Of course, everyone present also knew that thoroughly studying Blackbird would not happen overnight.

The technology content in it is too strong, they need to dilute it a little bit and then drink it into their mouths.

"Dad, how long can this Dongfanghong sing?"

Yang Xiaotao sat opposite Ran's father. After watching the Chu-Han dispute between Mr. Wang and Mr. Zhang for a while, he turned around and asked, feeling uninterested.

Ran's father was thinking about the next work arrangements, and he came back to his senses when he heard Yang Xiaotao ask, "It should be more than twenty days. This time I used a battery. If it runs out of power, it won't play!"

He also heard about this from the Second Machinery Department, but he didn't know the details.

However, these twenty days are enough.

Thinking of Dongfang Hong who had been listened to by the whole world for more than twenty days, he felt his heart surge.

Yang Xiaotao nodded, this is similar to the situation in later generations.

At the same time, it also proves that even if his appearance has advanced the time and accelerated the process, it has not changed the original flavor.

“If only there were solar cells!”

Yang Xiaotao muttered, and Zhang Lao, who was resting on the back of the chair behind him, opened his eyes when he heard it, "What are you talking about? Solar cells?"

Yang Xiaotao was startled by the voice behind him and leaned towards Mr. Zhang who was lying on his back.

Only then did Yang Xiaotao realize that he had let the news slip. This solar cell is still in the laboratory and has never been heard of in China.

However, Yang Xiaotao was not surprised. He just looked at the sun outside and said, "You see, this sunlight is also a kind of energy."

"Then why not use this energy as a battery?"

Yang Xiaotao's words made many people in the carriage look over. Director Yan was chatting with Mr. Qian. When Yang Xiaotao said this, he immediately became interested, "That's a good thing to say."

"There are many types of energy. The coal and oil we use all contain energy."

"There's even wood for the fire."

"So what Xiaotao said about solar energy is correct."

Director Yan suddenly interrupted, asking everyone to focus on solar energy.

It's very boring in the carriage anyway, so it would be nice to have some fun.

Qian Lao rubbed his eyes and said, "Solar energy is a good research direction."

"If the satellite wants to operate in space in the future, this battery is one of the solutions."

If you have money and keep talking, the topic will become more interesting.

"However, how to make solar cells is not easy. At least there is no research in this area in China."

"Even abroad, there are not many studies and the effect is not great."

Yang Xiaotao listened and nodded from time to time.

Mr. Qian looked at Yang Xiaotao, "Since you brought it up, do you have any ideas?"

"Ah? My thoughts? I..."

"It's okay. If you have any ideas, just say it and let everyone listen."

Qian Lao spoke directly, and Yang Xiaotao couldn't refuse, so he explained, "Actually, I understand it from a biological perspective."

"Creature? Tell me."

Mr. Qian became interested. He originally thought that Yang Xiaotao would talk about some principles of solar energy conversion, but he didn't expect that it also involved the biological level. He had to listen carefully.

"When I was studying biology, the first thing I came into contact with was the photosynthesis of plants."

"It is the plants that absorb the energy from the sun into their bodies, and then grow and grow."

"In other words, the wheat and rice we eat contain solar energy, but this energy is converted by plants and is easier for us to absorb."

"And the coal and oil we use now are said to be products of plants buried underground many years ago."

"So I thought, since solar energy has so many uses, why can't we make solar cells?"

Yang Xiaotao said something, and most people could understand it, but the meaning behind it was far from satisfactory.

Most people don't even know what photosynthesis is.

After hearing this, Qian Lao lay on the backrest with a dazed look in his eyes.

Just when Mr. Peng was leaving, he went to find him and Mr. Wang to talk about the next work arrangements.

Mr. Peng told them that the Ninth Industry Department was about to be established.

Moreover, Mr. Peng recommended him and Yang Xiaotao to the organization.

He is the chief, and Yang Xiaotao is the deputy.

He was excited when he heard the news.

Mr. Wang was even more happy for him and even promised on the spot to fully support his work.

Moreover, considering the future development direction of the Ninth Machinery Department, they generously handed over part of the core project of the Seventh Machinery Department - "Computer Research" to give the Ninth Machinery Department additional weight!

Not only Mr. Peng, but Mr. Chen also had this idea.

If nothing else happens, there will be a meeting to discuss this matter when we go back this time.

And both of them will nominate at the meeting so that he can be prepared.

Originally, Mr. Qian didn't care about these things. If he had a choice, he would prefer to stay in the Seventh Machinery Department to complete his research.

But he thought that everywhere he went he was building for the revolution, so he didn't refuse.
Chapter completed!
