It’s the height that confuses people. Not sure how you would float massive blocks up 600 feet. They would have needed more than a river.
Lift one big pool of water a few times, instead of lifting each and every stone individually. It's still a huge feat. I find it extremely questionanle that Egyptians, in the presence of even primitive hydraulic technology, would have gotten the pyramids done relying on metabolic energy alone. https://youtu.be/rxFXsoqbfrk
That concept is interesting but doesn’t explain how the Egyptians would have been able to deal with the water pressure at the base. The gates and pipe from the concept would need an explanation on how those technologies would have been implemented by the Egyptians.
You see it in the beginning of the video; simple locks. Submerge the channel horizontally to fill it, *seal the locks*... and LIFT. Once it's sealed, it's effectively a solid object that can be moved with people pulleys & leverage, to any location & any orientation necessary to float rocks. And let's be real...No one can argue that the Egyptians of all ancient cultures were bad at sealing things (but they may have been bad at treating their workforce like real people, who knows?) 😉😅
I’m not sure. In the video, the locks are in a plastic tube (which is tough enough to withstand the pressure of the small volume of water in the demonstration). How would the Egyptians have built such a thing that could have withstood the water pressure of a gigantic tube? According to AI, a tube 10 feet in diameter and 50 vertical feet would put pressure at the bottom of the tube of 700 lb/sq inch. On a 1 sq ft block of stone at the base, that would be 100,000 lbs pushing out for 50 vertical feet. For 500 vertical feet, that would be 1 million lbs pushing out. Not sure how they would have constructed a tube to withstand that.
These were not prehistoric people, they were fully evolved creative innovators like we are today. They could have lifted blocks one by one, but I seriously doubt they didn't also think to lift any tools, machines, animals or water to help the job get done before the emporer dies. 🤷♂️ For kicks, ask AI to generate some possible solutions besides pure slave labor that could conceivably have taken place, given Idunno, 50 or 100 years to beat the deadline of the kings death?

Construct tiered pools. Line with massive logs. Fill up with water, slide over. Rough idea but seems doable.
How about a water wheel driven crane? Pulleys are old tech...
Maybe. They could have used water as a counterweight. Just so long as they had strong enough ropes. Presumably they didn’t have steel cables and I have no idea what rope materials they had at the time. 🤷♂️
Maybe, but any explanation will need to address construction of the system and how they addressed the foundation and water pressure. For example, a series of linked pools like a set of locks going up 600 feet would have been its own engineering challenge. Would it have wrapped around the pyramid multiple times like a corkscrew? The more times it wrapped, the lower the water pressure on the lock gates, but the stronger the foundation and supports would need to be. What might have supported it? Maybe some sort of scaffolding system? Dunno. 🤷♂️
