You promised to build cars, so why did you go into the military industry?

In 1959, Freeman Dyson published a paper in the journal Science.

This is the first time the Dyson sphere has appeared in the public eye from a rigorous academic perspective.

The purpose of building the Dyson sphere was to capture most of the energy emitted by stars.

Undoubtedly, achieving such a grand goal will inevitably involve facing numerous unimaginable challenges.

But what if we take a different approach?

What if only a small portion is captured?

For example, placing a solar panel on Earth?

Forget about the scale; that's meaningless.

Tell me, isn't that right?

The average annual radiation in Linjiang County is about 1400-1500 kWh/m².

The peak sunshine duration is approximately 3.5-4.5 hours.

The average daily intensity is usually around 500 W/m².

If all goes well, this board can collect 2kWh of electricity today.

To put it simply, it can power a 1.5 horsepower air conditioner for 2 hours.

Gao Jingming pointed to a one-square-meter solar photovoltaic panel and introduced it to Li Ran.

In August, at noon, when the sun was at its strongest, Li Ran was so hot that he couldn't open his eyes.

"It can only keep the air conditioner running for two hours?" Li Ran fanned himself vigorously with a palm-leaf fan. "It doesn't feel that great."

I had heard that there had been a breakthrough, with photoelectric conversion efficiency reaching 40%, which is two to three times that of current mainstream products.

Two to three times! Not only is the increase huge, but the proportion is also high, almost half!

Excited, Li Ran ignored the heat outside and, without even eating, led a group of people to the scene under the scorching sun.

That's it?!

A whole bunch of people are here with you, basking in the sun, just to watch you demonstrate how you collected two kilowatt-hours of electricity.

Two kilowatt-hours of electricity! That's going too far, Mr. Gao!

Also! The internal code name for this photovoltaic project is "Project Dyson Sphere".

Can you be sure this is serious? Isn't this a bit too abstract?

Currently, the photoelectric conversion efficiency of mainstream commercial solar photovoltaic panels is typically between 12% and 17%.

"For a product this efficient, Mother Sun would simply feed it; it would only consume half a kilowatt-hour of electricity a day."

Gao Jingming wiped his sweat, as if he had thought of something, and added:

"Mr. Li, I'm just testing this!"

The solar photovoltaic panel in front of me is only one square meter in size!

Our production workshop has a building area of ​​approximately 24.7 square meters. If we covered it all with these panels, it would generate about 50 kilowatt-hours of electricity per day.

Our factory only consumes 30 kilowatt-hours of electricity per day!

It can also sell 20 kilowatt-hours of electricity back to the power grid.

At a price of 15 cents per kilowatt-hour, that's 30,000 yuan! Every day!

Upon hearing that he could make money in reverse, Li Ran perked up, using a palm-leaf fan to shield his eyes from the sun and forcing them to open wide.

The dark board in front of me suddenly looked much prettier.

Li Ran re-examined the solar photovoltaic (PV) panel that had been prepared.

He felt that the name "Dyson Sphere Project"... well...

How apt!

Anyone who objects to the name of this project will fall silent once they see this solar photovoltaic panel with a photoelectric conversion efficiency of 40%.

"Mass production! We must mass produce!" Li Ran waved his hand, issuing the top order, "Work like crazy for 100 days! Install it on the rooftops of every building in our manufacturing plant! Hey, Zhou Jie!"

Zhou Jie, who was feeling drowsy from the heat, immediately stood up straight: "Here!"

"There's no budget limit for this renovation, so we must hurry." After saying that, Li Ran pointed to Xu Qinghe in the crowd, "Qinghe, you'll be Gao's assistant this time, is that alright?"

"Mission accomplished!"

"Great! Very energetic!"

Lin Yu, who was standing to the side, couldn't stand it any longer and spoke up:

"Old Gao, what are your plans for BMS? Zhang Chengyuan isn't here, can you handle this?"

"Just do it by hand! I've worked on car BMS before, and this thing is much simpler than that."

In three days, the mass production process of photovoltaic panels was fully completed under Gao Jingming's design.

Two weeks later, the production line was completed.

Fortunately, the construction sites that had been shut down before the Lunar New Year were gradually completed and delivered over the past six months.

The photovoltaic production line was conveniently located in a corner of the new factory area.

As the factory's electrical system upgrade work gradually got on track, an invitation from CNSA was placed in front of Li Ran.

Invitation Letter Regarding the Invitation of United Industries to Visit the Satellite Launch Center to Observe the Launch of the Chang'e Lunar Exploration Mission Rocket

Rocket launch? Lunar exploration? Chang'e-2?!

Li Ran was somewhat surprised. What merit did United Industries possess to be personally invited by the government?

Could it be because of Wang Bing and the others again?

They should have come back long ago. Their absence during this time... could it be...?

Just as Li Ran was feeling a bit confused, Wang Bing contacted him.

"Mr. Li, have you received the invitation?"

Li Ran hadn't heard Wang Bing's voice for almost a year, and a wave of emotions washed over him.

"Received it, it really is..."

"Well. It's hard to explain clearly over the phone, but basically, the machine we provided was a huge help to them. Out of gratitude, they sent an invitation home."

"Okay! Okay! Okay! October 1st, right? I'll be there on time."

The phone call came quickly and ended quickly.

But Li Ran's heart remained unsettled for a long time.

It's hard to explain over the phone.

However, Li Ran could still guess some of it.

A die forging press capable of providing at least 25 tons of pressing force is used for things like rocket bodies, space stations, manned spacecraft, aircraft beams, and aircraft carrier beams...

Both can be die-cast!

This kind of national strategic equipment can do so many things in heavy industries such as aerospace!

"I remember the sixth-generation fighter jet made its maiden flight on December 26, 2024, right?"

Li Ran subconsciously touched his chin, feeling that he would see the sixth-generation fighter jet much earlier this time.

Could the aircraft carrier be launched ahead of schedule?

Originally scheduled for September 25, 2012, how much earlier can it be? Half a year?

What about the space station?

"Hiss... There are too many important things to do. I feel like one machine might not be enough." Li Ran clicked his tongue.

The reason why Wang Bing, Su Qing, and others did not go home after the machines went into production is also very simple.

Newly commissioned machines need to be debugged, right?

With the chief designer gone, any problems encountered during the debugging process require people to run back and forth, which is not only troublesome but also inefficient.

I might as well stay a little longer.

During the debugging process, it was discovered that the die-cast parts far exceeded expectations.

In a moment of excitement, it's only natural to send an invitation to the company where the meritorious contributor works, to visit and give them a commendation, in order to reward them.

According to the original plan, Chang'e was to be launched during the National Day holiday this year, and Tiangong-9 was to be launched at the end of September next year.

It appears that the process remains unchanged this year, and it is highly likely that the existing version of the Long March 3C will still be used to carry out the launch mission.

Next year, well, that's hard to say!

At least one of the rockets and the Tiangong space station must be rebuilt!

Maybe both of them were recast?
