After coming up, there was no rush to talk. Caroline and others took the truck back to the institute. Wang Qi wrapped Li Xiang in his cloak again, and the two of them rode away slowly on white horns in the crowd of melon-eating people.
It was already evening when he arrived at the institute, and there were no meetings. Li wanted to wash up, feed Bai Xiaojiao, and sit next to Wang Qi to watch him work.
Although the kingdom is small, there have been a lot of things going on recently. I have only been away for two nights, and there are documents rushing over.
It is mainly about funds, urban renewal in Heishui and Heishan, and some disaster-related documents.
The coal mine in Heishui is low-lying, and many mine caves are filled with water. There are not enough water pumps, and Fenggu Motors cannot meet the needs of more water pumps for a while. Moreover, Blackwater has not yet been connected to the entire territory's power grid, and coal mines need generators to pump water, which is even more difficult for motor plants.
Wang Qi recalled the recent report documents of Phoenix Power Grid. This month was a bit chaotic, and he might not be able to get rid of the black water in a short time.
… Let’s use steam power to drain water.
There should be some steam engines in the country that have not been transferred, and they can be used if they are modified.
Give instructions and take them back to Natasha.
Rest overnight and listen to the report after breakfast the next day.
Or in the form of illustrations and explanations:
"Now inside the crack, condensation water droplets from the rock mass gather downward, gradually cooling down the lower part. Yesterday we detected 1260 meters and saw the water surface, and measured the water temperature to be 75 degrees. Judging from the internal temperature of the rock mass investigated above, Before an earthquake, the water temperature can drop to about 65 degrees."
Or does Li want to ask: "What is the probability that the next earthquake will erupt steam again?"
"It lacks elements and cannot be calculated. Based on basic inferences and based on detection records as the average water fusion speed, the existing volume of water below may be dozens of times that of before. Even an asthenosphere with thousands of degrees would require very A large contact surface, and I don't think the asthenosphere would tear up a large enough surface area like a rock."
This is where the hope lies.
The rock layer above the asthenosphere for a long time will reach a temperature of hundreds of degrees or even higher. The tearing of the rock is not a mirror disconnection. Its surface area will be much larger than the two planes. In addition, the earthquake avalanche will also increase the additional contact surface. Therefore Only then can the gathering of groundwater be used to bring about the eruption of huge amounts of steam.
Now after a round of eruptions and rainfall, heat has actually been dissipated into the atmosphere and upper rock masses.
The next time there is an earthquake, the only cracks will be the higher-temperature rock layers below. As the temperature increases, the rocks will become softer and softer. The result of softness is that it is difficult for the water contact surface to suddenly increase, and there will be a gradual increase. the process of.
In other words, boiling water should be boiled underground for a few days until all the water is boiled before another large-scale eruption is possible.
"Is there any way to cool down the water?"
"Yes, magic devices can be used to speed up the cooling of water bodies. However, the depth limits the hoisting weight. The device cannot be made too large. The average working hours of small devices are more. Even if we start to do it now, it will not be able to do much. The effect it can have is very limited."
In the evening, Wang Qi had told Li Xiang everything he wanted to ask, so she continued to ask questions.
"Do you think the asthenosphere is actually being contacted down there?"
This issue is very important and related to the size of the floating island.
If the current trend continues, it is likely that each plate will have to be pulled out of the asthenosphere to take off, rather than cracking into stone slabs.
Caroline is relatively certain about this: "Yes, we have counted the total tonnage of rainfall in the two plates, estimated the total amount of steam erupted last time according to a certain proportion, and used this to calculate the calorific value to make sure that it is not possible to achieve the level of rock cracking at two or three hundred degrees. The scale requires at least one kilometer of rock formation and a temperature of over 400 degrees to achieve it."
“Why not a larger contact surface but a lower temperature?”
"The large contact surface is actually not conducive to steam eruption. The pressure formed by excessive heating of water in an instant will inevitably cause an explosion, which will not be as gentle as what we have experienced. This kind of long-term eruption will cause a lot of water to condense and flow back into the crack. If the base temperature is not enough, the backflow water will quickly suppress the eruption due to the heat exchange capacity of the rock formation."
Simply speaking, the concept of heat exchange is that the greater the temperature difference between the two ends of the thermal conductive material, the higher the heat exchange power. Therefore, when it comes to thermal conductivity, there must be a temperature label. Anyone who does not label the temperature is a rogue.
What Caroline means is that assuming the contact area remains unchanged, only rocks or asthenosphere with higher temperatures can achieve this sustained eruption effect.
If several times of the area is exposed to low temperature, a steam explosion should be formed first and then calm down shortly after the eruption.
"So there shouldn't be much time left before the tectonic plates really take flight?"
"That seems to be the case now, but we have never seen that scenario. We don't know what the criteria for real takeoff are. There may still be variables."
The small conference room was quiet for a while, and then Wang Qi spoke: "Thank you for your hard work. In the future, we will still follow the previous measurement method. Pay attention to safety and don't probe too deep. If it is necessary to ask Li Xiang or the captain of the guard to come over, just ask Xiu to write Write to me."
"Yes, Your Majesty."
The two of them went out, riding a bear and taking Natasha to the next station slowly.
On the way, Li Xiang asked, "What were you thinking about just now?"
“I wonder if there are enough resources.”
"ah?"
Wang Qi explained: "The high temperature zone cannot retain oil and gas resources. I was worried that the take-off part was not thick enough and lacked resource development. Judging from the numbers they calculated, the location you detected may only account for a small part of the depth of the fracture." Partly, such a thickness should be able to preserve a considerable layer of resources.”
Li Xiang didn't like talking about these things, so he changed the subject: "After we take off, everything below will turn into the sea."
Wang Qi shook his head: "It's not like that. I suspect that there will be a certain thickness of the atmosphere mainly composed of steam."
If the groundwater is now connected to the asthenosphere, when the plate takes off in the future, the core including the asthenosphere will be fully exposed, and the heat will definitely not be extinguished by a little seawater on the surface.
At that time, a high-pressure vapor layer may form close to the ground. The temperature will become lower as it goes up, gradually forming water vapor.
"Isn't it just like living on the clouds?" Li Xiang has also been on a plane. Two to three thousand meters is the height of cumulonimbus clouds, and he has seen them above the sea.
Wang Qi also thought of the sea of clouds he could see while climbing: "Maybe, I'm a little worried about oxygen."
"Oxygen?" Li Xiang didn't respond.
"The ocean, without the oxygen produced by the algae in the ocean, the height will increase by an unknown amount. Maybe there won't be enough oxygen, and we don't know how many people will die."
Li Xiang hugged his waist from behind: "Then there's nothing you can do."
Wang Qi put his hand on hers and sighed softly: "Yes, the changes are too drastic. The industry is not mature enough and the population is not enough. There is no time to make too many preparations."
Having said that, in fact, even when the industry matures and even the mature microelectronics industry is included, human power will appear very small in the face of such large-scale drastic changes.
This can be understood by simply calculating the tonnage. Assume that the depth of the crack at the edge of the plate in the dark land is four kilometers. If we take off with this thickness, the total weight is about 2.16e+14 tons. If we directly write "6", there will be 12 after it. Zero, the annual steel production of less than 100,000 tons is nothing compared to this order of magnitude, and the transformation that can be done is only equivalent to coating the surface with a film, and there is no way to fully coat the surface.
