If this structure would be lowered into water with normal air pressure inside the box the water would compress the air a lot and water would fill most of the space inside. To keep the level of water at a level of 10-15 % of the height of the box it wouldn't be possible to lower it more than about 1.8 meters with normal air pressure in the box. Therefore, there is a over pressure inside the box and more air had to be filled into the box as it was lowered down to the bottom. By increasing the pressure of air inside the box it would also keep the box from imploding because of the surrounding water. A human can survive at a higher pressure, at least for a while: "Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet." ([link]) Imagine that it's not as deep as 500 feet. Rather a few hundred feet's or maybe less, but that is not really important.
To get food he has to fish, which you notice if you look closely. The small propellers provides the lamps with energy. The water is moving and makes the propellers spin.
The big failure will probably be that the air runs out as it would require a lot more trees to keep producing enough oxygen to keep him alive. Slow death in the aqua custodia.
I actually did this once though. It was in Minecraft..... lol
Did you you know It is estimated that marine plants produce between 70 and 80 percent of the oxygen in the atmosphere, maybe put some sea weed around the house in the water
"aqua custodia" is a reference to jacques cousteau?
(hope i spelled his name half way correct)
(I don't know If I write this in the correct way).
Riktigt bra jobbat, har du den högupplöst så skulle jag gärna vela ta mig en ordentligtitt på den . Du kan få vattenmärka den om du känner för det.
Very well done on this piece, great attention to detail.
really bizzare and original work!
Especially the bottom of the "aqua custodia" connected to the sea is a intriguing idea.
but the trees need sunlight in order to make photosynthesis, and the level of sunlight passing through the water decreases dramatically when you go down deeper. ıf the needed light is provided by the self-generated light sources then it means there is not enough sunlight to lighten the underwater-glass-cage, and trees can not be able to produce oxygen, instead like in an endless night, and they will increase the level of CO2 in the cage. So, i guess it is more efficient and possible to use the seawater itself to distill oxygen. may be mirrors can be used to bring the sunlight to the deep sea (like the Japans did for growing tomatoes in metro stations). Also we do not use pure oxygen, it is just the 21% of the air, the other components have to be existent.
These are not for saying that it is impossible; these are mind-itching problems that probably have solutions if we pay attention more.
may be it is hard to make a closed-circuit habitat for a single human and single unit, but it is still possible i think.
to sum up (I've talked too much) ; the idea is good and i liked the result, but it needs some improvements to become more liveable.
