Questons answered. Thanks!

all figured out, thanks for the help

A reaction is occuring between the chemical and the water, the water is not exploding.
Your car would in effect be running on the chemical and water; I assume that's more expensive than gasoline.

But if you could coat that chemical to the piston and make it stick and last for a long time all you would need to do till it wears off would introduce the water to keep performing the reaction, no?

High compression engine and no spark plug like a diesel, and use the coating and the water to produce the chemical reaction, or explosion, and push the piston back down and repete the process.

All the coating would be consumed in the reaction unless there was a barrier between each layer. If this was the case there would have to be billions of layers considering the engine runs at several thousand RPM.

but you are still "burning" the piston itself. I would imagine it would wear out rather quickly. what about residue in the engine? lots of mechanical issues. it's probably horrible cost ineffective as well. it can't be cheap to make those metals in purity.

I take it then a Alkali-metal is only a liquid form? If not a pistons metal does not wear down and that is what I am asking it to coat or make a piston out of this alkali-metal. It should always produce a chemical reaction till the metal wears away.

Maybe I am not wording this right?

Um.. really simple answer. It would be STUNNINGLY expensive. Metal >>>>>>>>>>>>>> Oil in terms of price.

No, you can have these things in solid form.

Maybe I'm wrong about the layers, I guess you could control the reaction by introducing a specific amount of water...

Regardless, the coating would only last a few revolutions, as it would be quite thin. If it was thick, or the whole piston was made of this material, the compression ratio would be screwed up as it eroded.

Even if you could make a coating of just the right thickness so that it lasts as long as a tank of fuel and doesn't screw up the compression (unlikely), then you would still have to take the whole engine apart every other day to recoat it.

That too.

The metal is not burning, the hydrogen from the water is. The metal is simply oxidizing very quickly which causes a lot of heat which in turn ignites the hydrogen.

Oh well it was a thought. It was just guess, that, like a diesel engine it wouldnt take much water and could do it at super high compression. As for the engine, if you made the oil pan unobstructive and removable quickly it wouldnt be that hard to pull pistons in and out, or something that you could pour into the intake at the end of the night to re-coat it all for the next day. It was just a thought after seeing it react that way with water, thought if you could just coat a metal like that to always act that way when water is introduced you could put it in an engine and then it would run off water.

After reading this thread and the Inconvenient Truth thread I have concluded that funboy42 is a certified retard.

Do you feel better now? Feel real big all the way over there in front of your computer screen do you? Since when does a person asking a question make them a retard? I had a question I knew nothing about, its how you learn
I guess all that go to school are retards

Hmm, there's also the issue of all the strong bases you'd form in the reaction with water.

e.g. NaOH, KOH, etc.

Also forget Fr, as it is nearly impossible to get pure. Cs and Rb are deadly expensive as well to buy in a pure form. There are much more efficient ways to generate hydrogen.

I wasnt sure, Im not a chemist, hence why I asked. I thought there had to be a few and I appreciate the few that took my question serious and give me serious answers.

LOL..

You clearly don't understand the nature of the chemical reaction.

It uses both substances in the reaction. You would effectivly be burning your pistons for fuel.

Generally not a good thing, if you want your engine to last for more than a few thousand revolutions.

No, I dont, thats why I asked

 

[Mo0o]

you do realize the metal itself is used up in the chemical reaction right?

 

[Dark4ng3l]

I agree this thread is retarded. Also I think the metal would combust when exposed to oxygen in the air too.

Not to mention that Francium is radioactive

But yeah, short answers:

1. Too expensive
2. Your pistons would get eaten up in 20 revolutions
3. Your exhaust would be highly caustic
4. Alkali metals are highly reactive and not found in pure form in nature. You have to put in a lot of energy to electrolyze them (I think you can get sodium by taking regular old salt, heating it to over 800 C so it melts and then electrolyze it... lots of energy)

I didnt when I made this thread, but I was shown the answer I needed over a hour ago.
