Chapter 122 Technological Boom (2)

“…This inspiration comes from a button battery created by aliens. Please refer to page 27 of the paper for its basic theory and related formulas. There will be a detailed discussion there…” I was surprised that a small button battery could bring such great inspiration to mankind. It must be said that UFO civilization is indeed countless times stronger than the new human civilization.

Yu Yifeng listened with great interest at first, but then he was confused and dizzy, and could only follow everyone to page 27 in a daze.

"The mass-energy equation E=mc^2 of the great scientist Einstein is not only applicable to nuclear energy, but also to chemical energy! The loss of mass is actually everywhere!"

Felix held an experimental aluminum-air battery and said passionately: "In our daily lives, we have long learned to use the loss of mass to create energy... When two hydrogen atoms and one oxygen atom combine to form a water molecule, the mass of the water molecule must be less than the sum of the masses of two hydrogen atoms and one oxygen atom."

"This part of the reduced mass becomes energy, although the change in mass is very small... Our idea is to expand the loss of mass as much as possible and increase the release of chemical energy..."

Well, it's really a long-seen series. Yu Yifeng looked distressed. It seemed that he had heard this for the first time. What surprised him was that most scientists nodded in agreement...

The change in chemical energy can actually cause a change in mass!

Yu Yifeng dared to swear that he really heard this for the first time. But seeing that the large number of material scientists around him had no objections, he didn't dare to say anything more to avoid embarrassing himself.

As for the energy level and electron transition mentioned later, he couldn't understand it even more.

He only realized now that he was still a poor student. It seems that I still need to study harder!

When Yu Yifeng walked out of the conference room with a dusty face, he looked at Yuriko who was walking by and unconsciously grabbed her. Suddenly, he felt that it was not appropriate and quickly let her go.

Yu Yifeng was a little embarrassed: "Uh... I said a long time ago that I would treat you to a meal. Let's do it tonight. I still have some questions to ask you."

Yuriko was stunned. Of course she remembered this meal. When she sent the Gauss rifle over, Yu Yifeng said he would treat her to a meal, but it was delayed for half a year and her Gauss rifle was lost... According to the interest, it would take at least two meals to pay off, right?

Thinking of this, she frowned a little unhappy.

Yu Yifeng didn't guess so much of her thoughts, and walked directly to the cafeteria. And Yuriko could only follow after humming in a low voice.

"Let me ask, is there also a loss of quality in chemical reactions?" Yu Yifeng asked as he walked.

Yuriko said unhappily: "Of course, isn't this common sense... But according to the level of nine-year compulsory education, this is indeed not known. Teachers teach the conservation of elements before and after chemical reactions, including mass."

Yu Yifeng smiled bitterly and said: "This is indeed the first time I have heard of this view..."

Speaking of such a serious topic, Yuriko no longer laughed at Yu Yifeng: "While alien materials have brought us a lot of inspiration, they have also corrected many of our conceptual errors. Many scientists are working hard to explore and improve our scientific theories."

Yu Yifeng also nodded and said: "We are still in a state of half-understanding of the universe, especially me, I still need to learn more theoretical knowledge, and I need to ask you more about this."

See Yu Yifeng was asking sincerely, and Yuriko didn't keep him in suspense anymore, saying directly: "When a chemical reaction occurs and energy is released, an equivalent amount of mass must be lost, which is correct!"

"But since the energy released by most chemical reactions is much smaller than the energy released by common nuclear reactions, the mass loss of chemical reactions is often very small, so that even the most sophisticated instruments cannot measure it, and it can only be calculated by the energy released by the reaction."

"Let me give you an example. The explosion of 1 mole of nitroglycerin can produce 2700 kilojoules of heat, and the mass loss before and after the reaction is 3.074*10^-8 grams, which is very small. It can also be ignored under normal circumstances..."

The two walked into the cafeteria, ordering food while chatting about this strange topic. However, this seems to be a common thing in the cafeteria. The men and women coming and going around are all talking about science and related things. Even... I didn't hear any other topics!

Yu Yifeng pricked up his ears and eavesdropped for a while, all kinds of topics such as electromagnetism, high-energy batteries, nuclear energy... It seems that this wave of science is quite strong, and he himself still enjoys this kind of atmosphere very much.

Yu Yifeng suddenly found that Yuriko ordered cheap vegetarian dishes, and he quickly said: "Are you losing weight? Order whatever you want, don't be polite to me!"

Yuriko was stunned. She was thinking about various scientific problems in her mind just now, and she didn't react. She thought it was like usual, eating her own food.

Poor her, she is really a little poor, and she is a standard foodie. She can't stand the temptation of high-end luxury food. Almost all of her monthly salary is filled in her stomach, resulting in the last few days of the month can only eat vegetarian food.

Thinking that Yu Yifeng is treating today, she is not polite, and her fingers are randomly pressing on the computer screen, "This, this... and this!"

Yu Yifeng's eyebrows jumped. The crayfish, crab roe rice cake, and kelp sushi were all very expensive. But he was only surprised for a moment. He was a typical representative of the rich and powerful. His salary was the highest on the Noah. He could not spend it all at ordinary times. He ate it all... Of course, he still followed the new currency system and did not make any special requests.

"So... will the battery invented by Mr. Felix bring about a qualitative change in the energy system?" Yu Yifeng continued to ask while sitting at the dining table.

Yuriko looked at the sumptuous meal in front of her and said with satisfaction: "Of course it will, and life will be much more convenient. From now on, mobile phones only need to be charged once a month; cars can run more than 10,000 kilometers on a single charge..."

"No, no, no!" Yu Yifeng waved his hand quickly, "I mean the military aspect. Can it be used to manufacture laser weapons or particle beam weapons?"

Yuriko was thinking while enjoying the food. Obviously, Yu Yifeng's sumptuous meal had a very good effect of bribery.

She said vaguely: "Theoretically, it is barely feasible, but it requires a suitcase-sized battery, which can only provide energy for one or two shots. To make the weapons you mentioned, we need batteries with higher energy density."

"The more advanced batteries are nuclear batteries or some superconducting batteries. The radioactive isotope batteries that we can make in our laboratory currently use highly radioactive elements such as plutonium-238 and curium-244. They will decay slowly, and the electricity they generate... is at least hundreds of times stronger than the best chemical batteries!"
