The Dendera 'Light bulb'

[DPKing]

Not to mention they weren't found in Egypt, and they date to WELL into the Roman era.
The Romans mysteriously didn't know about batteries in a kingdom they themselves controlled and occupied.

But somehow they let the solar gear machine slip through their fingers, we wouldn't rediscover the gear tech for another thousand years.  Not to mention burning that library in Alexandria, makes you wonder what was going on back then

There is ONE aspect (a single differential gearing arrangement) of what you are calling "gear tech" that we didn't know they had that at least one Greek figured out.
"Gear tech," as far as I know about what exactly you mean by that term, was known well before the time the Antikythera Mechanism was built and known forever after.

Unfortunately for the Greeks, they never realized they could use gears to make machines that make more, and better, gears.
They might have never become Roman vassals if they had got their nose out of the superstition of astrology.

The epicyclic gears would not appear again for 1500 years according to the speaker. 

In general -  These precision-cut, hand-filed bronze components functioned as an early analog computer, tracking celestial cycles, eclipses, and calendars. This advanced technology predated similar geared clockwork by over 1,000 years

But either way, how did the Romans not make use of this advance gearing technology?  It would not be surprising that the battery tech also alluded them

He explains his point of view, that doesn't mean he is right.

I watched until he mentioned that mercury plasma "moves away from you" and that there are two kinds of charge.
That's hardly an explanation, it sounds more like throwing science-sounding words at the viewer.


What power source did the Egyptians supposedly use?

They stepped down voltage of lightning strikes using dialectic lime stone on the giza plateau

William Sosa discusses the type of power needed to make the plasma bulbs here, DC current wouldn't work

Was it only operational during lightning strikes? not sure

That guy is so full of himself he may be about to explode.

And everything he says sounds "sciency" enough to convince some people, but is mostly garbage.

PS: I only watched one or two minutes, I don't have time for videos.

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

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


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

The supposed inventor of the modern Haber process for ammonia, loved to travel to Egypt, and essentially ripped them off. They were several thousands of years ahead of us, even worse than the gear tech from Greece

As you say, there is some hand waving here and there, but I believe mostly has it figured out

Well, this one was at the bottom of the sea and was a unique object. Nothing like mass produced. Almost certainly one of a kind (or perhaps one of a small handful.)
Rome took Greece around the time the object was made. Maybe the creator died then.
The Greeks didn't do anything with it either.
Heron lived under Roman rule, invented the first steam engine, and to him and the Romans it was a toy.

It is clearly a snake.

With a snake head and all.

Coming out of a lotus flower.

Snakes in water, like among lotus reeds, are particularly dangerous to humans.

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?
Initially it was dismissed out of hand b/c it was so far ahead

 References to gears survive textually in the writings of for example  Aristotle, Hero of Alexandria, or Philon of Byzantium, though are not the oldest examples of gears being used. It was initially thought the mechanism was from a later period because of its complexity fine details it was thought were beyond the capability of the Greeks. Though work was done demonstrating the tolls they had available were perfectly capable.
