Did the contacts really make a difference here or is swimming in affected waters the main hazard?

Who does just one? That's worse than not doing either. Since they're captive screws, doing just one can force the connector to wedge in crooked. I've had issues with tightening one too far before starting the threads on the other. Sometimes you have to go back and forth a couple times

There goes Vincent Adultman all strung out on ketamine again.

I definitely agree with you, however, I think needing to become self sustaining on earth is a goal that would be well served by trying to design a self sufficient system for mars.

Earth is big enough that it's really easy to forget we're all in the same fish bowl. Entire cities can flush their shit down the river and as far as they are concerned, nothing bad ever happens to them. The scale of earth makes us blind to the problems our actions and methods cause. The ecosystems also do quite a bit to protect us from our own actions

You can't ignore externalities in a space colony. Everything must be accounted for. That is what makes it so difficult to design for. Any small amount of waste will still accumulate over time and eventually becomes a problem.

The tighter scope and strict requirements of a space colony would make it easier to actually objectively measure how sustainable it is. You would know exactly how much external inputs you are delivering each year. We can then take the lessons and technologies that are absolutely required in a space settlement and use them to inform how to better be sustainable on earth. For example, solar cells used to only really be used on satellites, not because they were great on satellites, but because they were pretty much the only option that could stay operational for years. Now PV power generation is helping countries all over the world become a little more sustainable. The harsh requirements of space make us better at problem solving.

I totally agree that earth is our only option for species survival though. Anyone selling Mars as a "backup" for humanity is either delusional or a con man. I think developing the capability to keep a settlement on Mars is a worthwhile endeavor, but there is no way for humanity to thrive there. Any large scale catastrophe on earth will still be more survivable in select pockets on earth than anywhere on Mars.

There's no risk for a factory condition unit. This rumor started after people with units that had been dissasembled and reassembled had issues with vertical orientation. It turned out that it's very easy to mess up the seals that keep the liquid metal thermal interface in place. So units that had been previously taken apart had liquid metal slowly leak, causing overheating and/or shorting.

If you haven't taken the cooler off the mainboard, using the vertical stand is just fine. I haven't seen any evidence of factory assembled units suffering leaking. It does imply that user servicing of ps5's is a bit risky, and you might need to be wary of used units where you don't necessarily know the service history.

To avoid unnecessary confusion, taking the covers off to add an m.2 ssd does not add any risk.

I can't claim to have much experience in the matter, but I don't think people who just chill generally have chariots fitted with iron. Like if your neighbor happened to have a tank and a bunker, would you say they're just chilling?

The cabin is usually pressurized to the equivalent of 8000 ft asl. So the dispenser does have to deal with pressure changes. A simple vent hole aught to take care of that though.

I can't launch minecraft without first opening the microsoft app store signing out, then signing back in.

Well a hearty well done to everyone involved. And thank you for showing it to us. It is refreshing to see examples of people building up their community when the majority of news focuses on negative events.

Do you want some discouragement?

Stainless steel is stains less not rusts never. You would need additional measures to keep the stand from degrading over thousands of years. Your local archeology department could give you some pointers on how to accomplish that.

Or maybe you design the stand in such a way that the tungsten object is held firmly, but still easily visible in rusty stainless jaws.

How many people did it take to get this done? It looks fantastic for something that is just getting started.
