The test trial test of Jinwu No. 1 is not over, and the next tests will be carried out one after another.

In the test on March 5, there were excessive optical radiation at the end of the laser power generation pipeline, as well as minor problems in DD injection, neutron pressing, fusion energy release, and helium ash discharge, as well as the time between each link that needed to be constantly adjusted.

After reading the trial operation report, Zhang Huaide suggested to Fei Anming and Liu Jingguan:

"I had an idea that we could install a superconducting magnetofluid generator on top of the helium ash discharge pipe, so that the heat efficiency of helium ash would be improved again."

"Superconducting magnetofluid generators?" Liu Jingguan pondered.

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

However, the thermal energy utilization efficiency of the magnetofluid generator is very low, only about 10%, and even if the unique superconductor coil of Galaxy Technology is used, the power generation efficiency is estimated to be about 30%.

"Wilder's idea is very good, I think we can give it a try, we can try it on the prototype." Fei Anming spoke first.

Liu Jingguan also nodded: "In the 863 plan of the Academy of Sciences before, there was originally this ferrofluid generator project, and 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 magnetofluid thrusters, and last time they also purchased a batch of room temperature superconductors from neutron star materials." Fei Anming knows more or less about the inside story.

Zhang continued: "The reason why I propose to add superconducting ferrofluid generators is because although the ferrofluid generator is not as efficient as the steam turbine, the ferrofluid generator has a very good advantage. ”

"You mean don't interfere with the steam turbine power generation!" Liu Jingguan said with a smile.

Zhang Huaide didn't sell it anymore: "That's right, the magnetofluid generator and the steam turbine generator can run together, and the two interfere with each other very little." ”

"Although the power generation efficiency of the steam turbine can reach 45% theoretically, it is generally about 40% in practical application, and if the engine condition is not good, it will even drop to about 30~35%." Fairemin paused, and continued:

"If a superconducting magnetofluid generator can be added, then the overall thermal energy utilization rate will be 40%+30%=70%, 70% thermal energy utilization, and this combined power generation system is more powerful than our laser power generation system."

"Haha, that's idealistic, I estimate that the heat utilization rate can reach 65% is very remarkable." Liu Jingguan said with a smile.

Zhang Huaide also laughed: "Haha, there is still an ideal, maybe we will achieve it as soon as we work hard." ”

"Li Xiang has been having a headache about room temperature superconductors recently, so don't talk about him all day long." Liu Jingguan teased.

The three of them decided to take the prototype to try superconducting magnetic fluid power generation, as for the magnetic fluid generator, it is not difficult for them, the room temperature superconductor is next door to the Qinling X-ray base, and other parts can be ordered directly from the 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 the future power generation of Jinwu No. 1 will be supplied to the Qinling X-ray base.

Although iron-silver room temperature superconductors have been improved over such a long time, the service life has been increased to about 142,000 hours, which is equivalent to about 15 years.

However, the high energy consumption of iron-silver superconductors at room temperature is still difficult to improve, and the current production cost of 1 ton is 32.7 million Martian coins, of which the electrical energy cost is about 31 million Martian coins, accounting for about 95% of the total cost.

If Jinwu-1 can supply cheap electricity on a large scale, the current power of the Qinling X-ray base is specially supplied by the Galaxy Foundation, and the electricity price is 0.18 Mars coins per kilowatt hour.

It would still be profitable for Jinwu 1 to reduce the price of electricity by a factor of 10, assuming the price of electricity is 0.018 Mars per kWh.

The production cost of 1 ton of iron-silver room temperature superconductor will be reduced to: electricity cost 3.1 million + other costs 1.7 million = total cost 4.8 million.

1 ton is 4.8 million, and 1 kilogram is 4800 Mars coins.

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

Think about how low the cost will be, and the cost of raw materials such as iron and silver will also fall, because the era of space mining is coming.

This is an important reason why Neutron Star Materials has decided to fully support the Golden Crow project, and cheap electricity represents cheap production costs to a certain extent.

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

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

Although the first neutron press was very rudimentary, what the neutron press reactor of Jinwu No. 1 could do, it could do.

"Test begins." Liu Jingguan instructed the staff.

10 grams of DD nuclear fuel is injected, and it is still compressed, fusion released, and helium ash is discharged.

The helium ash discharge port is opened, and the high-temperature and high-pressure helium plasma quickly rushes towards the vacuum pipeline.

"Superconducting magnetofluid generators generate electricity."

Not only are superconducting magnetofluid generators rapidly generating electricity, but the cooling water from the vacuum pipes is also rapidly heated and evaporated.

In fact, the energy contained in helium plasma is not a small amount, at least equivalent to about 10~12% of the total energy released by DD nuclear fusion reaction.

According to Liu Jingguan's previous calculations, the energy of the DD nuclear fusion reaction will be divided into four parts: optical radiation 56%, heat energy 27%, helium plasma 10~12%, and other unusable parts 5~7%.

Originally, this helium plasma was an unusable part, but now using a superconducting magnetofluid generator, Liu Jingguan and they reused this part of the energy.

Liu Jing watched the real-time monitoring data on the holographic computer and calculated it, and after a while, he came up with a rough data, and the power generation efficiency of superconducting magnetic fluid was about 28~33%.

He is quite satisfied with this data.

Fei Anming opened the door of the control room and walked in, and he saw Liu Jingguan who was pondering: "What are you thinking?"

Liu Jingguan was stunned: "Oh? Nothing, it's just a matter of the efficiency of superconducting magnetofluid generators. ”

"What's the efficiency?"

"It's about the same as we expected, fluctuating around 28~33%."

"What is the temperature and pressure of the steam?"

"It's pretty much the same as what we tested before, with no noticeable changes." Liu Jingguan replied.

"It looks like a superconducting magnetofluid generator could be joined." Fei Anming said after seeing the results.

"Not only that, but I think we should make full use of the 27% or so of direct heat." Liu Jingguan said what she thought.

"You mean to use this direct heat for ferrofluid power generation?" Fei Anming pondered over this proposal, and after thinking for a while, he spoke:

"If you want to use direct heat to generate ferrofluid electricity, you must enlarge the outer solid vacuum chamber, and then add sodium metal, and use sodium metal to form a high-temperature and high-pressure sodium plasma, will this affect the laser power generation system?"

"We start with superconductivity simulations, then test them with prototypes a few more times, and if feasible, we use them on Jinwu 1." Liu Jingguan said.

"Yes." Fei Anming nodded.
