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.

It's why I'm hoping that hydrogen ICE become a thing instead of going to full electric.

[–] VinesNFluff@pawb.social 17 points 11 hours ago (1 children)

I fucking hate cars, including electric ones... And I still agree. Combustion engines are cool as hell.

[–] Cris_Color@lemmy.world 2 points 4 hours ago (1 children)

Thoughts on motorcycles? Totally fine if you really don't like them either, I'm just curious :)

[–] VinesNFluff@pawb.social 1 points 2 hours ago

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.

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.

Please tell me this doesn't run on gas! Gas explodes, you know?

[–] grue@lemmy.world 6 points 15 hours ago (2 children)

I recognize that reference, but I can't quite place it. Futurama? Star Trek: Lower Decks?

[–] Nibodhika@lemmy.world 10 points 14 hours ago (1 children)

It's from the "I, Robot" movie, but would fit perfectly well in Futurama hahaha

[–] solrize@lemmy.world 3 points 14 hours ago* (last edited 14 hours ago)

Heinlein's "The Rolling Stones" had a similar description.

[–] oozynozh@lemm.ee 2 points 14 hours ago

maybe I, Robot? been a minute...

[–] ReeSilva@bolha.forum 17 points 15 hours ago

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)

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.

[–] MattTheProgrammer@lemmy.world 1 points 3 hours ago

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.
