I wanted to cool down the steam from a geyser, and by accident figured out how you could cool down the water down to sub-zero degrees in the process.
The water does not break pipes, even though it is below freezing point.
I call it a Carbon Bubbler
Basically it cooles down CO2 down to the point where it liquifies, the liquid CO2 then drips down into the water tank, cooling it rapidly and in the process becoming a gas again, while cooling the water in it's decent to the top of the tank. At this point it becomes a rinse and repeat kinda thing.
The liquification of the carbon dioxide is so rapid, that it creates a vacuum at the end of the chamber for extend periods of time, This again helps with drawing in more Carbon Dioxide.
I hope someone else can use this, it seems quite strong given i only use 3 weezes to power it.
Water is used for oxygen and toilets + wash sinks.
I'm unable to figure out how much water i actually use on the oxygen generation, But maybe someone smarter then me can do the math ? - in case this is of interest for someone.
