Sounds a little steep any discounts given?
Bring 3 friends and your son and for the same price you’ll get the full 96 hour experience
My son said that received the true Titanic experience.

I think people would pay ticket price to watch a rich person be dunked into an Ohio river. Think of the merchandising revenue alone!
The event would pay for itself! /s
If I got to pick the rich person I’d pay double!
I mean, today, entirely seriously, I spent about an hour looking at used prices for air receivers for this exact purpose. You can totally get 250 gallon tanks rated to 300 psi that are about the right size to fit one person and all the electrical components inside. Cut off one end and replace it with an acrylic/poly-carbonate dome, add a keel, ballast system, and thrusters on the outside, cover it all with a fairing, and you’re good to go!
I’m thinking I could prototype a functional sub rated to 150 m for around $10k. Totally worth it.
Trust me, I’m an engineer as well lol
So how does that work, is the 300psi rating calculated by the difference between internal and ambient pressure? Does it not matter whether the greater pressure is internal or external?
Oh no, it totally matters. In the case of a receiving tank, rated for 300 psi internal pressure vs 1 atm external. The limiting factor there would be tensile strength, or how well the material resists being pulled apart. Sticking it underwater with 1 atm internal would test a combination of compressive and tensile strength, but more compressive (if it were a perfect sphere, it would just be compressive). Good news is, steel is a relatively good choice for both.
Which was one of the complaints about the material choice for the Titan; Carbon fiber has high tensile strength, but low compressive strength. The strength of the hull had more to do with the resin than the carbon fiber itself. In fact, I’d be curious to know if there was even a benefit to using carbon fiber over regular fiberglass. That and it’s hard to inspect for fatigue compared to other materials like steel.
Case and point: Deepsea Challenger, the sub used by James Cameron to go to the bottom of the Marianas Trench, had a pressure hull made of steel.
I guess using propane tanks for submarines is fairly common

Oh neat! I started looking at propane tanks, then switched to air compressor receivers when I found ones rated for 300 psi, knowing propane is generally 100-200 psi. But now I’m finding some propane tanks rated for 600+ psi…sooooo…guess it depends?
can it at least use a licensed Xbox controller?
Unfortunately, their older brother has dibs on the good controller.
Sorry, best I can do is a 2005 madcat controller.
We’re proud to partner with GameCube for the controls!
Oooof
Let’s take it to the Challenger Deep. Definitely sounds like the kind of place that’s easy to get to. It should be fine.
The Hunley 2.0?
Ohio River Valley is not a bad destination in the ensuing climate collapse. See you there for the water wars!
I’d go just to play “drunk driver or crime ditch”
That propane tank is to the real submarine what Kbin is to Reddit. Almost sorta kinda like the real thing, but you can’t have the real thing anymore because it exploded, so you’d better get used to sloppy seconds.
Listen here, Kbin has been around for what, a couple weeks? Reddit is two DECADES old. We built it there and we can build it here.
