I provide below the function of the subterranean chamber in the Great Pyramid of Giza...
1) The chamber was used to create hydrogen. I am sure you know this but the hydrogen can be created with water electrolysis. For that you need to have water, terminals, and voltage potential between two, creating electric current. Hydrogen would accumulate around the negative voltage terminal (cathode), the oxygen would be around positive terminal (anode).
2) Hydrogen was important for the Great pyramid to function. See this video first for more details what the true function of the pyramid was. [youtu.be].
3) If you look on the picture below which shows the subterranean chamber (upper portion) you will see two hills. Those are two terminals. The limestone will work as terminals at high frequency electrons passing through.
4) The top view of the chamber (bottom portion of the picture) shows lots of similarities between terminals (like the base is about the same size, division between two is exactly in the middle, etc), but there are also differences. They are intentional.
5) Note that the terminal on the left side has wider area compared to the terminal on the right side. What it means is that electrons passing from the bottom up toward the king chamber will tend to pass through the left terminal, rather than the right one (read about how the size and cross sectional area of the terminals affect impedance)
6) I attached a simple schematic here below (with very arbitrary numbers) with the only intention to show that the voltage potential between two terminals will be such that negative terminal in the subterranean chamber will be on the right side (cathode) and positive terminal(anode) is on the left side. Talk to electrical engineer about this if more questions.
7) Now, if you look at the picture of the chamber, you will notice that the left and right shafts from the chamber are not leveled. The Hydrogen is lighter than the air, so it will be filling in the chamber and passing through the shaft on the right side, the Oxygen is heavier than air and will be passing through the shaft on the left side. Read below what forces the gas to move.
8) I mentioned that electrons passing through the caves and water will be subjected to Lorenz forces, lots of trembling will be there acting on the water, there will be also gas. So, the gas will push the water from the hole in the floor to the chamber. This will not be a steady process of water slowly pouring out of the hole, it will be process of gas and water blasting through the hole in cycles. It will be lots of action there.
9) Notice that the granite slab on the floor is oriented with the edge pointing straight and two flat surfaces pointing toward the terminals. I think the purpose of this slab is really increase pressure at the outlet for water and direct the water toward terminals. The water would blast from the hole toward the terminals, bouncing from the flat surfaces of the slab.
10) The gas coming in through the floor hole shall come out from the chamber, so it will push the hydrogen toward the descending package on the right and oxygen through the left shaft. The left side shaft is nothing more than the vent shaft to vent oxygen outside the pyramid.
