Back to 1980: Please Love Me Again

Chapter 342 An Exciting Discovery

Beautiful country, Kennedy Space Center.

Zhao Wenmu turned his head to look, and he was really an acquaintance.

Zhuge Xian.

The other party was quite surprised when they saw him.

"You two little comrades Zhao, I didn't expect that we would meet again here!"

Seeing the two brothers and sisters, Zhuge Xian took the initiative to greet them with a smile.

"Yeah, it seems that we really have a destiny!"

Zhao Wenmu responded with a smile, and then introduced Zhao Wenjun and experts from the Huaguo Academy of Agricultural Sciences to Zhuge Xian, who seemed very happy.

It is indeed a happy thing to meet so many compatriots in a foreign country.

Zhao Wenmu invited Zhuge Xian to have a meal together, and the latter readily accepted this time.

When Zhuge Xian learned that Zhao Wenjun and others had come here for space breeding, he was immediately in awe.

"Space breeding is a cutting-edge technology. This experiment is expensive, right?"

he asked tentatively.

"Yeah, the charge per gram of load has almost reached 1000 US dollars! Several tests are expected to cost 1000 million US dollars. This stuff is really costly!"

Zhao Wenmu couldn't help complaining.

If the Junmu Group wants to earn 1000 million US dollars, it will take a year of the monkey!
"Yes, but there is no way. The entire space shuttle system has more than 2000 tons, but the actual payload is only about 20 tons. Indeed, every gram of load is very precious."

Zhuge Xian sighed.

"what?!"

Zhao Wenqiu was very surprised.

"Comrade Zhao Wenqiu, the total weight of the Challenger space shuttle, external fuel tanks, and booster rockets exceeds 2100 tons, but its total thrust is only 2600 tons, and the actual payload is almost 22.5 tons."

Zhuge Xian explained seriously.

"22.5 tons is already an astonishing figure!"

"The weight of the space shuttle is too big! If it weighs only 1000 tons, wouldn't it have a payload of more than 1100 tons?"

Zhao Wenqiu is really good at whimsical ideas.

"Haha, this is impossible. The weight of the liquid hydrogen and liquid oxygen fuel in the external fuel tank of the space shuttle exceeds 500 tons, and the two solid rocket boosters also weigh hundreds of tons. It can be said that the entire system is fuel It's nearly 1000 tons."

"There isn't much to lose weight on the entire space shuttle!"

Reducing the weight of the space shuttle, and more precisely, reducing the weight of any spacecraft, is a major research topic for aerospace scientists.

Let alone a thousand tons, even if it is to lose one kilogram for the space shuttle, scientists have to think hard for several months.

"Isn't there a more efficient fuel?"

Zhao Wenqiu exerted the spirit of seeking knowledge beyond the casserole and asked tirelessly.

Zhao Wenmu had a flash of inspiration, and he seemed to answer the words unintentionally:
"It would be great if it was replaced by controllable nuclear fusion. The space shuttle goes back and forth to the surface once, and it is estimated that it can't even consume 100 grams of nuclear fuel."

"If the Challenger carries a thousand tons of nuclear fusion fuel, it is enough for it to fly out of the Milky Way."

His rambling nonsense successfully caught Zhuge Xian's attention. After all, this future is a master in the field of controllable nuclear fusion research in Huaguo.

"Not to mention how difficult it is to realize controllable nuclear fusion, the weight of the fusion reactor itself may be thousands of tons, how to install it on the space shuttle is a big problem!"

"Xiao Zhao, your plan is just one of controllable nuclear fusion, and it would be lucky for mankind to solve it within 50 years! As for the miniaturization of fusion devices, it will take decades to research it!"

Zhuge Xian is a scientist after all, and he pays great attention to rigor when speaking.

In fact, he feels in his heart that if controllable nuclear fusion can be realized within 100 years, it is already a collective incense for mankind.

Even from a pessimistic point of view, it is hard to say whether it can be realized.

Once controllable nuclear fusion is mastered, it means that human beings have unlimited energy.

Infinite energy, what is the concept of these four words, in fact, few people will understand.

Since the development of human beings, all development and progress are in the final analysis the development and progress of energy utilization methods, and the level of energy mastered by people is constantly leaping.

In the primitive period, what humans first mastered was their own physical strength, and then they mastered the use of fire to obtain chemical energy, and domesticated animals such as cattle and horses to use their physical strength. The energy utilization level of human beings in this period was undoubtedly extremely low.

The annual energy consumption level of all human beings is not even comparable to that of a small town today.

In terms of the power of a single individual, the energy power of human beings at that time may only be tens of watts.

Later, with the improvement of productivity, human beings began to use wind power, water power, fossil fuels and other energy sources, which are actually solar energy in the final analysis.

After the sun's energy reaches the earth, it is stored in fossil fuels, stored in the drop of water level, stored in the difference of atmospheric pressure, and then used by human beings.

At this time, the energy power of human beings has probably reached several hundred watts.

With the further development of productivity, human beings began to directly use solar energy and nuclear energy. Energy sources have become more diversified, utilization efficiency has been improved day by day, and the demand for energy has also increased day by day.

Even so, the current total energy consumption of human beings is even less than one ten-thousandth of the total incident energy of the sun!

And that's just the energy from the sun hitting the earth.

Once the infinite energy is mastered, human beings will truly enter the so-called extremely materially developed society!
That is, the ideal social state presupposed by Marx.

"Besides, outer space is almost a vacuum. If a human spacecraft only relies on controllable nuclear fusion for energy, it also needs to carry a large amount of matter to serve as a working fluid for the spacecraft engine."

Zhuge Xian continued to add.

Zhao Wenmu had indeed neglected this point.

Outer space is different from the earth's atmosphere. There is no air in outer space. If the spacecraft wants to accelerate its flight, it must continuously eject matter backward.

This reminded Zhao Wenmu of a line in "Interstellar":
Newton's third law tells us that something must be left behind.

If the Eternal wants to escape from the black hole, it has to leave Ranger 1 and Ranger 2 behind.

If the spacecraft wants to continuously accelerate in outer space, it has to drop the working medium it carries.

Just like the Challenger space shuttle, if it wants to enter Earth orbit, it has to drop the external fuel tank and booster rocket.

"That is to say, even if humans have achieved controllable nuclear fusion and miniaturized the fusion device and put it on a spacecraft, they still have to carry a large amount of air and other working fluids to set off."

Zhao Wenmu said a little dejectedly.

"It's like this. Of course, the working medium does not have to be air. Rocks and soil should also work. Just see what the engine looks like at that time."

Zhuge Xian didn't feel that there was anything to be depressed about.

Interstellar voyages are too far away for human beings.

In his opinion, it would be more reliable to develop the moon at the door of his house first.

"Hey, the Wandering Earth is really reliable! No wonder humans dug up all the mountains in the novel, and the whole f*ck was sprayed into outer space by planetary engines!"

Zhao Wenmu muttered without beginning or end.

At this moment, the mobile phone next to her suddenly rang.

"Hello, who is it?"

Looking at the mobile phone in his hand, Zhao Wenmu became even more depressed. When will this thing be available in China? I'm so anxious!
"Hello, Mr. Zhao? I'm Mel, good news! The Lady Arcato has been found!"
