Here's the interior, roomier than in looks in the diagram. Space to sleep, the exercise, to use the shitter and to fish through the moon pool. The whole thing was actually built from a repurposed cargo container.

great idea for a new prison

Here it is being sunk, the struts are to keep it high enough off the bottom that he can swim in through the hatch underneath. Not seen; the pre-sunk concrete ballast.

Well aren't you a ray of sunshine?

Here's Lloyd's second habitat, BioSub 2. It was situated in the Legoland Germany aquarium for two weeks as a demonstration of feasibility. Visitors could talk to him via microphone setup during visiting hours.

Here's BioSub 2 being lowered into the massive aquarium by crane. It would be Godson's home for the next two weeks, containing all his food, changes of clothing and so on.

I'm still waiting to see the results of Project Hampture before I get my hopes up on undersea living.

Good quality pics OP. Thanks.

Undersea living sounds awesome, except for the fact that you would be completely cut off from the rest of society for no reason other than "its cool".

Shaun Waterford is following suit, with a monolithic concrete dome design that uses a proper two-door waterlock to permit divers entry. He's partnered with a concrete dome company interested in supplying the materials so it's not strictly a one man job, but it's also greatly more ambitious; Shaun intends to stay down for three months, using plants to generate the oxygen.

who do i talk to to reserve my home in rapture?

The only advantage I could possibly see to this is regulated temperature.

>>2247965

What does the diagram mean by "recycle waste and urine"? What sort of magical box is this?

>>2247996

>>I'm still waiting to see the results of Project Hampture before I get my hopes up on undersea living.

The Mk.II habitat was a great success! See for yourself: http://www.youtube.com/watch?v=05pkg0DuPNQ

Currently I'm having an associate assist me with the Mk. III habitat which has 4 rooms, an exercise wheel, and a clover grow-op.

>>2248023

>>who do i talk to to reserve my home in rapture?

Dennis Chamberland, head of the Atlantica project. He's an ex-Nasa engineer currently building two interlocking undersea homes to be tested in the gulf stream sometime in 2012, pending the establishment of a permanent civilian colony in 2014. Anyone who wishes to join needs only buy their own module (two beds, kitchen, bathroom, LCD tv, $35,000. Pic related)

>>2248012

>>Undersea living sounds awesome, except for the fact that you would be completely cut off from the rest of society

Not seeing any downsides...

yeah but how do they get in and out of that hole in the floor without flooding the place?

>>2248012
You realize that you can just surface and take a boat (or swim) back to "civilization," right? It's a bit like living in the country.

Godson's eventual goal is to station Biosub 3 deep underwater, off the Great Barrier Reef of Australia and rent it to oceanographers and marine biologists who want to use it to conduct extended studies of the reef, scuba diving 8-9 hours per day for several weeks without surfacing.

>>2248069
Air pressure keeps it from flooding. So... you go in, and you go out, and the worst you get is a puddle on the surrounding floor.

>>2248069

Hold a glass upside down and force it down into some water. See how the water level in the glass stays the same because the air is trapped? Like that.

Honestly, /sci/. Are you even trying?

>>2248069

the air pressure inside is equal to the water pressure trying to get in.

Same reason you have an air-bubble in an upside-down glass underwater.

>>2248070

>>You realize that you can just surface and take a boat (or swim) back to "civilization," right?

Well, you need to undergo decompression if your little home is deeper than 25 feet. The only alternative is to keep the interior at a constant 1.6atm like the surface, which means using a double door airlock to get in and out, like this design: >>2248016

The civilian colony will be 1.6atm so that people don't need to wait 18 hours to decompress before surfacing. That is the number one fear associated with this lifestyle, "being trapped"

>>2248093
seems interesting about how much does one of these home cost?

Personal subs like these can be had for $7,500, although you could build one that encloses your whole body for about $10,000. There's a whole association of amatuer minisub builders, even bi-annual races. It's something technology has made it possible for a man of reasonable means to accomplish.

>>2248104

>>seems interesting about how much does one of these home cost?

Heh, that's just concept art. This is what two of the actual home modules look like interlocked, using the universal docking hub.

>>2247978

thats the first thing that jumped into my mind

Why are underwater buildings always yellow?

>>2248114
Visibility would be my guess.

>>2248105
that is pretty cool looking but i would like to know how much a living space would cost

More cool concept art...

I actually plan to build something similar to Godson's Biosub someday, but out of a water storage tank (of the sort hauled by truck). You can usually score them for a fraction of what they cost new at scrapyards, they're already the right shape to withstand water pressure, they're spacious, and they can be hauled to the local boat ramp via truck.

That is, if Chamberland's modules don't wind up offering a better value for the price.

>>2248113
lol same here my first initial idea to

>>2248055
Being cut off from society includes being cut off from the internet and all communications, as well as all supplies like food and media. You also wouldn't have any income since you couldn't work any job.

Starting to see the problem?

>>2248120

>>that is pretty cool looking but i would like to know how much a living space would cost

See: >>2248049

$35,000 for a two person unit. It's about as spacious as an RV. Here's what the inside looks like.

Hey OP, what kind of detrimental effects can living underwater have on your health? Do you have the same risks as when you go scuba diving?

>>2248127

>>Being cut off from society includes being cut off from the internet and all communications,

Satellite internet equipment on the surface buoy provides connectivity. There's also the possibility of a direct radio uplink to a shore station for cell phones and internet.

>>as well as all supplies like food and media.

You're surrounded by free biomass. Historically aquanauts have supplemented their diets by trapping fish and crabs who are naturally attracted to the habitat because of the lights, and the structure which acts as an artificial reef. Easy pickins.

>>You also wouldn't have any income since you couldn't work any job.

Telecommuting.

only 35,000 and thats not half bad it would be one hell of a vacation home awsomes

>>2248127

Float an antenna.

>as well as all supplies like food and media

Those you would have to get for yourself or have delivered, just like, you know, on land.

>You also wouldn't have any income since you couldn't work any job.

You could work from home, commute by boat, work under the sea, or be rich enough for this not to be a problem.

You're acting like this is deep space. It's not.

>>2248145

>>Hey OP, what kind of detrimental effects can living underwater have on your health? Do you have the same risks as when you go scuba diving?

Well there were a number of hazards in the 60s back when were were basically making up the rules as we went along. Early aquanauts found out the hard way that living in a high pressure, high humidity environment directly exposed to sea water was an invitation to constant ear infections, and to a constant slight euphoria due to the helium/oxygen breathing mixture necessary at that depth (as ordinary air becomes toxic under that kind of pressure).

The solution? Build habitats to maintain 1.6atm, surface pressure, and use regular air. A diver lockout (Sort of an airlock) and docking rings for passenger subs replace the moon pool, preventing the spread of humid air. Little things like this and triply redundant dehumidifiers have corrected all of the issues with undersea living thought to make it impractical back in the 60s.

>>2248153
What exactly are you looking for? What's the point of a house?

>>2248155

>>How's project Hampture going anyways?

See: >>2248035

The Mk. III is finishing construction, and waiting for warmer weather.

>>2248153

>>what's the point?

What's the point of living in the mountains? It's also impractical for its own reasons. What's the point of living in the desert? What's the point of living in the woods?

Some people prefer those places. And modern technology permits them to live there comfortably, so they do. The ocean is beautiful, and full of free food. What's not to like?

>>2248167
you say back in the 60's... were they considering or researching using these as bomb shelters or radiation shelters in the cold war?

why are you guys saying 1.6 atm is surface pressure? surface pressure is 1 atm, just one

>>2248206

>>you say back in the 60's... were they considering or researching using these as bomb shelters or radiation shelters in the cold war?

No, they were considering them for keeping crews of divers on standby that would be adapted to very high pressures so they could be carried to the sites of sunken Soviet subs where they'd recover warheads. Declassified documents reveal this was successfully done at least once.

>>why are you guys saying 1.6 atm is surface pressure? surface pressure is 1 atm, just one

It's the pressure at about 21 feet (head level. It's why habitats for tourists are at about 25 feet). That's the greatest pressure you can live under for prolonged periods and not require decompression to surface. It affords the structure a bit of extra support against the exterior pressure as well.

Basically 1.6atm is the magic number, the pressure we can comfortably live at, breathing a normal air mixture and surfacing whenever we want without suffering the bends.

Some examples of jobs you could perform for a living without ever surfacing...

>start colonizing the ocean before we get our shit together
>100 years later, the ocean is dead

COOL STORY BRO

FUCK YOU HUMANITY AND YOUR FUCKING TECHNOLOGY


DEAL WITH IT

>>2248269

>>100 years later, the ocean is dead

On the contrary, oceanic colonization will improve the ocean's health for these reasons:

#1. all undersea vehicles are electric and charged from solar buoys, therefore zero emission

#2. Any metal structure underwater acts as an artificial reef. Coral loves growing on steel for whatever reason, it's why we sink old ships to serve as reefs.

#3. We can actually grow new modules out of "biorock", a dense type of coral which forms at an accelerated rate around electrified wire 'skeletons' shaped like the desired final product. See pic.

#4. By farming the seafloor using surface methods (As seen here >>2248270 ) we increase the output while eliminating the need (and justification) for trawling.

>>2248203
Shit, it would be so awesome to wake up in the morning to see a grouper staring at you out the window.

Out of curiosity, how much cycling did he need to do to power the Bio-coil and lights?

hey op, im curious about the amount of corrosion sea water has on metals that would be used on a wide scale.
replacing components constantly just doesnt make it seem feesible

>>2248291

>>Shit, it would be so awesome to wake up in the morning to see a grouper staring at you out the window.

"Get in here so I can eat you"

>>2248295

>>hey op, im curious about the amount of corrosion sea water has on metals that would be used on a wide scale.

This is why many habitat projects were permitted to 'grow over', such that they formed their own thin skin of coral and other growth that protected it from corrosion.

We also have new materials not available in the 60s that do a much better job of protecting against corrosion.

>>2248294

>>Out of curiosity, how much cycling did he need to do to power the Bio-coil and lights?

He was cycling basically any time he wasn't asleep, eating or shitting. Cycle powered is not the way to go.

For a more satisfactory answer, and probably what you were really getting at, using centrifugal sea water separation it takes about 150 watts per person to supply fresh air to an undersea enclosure. Pic related, the separator mechanism. Here's how it works:

http://www.likeafish.biz/

Who wouldn't want to live here? Mind your neighbors though. One of the obvious uses for these little modules would be transient locations for illegal activities to take place. That's acknowledged in his book although he affirms that it's not his concern what people do with them.

Hey, I remember this thread. Last time everyone pretty much agreed it would be the best way to grow pot and not get caught. Good times.

Here's a small underwater 'clubhouse' built by a family of diving enthusiasts. Notice it's an inflatable design, using transparent sheet plastic (vectran I believe) under a nylon net, secured on all sides to an octagonal steel frame. It's anchored at all 8 points to the sea floor with weights and the air inside is refreshed by scuba tank. The consumer version has no net (it's one contiguous 'bubble', made of strong enough material to withstand the upward force by itself) and the air is refreshed by a supplied electric air compressor which releases fresh air into the clubhouse via "O2 bubblers". Stagnant air is, as with all moon pools, forced out the bottom.

Here's one of the divers inside the 'bubble room', which they now offer as a standalone product to anyone interested.

This is really a novelty product but it has me excited about the possibilities of inflatable underwater structures. That seems to be the way that space habitats are going, so why not also undersea habitats?

i remeber reading about this under water ship being built that use this type of gas/magic to use a kind a bubble to keep the water away from it also there would be no restaints so it could travle a few 1000's miles per hour under water.

any one else read about this?

>>2248405

Yup, "supercavitation". The 'underwater warp drive'. The upper known limit is 300mph however, and the prototype fast attack sub being built now will do only 115mph.

>>2248478

I think I'd get tired of sea food after a while.

It's a beautiful place to live, isn't it? The radiant blue glow, the gentle haze in all directions, the soft white sand underfoot. It's like another world. It's so far removed from our everyday experience that it may as well be. But in 2014, we'll go there not just to dive or survey, but to live, work and play. We'll become homesteaders on a new frontier.

Look at that view. The sand beneath his feet, dotted with swaying plants. The blue glow he's bathed in. The sun shining through the shimmering waves overhead, like a second sky.

>not a scientist, just an avid diver

doesn't compute

Posting for possible zombie apocalypse safe house. If the habitat was high enough off the sea floor one would be completely safe from zombies. Food would be a problem unless one had scuba gear to hunt for fish; however the scuba brings its own issues. One would need to run an electric compressor using the bike to fill the tanks with oxygen. It may be doable, but I foresee some hardcore technical difficulties for anyone who tries to design something like that in his or her own garage.

>>2248896

>>It may be doable, but I foresee some hardcore technical difficulties for anyone who tries to design something like that in his or her own garage.

Lloyd Godson did just that. So did Shaun Waterford. And I intend to try. An undersea living space isn't so complex as it seems.

>>2248903
They built a bike powered compressor that can fill usable scuba tanks?

Op,

What is the name of the diver who came up with this concept?

>>2248912

Nope. The bike charged batteries, which powered the lights, which drove photosynthesis in the algae biocoil, which provided fresh air.

See the green thing in the background? That's the biocoil. The second best way to produce fresh air underwater.

>MFW aliens have been living this way under the earth's ocean for millions of years.

>MFW humans come along and fuck up the atmosphere by living above ground.

>>2248927
*grumble*
I wasn't talking about that. I said it would be difficult to run a compressor off the bike to fill the scuba tanks and be completely self sufficient using the fish in the ocean as food.

>>2248933

Right, but the biocoil setup is entirely self sufficient provide you cycle everyday and use stationary traps outside to catch crabs, shrimp and fish. You'd need a source of fresh water, however....

>>2248944
OH! How about a shortwave radio with a antenna buoy!

As for the water problem, one can desalinate ocean water, it just takes some energy to boil the water. That wouldn't be possible with human power, put perhaps with some wave-energy electric generators it would be possible. Simply float some barrels near the surface. The changes in pressure as the water goes up and down should give substantially more power than a bike.

>>2248930
anymore sweet gray-model pics like that?

and what's the point of this bullshit? is it surviving a nuclear holocaust and hiding from brain eating zombies?

enjoy your schizoid paranoia, underwaterfags

The technology used in these kinds of things interests me but I don't see the point of living underwater.

>>2249105
because we can

>>2249105
When we run out of room on land.
Yes, this will eventually happen.
Which is why I suspect Japan, China, and the like will be the first to utilize large scale operations of this type.

Undersea living is like space living, except with gravity and a fish going by every now and then.

Honestly why would you live in a fucking 5x5x5 prison like this. This looks more like vegetating than living.

>>2249122
we build skyscrapers, you waterfag

and the populations of civilized countries are shrinking anyway

>>2249202
Or floating/hovering/flying cities. Or orbital space colonies.

Also the populations of those countries will level out fairly soon, they're hardly going to die off. Case in point is Russia, its population is predicted to stabilize around 2050.

Couldn't he just have a hole under the toilet? The sea doesn't mind if you poop into it. Fish do it all the time.

>>2248973
nobody boils salt water nowadays (at least not if you don't have the sun available to do it). The way to go is reverse osmosis and/or ion exchange.

Wouldn't the depth-restriction on these be limited to 30-40 feet though?

Any deeper and you are going to get narc'd

>>2247965
Enjoy the massive earthquakes, ocean faggot.

>>2249328

Uh...what?

>>2249310

Nope, that only happens when breathing gas that itself is under pressure. At the bottom of oilrigs they often have underwater habitats for divers who spend weeks at a time underwater (will try to find source), they do not have this problem because they are not breathing with regs.

>>2249577
this is true. Free divers can descend 60-80 meters in seconds because they aren't breathing from a tank.

So you catch fish. But then you have to cook it. Yeah I like sushi, but really, most of the stuff you catch or harvest you'll have to cook.

>>2248012
Perfect for escaping the zombie apocalypse, though!

>>2248049
Shit, I got $35k right here! I was going to use to to build a cabin on the ranch I just acquired, but this may be a better use of the money.

seaQuest, here we come!!

It is actually a great idea for new prisons.
Its cheap, and with an atached fishing space it will be completley self sufficient, we could drop them deep in the ocean to stop criminals from swimming out.
We could make a castle of them, all attached to house hundreds of prisonsers
with anti-magic locks and wraiths to stop those pesky dark magicians from escaping

We could call it Askaban.

>>2250045
This basic idea was already tried. It was called Australia.

>>2250051
That's were the British failed, They forgot about the broomsticks and that dark wizards could fly, That why the LeStranges got outand that other dog guy.

Can sharks and stuff get in?

Also, I don't think the big companies will allow this due to the massive amount of waste dropped in the oceans.

We should grow weed in them.

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.

>>2250299

>>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.

>>2249171

>>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:

>>2250073

Agreed. /Sci/ needs an underwater weed ranch. For research.
