206, Molecular Sieve

After Yang Qing finished installing the four electromagnetic shielders, the sky above the base was enveloped by a layer of electromagnetic fields.

In fact, the most special thing is that this electromagnetic field has boundaries and is located at several shielding towers.

Outside them, although there will be a small amount of magnetic field leakage, it will quickly attenuate beyond one kilometer away from here, and will eventually be absorbed by the lunar soil.

Four electromagnetic shielding towers, their other identity is signal transmission towers.

With a built-in space wave base station, there is no need to pull optical cable lines. In a base with a severe shortage of human resources, even if it is a little wasted, it is a better solution.

Even if lunar orbiting satellites are launched in the future, space wave base stations will still be needed on the ground to convert electromagnetic waves.

After all, with the current capabilities of the base, there is no way to make every mobile phone support space wave communication, so now Blue Star's technology is still the main one.

By this time, communications in the entire base, covering an area of ​​10,000 square kilometers, became clearer and clearer. Even if it was dawn and the sun was shining directly, there would be no interference.

Of course, this kind of defense is not very capable. Cosmic rays and solar wind will inevitably be mixed with some high-energy neutrons, which are not affected by electromagnetic fields.

Therefore, you must wear a spacesuit when moving outside the base.

Although even Yang Qing couldn't do it without wearing a spacesuit and moving in a vacuum environment, let alone ordinary people.

When an ordinary person is exposed to a vacuum, it only takes a few seconds to lose pressure and lead to death.

Although Yang Qing's spacesuit appears to be light and thin, the surface material can actually withstand the impact of high-energy neutrons.

Yang Qing made a circle in the sky. His consciousness sensed that the cosmic rays coming directly from deep space turned a large angle under the influence of the electromagnetic field. Some of them were directly reflected and returned to space. , part of it flew out parallel to the magnetic field, and then landed outside the magnetic field along the edge.

Therefore, outside the shielding layer, the intensity of cosmic rays has increased to a certain extent for a time.

The army of engineering vehicles on the ground has pushed the entire lunar soil ten kilometers away, revealing a huge circle with the base as the center.

The outer circle was filled with smoke and dust, but the inner circle had already calmed down.

There are already a large number of robots running out from inside and starting to lay solar panels.

This kind of panel is different from the ordinary solar panels on Blue Star, even though their principles are the same.

Without the obstruction of the air, the sunlight on the moon is much hotter than that on the blue star. During the daytime for half a month, the position with almost direct sunlight can receive the strongest sunlight, and therefore, it will heat up faster.

Even on the surface of the moon, the surface temperature will soar to more than 100 degrees Celsius during the day, let alone those ordinary black solar panels that are better at absorbing heat.

It is difficult to dissipate heat in a vacuum. The entire solar panel is like being shut in an insulated box, and the temperature can soar directly to 200 degrees.

Although the higher the temperature, the more conducive to the photoelectric effect, temperatures of more than 200 degrees or even higher have a huge impact on the life of solar panels.

To this end, Yang Qing and Xiao Ai not only referred to the two major aerospace countries, the United States and China, but also took great pains to design the solar panels for aerospace use by adding cooling devices to each solar panel.

The cooling device is still the Frost Array, but its starting temperature is at one hundred degrees, and the lowest temperature will not be lower than forty degrees, ensuring maximum power generation efficiency.

Although the frost array uses spiritual energy, the electricity emitted by the solar panels must also be converted into spiritual energy. If you consume part of it yourself, it is considered a due loss.

Moreover, this frost array can also ensure that the battery panel will not cool down excessively during the half-month of darkness. Otherwise, at the moment when hot and cold alternate, it will easily cause damage due to uneven cold and heat.

The robot below was busy leveling the site and fixing the panels. Soon, a light white, shiny solar panel appeared on the ground.

And this area is still gradually expanding in response to the expansion of engineering vehicles.

The working range of the engineering vehicles is naturally 10,000 square kilometers under electromagnetic shielding. In addition to replacing the spiritual stones, they are working tirelessly, leaving behind huge piles of lunar soil on the way, like hills, waiting for deal with.

Yang Qing watched the robot's work for a while, turned around, and returned to the base.

After dinner, I checked the most important core components of the fusion reactor, and then had a good sleep on my big bed.

When he woke up again, it was already Blue Star time, six o'clock the next morning.

However, in the base and on the moon, everything is still the same and has never changed.

"Master, helium 3 has been extracted, nearly one kilogram, and you can start building the fusion reactor at any time."

The gases obtained from the still are continuously separated.

Everything else is fine, except that the separation of ordinary helium and helium-3 is a hassle.

There is only one neutron difference between them, but they are still inert gases, and no chemical reaction will occur at all.

Just like the uranium-235 required for the first atomic bomb on Blue Star, gas diffusion or centrifugation is generally used to separate these two isotopes.

However, both methods require a huge amount of energy, and the base obviously does not have so much spare energy to separate helium-3.

Therefore, the base uses molecular sieves to separate helium-3.

That is to say, artificially create a sieve to sift out helium-3, leaving only helium-4.

It is of course extremely difficult to use Blue Star's technology to create such a sieve. After all, the difference between the two isotopes is only one neutron, which is almost the same, and no one can make a sieve that can be applied.

However, what the Blue Star people didn't expect was that there was Yang Qing in this world, a magical method like weapon refining, and an auxiliary tool like divine consciousness.

Yang Qing worked hard for more than a month before finally making several such sieves for the separation of helium-3, which also brought great convenience to Xiao Ai.

After the separated helium gas is pressurized and passed through a molecular sieve, extremely pure helium-3 can be obtained.

All of it is helium-3, and the only impurity is hydrogen. After all, among the distilled gases, they are the most abundant and the closest.

Although one kilogram of helium-3 is not much, as a fusion raw material, after complete reaction, the energy released is extremely large, enough for a fusion reactor to operate with a power of one million kilowatts for a month.

"Then start building the fusion reactor!"

Yang Qing didn't have any reason to object, he said with some expectation.

Following his words, the reactor core, which had already been installed on the transport vehicle, as well as various auxiliary accessories, were pulled and driven outside the base.
