- Comment on What's the deal with AI datacenters using water for cooling? 20 hours ago:
If you remove the thermostat and redline it in a garage it still won’t be able to keep up because it doesn’t have the airflow that’s required
The concept of closed loop cooling for servers has always existed and it works for home computers. What is conventionally called closed loop cooling just means that you transfer heat from the computer to a liquid and then from the liquid to air. Transferring 100MW of heat to the air is what makes this difficulty especially in a stationary computer.

The problem is the rate that it leaves the local system is faster than the rate it returns so in the long term the local systems lose water. If you want to look at it even deeper it’s actually sooo much worse as it also causes local droughts which kill flora which then cause less water to be stored in the local system which then kills more flora and so on as you get desertification and then by pumping down aquifers those aquifers can collapse and never hold the same water that they used to hold
So yes it does fall back to the ground but that’s an explanation for a 10 year old learning about the water cycle. An adult should be aware of how much more damaging it is

Car cooling systems are stupidly expensive, run at temps that would damage computer CPUs, run outside, and have a really nice advantage over computers which is that at higher heat loads they also tend to go faster thus cooling them off faster.
Now imagine you redlined a dozen cars for days on end in a garage in the middle of the summer do you think you might damage some components?
It is still very possible to use closed loop cooling on data centers but any system you build needs to be able to work in summer temps which can be as high as 35-40C and needs to do that without letting the computers exceed 60C. An air cooled system to handle that much heat is going to be very expensive and use a ton of power (and power generation also uses water)

People mentioned corrosion which is true of all sea water systems but in evaporative systems you also have the addition of salt forming on all the evaporative surfaces which can drastically increase corrosion more than normal seawater and cause fouling
So to do this properly you would want an RO system making freshwater before the cooler which at that point it would make more sense to just have a separate company doing desalination.

- Comment on Turbine go brrrr 1 month ago:
Supercritical CO2 has been looked at a lot for the Brayton cycle which can get 50% efficiency compared to steam that generally caps out around 34%
The US and china both published studies talking about a brayton turbine but to my knowledge no commercial plants running off of it have been built yet
- Comment on Sitting in traffic 1 month ago:
My 3 mile bike ride takes 2 minutes longer door to door than driving.
As has been repeated a few hundred times in this thread already, the part that makes it takes so long is car centric infrastructure. If you live in suburbia where you have a population density of 1k/mi2 (400/km2) you will have to travel a much more significant distance than if you live in a place that has 9k/mi2 (3500/km2)
Then with less car centric infrastructure the benefit of having parking right next to work starts to go away and the extra space can be used to shorten commutes as well

You know they give nitrous to people intentionally during surgery and dental work?
Like you can wear an O2 monitor while you take a whip it and track your oxygen level and I have never seen it drop below 85% which is the level where they start to get concerned in a hospital
Taking opiates cause you to just stop breathing and I had to have a breathing device following a surgery because my O2 levels couldn’t be maintained… and people get prescribed opiates and take them at home all the time with no monitoring

Don’t asphyxiate yourself, don’t do it a bunch of days in a row, and eat some food with B12.
- Comment on Start-up idea 2 months ago:
There are also different standards when you care about the environment. Old school fridges used incredibly bad greenhouse gasses (R22 and R142B) and were significantly less efficient using approximately $250 MORE energy per year than a modern fridge (1750 kWh vs 450kwh) so only factoring in your electricity bill you could buy a $2500 fridge every 10 years and break even and if you got a cheaper fridge like a whirlpool you could get a new one every 5 years for 50 years
Don’t get me wrong there is still planned obsolescence but a lot of the older designs aren’t as perfect as people like to remember them being

How would they start considering how expensive it is and with the additive?
Like nitrous canisters are decently cheap
- Comment on Sea Level 4 months ago:
Your rent right now can be thought of as a large payment split into 12 equal pieces (even though months aren’t actually equal) and your rent payment is just 1/12 of that. If there were 13 months it would just be split into 1/13 so each months payments would be slightly smaller to be the same total
If we transitioned it would take years and for at least some amount of time of overlap they would show both prices so it would be much harder for them to just jack up the price like they would prefer to do

That is just such a strange law
I tried googling it because I was curious and the only thing I could find was about temporary structures
Is there a name for the law that I could search?

So woodland that can’t have a permanent dwelling is affordable but woodland that can is cheap?
Like that would make sense if the construction of the building was different but if it’s simply just how often you can spend time on your own land that’s ridiculous

A car weighs 2000-4000lbs and can be produced in a mostly automated factory
A reasonable sized house still weighs 50-100k lbs that’s a lot more material and you have the land it is built on. It then takes multiple people days to build.
Houses being as affordable as cars is a pipe dream

The time scale is the other big difference. A credit card is intended to be paid off at the end of the month and gives you much better fraud protection than a debit card
Products like klarna instead have you pay off a tv over months and offer you no real benefit besides racking up debt

Am I missing something here or what’s the problem? There are parking spots and there is an area where you can’t park that’s clearly marked.

Isn’t there a vast improvement by having a clean set of tabs that you can read the names of compared to 100 little tabs that you have to click through?
- Comment on Why do some people have so many tabs open on their browser? 5 months ago:
Why not just close them and open them back up later? Like you can bookmark the pages so you don’t lose your spot but I find it annoying to find the tab I am looking for at around 10 I would imagine it’s much worse at 200

Racism towards clankers? Maybe I’m not up to date on my lingo but aren’t clankers, robots, I.e. not a race? Or am I missing something?
- Comment on Had to look this up 5 months ago:
You can make fun of stereotypes without being racist.
This is literally just a commentary on how JK Rowling wrote her other characters like Cho Chang and Kingsley shacklebolt.
No reasonable person is offended by the joke because it’s making fun of the stereotype not of the actual race.
- Comment on When "AI" content becomes indistinguishable from human-made content, is there, philosophically speaking, any meaningful differences between the two? 5 months ago:
It’s a question of ethics because why would I pay money for what I consider stolen property?
Courts ruling one way doesn’t make something ethical.
Personally I would never knowingly pay someone money to ask an AI that was trained on stolen data to generate a picture that they then print off. More so I would judge anyone that did pay more than the cost of printing it on a paper. It’s not art to ask a computer to use stolen art to make a prompt
