"Professor Lü, I think we could lower our requirements a little."
"1,000 GPa-that tensile strength is just too difficult to achieve."
"If you think a small space elevator can't meet our cargo needs, we could always build a few more, couldn't we?"
Wei Rong tried to persuade him with "earnest concern."
Lü Yongchang stared blankly at the carbon nanotube before him.
After a long silence, he suddenly said, "That makes sense."
Before delight could appear on Wei Rong's face, Lü Yongchang continued, "You're right. Single-walled carbon nanotubes won't work!"
Wei Rong: "???"
He looked at Lü Yongchang in bewilderment.
Was that what I just said?
Lü Yongchang, meanwhile, seemed to have misunderstood the confusion on Wei Rong's face. "Don't you understand?"
"It's simple. Even with the most ideal structure, under the most ideal conditions, a single-walled carbon nanotube can only reach a tensile strength of 800 GPa. That's definitely not enough!"
"We need to work on multi-walled nanotubes!"
"Considering the reduction in tensile strength caused by the fabrication process, purity, and spinning methods..."
"To be safe, we need to raise the tensile strength of an individual carbon nanotube to over 1,500 GPa!"
Carbon nanotubes
Wei Rong stared dumbly at Lü Yongchang, then slapped his smooth forehead.
So Professor Lü hadn't listened to a single word I said?!
A hint of urgency entered his eyes. "But, Professor, the theoretical calculations for multi-walled carbon nanotubes are far too complicated. We don't even know their upper limit in GPa!"
Lü Yongchang chuckled.
"Doesn't that just show how much room there is to optimize multi-walled carbon nanotubes?"
Wei Rong: "..."
You can interpret it that way too?!
After some debate, Lü Yongchang unilaterally declared Wei Rong's objections invalid.
And so, Wei Rong "joyfully" began assisting Lü Yongchang.
"Wei Rong, help me check sample
