Source: NPR
Would it take more or less electricity to crack water under pressure or in a liquid or vapor state?

2$\begingroup$ Check this link: en.wikipedia.org/wiki/Water_splitting#Solar-thermal, how will you pass electricity through water vapors? $\endgroup$ – M. Farooq Apr 4 '19 at 13:11

$\begingroup$ @M.Farooq I want to say it could be done with laser filamentation. $\endgroup$ – Muze the good Troll. Apr 4 '19 at 13:54

3$\begingroup$ @MaxW I don't think it so, water starts to spontaneously decay at $\approx 3000 ^\circ \rm C$. Plasma state starts to appear at $\approx 10000 ^\circ \rm C$. Mixed $\rm H$ and $\rm O$ plasma will be a neutral mix, there will be too hot for any chemical binding. $\endgroup$ – peterh - Reinstate Monica Apr 4 '19 at 20:15

1$\begingroup$ @M.Farooq It is a nice answer stub, in my opinion. I think it obviously closes out any gaseous phase. But it doesn't close out fluid water in elevated pressures. The question is, where is the efficiency optimum. $\endgroup$ – peterh - Reinstate Monica Apr 4 '19 at 20:23

1$\begingroup$ I think this question has potential, but you should organize your thoughts better so that the question is more clear. $\endgroup$ – A.K. Apr 6 '19 at 1:40
