This time it is said that it is a scientific research exhibition, in fact, it should be said that it is more said to let Zhou Cheng comment, of course, the school may also have the meaning of letting Zhou Cheng invest and cooperate, but it has not been broken, who knows.

The students in the first three rows are all outstanding designers selected by the school this time, and they all brought their own products, or brought their own product design concepts, the purpose is of course similar to the school, either they want Zhou Cheng to value and then cooperate in development, or they simply want Zhou Cheng to comment on a few words.

"Okay, please have the first one, Xu Fei!"

A young man who looked like a student stood up excitedly, his voice trembled a little, he raised his glasses and bowed to Zhou Cheng, and then knocked a few times on the computer, and a PPT appeared on the projection screen.

"Mr. Zhou, this is my own design of the breathing charger, the general principle is to let people breathe to achieve the purpose of charging or storing electricity, using the air flow of human breathing to drive a small turbine to generate electricity, so as to replace part of the traditional energy source. ”

Zhou Cheng looked carefully at the slides played, to be honest, this invention is quite creative, in fact, many of the current inventions are also developed based on human facial features, such as glasses for eyes, headphones for ears, masks for mouth, but almost no corresponding nose.

The design is similar to a mask, and the natural breathing through the nose creates a flow of air that pushes a small turbine generator to generate electricity, just like wind power, but in a miniature version.

Zhou Cheng looked at him with a serious face, first praised a few words, and then turned around.

"It's good, and the technology is very mature, but it's a little late to invent this thing, and if you were born decades earlier, you might already be a billionaire." ”

This sentence made everyone laugh, and Zhou Cheng also smiled and continued.

"Now we have entered the era of graphene, all my electronic products do not need to be charged, and there is no charging interface, and this technology has been widely used in all aspects, even the TV we watch now, even the remote control does not use batteries.

You're a good thing, but what is it that you invented to charge something? Also, I think the data you provided is a little wrong, if you deduce according to the size of your turbine, it should take 12 hours to store about 5000mAh of power, who would take so long to charge or store electricity with this thing?

The third point is that if this thing is too heavy, people will definitely be uncomfortable, if it is too light, you need to improve your production skills again, the cost will go up, and the retail price will naturally go up, and it is estimated that even if it is made, it will not be easy to sell. ”

Just when the child was a little disappointed, Zhou Cheng said with a smile.

"But your idea is very good, if this product can be optimized, there should still be companies willing to invest, when the time comes, it can be sold as outdoor products, more suitable for those who have outdoor adventures, but now there are also pressure monomer power generation equipment, so the competition will be fierce. ”

"Thank you, Mr. Zhou!"

For Zhou Cheng's comments, undoubtedly made these students more excited, in previous years, when they participated in this exhibition, they either came to some conservative old men, or some brick families who didn't know anything, or some casual perfunctory panacea. Whatever you come up with, they'll say, well, yes, okay, okay, okay, pretty much something.

Zhou Cheng's comments are full of advantages and disadvantages, and he points out the follow-up development prospects to you, which is not a big help to them.

"The second, Zhang Yishan!"

"Hello Mr. Zhou, my invention is a paper watch! I have a real product to bring here, this is for you. ”

Zhang Yishan trotted two steps and took out a watch from a beautiful packaging box and handed it to Zhou Cheng, the watch is very thin, like a transparent plastic paper, almost no thickness, fully transparent, and the shape of an ordinary watch is almost the same.

Zhou Cheng smiled and put it on his wrist, touched the screen, and the screen immediately lit up, showing the time and calendar.

Zhang Yishan ran back to his seat and waited for Zhou Cheng's praise with a smile, but Zhou Cheng smiled, as if he was thinking about how to speak, and asked with a strange smile for ten seconds.

"The material of your watch is touch-sensitive, right?"

"Huh?

"You...... Do you know which company owns the patent for the touch-sensitive material?"

"Uh...... It seems to be ...... It's from your Qili Village......"

"So how profitable do you think you would be if you mass-produced this watch? young man? huh? haha...... , let me ask you again, do you know the health bracelet? Oh, also called the disease detection bracelet. ”

"Of course, I know this, and my design concept is the ...... that came up with this bracelet. ”

Zhou Chengdu was speechless, he really didn't know what to say now, could it be that he could just say that you know that you are plagiarizing, plagiarizing, and copycat health bracelets, he took a deep breath and said with a smile.

"Classmate, it's a good thing that you can study, but to tell the truth, although your watch is beautiful, it has been infringed, and the role is almost meaningless, because there are countless substitutes for his role in reality, in terms of cost performance, it is really not suitable for mass production, but it is still okay to give it to a friend as a gift. ”

Zhang Yishan's face was red, and he seemed to want to refute, but he probably didn't dare, so he could only stand in place and not speak, his eyes kept drifting, Zhou Cheng sighed and said directly.

"Your piece of paper is completely a simplified version of our health bracelet, regardless of the material, the design is exactly the same, if this can be regarded as an invention, then why don't I split the health bracelet into watches, thermometers, weather, maps, etc.

"The third, Bai Yang!"

A big fat girl stood up, and when they came, they burst into laughter, and the principal coughed to make it better.

"Mr. Zhou, I'm a foodie, so I invented a microwave oven projector. ”

Poof, laughing again.

Zhou Cheng also smiled, and said in his heart that this figure is blind with such a nice name.

"Mr. Zhou, my design concept is to allow all foodies to witness the wonderful changes in the food in the microwave oven. ”

Zhou Cheng smiled awkwardly, this is also an invention, but of course it can't directly hit a foodie's self-confidence, so he said euphemistically.

"Ah...... Girl, I think it's good that you have something invented, but isn't this invention a bit redundant?"

"Huh?

"Yes, don't you already have a fully transparent microwave oven now, you can see it more directly, you don't need to make a projector combination, right?

Poof, everyone laughed again.

……

"The fourth!

Another girl, as soon as this girl stood up, everyone laughed again, Zhou Cheng was stunned, and said that this girl is not fat, she looks the same as ordinary people, and it seems to have a little bit of Lin Daiyu's sad temperament.

"Mr. Zhou, what I invented is an animal thought reader!"

"Animal Thought Reader?"

Zhou Cheng thought he had heard it wrong, and asked again, and then saw that the PPT had been opened, and the thirty-four pages of slides were unfolded, and the more Zhou Cheng looked at it, the more frightened he became, and he said no, he really met a master for himself, which is already in the category of brainwaves.
