Maybe ... maybe not ... I saw some things that didn't add up for me ... so I figured the best option was just to ask ... that way he can tell me what step I missed or detail I missed , to get his final system pressure numbers.

All the previous points made do still stand ... it takes energy to raise room temperature water up to the phase transition point ... and it takes more energy to actually do the phase transition.
All that energy has to come from somewhere ... it isn't free and there are pros and cons ... the pros are fine , but one should be aware of the cons as well , in order to form as accurate and balanced an understanding as possible.
Yes a steam engine works well with the expansion from the phase change of the water ... but that is significantly different than just injecting liquid room temperature water into a ICE that was not designed for it.
