbon elements in the atmosphere on the ground.

This uses the energy of Venus' atmosphere to gradually reduce the concentration of Venus' atmosphere. As long as the concentration of Venus' atmosphere drops to about 20% of the current level, the construction of ground stations can begin.

In the atmosphere of Venus, the proportion of carbon dioxide is as high as 96.5%, so decomposing carbon dioxide has become the most ideal solution.

As for oxygen, another product of the decomposition of carbon dioxide, part of it will be used as industrial raw materials for floating cities, and part of it will be released back into the atmosphere.

The final part will be packed into similar spheres, solidified with an oxygen-fixing agent, and then dropped to the surface of Venus.

The storage life of these carbon storage balls and oxygen storage balls thrown to the surface of Venus is about 150 years.

As long as the Federation successfully establishes a permanent base on the surface of Venus during this period, it can use the reserves of these storage balls as industrial raw materials.

It is equivalent to a warehouse of refined semi-finished raw materials.

The Ministry of Aerospace has formulated a 30-year solidification plan for this purpose, and plans to reduce the gas content in Venus' atmosphere to 5 to 10% of the current level in the next 30 years.

This is a very long-term plan, but it is the most likely plan to transform Venus.

Supporting plans include the Venus Space Elevator Project and the Venus Dome Project.

Venus Space Elevator Project, this does not need to be explained in detail, because this is a replica of the Blue Star Space Elevator Project.

The Venus Dome Project is a super project among super projects. The Ministry of Aerospace plans to wrap the entire Venus with a dome.

According to the current material strength, the height of the dome is 3,500 meters above sea level, covering the entire surface of Venus, and at the same time, different areas are separated by walls.

The reason why it is necessary to fully cover and then separate different areas is to create an artificial protective layer, and also to limit the active volcanic eruptions of Venus to the surface and local areas.

According to the goals of the solidification plan, Venus’s atmosphere may be completely stripped off in the future, turning it into a bare planet.

These plans are very large and require a lot of time. They may require several generations of continuous transformation.

Compared with building large-scale structures in space, building giant structures on the surface of a planet is less likely to be observed by other galaxies.

Of course, the Venusian dome system was a gradual process.

At the beginning, construction can start from a small local area, such as the ground station of the space elevator, where a dome space can be built first.

A few days later.

Two striker-class spacecraft arrived and brought storage ball manufacturing modules. This module can also be used to manufacture vacuum chambers. However, the vacuum chamber requires other spare parts to create a floating module.

When the storage ball manufacturing module is assembled, the excess toner produced by the toner energy storage module will be stored in these storage balls.

Then throw it to the ground.

The storage ball weighing more than 500 tons was thrown from a height of 47 kilometers and slammed into the rock formations on the ground.

If you peel off the dense atmosphere, you will be able to see that underneath the floating city, there are large pits on the ground, with storage balls inside.

On an average day, six or seven storage balls are thrown to the surface.

In order to avoid hitting only one area, the floating city will adjust the floating area from time to time.

It's not obvious yet, but when the scale of carbon powder production expands in the future, it is estimated that this kind of storage ball will change the topography of Venus' surface.
