Beneath Deep Space

The storage of electrical energy is quite troublesome. Various chemical batteries have their own theoretical limits. Once the upper limit is reached, it can no longer be improved. Nuclear energy batteries have a higher upper limit, but they cannot be recharged and cannot be reused.

However, the issue of "electrical energy reserve" is very important for the safety of the spacecraft. When flying in the vast universe, various life-support equipment must be turned on at all times, so the battery is the last backup safety measure. Of course, the larger the reserve, the better.

Until now, people are still working hard to research ultra-high-performance batteries... Leaving aside various chemical batteries, the most outstanding one at present is undoubtedly a "large superconducting flywheel battery."

This kind of battery stores not chemical energy, but mechanical energy!

On the surface, this flywheel battery looks like a very huge turntable with a mass of one hundred thousand tons!

It is located in the gravity-free zone of the Noah.

When charging, the turntable will be rotated rapidly by force; when you want to discharge, use the high-speed rotating turntable to cut the magnetic induction lines to discharge.

Even though this is just a turntable, it contains the wisdom of generations of technicians. It uses a lot of superconducting magnetic levitation technology. If the turntable rotates at a high speed, it will undoubtedly be able to store a massive amount of kinetic energy due to its large mass. Moreover, the efficiency of converting kinetic energy into electrical energy is very high, reaching more than 90%.

"Does a low-level civilization also have such a method? The cost of a superconducting flywheel battery is not low." Yu Yifeng was a little surprised. The report was written by an authoritative scientist, so he did not doubt whether it was exaggerated.

He couldn't help but ask: "Has a low-level civilization also developed something good? Is it also a super flywheel battery?"

The female worker said somewhat amusingly: "Don't think too much about it. It's a very simple device: hydroelectric energy storage. They use the remaining solar power to pump a large amount of water to the reservoir during the day." upstream, converted into gravitational potential energy.”

"At night, when the solar panels do not generate electricity, the reservoir opens to release water, and then uses the kinetic energy to generate electricity... This can solve the problem of insufficient power at night."

"That's right..." Yu Yifeng was stunned and nodded again. The method of storing energy in the reservoir is actually quite good and is often used by people...

It seemed that there was nothing to learn from, so he was not discouraged and continued reading along the report.

This civilization uses solar energy on a large scale. Of course, it is not a natural preference for energy conservation and environmental protection.

But because... they run out of fossil fuels!

Two thousand and three hundred years ago, they used up almost all fossil fuels and uranium resources, and even the flammable ice that was easily mined on the seabed was almost used up. Naturally, huge wars broke out...

Fortunately... the Yufu Civilization survived that huge energy crisis. After recovering from the war, most of its population has been reduced. After struggling to survive the nuclear winter, and then slowly developing renewable resources, until now, a stable social structure has been formed.

"The number of countries has also shrunk from hundreds to fifty-three. There are local wars on the planet, but it is generally stable."

"In the end, after the nuclear winter passed, clean energy with solar energy as the core replaced the original fossil energy bit by bit... More than two thousand years have passed like this, and the entire planet has once again returned to its green mountains and green waters."

"Using up fossil energy will actually be a good thing for the entire planet!"

"Interesting." Yu Yifeng smiled, which was very similar to people's previous speculations.

If a low-level civilization does not have a reasonable enough system and ideology to complete "uncontrollable nuclear fusion" on a huge economic scale, then... the large-scale utilization of renewable energy will be the ultimate direction of a light-based civilization.

Because... solar energy is almost endless.

Generally speaking, the solar energy obtained by a planet is more than ten thousand times that consumed by low-level civilizations. It can easily support the survival of these indigenous people. It is just a matter of convenience...

According to research from the Earth Period, solar energy occupies too large an area, and the power generation is not stable enough, and the cost may be much higher than fossil energy. Because the energy consumption of manufacturing solar panels requires 2-5 years through recycling, which is still a long time.

I don’t know how to solve this civilization...

Yu Yifeng instantly thought of several possibilities. First, reduce the quality of life. There is no way, there is not enough energy, so we can only reduce it; second, reduce the population; third, vigorously research to improve the power generation efficiency of electric panels.

In short... life cannot be as moist as before.

He asked casually: "So, their utilization of clean energy is very impressive?"

"Yes, after so many years of research, even low-level civilizations have made great progress. Generally, 20 months can cover the energy consumption during the entire production and use cycle. Also because of the energy transformation, they no longer have enough power. To challenge nuclear fusion, we are going further and further in the utilization of solar energy..."

"They should be... better than us in this regard!"

The young girl stuck out her tongue quietly, seeming a little ashamed.

As a new human being of interstellar civilization, she is actually not as good as lower-level civilizations in the utilization of solar energy, which makes her quite embarrassed: "The photoelectric conversion efficiency of solar panels is much higher than ours... and the conversion of various electrical energy is also At a deeper level, there is something worth learning.”

Yu Yifeng smiled again and said: "This is normal. For more than two thousand years, renewable energy has been continuously developed, and it must be more powerful than us... Any civilization has something to learn from."

"While we are conducting scientific research, we can also get some solar panels to study..."

Of course, the main task of this scientific expedition is not to steal things, but to understand the culture of this indigenous civilization and collect more information. By the way, a small deep-sea scientific research base will be established to solve problems related to microorganisms so that people will not get sick easily.

The location of the scientific research base was chosen near the Antarctic of "Auriga 2". This place is inaccessible and is the best place to land secretly.

The mission was carried out by two hundred carefully selected researchers, both men and women, including various biologists, information scientists, linguists, etc., plus twenty soldiers.

These two hundred or so pioneers are all superhuman!

The immune system and survivability of superhuman beings are much stronger than ordinary people. They can adapt to local microorganisms faster and make immune vaccines more conveniently.

After a perfect immune vaccine is developed, even ordinary people will be able to travel to this planet.

Seeing that all the preparations were in place, Yu Yifeng walked to the line of soldiers and said loudly: "These more than a hundred biologists are our treasures and have conquered the ecosystems of several planets. There are others. Experts and authorities in all aspects, I won’t say much, just follow their instructions!”

"clear!"

"Set off!"

…

A week later, a small country in "Auriga 2" reported an inconspicuous news: satellites in the sky observed that several meteorites that had never been discovered before fell into the Antarctic region. These meteorites caused huge splashes and sank into the local ocean.

Regarding this news, except for some astronomy enthusiasts who paid a few glances, the whole incident did not cause much disturbance.

The universe is so big and there are so many meteors, tens of thousands of tons of them fall on the planet every day. If a few large meteorites fall near the South Pole, it doesn't seem to be a big deal.

Moreover, places like Antarctica are full of sea areas and do not have much economic value. Due to the extensive use of fossil fuels, a huge greenhouse effect was triggered more than 2,000 years ago, causing all glaciers to melt and causing a devastating blow to the ecosystem.

It was not until the subsequent nuclear winter that the thick ice solidified back again.

But after such repetitions, Antarctica no longer has much scientific research value.

Besides...the light intensity here is very weak, and it has no power generation value. The combustible ice has been dug out, and there is nothing except a few glaciers and the vast sea water.

So no one really plans to go into the ocean and spend a lot of effort catching meteorites...

However, a few days later, a quiet dark blue submarine emerged from the sea quietly... Its color was almost the same as the sea water, and it was sailing at a speed of sixty kilometers per hour.

Several figures emerged from the submarine, and the leader was none other than the soldier captain Zhao Yao!
