such is life under the sea

Here you go. :3

Have your hamsters drowned yet from the leaky habitat?

>>3335295

>>3335334

Ambient pressure habitats do not take on water. There's an overpressure of air inside that constantly leaks out, by design. Air can get out, but water cannot get in.

>>3335348
oh yeah i remember, the pump. then what's the point of having algae for oxygen if you already have an air pump connected to the surface? the O2 from the algae and the enclosure isn't enough to maintain ambient pressure.

>>3335459

The habitat is being deployed *initially* with surface supplied air. Then, later on, it will be switched over to algae based life support. They will not both be used at the same time.

why the fuck do you want to live in the sea??

>>why the fuck do you want to live in the sea??

Compare these two. The answer should be fairly obvious.

"Why would anyone want to live underwater?"

~Person who has never been underwater and seen how pretty it is

what if the line that carries the crane that picks the boxes up breaks

So you'd waste tons of money, starve millions of people in the 3rd world and waste the opportunity to invest in technology with far more potential just because "hurr it pretty"?

You're living in an air conditioned home, enjoying fast internet access and eating store bought food. All of that also occurs at the expense of the third world.

We cannot destroy civilization and return to the caves in the name of fairness.

white guilt bs

Then so was this: >>3335814

Problem solved.

Except the luxuries I enjoy beyond my lessers are due to the profit motive and market forces, what you are suggesting is we spend money not on education, equipment and training in China but on building some underwater city.

>>3335873

If an undersea community is populated by people who pay good money to live there, it is just as much a product of market forces and profit motive.

That kind of scenery only exist in shallow waters. Deeper into the sea, it's not so pretty.

Mad Sci, tell me everything you know about biorock

Could I sink a rebar and chickenwire structure around my 20 foot deep ocean house, let the juice flow for a couple months, introduce some coral and have a full, balanced coral reef around my house?

Not really. If a gamma ray burst strikes the earth, we're all dead if we don't have space colonies.

We need to focus on space for the safety of humanity. Plus those glorious resources.

Focusing on the sea is a curiosity.

Focusing on both at the same time however, allows us to develope the tech to live in both places faster. Same basic principals. Make air, don't have holes.

It requires the specific mineral composition of sea water to work but otherwise yes.

>>Not really. If a gamma ray burst strikes the earth, we're all dead if we don't have space colonies.

Actually water is an extremely effective radiation shield.

>>We need to focus on space for the safety of humanity. Plus those glorious resources.

80+ billion worth of rare earth minerals were just discovered on the ocean floor:

These are the specific metals needed for the technologies we require in the near future as oil runs out.

>>Focusing on both at the same time however, allows us to develope the tech to live in both places faster. Same basic principals. Make air, don't have holes.

Also true. Development of modular pressurized habitats, autonomous robots, advanced life support and so on are directly applicable to space exploration.

The resource wealth of the sea will provide the influx of wealth, minerals, food and energy that we need to expand meaningfully into space. It's not a cheap endeavor, and we need to fund while also feeding an expanding population and meeting its energy needs. The ocean is how we'll do that. It is the logical stepping stone to space.

If space is going to be our future, the ocean must be our present.

How dare you question Mad Scientist.

Love what you're doing Mad Scientist, good luck to the future and any other projects!

One day I am going to go and live in your undersea palace Mad Sci. Can all the woman be made to wear mermaid tails and swim around outside?

>>How dare you question Mad Scientist.

He's right, though. But misses the point. Yes, the shallow water is where it's pretty. But that's the point. That's where the resorts, hotels, restaurants, etc. are and it's where the first permanent living communities will be.

Right now, only one company makes an undersea home, and it costs several million. (pic related) But soon there will be cheaper, more modest options available.

Gamma ray bursts are very quick and are deadly because they're hard radiation, not because of sheer joules released(i.e. ~half the planet dead from radiation poisoning, not the entire planet dead from boiled oceans)

Nothing short of a collision with a planetoid or the sun going nova would sterilize Earth

what about fire?
