Q - At what pressure does hoh gas collapse under pressure. It is reported to be around 80-100 PSI. This video is an attempt to find out. Here we close the ports on a hohcell, fill with electrolyte then apply a charge and wait...Find out what happens!

What do you mean by having the gas collapse on itself. That makes no sense. The gas will either self ignite if the pressure reaches a certain level or the cell will burst. Self ignition is not collapsing on itself... Please clarify.

Hi blakers24, if you think about it, water occupies a much smaller space than gas, so the only thing it can do when the HOH gas converts back to water is collapse. The question still remains at what pressure this occurs. We see this collapse regularly when we ignite the gas in a sealed environment. The net result is a vacuum.

interesting -pity the cell burst

[hohcells]

Indeed. Though 90 PSI for the cell is good going, which is well over it's 10PSI opperating spec, it would have been nice to get it to at least 160PSI. Any info on the actual collapsing pressure would be appreciated, just so we know what to aim for next time. May prove out of reach?

think i might know someone with the gear to test this....

[hohcells]

That sounds great. May have organised something too. Hopefully over the next week or two will be able to provide an update.

Thank you showing this. I have seen similar here. My own cell designs have not been able to stand more than about 60 psi before my gaskets give way. However, I have put a fair quantity in a sealed tube then applied a compressor up to 120 psi without the gas reaching the self ignition point. It is interesting that the gas becomes more conductive as more pressure is applied. But suspect a lot more than 120 psi would be required to auto ignite.

@fuelban No hydrogen will not self ignite when mixed with oxygen until it reaches 550 degrees. Until that temp it remains stable at any pressure, that is why you cannot start a cold diesel truck on hydrogen.

I dont understand, I was able to build 2500 psi in my cell with no issues. It did this in less then 5 minutes. They also use hydrogen in high pressure experiments because of its make-up. It will go back to a water state when it cools down and not under pressure.  Very similar to air conditioning.

AT 90 psi, THE SEAL BLEW DID IT NOT !. I don't think the gas will explode under pressure due to pressure its self, it becomes a liquid does it not, but you need to keep low temperatures, its the act of compression generating the friction / heat, that causes combustion, not pressure in its self.

This is nonsense. Go back to school and try this time to get a real education.

@blakers24 in other words, HHO implodes not explode

[MichaelCouch]

Self ignition is dependent on quality of the gas and vapor content. Without knowing how you cell is constructed one can not tell the quality of your HHO.

interesting researchthank you for sharing it so far.
