Chapter 414: Ecological Greenhouse

After Liu Xiu asked this question, Liu Qi calmly opened the three-dimensional virtual map of Wandering Blue Star and said:
"When I say it's easy to build, it's because we have two major material technologies that have made it extremely easy to build a greenhouse. First of all, under normal circumstances, the most expensive part of building a greenhouse is the main frame of the greenhouse. For a large-scale ecological simulation greenhouse like ours, the height of the greenhouse should be at least one kilometer. Once that happens, the cost of building the main frame of the greenhouse alone is not small."

Liu Qi paused for a moment, then pointed to the 20,000 propulsion planetary engines densely packed in the northern hemisphere on the three-dimensional virtual map and said:

"But now with it, we don't need to worry about building the support for the ecological simulation greenhouse!"

However, just as Liu Qi finished speaking, Tu Hengyu said:

"But although the height of these planetary engines is sufficient or even exceeds the standard, the distance between these planetary engines is more than 100 kilometers. Such a long distance is a great test for the construction materials!"

Regarding Tu Hengyu's ammunition, Liu Qi smiled confidently and said:

"I said before that it was because of the breakthroughs in two material technologies that I dared to use the planetary engine as a support to build an ecological greenhouse! Although a hundred kilometers is a bit far, the carbon nanotube cables that were once used to build space elevators can still connect a hundred kilometers without any problems!
We can just weave a huge net based on carbon nanotube cables, and then cover it with nano silver foil to form a completely reflective surface, which can reduce the loss of heat radiation by 30%! "

Liu Qi's words really made Liu Xiu excited. After all, if he followed Liu Qi's method, he could save a lot of money on building greenhouse supports.

And because the planetary engine is as high as 11,000 meters, it is completely possible to directly build a greenhouse at a height of 10,000 meters and directly include the troposphere, which can also solve the rainfall problem.

After all, the average height of the troposphere in the atmosphere is only 8,000 to 10,000 meters!
As for the nano silver foil that Liu Qi mentioned before, it was not actually invented by the materials scientists on the Wandering Blue Star, but was originally invented by scientists on Blue Star No. 2. It is a nano silver foil with an anti-color rate of 99.9%.

This nano-level silver foil not only has a high reflectivity of reflected light, but also has very good strength. Of course, although it is made of silver, this basic material is the most abundant in the universe.

In addition to the high-reflectivity nano-silver foil contributed by Blue Star No. 2, it is also an important reflective material for manufacturing star-destroying laser cannons!

It has already become a strategic-level weapon manufacturing material.

Of course, it can also be used to transform the ecological environment. After all, generally speaking, the ground will absorb 70% of the light that shines on the ground, and the remaining 30% will be reflected back, resulting in a huge waste of energy.

Of course, this little bit of waste is a drop in the bucket for a star and it doesn't matter at all. After all, it will continue to emit light regardless of whether it absorbs the sun's light or not.

Therefore, there is no such thing as waste. However, if the wandering blue planet irradiates itself with light, its properties will be different.

If we can save 30 percent of this energy, we can do a lot of things.

And the most important thing is that this nano silver foil factory is ready-made. After all, a lot of nano silver foil was used when building the star-destroying laser cannon!

So naturally, many nano-silver foil production lines were set up. Now that the star-destroying laser cannon has been built, and the nano-silver foil is not a consumable, Liu Xiu is thinking about whether to dismantle the nano-silver foil production line!
However, after hearing Liu Qi's plan to build an ecological greenhouse, Liu Xiu felt that he could still make use of it.

Moreover, nano silver foil can not only block the light reflection from the ground, but also has a good thermal insulation effect. After all, when the light heats the ground, it will naturally form infrared thermal radiation to evaporate its own heat.

But don't forget that infrared thermal radiation is actually a kind of light, so it can naturally be reflected back by the nano silver foil, thereby keeping warm and blocking cold wind, preventing thermal radiation and air convection heat dissipation.

Liu Xiu was so excited that he immediately decided: "In this case, let's build a greenhouse covering 10,000 square kilometers to see if it works! If it works, we will continue to promote it. If not, we will just treat it as a trial and error!"

With Liu Xiu's opening words, the 10,000 square kilometer ecological greenhouse experiment officially began.

The reason why we chose 10,000 square kilometers is naturally because the distance between planetary engines is 100 kilometers, so the area of ​​the greenhouse created by four planetary engines as the pillars of the ecological greenhouse is naturally 10,000 square kilometers.

Building a greenhouse covering 10,000 square kilometers is not a difficult task. After all, in terms of engineering workload, it only requires pulling a net between four planetary engines and then laying nano-silver foil on it.

So even though the construction had not started in full swing, everything from design to construction was completed in just half a year.

The actual effect is naturally very good. Although at this stage, the ecological greenhouse is still leaking air on all sides, the hot air sublimating upwards has already made the nano-silver foil of the greenhouse swell.

As hundreds of high-power floodlights were turned on, the temperature in the greenhouse began to soar immediately.

In just half a day, the temperature had dropped from minus 80 degrees Celsius to minus 20 degrees Celsius.

Liu Xiu was naturally very satisfied with this result.

When the temperature is around minus 20 degrees Celsius, there is no need to wear winter clothes, a thin down jacket will be enough.

And because of the genetic enhancement drug, even if the oxygen content in the atmosphere of the Wandering Blue Planet is only 10%, it is still possible to survive without an oxygen helmet.

Of course, as life expectancy doubles, the natural result is explosive population growth. The original population growth should be the number of births minus the number of deaths.

However, with the popularization of Liu Xiu's gene enhancement drugs, there will be no deaths in the next 150 or even 200 years.

Because Liu Xiu's genetic enhancement drug can extend his lifespan by 300 years, not to mention the extinction of the death population.

And as the elderly people in their sixties, seventies, eighties and nineties return to their youth, the youth that was originally gone naturally returns.

Just like Qin Huairu, she was over 140 years old and still able to give birth to children.

Therefore, those people in their seventies and eighties who have regained their youth can naturally create a new life.

Those whose spouses are still alive can just contact them directly to resolve the issue, while those whose spouses are no longer with them will naturally want to remarry.

This is just like the case with Liu Qi’s grandfather Han Ziang, who also found an old man in his eighties who had received injections of genetic enhancement drugs.

Liu Xiu looked at the Wandering Blue Planet, whose population had exceeded 7 billion in just three short years. Liu Xiu understood that given the current situation, even if the entire Blue Planet was covered with ecological greenhouses, there would be no way to provide enough living space.
