“…… This kind of inspiration comes from an extraterrestrial creation of a button battery, its basic theory and related formulas, please look at page 27 of the paper, where there will be a detailed discussion...... "I am surprised that a small button battery can bring such a great inspiration to mankind." I have to say that the UFO civilization is really countless times stronger than the new human civilization.

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

"The great scientist Albert Einstein's mass-energy equation E=mc^2 applies not only to nuclear energy, but also to chemical energy! The loss of quality is actually everywhere! ”

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

"This part of the reduced mass becomes energy, albeit with a small change in mass...... Our idea is to maximize the loss of quality and increase the amount of chemical energy released......"

Well, it's really a long time to see the series, Yu Yifeng looked distressed, he seemed to have heard of this statement for the first time, and to his surprise, most of the scientists nodded in agreement......

The change of chemical energy can also cause a change in mass!

Yu Yifeng dared to swear that it was the first time he had heard of such a statement. But seeing that the large number of materials scientists around him had no objections, he didn't dare to talk too much, saving himself embarrassment.

As for the energy level and electronic transition that is said later, I can't understand it even more.

He now knows that he is still a scumbag. It seems that we still need to strengthen our studies!

When Yu Yifeng walked out of the conference room with a disgraced face, he looked at Yuriko who was walking by, and unconsciously grabbed her, and suddenly felt that it didn't seem to be appropriate, so he quickly put it down.

Yu Yifeng was a little embarrassed: "Uh...... I said a long time ago that I wanted to treat you to dinner, so let's do it tonight. I still have some questions for you. ”

Yuriko was stunned, of course she remembered this meal. When she sent the Gauss rifle over, Yu Yifeng said that she would invite her to dinner, but it dragged on for half a year and lost her Gauss rifle...... According to the interest, it will take at least two meals to pay off, right?

Thinking of this, she frowned a little unpleasantly.

Yu Yifeng didn't guess that she was thinking so much, so he walked directly towards the cafeteria. And Yuriko, after snorting in a low voice, could only follow.

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

Yuriko said a little angrily, "Of course, isn't this common sense...... However, at the level of nine-year compulsory education, this is not really known. The teachers teach the conservation of elements before and after chemical reactions, including mass. ”

Yu Yifeng smiled bitterly and said, "It's indeed the first time I've heard of this point of view......

Speaking of this kind of serious topic, Yuriko no longer ridiculed Yu Yifeng: "While the alien materials have brought us a lot of inspiration, they have also corrected many of our conceptual errors. Many scientists are trying to discover and refine 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 in this regard." ”

Seeing that Yu Yifeng was sincerely asking for advice, Yuriko no longer sold Guanzi, and said directly: "When a chemical reaction occurs and energy is released, it must lose its equivalent mass, which is correct!" ”

"But the vast majority of chemical reactions release much less energy than common nuclear reactions. As a result, the mass loss of a chemical reaction is often so small that even the most sophisticated instruments cannot measure it, and can only be estimated from the energy released by the reaction. ”

"Let me give you an example, 1 mole of nitroglycerin explosion 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. Normally negligible......"

The two of them walked into the cafeteria, ordering food and chatting about this strange topic. However, this seems to be a common thing in the cafeteria, and the men and women who come and go around are all talking about science and related things. Even...... Didn't hear anything else!

Yu Yifeng pricked up his ears and eavesdropped for a while, what electromagnetism, high-energy batteries, nuclear energy...... There are all kinds of topics. It seems that this wave of science is blowing a bit hard, and he himself still enjoys this atmosphere very much.

Yu Yifeng suddenly found that Liriko ordered cheap vegetarian dishes, and he hurriedly said, "Have you lost weight?" Feel free to order, don't be polite with me! ”

Yuriko was stunned, she was thinking about various scientific questions in her mind just now, but she didn't react. She thought she was eating her own as usual.

It's a pity that she is really a little poor, and she is a standard foodie, she can't stand the temptation of high-end luxury food, and almost all of her monthly salary is filled in her stomach, resulting in a few days at the end of the month often having to eat vegetarian.

Thinking that it was Yu Yifeng's treat today, she was not polite, and pressed her fingers on the computer screen, "This, this...... And this! ”

Yu Yifeng's eyebrows jumped, what kind of submarine crayfish, crab roe rice cake, kelp sushi, everything is very expensive. But I was surprised for a moment, he is a typical representative of wealth, and his salary is the highest on the Noah, and he usually can't spend it at all, so he eats it...... Of course, he himself still follows the new currency system and does not engage in specialization.

"So...... Will Mr. Felix's invention of the battery bring about a qualitative change in the energy system? Yu Yifeng sat at the dining table and continued to ask.

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

"No, no, no!" Yu Yifeng hurriedly waved his hand, "I'm referring to the military aspect, can you make laser weapons or particle beam weapons from this?" ”

Yuriko was enjoying the food and thinking at the same time, obviously, Yu Yifeng's sumptuous meal had a very good buying effect.

"Theoretically, it's barely possible, but it requires a suitcase-sized battery with only one or two shots." To make the weapons you mentioned, we need batteries with higher energy densities to do that. ”

"No matter how advanced the battery is, it is a nuclear battery or some superconducting battery. The radioisotope batteries that we can do in our current laboratory use strong radioactive elements such as plutonium-238 and curium-244, which will decay slowly and produce electrical energy...... It's at least hundreds of times stronger than the best chemical batteries! ”
