Chapter 278 Return and Upgrade

In this way, a solar power generation panel with a light energy conversion efficiency of 30% can only generate 150 watts of electricity per square meter on Mars.

On the Blue Star, even if the thick atmosphere of the Blue Star blocks 30% of the light, the intensity of the remaining light reaches one thousand watts per square meter. After conversion, a square meter of solar power panels can also emit 30% of the light. One hundred watts of electricity can still produce twice the power of Mars.

Fortunately, the atmospheric pressure of Mars is less than one percent of that of Blue Star, so it has no effect on the illumination of solar panels.

But even so, the solar power generation panels on Mars can only generate 150 watts per hour. Calculated to generate electricity for ten hours a day, it is only 1.5 kilowatt-hours of electricity, and 100 square meters is only 150 kilowatt-hours. Just electricity.

This amount of electricity may be more than enough to supply the Mars base with daily life needs.

But don't forget that at this time, the Mars base needs to keep ten vegetable greenhouses warm at night. You know, the atmospheric pressure on Mars is only one percent.

Therefore, the thermal insulation effect of Mars is extremely poor, and the temperature difference between day and night is huge. For example, even on the equator of Mars, the temperature during the day can reach 20 or 30 degrees Fahrenheit, but at night it will drop to minus 60 or 70 degrees Celsius. degree.

Therefore, if heating measures are not taken at night, the result will be that the vegetables in the greenhouse will be frozen to death by the cold night.

Of course, the double-layer insulation in the greenhouse and the ground isolation measures adopted during construction also mean that the vegetable greenhouse does not require too much energy to be insulated and heated.

In addition to the 100 square meters of solar power generation panels on the prefabricated house that was first built for people to live in, Liu Xiu also brought an additional 6,000 square meters of solar power generation panels.

Compared with glass greenhouses that can last for hundreds or even hundreds of years, film greenhouses with a service life of only more than ten years or even shorter will naturally be eliminated sooner or later.

However, whether it is electric heating or electrolysis, the amount of electricity required is huge. Therefore, the items that account for the largest weight of cargo on the space station are not actually living materials and construction panels. Instead, the largest items by weight are solar power panels.

Yes, in Liu Xiu's opinion, glass greenhouses will be the permanent building on Mars in the future, and film greenhouses are just a substitute during the transition period.

Solar power panels that can generate nearly 10,000 kilowatt-hours of electricity are enough to establish a small industrial cycle system on Mars.

In fact, the electricity consumption of the vegetable greenhouse is only a small part. The real power consumption is the mineral refining equipment brought by Liu Xiu.

As glass and aluminum can be produced on Mars, the corresponding counterpart is naturally a 200-square-meter glass greenhouse rising from the ground.

Of course, because all energy depends on the sun, this industrial cycle system can only carry out production operations during the day and stops at night.

...............

Time flies very fast, and a year has passed in the blink of an eye. In this year, the achievements of the twenty people led by Liu Xiu are huge, and they have established a glass processing industry from scratch. Factory, aluminum ore processing plant.

Because there was no way to use media, the mineral refining equipment Liu Xiu brought basically used electric heating or direct electrolysis for refining.

There was no way, because the capacity of the space station was limited, so Liu Xiu did not carry too many lithium batteries for energy storage, only energy storage batteries with a capacity of 1,000 kilowatt-hours.

Of course, everything here is naturally filmed and sent back to Blue Star. When people in the country saw Liu Xiu's impressive work at the Mars base on Mars, they were naturally full of praise and admiration.

As for other people on Blue Star, they also call Liu Xiu the pioneer of interstellar immigration.

And he also ridiculed Mi'ao's moon landing plan as a mere appearance that was just for a title and had no practical significance at all. However, as more than a year has passed, the conjunction period between Blue Star and Mars every 26 months is naturally coming.

So that night, Liu Xiu naturally held a meeting in the conference hall of the base to determine the candidates for returning personnel. Liu Xiu said to the eighteen people sitting there:

"Okay, let's discuss the candidates who will return to Blue Star this time!"

But what Liu Xiu didn't expect was that just after Liu Xiu finished talking about Wu Wanli, he said:

"Captain, we have agreed this time. Instead of ten people going back, just four people will go back this time! The construction factories here need manpower, and the greenhouses also need manpower to look after them. If we go back too many, then There are not enough manpower to maintain the production of greenhouses while continuing to build glass greenhouses. "

Seeing this, Liu Xiu naturally said nothing more. After all, maintaining the expansion of the Mars base is indeed a very important matter, so Liu Xiu naturally nodded in agreement.

In fact, Liu Xiu originally wanted to keep more people on Mars, but when he came, he originally said that half of the people would be returned this time, except for him, so it was naturally difficult for him to change his mind.

But since they are now actively requesting that only four be returned, Liu Xiu is naturally happy to see it happen.

Nothing strange happened during the return to Blue Star. Liu Xiu and the others just brought some vegetable seeds that had bloomed on Mars and some Martian soil, then ascended into space and entered the space station, and then boarded the space station. One of two return capsules.

The journey back was also boring and silent. More than seven months later, Liu Xiu successfully landed the Mars return capsule at the air force headquarters airport. After he walked out of it safely, the entire Blue Star was shocked and excited.

Because Liu Xiu's return and exit was broadcast live, everyone saw the scene of Liu Xiu coming out in high spirits.

However, I left Blue Star in 1979, and now it is already 1982 when I returned. The three years of going back and forth are really difficult. After all, there are so many three years in life!

However, on the second day after Liu Xiu returned to Blue Star, Mi Tuo and Su Tuo almost simultaneously proposed that they would implement the Mars landing plan in 1984, the year after next.

Liu Xiu was speechless about this, that's all for Mi Zuo. This guy who hasn't even completed landing on the moon is really clamoring for landing on Mars.

Of course, Liu Xiu also understood that this was actually a plan proposed by Mi Zuo and Shu Zuo because they did not want to watch Mars being monopolized by Liu Xiu.

After all, if they are ignored for a long time, when Liu Xiu's side completely develops on Mars, where will they still have a share?
So Liu Xiu naturally found the old dean again and wanted to ask the old dean to talk to the superiors to increase investment in Mars immigration.

However, after Liu Xiu met the old dean, he found that he had become even older after not seeing him for three years.

However, after Liu Xiu told the old dean about continuing to increase investment, the old dean said:

"You should talk about this matter yourself!"

Liu Xiu couldn't help but was stunned when he heard this. Wouldn't it be a bit overstepping for him to say it himself? After all, it was better for Anli to report the matter to the old dean than to tell him.

Regarding Liu Xiu's doubts, the old dean said:

"I'm old enough, and I have lost less and less energy in the past few years, so I recommended you to take over my position! The superiors have also agreed. Now that you are back, you will naturally take up the post. "
