Chapter 399 Magnetic Fluids and Costs
The trial run test of Jinwu-[-] is not over yet, and successive tests will be carried out next.

In the test on March 3th, the optical radiation at the end of the laser power generation pipeline exceeded the standard, as well as minor problems in the links of DD injection, neutron squeeze, fusion energy release, and helium ash discharge, and the time between each link needs to be kept. adjustment.

After Zhang Huaide read the test run report this time, he suggested to Fei Anming and Liu Jingguan:
"I have an idea that we can install a superconducting magnetic fluid generator on the helium ash discharge pipe, so that the heat utilization efficiency of helium ash will be improved again."

"Superconducting magnetic fluid generator?" Liu Jingguan pondered.

The so-called superconducting magnetic fluid generator, also known as superconducting plasma generator, is known to scholars in the field of nuclear power or power generation.

However, the thermal energy utilization efficiency of magnetic fluid generators is very low, only about 20%, and very few can achieve this efficiency.

Using the unique room temperature superconductor coil of Yinhe Technology, the power generation efficiency is estimated to be increased to about 50%.

"Huide's idea is very good, I think we can try it, we can try it on the prototype machine." Fei Anming said first.

Liu Jingguan also nodded: "In the 863 plan of the Academy of Sciences, there was originally this magnetic fluid generator project. I remember that Academician Yan was researching this aspect."

"It seems that this project was canceled later, but the Academy of Sciences seems to have some research results on the magnetic fluid thruster. Last time they purchased a batch of room temperature superconductors from neutron star materials." Fei Anming has a better understanding of the inside story.

Zhang Huaide continued: "The reason why I suggest adding a superconducting magnetic fluid generator is that although the efficiency of the magnetic fluid generator is not as high as that of the steam turbine, the magnetic fluid generator has a very good advantage."

"You mean not to interfere with the steam turbine power generation!" Liu Jingguan said with a smile.

Zhang Huaide didn't hold back anymore: "That's right, the magnetic fluid generator and the steam turbine generator can operate together, and the mutual interference between the two is very small."

"Although the power generation efficiency of a steam turbine can reach 45% in theory, it is generally around 40% in practical applications at present. If the machine condition is not good, it will even drop to around 30-35%." Fei Anming paused , and continued:
"If a superconducting magnetic fluid generator can be added, then the overall thermal energy utilization rate will be 40% + 50% = 90%, 90% thermal energy utilization rate, this combined power generation system is more powerful than our laser power generation system."

"Haha, it's too idealistic. I estimate that the heat utilization rate can reach 80%, which is very remarkable." Liu Jingguan said with a smile.

Zhang Huaide also laughed loudly: "Haha, we still have to have ideals, maybe we can realize them with hard work."

"Li Xiang is having a headache about room-temperature superconductors recently, so stop talking about him all day." Liu Jingguan teased.

Together, the three decided to use the prototype to try superconducting magnetic fluid power generation. As for the magnetic fluid generator, it is not difficult for them. The Qinling X-ray Base next to the room temperature superconductor has it, and other parts can be ordered directly from the relevant manufacturers. OK.

Speaking of the Qinling X-ray Base, they are also cooperating with the Plasma Research Institute, because a large part of Jinwu-[-]'s future power generation will be supplied to the Qinling X-ray Base.

Although the iron-silver room-temperature superconductor has been improved for so long, the service life has been increased to about 14.2 hours, which is equivalent to about 15 years.

However, the high energy consumption of iron-silver room-temperature superconductors is still difficult to improve. The current production cost of 1 ton is 3270 million Martian coins, of which the electricity cost is about 3100 million Martian coins, accounting for about 95% of the total cost.

If Jinwu-0.18 can supply cheap electricity on a large scale, the current electricity of the Qinling X-ray Base is specially provided by the Yinhe Consortium, and the electricity price is [-] Martian coins per kilowatt-hour.

The power of Jinwu-10 can reduce the electricity price by 0.018 times and still be profitable, assuming that the electricity price is [-] Martian coins per kWh.

The production cost of 1 ton of iron-silver room-temperature superconductor will be reduced to: electricity cost 310 million + other costs 170 million = total cost 480 million.

1 ton is 480 million, and 1 kilogram is 4800 Martian coins.

This is the premise that the price of electricity will drop by 10 times, but if the profit point of the electricity produced by the neutron crushing method is lowered, the price can be reduced by 50 times and supplied to the Qinling X-ray base.

If you think about it, 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 decided to fully support the Jinwu project. Cheap electricity means cheap production costs to a certain extent.

In less than a week, Liu Jingguan and others built a superconducting magnetic fluid motor.

After connecting with the helium ash discharge pipe of the first prototype, Liu Jingguan hurriedly started testing.

Although the first neutron squeezer was very simple, what the neutron squeeze reactor of Jinwu No. [-] can do, it can also do it.

"The test begins." Liu Jingguan instructed the staff.

10 grams of DD nuclear fuel is injected, still compressing, releasing energy through fusion, and expelling helium ash.

The helium ash outlet is opened, and the high-temperature and high-pressure helium plasma rushes toward the vacuum pipeline quickly.

"Superconducting magnetohydrogen generators generate electricity."

Not only the superconducting magnetic fluid generator is generating electricity rapidly, but the cooling water in the vacuum pipeline is also rapidly heated and evaporated.

In fact, the energy contained in the helium plasma is quite a lot, at least equivalent to about 10-12% of the total energy released by the DD nuclear fusion reaction.

按照之前刘静观他们的测算，DD核聚变反应的能量将被分割为四个部分：光辐射56%、热能27%、氦等离子体10～12%、其他无法利用部分5～7%。

Originally, this helium plasma was an unusable part, but now with the superconducting magnetic fluid generator, Liu Jingguan and the others reused this part of the energy.

Liu Jing looked at the real-time monitoring data on the holographic computer and calculated. After a while, he came up with an approximate data. The power generation efficiency of superconducting magnetic fluid is about 38-45%.

For this data, he is quite satisfied.

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?"

Liu Jingguan was taken aback: "Oh? Nothing, just the efficiency of the superconducting magnetic fluid generator."

"What is the efficiency?"

"It's about the same as we expected, fluctuating around 38-44%."

"What is the steam temperature and pressure?"

"It's similar to what we tested before, and there is no obvious change." Liu Jingguan replied.

"It seems that the superconducting magnetic fluid generator can be added." Fei Anming said after seeing the result.

"Not only that, I think that about 27% of the direct heat energy should be fully utilized." Liu Jingguan said her thoughts.

"You mean to use these direct heat to generate magnetic fluid power?" Fei Anming thought about this proposal, and after thinking for a while, he said:
"If you want to use direct heat for magnetic fluid power generation, you must enlarge the outer solid vacuum chamber, then add metal sodium, and use metal sodium to form high-temperature and high-pressure sodium plasma. Will this affect the laser power generation system? "

"We first perform a supercomputing simulation, and then use the prototype to test it several times. If it is feasible, we will use it on Jinwu-[-]." Liu Jingguan said.

"Yes." Fei Anming nodded.
