I don’t, but I can assure you it would be better as fuel than throwing water on the flames.

Oxygen isn't a fuel , but combustion isn't possible without it .

Well I would not let you loose anywhere near my steam engines.They explode because the vapour pressure exceeds the capacity of the boiler, with the energy coming from an outside source. There is certainly no energy generated from the steam boiling, and it actually consumes energy in doing so.

Given my degree majored in chemistry and was from an institution founded by the inventor of the steam engine, I’d like to think I know what I’m writing about.

True, but a non-sequitur. A diesel charcoal engine has plenty oxygen from air. And plenty exothermic reactions take place without oxygen too.

Wouldn’t want to.

Yes. You can dissolve salt in water and it will warm it up, or use one of those dinky plastic bag hand warmers.
What was the question .

Dont think you would get a job at BMW either with logic like that.

Sigh. The water injection system takes energy out of the system, and in the process cools the engine and hence allows it to run at a higher tune/ more efficiently. The water does not provide any energy, but takes it away.

Only given as an example of the potential of water injection but in the case of charcoal slurry the benefits are iin flash steam.

John, steam doesn't burn. It's already in its lowest energy state: (in simple terms) the oxygen and hydrogen atoms released the potential when they formed the water molecule. It might help to keep the reaction under control by adsorbing excess energy, the flashing to steam might even help to disperse the carbon in the charcoal, but it certainly doesn't add any extra joules, and will actually take some away by virtue of being hotter when it leaves than when it came in.
Don't just take my word for it though, find any high school or above chemistry student and ask them.

Seems your the one who needs to go to high school. Thimgs dont need to burn to produce energy. I will stick with the chemistry of charcoal and water being used in a diesel engine to produce electric.

That what I wrote earlier ffs. In very simple terms, the charcoal burns and gives energy, and the water boils and takes some away, but facilitates the charcoal reaction in the process. Don’t even try to claim you understand chemistry though and suggest that water reacts to release any energy, because you obviously don’t and it doesn’t.
And with that, I’m going to leave you to embarrass yourself alone - you don’t need any help from me.

Fimally you admit the steam cycle exists. Now we just need the admission that its the expansion of the water that makes the diesel engine turn or are you saying the diesel engine would turn on pure charcoal.

I’ll try once more, and then someone else can try to teach you basic chemistry. The water/ steam is the transfer medium, and whilst steam generation is indeed the way that the heat from the charcoal is used to make work, the water does not burn, does not transform into hydrogen and oxygen and does not undergo any chemical transformation. In fact, it actually takes energy away from the overall process in doing that job.
So please stop trying to pretend that the water is a source of energy as nothing could be further from the truth.

Maybe a spell back at Uni will do you good. In particular the advances in the knowledge of gas shift reactions and there use in modern coal and biomass plants for producing synthetic gases. Anyway I have already wasted to much of my time I will just have to agree to disagree.

I’ll go back to uni (PhD ?) when you learn schoolboy chemistry. Until then, you keep living in your world of make believe and misunderstanding.

Argh.
@renewablejohn - where do you think the energy is coming from in your charcoal slurry?
At the beginning of this tiresome interlude on an already bizarre thread I did say "useful energy" in respect of water. If you want to make hydrogen from water, which can then be used as a fuel, you will need to put some energy in. That's how an electrolyser works. There's no such thing as a free lunch.
