if oxygen were available it would immediately combine with hydrogen and we would have water

to get the hydrogen, you have to chemically block the oxygen with something else, for example iron or carbon

water costs nothing we don't care:

iron is expensive: you really have to see it as a machine to transform iron into hydrogen

and what becomes of iron oxide? swallowed in dust by the engine: iron oxide is abrasive ... not good for the engine

it is therefore better that the decomposition of water on the iron does not work too well!

Since the efficiency of the engines is far from Carnot's maximum, any modification, even at random, like adding a little water, has a XNUMX/XNUMX chance of improving as much as reducing the efficiency of an engine with very complex combustion.
So perfectly possible to improve the yield a bit, depending on the chance of the conditions.
But you have to measure with precision, a measurement rarely made by just looking at consumption over hundreds of km, under conditions never the same.

A priori, dissociate the cost steam water from the energy which is fully recovered by reforming it by burning the H2 and 02 formed.

So no change in the overall energy balance, if not too much water, but the change in combustion conditions, less violent can be, can improve the performance, with luck, as much as decrease it with bad luck, for combustion very complex (turbulence with chaos, full of more or less rapid and complete chemical reactions, etc.).

With the oxygen we breathe, two thousand times rarer than sea water, they are still on earth only thanks to life, which has preserved the good conditions for our life, over 4 billion years evolution !!!

Otherwise, as on Mars and Venus, there would be no more water in the oceans.

Isn't these disputes soon over?

I know it is not a fuel.
What I would like to understand is why the burner does not
does not go out when water is added to it. I know from experience that
without a minimum temperature or if it is too cooled the burner
goes out.
What I would also like to understand is why the burner seems
be stimulated when water is added to it.

water is not a fuel but when the water is vaporized it makes a violent agitation which can have some effect

for example a fryer at more than 100 ° C, set it on fire: it makes a large flame not very dangerous, just put a lid on it to put it out ... put water in it, it splashes oil on fire in all directions, and ignites everywhere: water does not provide additional energy but does cause a violent reaction!

I didn't understand how the video thing worked

if there is a certain amount of hot oil at the bottom, it is not surprising that putting water in it makes a reaction which activates combustion ... that does not mean that water is a additional fuel

otherwise ... air is a fuel! with my coal forge when I operate the bellows the more I blow the more it heats up! so air is good fuel

in the same genre the wind is produced by the movement of the tree leaves ... the proof when the tree leaves do not move there is no wind ... and when the tree leaves move it there is wind

Very simple!

Vacuum the water with a vacuum vacuum wrapper and you will see this water boiling and emptying of its excess oxygen, when you throw water on the fire, this same oxygen expands by the great heat beyond its boiling point and feeds the fire like a blower by increasing the combustion temperature.
