>damn i did'nt think any one cared that the ocean is turning acidic and going to die. thanks so showing me some hope OP

They've made great strides too. Methods ranging from manipulation of herbivore diversity to artificially accelerating coral growth with electrical current have proven effective, but the implication is that coral reefs will need to be on human designed life support until we can get oceanic acidity back under control

Well, in ocean water you can cause minerals to accrete rapidly on any electrified surface. This is called biorock accretion. If you could finely control which parts of an object are electrified at any given time, you could build geometrically precise objects out of an oceanic mineral substance harder than concrete over a year or two.

It's a bit like low tech 3d printing using a substance that surrounds you in the ocean.

Here's an illustration of how biorock accretion works.

>>No breaking of coral barriers please.

On the contrary, we can build undersea homes by artificially inducing rapid coral growth over a skeletal metal dome electrified from solar panels. See pic.

Combine that with the fact that even metal structures sunk in the sea gradually act as artificial reefs, and all subsea vehicles are necessarily battery electric, and you have a formula for a frontier colonization effort that will actually improve the natural environment it moves into.

>>So what happens when it becomes dislodged from its deep foundations and hurtles to the surface with you in it? surely all that expanding air cannot be good.

If it's at 1.6atm, nothing happens. That's why minisubs can surface without waiting to decompress, too. You only need to decompress if you've been subject to the outside pressure for an extended period.

>>Honestly why would you live in a fucking 5x5x5 prison like this.

Why would you live in a log cabin on the prairie instead of a high rise apartment tower? Because that was all they had at the time. Same here, these are the first few people settling a new land so the accommodations will be fairly spartan. But as the colony grows and corporations add their own business modules to make some money off the inhabitants a local economy will develop that will make it possible to build larger and large modules. Probably using the biorock accretion method outlined in this pic:

>>Sea warp engine...next is the space warp engine...

Ocean exploration is basically easymode space exploration. It has a lot of the same technologies, scaled down.

For instance, you know how many spacebros hope for nanobot assembled space colonies? Seabros have something like that already:

tl;dr you can build a wire mesh in the shape of a habitat, then electrify it, and over about two years "biorock" will grow to completely envelop the mesh and form a shell made of incredibly hard accreted minerals and coral.

When it's done you can attach life support and move in.
