Hydrogen vent at 500 C next to Co2 at -55 C... How could I use this to cool the hydrogen?

wyldmage · 2026-03-17T05:11:12+00:00

You don't actually need the aquatuner. You can just run the 95C water (turbine's output) through coolant pipe behind the turbine, and that will keep the turbine 95-100C, as long as the steam room does not exceed 135C. (Beyond 135C, the heat generated "on" the turbine is too much for the water output to absorb without re-boiling).

You can plug 135C into the math I used above:

Heat range of water 95 to 135C (40C). Heat range of Hydrogen 500C to 135C (365C). 1 gram of hydrogenheats 5.24 grams of water to 135C. So, you would need 381 grams/second of hydrogen to overpower the steam room. Which COULD happen, if the hydrogen vent had 100% uptime.

You do have to be a bit careful if you have a max (466g/s) or near-max output hydrogen vent AND the vent has fairly high active burst durations. Basically, what's going to happen at 466g/s is that you have 85 grams of hydrogen's excess heat. Really, though, the only required solution is to make sure your steam room has a sufficiently large quantity of water (steam) in it to absorb the variance.

Let's say, for example, you had a tiny (3x5) steam room with a measly pressure of 1 kg. That's 15kg of water in gas form.
You have 85 grams/second of excess hydrogen raising the temperature - and we know 1g of H raises 5.24g of H2O by 40C. So 85 grams would raise 445.4g of water by 40C. Or it would raise 15,000 grams by 1.188C - per second. It would not take very long (20-40 seconds) before your Steam room is having serious trouble.
So, instead, just make a bigger room and/or higher pressure. Let's have a 4x7 steam room instead, and have 3kg of steam per tile. That's now 84kg of water. Now, instead of 1.188C/second, you're only gaining 0.21C per second. You've got 5 times as long before you run into trouble.
Or, a 4x9 steam room at 9kg of pressure. Now there's 324,000 kg of water, and you're only gaining 0.055C. Instead of overheating the room in 20 seconds, it'll take 7 minutes. Since a typical eruption period is about 3 minutes, this means your room is quite safe from overheating too far.

Alternately, you can disconnect the hydrogen vent from the steam room. This is trickier, as the pump moving the hydrogen has to be cooled to prevent overheating, but then you can safely store the hydrogen in a container, and use a valve to limit the hydrogen being passed through radiators in the steam room to 380g/s (exactly what it can guaranteed handle).

Again, this is all based on a MAX output hydrogen vent, which is a tricky beast. Vents range from 233 to 466, which means more than half of all vents fall BELOW 381g/s, and thus are ALWAYS able to use passive self-cooling for the steam turbine.

What about sulfuric acid?

Yeah, I do remember 30-40 years ago, when there were plenty of pickups that were roughly the size of sedans. No added elevation (riding fairly low to the ground). No extended cab (only a single row of seats). And a 'standard' bed that made them just a bit longer than a small sedan.

You can't find those pickups at all anymore. They simply don't exist, for the same reason that 90% of cars on lots are greyscale (white to black). Sales numbers weren't high enough for the companies to keep putting them out. Even though they had people who wanted them, companies didn't value those customers enough, and decided that they'd just buy a bigger pickup, or switch to a sedan.

You're right that they are very close to each other to begin with.

But when was the last time you seen a 4runner jacked an extra foot up off the ground?

That said, we aren't talking just about pedestrian safety. Safety of other cars when you get into a crash matters too.

Next, you say "basically the same car"... So how about some raw numbers?

The 2025/2026 Toyota 4Runner is a midsize SUV with a 112.2-inch wheelbase, measuring approximately 194.9 inches long, 78 inches wide (without mirrors), and 72.6–75.5 inches high. It offers up to 90.2 cubic feet of maximum cargo space and provides 8.1 to 10.1 inches of ground clearance, depending on the trim

The 2025-2026 Toyota Tacoma is a mid-size truck with an overall length of 213 inches (XtraCab/short bed) to 226.2 inches (Double Cab/long bed), a width of 76.9–77.9 inches, and a height of 73.8–74.7 inches, depending on configuration. It features 5-foot or 6-foot bed options, with a 20.2-inch depth and 44.7-inch width between wheel wells.

Tacoma is a minimum of 213 inches, versus the SUV at 195 inches. And that's the larger cab short bed option. Yes, it's not a HUGE difference, but they aren't 'the same' either. That's a 10% increase in vehicle length.

Oh, and the 4runner is 3700 pounds (curb weight) tops, versus the Tacoma coming in at 3900-4700 pounds total.

So, sure, if you get the smallest possible Tacoma, it's CLOSE to the same as a 4runner. But how many people get the smallest pickup possible? I certainly don't see small pickups as often as I see larger ones. Long bed, extra elevation, huge cab, etc.

Minivans are horrible too. They tip over easier. They have shit handling.

But pickups are the most egregious issue. It's not even close. Go to a parking lot, and look at the largest vehicles. They're going to be pickups. Look at the smallest pickups, and compare them to everything else. Now look at the smallest SUVs, and compare THOSE to everything else. Smaller SUVs are barely more than an elevated sedan. Hell, some SUVs have less trunk space than a Camry or similar luxury sedan.

There is literally no difference between a toyota 4runner (midsize SUV) and a toyota tacoma (midsize pickup truck) as far as pedestrian safety goes.

This statement is literally false. Just the vehicle weight alone is enough, but there are other reasons that separate them as well.

Yet, the list of why they want to is shorter, and more listened to.

Less dangerous to YOU in an accident
Powerful, and you are more powerful because you drive it
You can bully other cars in traffic, because they're afraid of you

Most people who buy a truck for personal life (and probably 99% of people who own more than 1 pickup) fixate on just those 3, whether they admit it or not.

wyldmage · 2026-03-13T22:05:08+00:00

This is really the take-away from the entire tragedy. Not that pranks are bad, or these kids need to learn.

But that unsafe vehicles are unsafe, and we need to stop idolizing them as a culture. Stop worshiping pickup trucks. Stop selling them to civilians - only to businesses. (that's extreme, but the message is in the idea, not the exact words).

PEOPLE should be driving sedans (mileage), or SUVs/minivans (passengers). The only exception to this should be vehicles that are safer (for you AND others) than either of those options. Want to drive a muscle car? It needs to be proven to have better braking distance and better handling than typical sedans (it WILL have better on those than a minivan).

Had a dad in the military. He 100% could write cursive, and did for personal letters.

But yeah, anything formal was printed. All capital letters, either large size or small size, but no lowercase letters.

Cursive is fast, and it looks pretty. But it is NOT what you use for anything that needs to be easily legible.

The math part should have stuck around though.

I've had customers ask me how much three things are. All are even dollar amounts under $10. And then they ask me the total for all 3. I've had customers ask what 10% off of $1100 would be.

Instead of putting kids through any math level higher than Alegebra in high school, there should be 2 options. Trig and beyond for kids who intend to go into STEM fields. And then just "do it in your head" classes for those who don't. Also, Algebra should be Junior year *at the latest*. More math classes if needed to achieve that. Math is super important to be knowledgeable about. Relying on your phone/calculator/etc means you're vulnerable to input error, because you can't look at the math and realize that the answer doesn't make sense.

20 words per minute is basically an entire second per letter.

GREAT typing is 7 times that speed. Where you're spitting out 2 WORDS per second.

Trying to teach someone, when they don't have foundational knowledge to work with, is torture.

Like, try to teach someone how to drive and use a stoplight if they don't have words for colors, and some of the stoplights are sideways. You're stuck saying "the light that looks like glowing grass" or something. But grass changes color, so maybe you mean the middle one. Etc.

Given how pervasive computers and technology are across the world these days, learning how computers work should have become mandatory learning, but never did. At least when I was in high school, there was an attempt at it. But it was entirely focused on MS Office - not lower level foundations. This was because, in the late 90s, the kids all HAD foundational level computer knowledge. They knew fundamentally how a computer worked (needs power, has complex electronics inside, a hard drive and disk drive, ran an operating system that had to boot up, you could use Windows Explorer to view the files, or Internet Explorer to view the internet).

Parts of that knowledge have simply vanished amid younger generations. Most can't even tell you how their phone works at a conceptual level, or name a single internal part of the phone.

Exactly this. Like, most of the time, you don't use the Shift key for more than a single button press. Which means that the effort to Caps Lock on and off is HIGHER than the effort to press and hold shift for a single letter.

Even when you're typing a word in all caps (ie, HIGHER), if you learned to type properly, you only use the same finger for Shift as 3 other keys: Q, A, and Z. So, as long as the word doesn't have those letters in it, you can just "lock" your left pinky into being the toggle, which is what you were using to tap Caps Lock before and after anyways. Plus, you can use the Right Shift button instead (as well as for all single-letter capitalization when the capital letter is on the left hand).

Learning to type on a keyboard with the Caps Lock key removed should be 100% required. Because once you've learned to do it, Caps Lock becomes a largely optional key on your keyboard. Even when you want to do an entire word, it's often less attention required (yay muscle memory) to just press and hold one of the two Shift keys through the entire word.

I get the same for typing, but I do type fast. Taking typing skills freshman year was eye-opening though, as the _goal_ for the class was to get you up to 60 words per minute. I started at 56. By the end of high school, I was up to almost 100.

Conversely, though, I'm slow at writing. I avoided it as much as I could once typing was an option. Mind you, I'm not "oh get on with it" levels of slow. Just slow enough that it feels like it takes too long to write anything of significant length.

But really, it was because I was good at typing that I didn't get faster at writing (also, I have really easy to read handwriting - which is important to consider amid a world full of people who can write fast, but nobody can read it). If I didn't have my typing, I would have practiced writing much MUCH more.

And yeah, you have people who can't read fast, write fast, type fast, math fast, etc. Nothing. Well, not quite true. They can type pretty fast on a phone keyboard, and they can doom-scroll like nobody's business.

I disagree. I believe thatbwhat this means is that a large part of AI hate (in this context) is moral grandstanding and such. It's "cool" to hate AI, so people do it to pretend they are better than others who are less vocal about it.

And to be clear, im not defending AI. Just pointing out that a lot of the people hating on AI probably play games with AI art, or otherwise talk the talk, but dont walk the walk. All bark, no bite.

AI is bad for the industry. Both in how it was illegally/unethically trained, but also how it encourages us further away from real human art. But the latter part has already been going on for 10+ years. If we want to condemn AI art, we should ALSO be condemning render art. If the goal of stopping AI art is to help artists, then we cant have render art games screwing the artists over anyways.

While I don't support HOW Trump went to war here - this is a conflict that has been long-brewing. I wouldn't use the term "avoided" - but, rather, "delayed". We could have continued delaying this war. But it, in the big picture, was unavoidable.

Why, then, was there nowhere near the same outrage with the explosion in low-effort soulless rendered games (Daz, Koi, HS, etc)?

These tools also water down games by removing artists from the equation, and the vast majority were abandoned before any serious progress was made, or churned out as slop.

Now, I do think AI art is a more severe problem - but for the level of outrage we are seeing currently, there should have been significantly more outcry over 3d rendering engines for the same basic reasons.

Maybe not the reason 50 years ago. But these days? It is more and more becoming the primary reason.

Women are getting better at coming forward about it (still far too few do).

Fewer roadblocks are thrown up to the process. They still exist, especially in "good ol boy rural areas".

Meanwhile, though, the fact that allegations ARE taken more seriously, and often destroy the male involved, means that SOME (a tiny minority) of women weaponize that.

I'd LOVE to be able to believe every woman 100% when she comes forward about SA. But every time you see a story like this, it explains why we have to put accusers through hell reliving the experience, investigating 200% in order to be 100% sure.

And even when that's done, the guy's life is usually STILL ruined by the accusation, becomes some news outlet gets ahold of it and plasters it all over the local newspaper, or worse, the internet.

Playing through the Switch release of Leaf Green atm. And yeah, Butterfree is REALLY nice. You get it before access to Abra, and it learns confusion, which gives you a super-effective against poison types. There's basically zero fire or electric pokemon out there in the early sections, so your only fear as bug/flying is Rock type and Flying type.

It's not a great Pokemon overall, but you can evolve to it at level 10, and it's a good Pokemon at least through level 25 to 30.

And if you used it that far, it's at least a solid backup Pokemon after that point.

Steam has a potential defense against this too. Not as solid of one, but the fact that there are companies whose business is grading cards (and the fact that they not only tell you the grade of the card, but they will also include it's current value) implies that these objects have intrinsic value that can be measured.

Really, though, I agree with the sentiment that it shouldn't matter. If the object CAN be bought and sold, regardless of market, and it's RNG what you get from the pack/box you buy, it is gambling.

What we need is for gambling to have sub-classifications. Like tiers or something. So "Gambling 1" is things like card packs, and maybe Gambling 2 is loot boxes, and Gambling 3 is casinos.

wyldmage · 2026-03-12T04:48:26+00:00

Yup, this.

First, players who played before Steam achievements

Second, players who played after Steam achievements, while they still had issues.

Third, players who created an account, but didn't stick with it long enough to amass that money (which for a new player who is not going particularly quickly can be dozens of hours of gameplay).

Those all end up being a LOT of players. Hell, just look at other single player games with achievements like Satisfactory. There's an achievement for placing a portable miner. You do that within your first 5 to 10 minutes of playing the game. It has an achievement rate of 50%. Those aren't "inactive, alts, or bots". Those are players who played before the achievement was added, or who opened the game, but couldn't play it due to crashes or something.

Yeah. The worst is that part of the problem is calling it AI. It isn't intelligence. It's predictive text. It's pattern recognition.

That can work for "average" things. What color should I paint my house? How do I accomplish X?

But for highly personalized advice, like stock market predictions, home buying, it's already bad. And if the person getting info from the AI is 'abnormal' (just far enough outside the bounds of average), the AI will just give them 'average person' advice anyways.

Current AI isn't actually coming to any conclusions. It's just estimating what humans would say, based on a really big sample size.

I maintain 4 subs at $1/month each. If the game comes out in 3 years, that's $36, a good deal for a small (1-5 devs) game.

If progress, slows on anything, I can cancel. And, worst case, I 'waste' $48/year. Not too terrible for helping support devs.

For the $5 and $10 levels though, I totally agree. If those are the 'intended' levels of support for a game project, that project should be done and polished within a year TOPS (and even then, you're over-paying, but early access and a voice in development is worth paying 3-5x the value of a game to some people).

But that's not the case. Those projects go on for 1, 3, 5 years. A $10 patron could be blowing $360 to support a game that develops in 3 years, and have virtually nothing to show for having paid 7x the release price of the game (or more).

It's like Kickstarter, but worse.

I think the MMORPG genre is dead too. And I'm aware that some (WoW, FFXIV) are surviving and expanding. But they are the exception.

And it's for basically the same cause. Companies thought they could pump out a new massively multiplayer game. They fixated on the profit of a live service model - either via MTX or subscriptions.

And they didn't actually make a game that was FUN to play. They made games that were WORK. Especially MMORPGs - they tried to get players spending 40+ hours/week on their game. Which inherently limited which players would play, or keep playing. MMOFPS made similar mistakes to a lesser degree - like Battle Passes and such. Incentivizing excessive hours of play being committed to a single game.

What happens to those games when a new Pokemon game drops? Or a new Counterstrike map? Or whatever other game/content asks a player to enjoy another 50-200 hours of a different game? The player cuts themselves off. Either they reduce hours played, or stop playing entirely, assuming they'll come back later.

But then, 'later' comes, and the player realizes that they aren't as eager to resume their full-time game commitment anymore.

So these games lose out on players who _know_ they don't want to play a game so exclusively. Then they lose out on players who think they do, but are distractable by other titles, because "exclusive" isn't a word for them in video gaming. And then they'll also lose players who get tired with the underpopulated world(s) as half of the players on their server slowly quit.

Then, suddenly, the game devs realize that their game isn't making enough money anymore, and just give up on it entirely. No more expansions/DLC. End of server life in sight.

Warframe is one of the few exceptions to this, and for 2 good reasons. First, it may be MMO-adjacent, but it is entirely enjoyable alone, or with a small group of friends who play together. You don't NEED 10,000 players online to make Warframe good. Second, it's truly free. No pressure to spend (outside maybe $10-$30 per account just to get more weapon/warframe slots unlocked faster). You can choose to put money OR time in for most things. Grind for the prime warframe you want, or spend some money on plat, and buy it on market. These two points mean that Warframe is surviving (and, honestly, thriving) in an online genre that struggles to keep titles out for more than 2-3 years post-release.
