Huang Haojie saw the report sent by the management committee of the institute, saying that the Academy of Sciences wanted to buy a prototype for research.

After thinking about it for a while, since he had agreed to Dongtang to purchase two Jinwu No. 1, there was nothing to sell this prototype to them for research, so he approved this matter.

After reviewing some important documents, he went directly to the anthropomorphic bionic robot at the Keelung Secret Research Institute.

In fact, after Liu Jingguan proposed the neutron squeezing generator, Huang Haojie has also been conducting related research.

In one of the laboratories of the secret research institute, Huang Haojie, with the assistance of Zhong, is injecting DD solids (made by the submetallic hydrogen method) into a miniaturized neutron press reactor.

This small neutron press reactor is in the shape of a ball and about the size of a football ball.

Inside, the rugby-shaped condensed matter vacuum chamber is encased in a ring-shaped vacuum tube made of mixed gel material, and on the outside is a ring of superconducting coils, one-fifth of which is filled with metal sodium.

He turned on the holographic computer and pressed the reaction switch.

The working principle of a small neutron press reactor is exactly the same as that of a large one, both of which are injected with nuclear fuel, compressed, released energy, and discharged ash.

However, there is definitely no way to install steam turbines in small neutron press reactors, and there is no way to install even laser power generation pipelines.

The small machine in front of Huang Haojie uses a superconducting magnetic fluid power generation system, which directly uses optical radiation and direct heat to heat sodium metal to form sodium plasma power generation.

However, the DD nuclear fuel in this reactor is only 0.1 grams, which is also 100 milligrams.

Deuterium atoms account for 98% of the 100 mg DD solid nuclear fuel, and after the nuclear fusion reaction, it can theoretically produce about 8,500 kWh of energy, and the reaction moment is about 1,800 seconds, and the average power generation is about 4.72 kWh per second.

However, Huang Haojie's real-time monitoring data at this moment shows that the power generation is between 1.32~1.34 kWh per second, and the power generation is only equivalent to about 28% of the theoretical energy.

The reason why the energy conversion efficiency is very low is that the heat energy utilization rate is too low.

In order to reduce the weight of the nuclear fusion process of the minicomputer, only ferrofluid power generation systems can be used at present.

In the ferrofluid power generation system, 56% of the optical radiation energy needs to be converted into heat energy (optical radiation heats sodium metal), and the energy conversion efficiency in this process is about 80%, and after this round of conversion, it becomes 44.8% thermal energy.

44.8% of the heat energy is converted from light radiation, and 27% of the direct heat energy is added, and the total amount of heat energy that can be used is 71.8%.

The thermal energy utilization rate of the ferrofluid generator is about 40%, and about 28.72% of the converted electric energy is left, and the rest of the energy is wasted.

Huang Haojie looked at the hot small machine in front of him and became distressed, this small machine was heating up frantically due to these unusable heat.

If it weren't for the fact that the materials used were very strong, the high temperature of the fuselage of up to 742 degrees Celsius would have almost melted steel.

Large neutron press reactors can use steam turbines to use this heat, while small ones cannot be equipped with steam turbines.

The refrigeration equipment in the laboratory uses a large amount of electricity to cool down than the amount of electricity, even if it is installed in the mecha, it can be cooled by natural air to dissipate heat, and there are not a few electric energy that need to be consumed.

Clearly, this heat is not only wasted, but also a burden.

"Abort the reaction."

[Roger.] ］

Drip! The pressure in the vacuum chamber suddenly and rapidly decreases, and the fusion reaction is aborted.

Hiss! A stream of refrigeration spray looms over the mini-machine.

The nuclear fusion reaction created by the neutron pressing method can be stopped anytime and anywhere, even if the system fails, it is very safe.

If the condensed matter vacuum chamber fails, then the fusion reaction will not take place; If there is a failure during the reaction, once the condensed matter vacuum chamber fails, there is no pressure to press, and the nuclear fusion reaction will immediately neutrons; The DD nuclear fuel itself is non-radioactive, and the product helium is also non-radioactive.

The most likely danger is the leakage of unpressed, high-temperature plasma, but at most some of the equipment will be burned out.

In particular, large neutron press reactors do not allow personnel to enter the core area during operation, so even if an accident occurs, the risk is very low.

Huang Haojie didn't care about the small computer that was cooling, but turned around and looked up the information on the holographic computer.

He must find a way to deal with the unusable thermal energy, otherwise the miniaturization of the fusion power generation system will only be useless.

Especially when it is installed on the mecha, such a large amount of thermal energy can be sensed by those infrared monitoring devices at once.

In the holographic computer, I entered the keyword search [heat, power generation, reuse], and soon a lot of information jumped out.

These materials are available both at home and abroad, and they are the internal databases that Zhong helped collect, which can be said to be the largest scientific research database in the world.

After some searching, there are not a few materials that have entered Huang Haojie's sight.

Among them, [ion engine] [photonic engine] [temperature difference power generation] was highlighted by Huang Haojie.

The reason why the ion engine is focused on is mainly because the ion engine can directly use nuclear fusion helium ash and the photothermal heating of nuclear fusion inert gas.

The helium plasma and the heated inert gas plasma are ejected, and in this way a reaction force is created to push forward.

The photonic engine uses the light radiation at the time of nuclear fusion, and then reflects the photons through the mirror, which is similar to the ion engine.

Ion engines and photonic engines are very useful for the spacecraft of the future, and each has its own advantages in terms of applications.

The ion engine can use helium ash exhaust gas, but the optical radiation needs to be converted twice; Photonic engines, on the other hand, can only use light radiation, not heat and helium ash exhaust gases.

And whether it is an ion engine or a photonic engine, it is very unsuitable to be used in the atmosphere, they have a congenital defect, the thrust is relatively small compared to the chemical power, even if nuclear fusion is launched, it is still difficult to cover up their congenital defects.

Photonic engines and ion engines are only suitable for use in outer space, especially in long-distance outer space, because their specific impulse exceeds 10,000, and they can continuously accelerate and push the flight speed to very high speeds, which is difficult to achieve by chemical power.

If you use the current Qinglong-class spacecraft to fill up the fuel, set off from the Blue Star synchronous orbit to Mars, add the gravitational slingshot, and calculate the bearing and time (the closest thing between the Blue Star and Mars is about 55 million kilometers), the spacecraft can reach about 16 kilometers per second.

At this rate, it still takes about 40~42 days.

If a geostationary orbital mass projector or a lunar mass projector is used, the speed can be increased to about 40 kilometers per second, and Mars can be reached in as fast as 15 days.

If a photonic engine or an ion engine is used, accelerated by a mass projector, and then continued to use engine propulsion, it is estimated that it can reach Mars in about 10 days at the earliest.

But these applications are only suitable in outer space, and in the atmosphere, that little thrust with a mass of 1 ton is enough to fly, let alone use ion engines or photon engines to go to outer space.
