I don’t mean BETTER. That’s a different conversation. I mean cooler.
An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.
If a CRT goes bad it can actually make people sick.
That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.
In the near to mid future, I think an answer to this question are Internal Combustion Engines. I love electric vehicles and look forward to the tech improving. But the sheer coolness factor of moving a large machine through perfectly timed and calibrated explosions is tough to beat.
As a subset of this, the fact that carburators worked as well as they did, until we had the technology to invent the simpler fuel injector, I think is pretty cool.
Constant velocity carburetors blew my mind when I learned how they worked, and I got the funniest introduction to them.
I had an Aprilia RS-50 motorcycle which had a slide-type carburetor. Instead of a coin-in-a-pipe throttle, this thing basically had a portcullis across the intake. Pulling on the throttle cable pulled the slide upwards making the aperture/venturi larger, allowing in more air, while also lifting a needle up out of the jet to allow more fuel in. It’s a 2-stroke race bike, so you could easily bog down the engine if you opened the throttle too fast.
Then I bought a Ninja 250F, which has constant velocity carbs. Which also have a slide, AND a butterfly valve. The butterfly valve is operated by the throttle cable to control power. The slide is vacuum powered from the engine, and opens and closes the venturi to keep the air velocity through the carburetor constant, in order to keep the suction at the jet constant. It also has a needle in the main jet which it lifts along with the slide, so the needle’s taper meters the fuel mixture for the amount of air going through the carb. This inherently compensates for air density; if the air is less dense the vacuum mechanism can’t pull the slide open as far so the slide doesn’t open as far, and neither does the needle valve. So it automatically maintains the mixture.
Which is why using constant velocity carburetors on the Rotax 912 engine is such a brilliant idea. A carbureted airplane engine with no cockpit mixture control.
RS50 is such a fun bike, and I know the pain with the carb, I have to ride mine uphill, also, just replaced the 12mm flat slide carb with a 17.5mm round slide, runs quite nice
I had one of the very few of them in North America. I don’t think they ever imported them at any great scale. I bought mine used, and it was obviously used as a track bike. It had a cylinder kit that took it up to about 72cc, the damn thing could do 70.
Please tell me this doesn’t run on gas! Gas explodes, you know?
I recognize that reference, but I can’t quite place it. Futurama? Star Trek: Lower Decks?
It’s from the “I, Robot” movie, but would fit perfectly well in Futurama hahaha
Heinlein’s “The Rolling Stones” had a similar description.
maybe I, Robot? been a minute…
It’s why I’m hoping that hydrogen ICE become a thing instead of going to full electric.
It won’t. Hydrogen has terrible efficiency even when fuel cells are in the pipeline. Putting it in an ICE only makes it worse. It’ll have some racing applications, but that’s it.
You have any sources for this? A quick glance at wikipedia says that hydrogen ICE has about the same energy efficiency as gasoline, if the engine is properly tuned.
Yes, that’s correct. Fuel cell efficiency is over 60%. The best gasoline ICE is around 50%, and hydrogen isn’t going to be much better.
The problem becomes especially apparent when you stack the end to end efficiency together. Grid -> battery for battery EVs, and grid -> electrolysis -> fuel cell for hydrogen. There’s a couple of different ways to run these numbers (are you using 120VAC or 240VAC or DC, for example), but when using like-for-like comparisons as much as you can, batteries tend to win at efficiency by a lot. Running hydrogen through an ICE is only going to make its biggest flaw even worse.
Edit: there is a recent breakthrough in fuel cell efficiency that might put it on par with batteries. Note that even if it works in production cars, a fuel cell would be turning an electric motor, not an ICE. https://www.youtube.com/watch?v=ISuUlc8widc
I fucking hate cars, including electric ones… And I still agree. Combustion engines are cool as hell.
Thoughts on motorcycles? Totally fine if you really don’t like them either, I’m just curious :)
Grudging respect.
I don’t like motorcycles either, but they are the “noble steed” of my country’s entire service industry, and being a worker in said service industry is a very sucky (and dangerous!) position to be in.
So I don’t like bikes. But. I respect their riders. Their lives are hard and they are therefore stronger than I.
Interesting, that’s very different in my country so I appreciate hearing your perspective!
Hope you have a good one :)
And the fact is “mechanic automated” system for me is what makes it even cooler. All you had to do to start is twist it a couple revolutions and bang, it works as long as you have fuel because everything simply works. Of course, today you have electronic fuel injection and so one, but if you want you can make it works just with a lot of metal to do the right parts.
Man, I’ll miss combustion engines (but I hope its use ends ASAP because planet can’t wait anymore)
That’s why I kinda like my carburated 2-stroke motorcycle.
Needs just 3 wires from the engine to work and 1 to shut it off. Weighs just around 100kg and will propel me to 90km/h with just a 50cc cylinder.
Not to mention the smoke, sound, and the narrow powerband, just love that feeling.
Whenever I hear a running hit and miss engine it brings a smile to my face, similar with small stationary steam engines. There’s a club in Baraboo WI that does a big meetup once a year where there’s just tons of early tractors and stationary engines powered by all sorts of different types of combustion with all sorts of creative new engine designs that stopped being viable around the time of the first world war. I haven’t been able to go most years but it’s really incredible to see so many wonky engines wirring and popping and hissing and clanking around, all while struggling to reach the performance of a present day lawnmower (and not a good one at that)
Suck, squeeze, bang, blow
Sounds like a good way to spend a Friday evening.
I never knew the complexity of ICE until watching the Garbage Time YouTube channel. They repair old cars (and sometimes break them to fix them later) and show the whole process, but do it as a hobby, so it’s all for entertainment.
Drag disagrees. If you want transportation with fire, ride a dragon. No need to pollute the earth. The emissions make it uncool, just like the ridiculous Mad Max cars.
Does your dragon not fart?

Username checks out. I see you everywhere, and your comments often make me happy.
I definitely agree with you that cars are terrible, and I wish they didn’t exist. Even though I’m a hater, I gotta admit the engineering and history behind them fascinates me, still.
Thank you!
I remember getting a hand-me-down digital ‘black book’ to store phone numbers during the age of the palm pilot. It had a ‘dial’ button and a speaker on the back. You could pick up the phone, put the speaker against the phone’s mouthpiece and it would ‘dial’ by playing the correct tones. Blew. My. Mind.
The Internet.
Early to mid 90s was peak internet, even go as far as late 90s still being pretty solid!
Early 2000 was best IMO.
Fair, looking back, was a lot of good on the net still, you thinking around MySpace launch was the last of the good times??
Up to around the launch of the iPhone I guess, the web was so diverse and so many ‘places’, before youtube, google, facebook.
Computers making Fennec Fox noises at each other over the telephone line. And that connected you to the world.
CDs and DVDs, because ownership beats convenience when you can get them second hand for pennies on the pound
I miss the satisfying act of slapping a cassette into a tape deck, then snapping it shut.
Also:
FUCKING LASERS DUDE! Lasers will never NOT be cool.
Why are the kind of holograms made by lasers not cool anymore? They’re just on credit cards and currency now. I always thought those were awesome. There used to be a hologram museum in Chicago when I was a kid. We went up there a few times and I always insisted on going.
The best ones were holograms of microscopes or telescopes and you could actually look through the eyepiece and see something through it!
And the technology has evolved that I can actually record and re-record to these plastic discs using lasers and it all fits inside a 1cm-tall drive that sits on my desk. And if the manufacturer uses high-quality materials, the disc will last hundreds of years.
Also some discs I can then either ink-print or laser-print on the top of it? Simply amazing.
Disney lost their old camera tech used to make a “yellow screen” with sodium vapor lights.
It’s actually better than a green screen because the yellow light is so specific that even if you remove that particular frequency of light, everything else still looks fine. You can do all sorts of things that would normally be very difficult to pull off with any of our green screen tech (like drinking water in a clear bottle or wearing a rainbow dress).
This was a really cool video!
Considering LEDs are so good at producing a very tight wavelength, I wonder if this could be replicated with more energy efficient lamps.
Or if non visible spectrum lights can be used to make similar alpha channel masks that don’t affect lighting the scene.
A laser, maybe, but definitely not LEDs. Vapor/gas lamps produce the narrowest frequency bands possible, because it comes from very well defined atomic transitions (Hz range). LEDs produce frequency bands with widths in the GHz/THz range, while semiconductor lasers can maybe reach KHz if they are really good. So, unfortunately, for this type of applications, vapor lamps would probably still be needed.
Source: I work with lasers and spectroscopy.
Edit: very good idea about using non-visible light!
Is there some filter that you could put up over the LEDs that would block everything but a very narrow frequency of light?
Well, one possibility is using something known as Fabry-Perot filter. It allows an extremely narrow frequency to pass, due to multiple reflections and interferences inside the material. Put the light source material within this filter, and you get a laser. That’s essentially the main difference between a led and a semiconductor laser. The filter makes only a narrow band of the emission be “stuck” there, creating a feedback effect that eventually tends to infinity, and a good chunk of that power passes through the filter reflectors, which are intentionally not perfect.
Other than that, I don’t think there is a filter that could be as narrow as the line emission from vapor lamps. Maybe using metamaterials, but a laser would be so much cheaper and easier. A vapor laser would certainly get the job done, but they are large and hard to maintain.
Also, waving a magnet around a crt was fun.
Yes!
Also, the static on the screen. I don’t mean snow, but the actual static that raised your arm hairs. Whenever my parents needed to leave a note for us, they’d just stick the paper to the TV screen and it would stay there because of the static.
Great way to not have a crt anymore.
Nah, that didn’t harm it.
Not in my experience. You use a degaussing tool (which is an electromagnet) on crts when the picture gets all “wonky” (technical term).
The internet
I love that about CRTs, man.
How the fuck could we invent a tiny pocket sized particle accelerator electron beam gun that magnetically aimed its fire with such precision as to hit every individual phosphor, with the appropriate charge to make the right color, across an entire fucking screen, and do that 30+ times a second (for TV, or 60+ for a monitor)…
Yet the LCD is the high tech fancy monitor when its just a little grid of globs being electronically fired? How did the CRT get invented before the LCD?!
Cars used to be cool. Every car company had some kind of sporty car, a couple cheap cars, a big luxury sedan and, a while ago, a station wagon.
Now every car is an SUV or CUV. Sedans are getting phased out. Cool sports cars don’t make money so they don’t make them. People don’t buy station wagons so they don’t make them. And they’re pushing big, angry trucks on everyone.
Slide open phones with a QWERTY keyboard. Those were the bomb.
I wish someone would being those back
Most weapons. Bows and swords are cooler than guns and knives. Trebuchets and catapults are cooler than any form of modern artillery.
Modern warfare, when it becomes necessary, should be fought purely with weapons designed prior to the 16th century. Just replace horses with dirtbikes and ATVs.
Guns are pretty neat once you start to understand the engineering and extremely precise tolerances that go into them.
Modern warfare, when it becomes necessary, should be fought purely with weapons designed prior to the 16th century. Just replace horses with dirtbikes and ATVs.
You do not want this, the level of suffering that came with these battles was insanely worse than the fighting we have today with guns/explosives.
I disagree, firearms are way cooler than bows or swords. Sure, swords are cool but there’s only so many ways you can make a pointy sharp metal stick, or put a string on a piece of wood. But firearms in the early 1900s where absolutely wild when it comes to internal mechanics. Same thing goes for siege weapons and artillery, a trebuchet, catapult or ballista are cool at a medieval exhibit, but they ain’t a Schwerer Gustav railway canon.
But this is a statement on its own. Now every gas operated gun is either a AR-15 or AK. Every “new” gun is a “Tactitech Eaglefire XK-34-1050-Superbadger Ultradog”, and at the end its just another AR-15 with some sharp bits added to it.
Older firearms where way cooler an they don’t make them like that anymore.
Surprisingly, 3D printing is where most of the firearm innovation is happening now. Some use off the shelf parts from common guns like the AR-15, others are completely printed. It’s a weird rabbit hole to fall into, but definitely interesting.
The “should this be legal/illegal” debate is its own rabbit hole as well.
It always struck me as weird that serial numbers and therefore the weapons tie to the owner are printed on the receiver. A receiver can be milled with a simple CNC mill or as recent development shown using 3D printers. We should rather serialize and register barrels, the one thing that needs highly specialized equipment to manufacture and what defines the guns caliber, potential muzzle velocity and has unique thread profile.
While yeah, AR and AK patterns are everywhere, there’re still neat things to find. The Kriss Vector has their innovative approach to recoil control, the Boberg pistol reverses the usual way rounds are stripped drom the mag.
The magic is still out there, but it never was nor will it ever be common.
Yeah, the most intricate gun in my eyes is the AN-94, canted magazine, recoiling barrel, specialized muzzle device, pulley system, 2 shot hyperburst. What were they smoking when developing this thing?
When you break it down, yeeting a small piece of metal, accurately, up to a mile, through the use of handheld controlled explosions, is way cooler than just yeeting a pointy stick with another stick and a string. So, I am inclined to agree with you.
From an engineering standpoint, firearms are so much more fascinating.
Still amazes me that at the end of the day, most of them are fired by what is essentially a mouse trap. I’m curious when electronically activated cartridges become acceptable. Imagine how much space/bulk you can relocate from a pistol without the need for a mechanical hammer/striker. Think about getting a crisp and responsive trigger on a bullpup style setup. How much more accurate could you be with a long range rifle if you eliminate the trigger pull from moving the weapon (have it disconnected from the firearm, like a remote camera trigger).
Dune style personal shields can’t be invented soon enough.
Then knife fighting will make a big comeback.
LED panel, which really is just a bajillion very tiny lightbulbs.
It is not, but for the sake of the argument it’s ok.
I dunno about you, but I have a hankering for the mid-to-late-80s aesthetic, but specifically that taken into sci-fi. I’m talking Cowboy Bebop, Outlaw Star etc. 80s tech but… Future!
Everything’s so chunky and functional. It looks like you could hit it with a sledgehammer and it would still work!
Basically, BUTTONS! Gimme buttons, lots of big buttons! I want things that go click so I can be sure I’ve pressed them. I don’t want a tiddly little touchpanel for my washing machine, I want a button that goes CLACK when I press it!
Any mechanical regulation process that used to be handled by actual machine parts. Think of the centrifugal governor, this beautiful and elegant mechanical device just for regulating the speed of a steam engine. Sure, a computer chip could do it a lot better today, and we’re not even building steam engines quite like those anymore. But still, mechanically controlled things are just genuinely a lot cooler.
Or hell, even for computing, take a look at the elaborate mechanical computers that were used to calculate firing solutions on old battleships. Again, silicon computers perform objectively better in nearly every way, but there’s something objectively cool about solving an set of equations on an elaborate arrangement of clockwork.
The idea of punch card programming blows my mind.
He’s not talking about punch card programming, that’s way more advanced and requires a Turing machine, what he’s talking about is computers as the term was using before what you would think as a computer existed.
The example in the video is for the computer on a cannon in a battleship. If there wasn’t a computer you would need to adjust the angle and height of the cannon, but that’s not something a human can know, what humans can know is angle to the ship and the distance to it, so instead you put two inputs where a human inputs that and you translate that into angle/height. Now those two would be very straightforward, essentially you just rename the height crank to distance. But this computer is a lot more complex, because wind, speed, etc can affect the shoot, so you have cranks for all of that, and internally they combine into a final output of angle/height to the cannon.
That’s cool, but punch card programming blows my mind.
Centrifugal governors are possibly one of the origins of the phrase “balls out” or “balls to the wall” (although many say “balls to the wall” has to do with the ball-shaped handles on old aircraft throttle levers)
Also somewhat similar to governors are centrifugal switches, which are used in just about anything with an electric motor to disconnect the motor from a capacitor which gives the motor a little extra juice to get it going (I like this video for an explanation of how they work)
I didn’t know that was a thing. Thanks! I’m honestly surprised some MBA bean counter hasn’t replaced those with a chip of some sort by now. Really cool!
To add, there is something about those old 40s and 50s era technical films like you linked that is just so… I don’t what exactly it is, but I find them fascinating and genuinely informative, even though they are explaining tech that is decades obsolete.
It’s pretty awesome that they are still available 70+ years later in excellent quality!
H model C-130s, the ones with the 4 square blade props? The engines and props are mechanically governed. There are electronic corrections applied, but the core of the systems are purely mechanical. Still flying.
Source: former flight engineer on them.
Someone showed me a record turntable with what must have been a centrifugal governor! What an ingenious device. (I got the impression from him this was unusual for a turntable, at least…)
I was under the impression that all wind-up turntables (I.e.: from the shellac records and steel needles and mechanical reproducers era) were using mechanical governors
Maybe I’m wrong though.
Oh I know little to nothing about turntables, so you’re probably right :-)
Video games. Way back then there was imagination involved, and companies took risks. Nowadays every game seems to iterate on the same tired formula. The only recent entry I can think of that bucked this trend in the past few decades was maybe Portal, but there have been few to no other recent games that come to mind. Fight me.
deleted by creator
What is the formula you’re talking about? Games are so diverse it’s pretty hard to see what single formula there could be that covers them all.
Not a fan of indie games are you?
Baba is you, is a pretty original puzzle game. I’m not really into factorio, but it made tower defense cool again. There’s lots more that are weird and interesting like brigadore, airships conquer the skies, cruelty squad, superliminal.
As far as I remember, portal was a mod or indie game that valve picked up because they thought the idea was really good. It was really good.
A student project, actually. Valve saw a college student doing fun/weird shit inside their engine and went “You’re hired”.
That only makes it cooler
Literally play any indie game.
The imagination came from the limitations of the hardware.
Computers today are too powerful for gaming. Its resulted all the famous studios racing to the bottom with graphics their primary and generally only concern, and everything else coming a distant second.
But at least it left the door open for indie devs, whose lack of resources and experience are still capable of keeping that ember of imagination and innovation burning.
Alan Wake 2 and Control are fantastic!
Along with the others I’d also mention Outer Wilds and Viewfinder
You’re talking about the AAA space. Fuck those games. Play indies. There are so many creators carrying out the legacy of game development you’re talking about. Don’t buy the games directed by suits. Currently I’m playing Factorio: Space Age, which is great. I recently played Lorelie and the Laser Eyes, which is a really cool puzzle game where you’re actually going to want to write notes on paper, which feels very classic. There are so many out there, but you actually have to look because the don’t have the marketing budget of Ubisoft or EA.
