The test run of Jinwu-1 is not over yet, and 66 consecutive tests will be carried out next.
In the test on March 5, the phenomenon of light radiation mark at the end of the laser electric pipeline appeared, as well as minor problems in dd injection, neutron crushing, fusion energy release, and helium ash discharge, as well as the time required to stop each link.
adjustment.
After reading the trial operation report, Zhang Huaide suggested to Fei Anming and Liu Jingguan:
"I have an idea. We can install a magnetic fluid motor on the helium ash discharge pipe, so that the thermal energy utilization efficiency of the helium ash will be improved again."
"Magnetic fluid motor?" Liu Jingguan pondered.
The so-called magnetic fluid motor is also called a plasma-conducting motor. Scholars in the field of nuclear power or electricity all know about this kind of thing.
However, the thermal energy utilization efficiency of the magnetic fluid motor is very low, only about 10%. Even if Galaxy Technology's unique normal temperature conductor coil is used, the electrical efficiency is estimated to be about 30%.
"Waid's idea is very good. I think we can give it a try. We can try it on the prototype." Fei Anming said first.
Liu Jingguan also nodded: "In the previous 863 plan of the Academy of Sciences, there was a magnetic fluid motor project. I remember that Academician Yan was studying this aspect."
"It seems that this project was canceled later, but the Academy of Sciences seems to have some research results on magnetic fluid thrusters. Last time, they also purchased a batch of room-temperature conductors from neutron star materials." Fei Anming was somewhat familiar with the inside story.
Zhang Huaide continued: "The reason why I suggest adding a magnetic fluid motor is because although the efficiency of the magnetic fluid motor is not as high as that of the steam turbine, the magnetic fluid motor has a very good advantage."
"You mean not to interfere with the steam turbine, right?" Liu Jingguan said with a smile.
Zhang Huaide didn't give in. "That's right, magnetic fluid motors and steam turbine motors can run together, and the interference between the two is very small."
"Although the electrical efficiency of steam turbines can theoretically reach 45%, in current practical applications, it is generally around 40%. If the condition of the turbine is not good, it may even drop to around 30-35%." Fei Anming paused.
, and continued:
"If a magnetically permeable fluid motor can be added, the overall thermal energy utilization rate will be 40%30% = 70%, a thermal energy utilization rate of 70%. This combined electrical system is more powerful than our laser electrical system."
"Haha, it's too idealistic. I estimate that the heat utilization rate can reach 65%, which would be amazing." Liu Jingguan said with a smile.
Zhang Huaide also laughed loudly: "Haha, we still have to have ideals. Maybe we can realize it as soon as we work hard."
"Li Xiang is having a headache recently about room temperature conductors, so you should stop talking about him all day long." Liu Jingguan joked.
Together, the three of them decided to use the prototype machine to try magnetic fluid electricity. As for the magnetic fluid motor, it was not difficult for them. The normal temperature conductor is available at the Qinling X-ray base next door. Other parts can be ordered directly from relevant manufacturers.
.
Speaking of the Qinling X-ray Base, they are also cooperating with the relevant work of the Plasma Research Institute, because a large part of Jinwu-1's future power will be supplied to the Qinling X-ray Base.
Although iron-silver room temperature conductors have been improved for so long, the service life has been increased to about 142,000 hours, which is equivalent to about 15 years.
However, the high energy consumption problem of iron-silver room temperature conductors is still difficult to improve. The current production cost of 1 ton is 32.7 million Mars coins, of which the electricity cost is about 31 million Mars coins, accounting for about 95% of the total cost.
If Jinwu-1 can supply cheap electric energy on a large scale, the current electric energy at the Qinling X-ray Base is specially supplied by the Galaxy Consortium, and the electricity price is o.18 Mars coins per kilowatt-hour.
Jinwu-1’s electric energy can lower the electricity price by 1o times and still be profitable, assuming that the electricity price is o.o18 Mars coins per kilowatt-hour.
The production cost of 1 ton of iron-silver room-temperature conductors will drop to: electricity cost 3.1 million yuan and other costs 1.7 million yuan = total cost 4.8 million yuan.
1 ton is 4.8 million, and 1 kilogram is 4.8 million Mars coins.
This is still a prerequisite for the electricity price to drop by 10 times. However, if the profit point of the electricity produced by the neutron squeezing method is lowered, the price can be reduced by 5o times and supplied to the Qinling X-ray Base.
Just think about it and you will know how low the cost has dropped. In addition, the cost of raw materials such as iron and silver will also drop because the era of space mining is coming.
This is an important reason why Neutron Star Materials Company decided to fully support the Golden Crow Project. Cheap electricity represents cheap production costs to a certain extent.
In less than a week, Liu Jingguan and others built a magnetic fluid motor.
After connecting to the helium ash discharge pipe of the first prototype, Liu Jingguan hurriedly started testing.
Although the first neutron press was very crude, it can also do what the Jinwu-1 neutron press reactor can do.
"The test begins." Liu Jingguan ordered the staff.
10 grams of dd nuclear fuel is injected, it is still compressed, fusion releases energy, and helium ash is discharged.
The helium ash discharge port is opened, and the high-temperature and high-pressure helium plasma rushes toward the vacuum pipe quickly.
"Magnetic Fluid Motor Electricity."
Not only does the magnetic fluid motor rapidly turn on, but the cooling water in the vacuum pipe is also rapidly heated and steamed.
In fact, helium plasma contains a lot of energy, which is at least equivalent to about 1o to 12% of the total energy released by the dd nuclear fusion reaction.
According to previous calculations by Liu Jingguan and others, the energy of the dd nuclear fusion reaction will be divided into four parts: light radiation 56%, thermal energy 27%, helium plasma 1o~12%, and other unusable parts 5~7%.
Originally, this helium plasma was an unusable part, but now using magnetic fluid motors, Liu Jingguan and the others have reused this part of the energy.
Liu Jing watched the real-time monitoring data on the holographic computer and calculated it. After a while, he came up with a rough figure. The electrical efficiency of the magnetic fluid was around 28-33%.
He is quite satisfied with this data.
Fei Anming opened the door of the control room and walked in. He saw Liu Jingguan who was deep in thought: "What are you thinking about?"
Liu Jingguan was stunned: "Oh? Nothing, it's just the efficiency of the magnetic fluid motor."
"What's the efficiency?"
"It's similar to what we expected, fluctuating around 28-33%."
"What is the steam temperature and pressure?"
"It's similar to what we tested before, there is no obvious change." Liu Jingguan replied.
"It seems that the magnetic fluid motor can be added." Fei Anming said after seeing the results.
"Not only that, I think the 27% direct heat energy should also be fully utilized." Liu Jingguan expressed his thoughts.
"You mean to use this direct heat to conduct magnetic fluid electricity?" Fei Anming pondered this proposal. After thinking for a while, he said:
"If you want to use direct heat to conduct magnetohydroelectricity, you must enlarge the outer solid vacuum chamber, then add metallic sodium, and use the metallic sodium to form a high-temperature and high-pressure sodium plasma. Will this affect the laser electrical system?
"
"We will conduct simulations first, and then use the prototype to test several more times. If feasible, we will use it on Jinwu-1." Liu Jingguan said.
