I regret not getting clearer pictures to zoom in and see the words on the instruments but I felt the need to be discreet as I was just walking by, these ocean-front home garages are rarely/NEVER left open unattended. What is this mystery chamber?

One more different angle picture in the comments, you can see the seating bench in the chamber.

In case anyone else was curious, looks like the most common use is for the rich to recover faster from the bruising and swelling of plastic surgery.

Dragon Ball Z-lift

It can also help with a lot of conditions like MS and ME.

That's definitely a hyperbaric chamber.

I did an image search for "hyperbaric chamber" and this place popped up in the first few results, and whatever chamber they're using looks very similar to that one, so it's likely from the same manufacturer https://www.facialplasticsurgeryofaustin.com/about/our-on-site-hyperbaric-oxygen-treatment/

Edit: specifically that's apparently a hyperbaric oxygen therapy or HBOT chamber

[–] Today@lemmy.world 7 points 1 month ago (4 children)

Could it be for diving decompression?

[–] jaennaet@sopuli.xyz 8 points 1 month ago

I guess you could use it for that too? And it's not like it's 100% guaranteed that it's only an HBOT chamber, since I'd assume you could use it with just air instead of more-or-less pure oxygen

[–] KeenFlame@feddit.nu 3 points 1 month ago

That is what they use them for. So yes.

[–] pineapplelover@lemmy.dbzer0.com 2 points 1 month ago

Yeah but you would like only use that for emergencies

Fuck me, I'm dumbfounded that people with billions would choose to live on a fucking main street.
There are more cars in that one picture than I see in a week. Christ.

[–] LemmyKnowsBest@lemmy.world 8 points 1 month ago* (last edited 1 month ago)

It's a few houses down from one certain house where JFK & Marilyn Monroe played hide the salami together, where also years later Paul McCartney & John Lennon were last together in the same place (or something Beatles last time something). Paris Hilton also had a house here further up the road before the January 7th fires consumed it. These homes are usually empty because the people who own these houses have several homes all over the world, so these are just an occasional beach retreat for them, an eyesore and ocean-view-blocker for everyone else.

Anyway my point is, it's a popular well-known area, right by the ocean, which means everybody wants a piece of it, both major highway & billionaire beachfront homes. In fewer words:

Pacific Coast Highway.

[–] walden@wetshav.ing 9 points 1 month ago

Would a billionaire live on a busy street like that? Maybe just a multimillionaire.

[–] athairmor@lemmy.world 35 points 1 month ago (5 children)

Personally, if I was a billionaire, I’d rather have a maid and groundskeeper than a hyperbaric chamber.

[–] crank0271@lemmy.world 75 points 1 month ago

If you were a billionaire you wouldn't have to choose. It's no longer "or," it's "and" for everything.

[–] scytale@piefed.zip 4 points 1 month ago (2 children)

And a personal chef. Not having to cook everyday is a privilege.

[–] rainwall@piefed.social 5 points 1 month ago* (last edited 1 month ago)

They aren't everywhere, but there are "meal prep" companies that work out of local commercial kitchens and deliver full weeks of meals to your home.

Not as cheap as making it from a scratch, but cheaper than hello fresh and others, and much cheaper than uber eats.

[–] Aeao@lemmy.world 3 points 1 month ago

If I had a chef they’d hate me.

“Chicken nuggets again sir?”

“Yes! And god help you if the dinosaurs aren’t recognizable again. What the hell are they teaching you up in France? Clearly not teaching about the Jurassic period! I will have your ass deported next time. Get it right!”

[–] WoodScientist@lemmy.world 3 points 1 month ago (1 children)

If I were a billionaire, I would have the hyperbaric chamber, but have it powered in the most ostentatious way imaginable. Instead of having a motorized pump to pressurize it, I'm just going to hire a whole bunch of people with bicycle pumps to pressurize the thing for me. I'll hire like a hundred people, pay them absurdly well for the task, and have a hundred people show up just to perform a simple task that could have been performed by a cheap motor.

Also, my primary mode of transportation will be sedan chair.

[–] stelelor@lemmy.ca 3 points 1 month ago

See, this is how trickle-down economics are supposed to work!

[–] Gerudo@lemmy.zip 2 points 1 month ago

That was my first thought. For fucks sake pay someone to clean up!

Earlier I saw a stand-up comedian lambast a pregnancy test company for marketing their products as "the most sophisticated technology you will ever urinate on" as a tagline that plays poorly with women but strongly with men. Men would love to piss on something high tech.

[–] Kolanaki@pawb.social 3 points 1 month ago (1 children)

Just don't piss on electric fences, fellas.

Beachfront billionaire with a SCUBA hobby perhaps? That's a hyperbaric chamber.

[–] shalafi@lemmy.world 14 points 1 month ago (3 children)

What I thought too, but it's not like you can climb out the water with the bends and stroll home.

[–] loldog191@lemmy.ca 4 points 1 month ago

maybe we're wrongly assuming they use it inside their garage? maybe it's just being stored but idk

[–] pineapplelover@lemmy.dbzer0.com 2 points 1 month ago* (last edited 1 month ago) (1 children)

Yeah my idea exactly. What would you even do with a hyperbaric chamber

Edit: apparently it has health benefits

[–] shalafi@lemmy.world 2 points 1 month ago (1 children)

If I was filthy rich and had the space, I'd go for it. Be interesting to see how fast my flesh wounds heal, throw my wife in there when she has a headache.

It's a reptillian machine to reconstruct the human skin.

[–] JackbyDev@programming.dev 14 points 1 month ago
[–] Feathercrown@lemmy.world 14 points 1 month ago

It's their time machine, don't let them know you know.

[–] OldGrayDog@lemmynsfw.com 9 points 1 month ago

Time machine. That's how billionaires get richer, they go back in time and change little things to benefit themselves.

[–] LyD@lemmy.ca 9 points 1 month ago* (last edited 1 month ago) (1 children)

I could see an ultra rich scuba diver buying a hyperbaric chamber for their yacht. Decompression sickness is deadly and this is the only treatment. Hyperbaric chambers aren't common, there might not be one in an entire country. We get warnings about their availability when traveling. If you're diving off your yacht in a remote location, this could save your life.

That said, there's a step set up. Maybe they're shore diving at home and decided to splurge on something crazy and unnecessary.

[–] WoodScientist@lemmy.world 10 points 1 month ago (1 children)
[–] LyD@lemmy.ca 2 points 1 month ago (1 children)

Probably more likely, I didn't know it was useful for stuff like plastic surgery.

[–] WoodScientist@lemmy.world 8 points 1 month ago

Some people also just use them for purposes that are less clinical. Hyperbaric chambers back in the day were one of those cure-alls that were and are purported to treat all sorts of ailments, increase mental performance, sense of wellbeing, etc. I imagine it's a mix of real uses and bogus uses, but billionaires love to splurge on that kind of thing.

[–] RattlerSix@lemmy.world 8 points 1 month ago* (last edited 1 month ago) (1 children)

I think it's a Macy-Pan Hyperbaric Oxygen Chamber. I found an image but the link doesn't load

https://www.macy-pan.us/

[–] RattlerSix@lemmy.world 6 points 1 month ago (1 children)

That site sometimes loads and sometimes doesn't, but this appears to be the exact model

All that money and their garage looks as dirty and pleb as the rest of us.

Your second picture is a very recognisable location. I sussed out the house on Google maps - it’s a foreboding kind of architecture when it’s all closed up. I guess if you’re never there you don’t want people feeling like it’s accessible. The houses next door look like they have turntables for their cars in their driveways - that is some expensive luxury convenience there.

[–] jrwperformance@lemmy.world 3 points 1 month ago (2 children)

That looks like a BMW R Nine T. That's a cool motorcycle!

I was assuming it was a fancy cold plunge pool since there are 2 massive water chillers hooked up to it. But the 2nd photo makes it clear it's hyperbaric O2. The water chillers must be for climate control since you don't want any fans or anything else that may cause a spark in a high oxygen environment

[–] altphoto@lemmy.today 3 points 1 month ago (1 children)

Just close their garage door and unplug the control panel.
