HHO Generation using High Frequency electromagnetic waves on water

[Sergh]

Strange parts in the Zografos device.
I can't classify them exactly. Although by the appearance of these parts it can be assumed that they are not homemade, but industrially manufactured
Help needed!

Who can identify these parts?

1. A black object with 2 thin silicone pipes entering from above. On the left pipe there is a non-return valve for the aquarium. At the bottom of the object you can see what looks like an adjusting bolt. But it is not exactly. I assumed it object as the pump. But not sure. Can anyone identify this object?

2. An object in front of a small fan. Something needs cooling. Visually it looks like a reel, in which 2 tubes enter from the end. The color of one of the pipes is yellowish.

3. The cone-shaped metal part on the jar is probably something from gas equipment. I saw something similar for gas, but I don't know the name and functionality.
Under it is a transparent container with liquid, it seems.
A dark gray-yellow cylinder with a lid is attached to this container. 2 wires are connected to it, which go to radio components, like a transistor and a capacitor or inductor. Doesn't look like a power circuit.

Yes, I made a similar antenna at about 22 GHz, because that's where one of the resonances of microwave absorption by water is located.

There you are.

Did they themselves come up with the idea that the frequency ranges of radio transparency are related to resonance?
In general, the resonance is usually determined by the maximum absorption of microwave energy.

So what about these frames from the Zografos video? Did no one recognize the type of devices used by Petros Zografos?

The devices look like factory-made.
