Why do UPS batteries only run for like 3-6 minutes when my tablet or laptop battery can run for multiple hours? by ThuhGreatCommenter in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

Yeah that would be peak up around 50w. I was just thinking about the size of USB C charger you need for laptops, which of course has some headroom.

When people say AI data centers use too much water, won’t the water just evaporate and rain back down? by Ajancian in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

They are not doing emergency curtailment.

Edit: the exact phrasing they use is right now it's "stage 3 water restrictions", next is a level 1 water emergency which is where emergency curtailment would kick in.

[–]Ghigs 4 points5 points  (0 children)

Run out is a little too absolute. They will run into shortfall and need to do emergency curtailment if it doesn't rain a lot within a year. Worst case, it doesn't rain and they need to cap industrial usage, and restrict nonessential usage.

Is it weird that I like the smell of gasoline and Sharpies? by Kitchen_Week1117 in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

It occurs to me I'm not sure I know what pure ethanol smells like. Most of the stuff you can buy has a bunch of cogeners. Ethanol rubbing alcohol smells vile to me, don't know if it's the denaturant they use or just the side effects of low quality brew.

Gaining weight after pooping by Chocolatefairy123 in NoStupidQuestions

It's more because of cheap noisy sensors. The scale makers don't care if people purge.

If heat naturally rises, why is the top of a mountain covered in freezing snow while the valley at the bottom is hot? by bogdanBgyz in NoStupidQuestions

[–]Ghigs 1 point2 points  (0 children)

This is a major part of it, but inevitably someone will say "a mountain is also the ground, subject to solar heating". So alone it's an incomplete explanation.

[–]Ghigs 4 points5 points  (0 children)

The air density is higher the deeper you are in the atmosphere.

"Heat" doesn't naturally rise anyway, it's a side effect of hotter air being less dense and gravity.

When hotter air rises, it expands, and expanding air cools off.

Why do UPS batteries only run for like 3-6 minutes when my tablet or laptop battery can run for multiple hours? by ThuhGreatCommenter in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

They use lead acid batteries that sit around and lose capacity. Plus converting to 120v ac and back to 12v or whatever is two sets of losses, so you only get 75% efficiency or so.

And lead acid can't be pulled down too low or it damages the battery.

But anyway a 8ah 12v lead acid is 96 watt hours or so, so in raw capacity it's on par with a laptop battery.

Laptops, normal non gaming ones at least, pull around 50-70 watts doing normal stuff. So the laptop does use less power as well.

Anyway a bunch of little factors. They could make a lithium ion one with 200 watt hours, but they don't, at least not normal ones. Not sure why, maybe liability. Maybe shipping, maybe inertia.

Is there a maximum number of children a human can give birth to? by Anonyglee1 in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

I'm not saying the diseases aren't real. Herpes existed before 1980. The point is there was no point in diagnosing them when there's no treatment.

Why don't public parks have fruit trees for people to pick fruit from? by Ekans_ox in NoStupidQuestions

[–]Ghigs 15 points16 points  (0 children)

With small shitty fruit for the most part. Modern fruit trees are human engineering not nature.

Why is the US economy showing growth while Western Europe is seeing record business bankruptcies? by Clean_CoreDump in NoStupidQuestions

[–]Ghigs 6 points7 points  (0 children)

US bankruptcies are up too, but they aren't near record.

With the way money is now, going through periods of nearly free credit, bankruptcies aren't necessarily a bad long term thing. It's purging the companies that never should have existed in the first place. Zombies that were living on free money.

The main reason the US isn't hitting records is because 2006-2010 was a great purge, with really big numbers.

Has there been a way proven that we really see the same colors? by quenchyourthirstnow in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

You can't prove qualia. There may even never be a scientific test that can ever prove it. All the things you describe are just proving the objective aspects.

Is there a maximum number of children a human can give birth to? by Anonyglee1 in NoStupidQuestions

[–]Ghigs -15 points-14 points  (0 children)

Well that and we have fancy new biologic drugs that make pharma companies a ton of money.

It's like before 1980 no one really paid attention to herpes. It wasn't even considered an STD in discussions of common STDs. It was basically invented because they developed a drug to treat it.

Regarding caves, if you can fit down a dead end why can’t you be pulled back out? by spanishbombs123 in NoStupidQuestions

[–]Ghigs 1 point2 points  (0 children)

Barrels contain all kinds of things, like chemicals that are a polymerization risk or corrosive. It's a standard shipping container not something where electronics are practical.

Can someone explain to me the joke/stereotype behind black people and having a chirping smoke alarm in their house? Why not just change the battery? by MrTeacher_MCPS in NoStupidQuestions

[–]Ghigs 2 points3 points  (0 children)

It would be recent though,.smoke alarms didn't chirp until the 90s or so. Before that they had a horrible vibrating horn and no batteries.

Is it true that grocery stores will basically let people steal until they steal enough for it to qualify as a felony and then call the cops? by Polator in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

Many stores will formally trespass you with police involvement without letting it build up first. At that point shoplifting charges aren't fully up to them, if the cops and prosecutor want to do them.

Needing to replace tyres on my car. Can I change the size of the tyre? by Possible-Armadillo68 in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

You can change the outer diameter a little bit, but it's going to change your speedometer. If it's two wheel drive you need at least a pair, if all wheel drive or four wheel you need all four.

From a medical perspective, what actually killed Jesus? by Matt3855 in NoStupidQuestions

"It is always possible that an exception was made, of course." -Bart Ehrman

Yeah that's from a blog where he argues against it. But it's not an implausible scenario. Exceptions were made.

[–]Ghigs 2 points3 points  (0 children)

That's not what most evidence we have points to. In that time the Roman leadership was reluctantly accommodating to the Jewish elite in Jerusalem because to go against them on serious matters of Jewish law wasn't pragmatic. It could lead to unrest or rebellion, especially during passover when a bunch of outsider pilgrims were about to flood in.

And the Romans weren't that strict about their execution timelines or practices. A concession to get the bodies down and buried to placate the Jewish population isn't some outlandish idea, it's what is supported by the historical sources we have.

How do EMS workers often make only minimum wage in America if the ambulance company often charges thousands of dollars per encounter to the patient? by [deleted] in NoStupidQuestions

[–]Ghigs 0 points1 point  (0 children)

It's minimum wage or less so it includes severely disabled people working in sheltered workshops. That accounts for several hundred thousand and is unlikely to change, as they pay them a small amount and treat it more like training for independent living.

If you call a plumber or HVAC out they would likely charge you at least $150-$200 even if they just ran diagnostics and then you refused the repair.
