The Dendera 'Light bulb'

[ArMaP]

There have been many theories for the Great Pyramid(power plant, irrigation), anyone who has looked into it knows it is a device of some sort

The problem is that most people do not look at it and try to find what it was, they look at it and try to make it fit their own personal bias.

Drumm is the first one to look not only at the Great Pyramid, but many of the others as well.  The chemical staining allows them to be reverse engineered

Have you tried to reverse engineer something when you do not really know what it was for? You need to start from a known result to know how it worked. If you do not really know and are assuming a result, you may be able to find a solution that has no relation to reality.

Imagine someone presses the wrong button and everyone on the planet dies because a nuclear war.
Some decades later, an ET finds this object:



They may imagine it was a ceremonial tool (the easiest answer when you don't know what it may have been used for ) or they may try to get an idea about it (like it was used for some kind of electrical use, as it's metal) and try to imagine how they used it for that purpose.

They would be wrong in both cases, as this object is used to set the teeth of handsaws, I saw my uncle do that many times.

It doesn't seem you  are interested, nothing wrong with that.  Anyone wanting to do a deep dive should start at the red pyramid, a 3 chamber structure where the smell of ammonia in the last chamber makes it obvious what was being made there

I'm interested in history and in facts, I'm not interested in people that try to force fit existing things to their own preconceived ideas about any thing.

The fact that that specific chamber smells of ammonia today doesn't mean that it smelt of ammonia at the time it was used, so we need to assume that to apply the ammonia theory.

PS: what's so important about ammonia?

It is strange so much of history is lost, where are all the 1st generation gear devices that eventually led up to this advanced one?

There is one here:

I remember another device that was similar to the Antikythera mechanism, though less complicated, that is housed (as a reproduction) in some British museum, but I can't find a link to it atm.

Just means someone or something (such as rats) have been urinating in the chamber.

Afraid you are going to have to watch more than minute to get into it

Two features about the red pyramid
-There is a stop block at the end of the entrance shaft for the compression block to rest against

-There is a collection bowl still there today that leads back into the pyramid

"Ammonia is primarily used as a fertilizer precursor, with around 70% of industrial production dedicated to creating fertilizers like urea and diammonium phosphate to support global agriculture"

The Eyptians had a deity for it

The official explanation they give is bats, however other structures in Egypt with far more bats do not have the same smell

Sorry, I don't watch videos longer than a couple of minutes, videos force us to spend the time as the video creator wants, not as we want, and my time is precious.

Is there any sign of ancient Egyptians using ammonia based fertilizers?

Sure, it was in the last link..

Just as the other links gave a detailed break down of the chemistry and formulas, for those that are interested

Another point, chemistry often involves extreme heat and pressure.  The Egyptians didn't have access to pressurized steel tubes to contain these reactions, so they built theses rooms at the center of these massive stone structures to deal with that problem

There is no ancient Egyptian word for ammonia.
The name comes from Greek and Latin, not from Egypt, and it was named so because of the proximity to the Temple of Amun, not because Amun was the ammonia god.

It's ammonium chloride salts, and they were used in medicine, tanning and mummification.
Probably other uses as well. Possibly in fertilizer, but the Egyptians relied mostly on the deposits left by the annual Nile flood. They did supplement with various manures though.

Comparison pic of the Haber setup to the Egyptian setup

Both using 3 chambers with the first 2 in alignment and the 3rd chamber offset higher

Maybe there are different opinions on the origin of the word, but a quick lookup
