and u only delete my pousts i feel targeted by you 
You were replying that there coulnd’t be air filled rooms, but the post you were replying specifically said it wasn’t needed. So you weren’t replying to their arguments
We aren’t using fire, we are using heat escaping from vents which means no oxygen is required. There would be a room build around the vent to keep the heat from escaping letting the inside acquire the temperatures needed to melt the metal (a forge). I think I proved underwater civilizations are possible but I know someone is going to find something I missed and need to find an answer to.
Until then VICTORY
what he sayd
he says that he is going to trap the heat
water can onyl heat up to 400’C
so it must be air
but the vents eject waters
so he cant have air
understand?
aaaaaaaaaaah i feel like im fighting with flat earthers and a feminist is protecting them 
I also made the point that you can only melt lead with the amount of heat that comes out of vents. AND I moved the discussion forward about having useful technology made from the metal
where?
In the thread
“Being able to melt metals with a low melting point into simple tools is far away from developing the technology --”
Also your point about requiring air to heat over 400 degrees would be more effective with the fact that you can’t use 400 degree water to heat air above 400 degrees without some heat extraction machines
ok but why use lead in stead of coral?
lead is a metal?
And the point was melting metals, not coral?
ok but the cost of a lead tool will be alot
