That's almost certainly intended behavior, otherwise any underscore would trigger formatting (much like the asterisk does instead of allowing snake_case_naming
The markdown specification recommends using asterisks specifically for that. It is not exactly intended, but left to the interpreter. Most markdown interpreters leave the underscores intact if they're inside a word.
Deceptive marketing and scams are interchangeable because they're the same thing—the direction doesn't matter. I put scam first because it was in the previous commment.

There's a bit in 'deadpool and wolverine' where they're in the multidimensional junkyard and characters from marvel properties with aborted film projects also end up there. So like 'blade', and the various attempted 'fantastic four' movies.
I actually quite liked all of them to some degree. I even enjoyed the awful CGI rubber ninjas fight scene; I know the movement was unrealistic but I was young enough that I figured it was superhuman vampire flexibility. However, I agree that the first one was the best.
Trinity was my second introduction to Ryan Reynolds, so that helped some. (I'm pretty sure I first saw him in Van Wilder.) Also Wesley Snipes saying "gootchie goo" to a baby was pretty hilarious, though reflecting on that I'm not sure they ever explained how he got that child back to its mother.
Also, I think Natasha Lyonne was in that. I knew I recognized her when my wife started watching OitNB, but it took me forever to figure out why.
The "rubber ninjas" instantly ruined the film for me. That scene is seared into my memory, and takes second place after the entirety of The Phantom Menace for film betrayal.
Like I mentioned, I honestly kind of enjoyed it as I was able to explain away the lack of reality. What really bothered me was, I think right before it, Whistler comes out with some sort of big firearm, then just stands there while a ninja knocks it out of his hands and slaps him in the face.
Again, I explained it away to myself (vampire ninja has superspeed, standing still was just meant to demonstrate that) but, even if that was what was intended, it just wasn't very well done.
They kinda do? In that there are distributed protocols where there's no distinction between a server and a host, but that kind of software doesn't optimize for mobile use well and the growth model tends to be more linear than the geometric scaling afforded to centralized services. =/

Its true there is a fan in the base of all bladeless fans, but the fan is smaller then traditional fan designs and moves the same if not more air then traditional fans.
Air is pulled in through the base and forced through a thin slit. This fast stream of air creates an area of low pressure, drawing in and amplifying surrounding air behind the slits.
Because air "sticks" to itself, when you get some air moving (by breathing out, for example), the initial bit of air that you move "drags" some air with it from beside and behind. This is what Dyson calls "air multiplier technology".
Dyson uses this property of air to claim that they only have to move a fraction of air (with the fan in the base) of all the air that blows past you.
Here is a example of how this works, and how you can use one breath to fill a large bag.
Here is a image of the multiplier effect, from the original intake of air at the bottom. You can see the air is multiplied from behind and infront of the fan.
still a miss-labeling to call them bladeless fans, just because the blades are hidden. by that logic my beef raviolis are vegetarian (tbf: the catholic church made a similar claim during the medieval ages).
Bernoulli Fan is not only more accurate, it also sounds much cooler.
To play devil's advocate, there are no exposed blades at the point of use. I'd wager people who buy "bladeless" fans are more concerned with aesthetics and avoiding a crying toddler than they are with semantic accuracy. We call Wi-Fi "wireless" even though the router is plugged in.
The cage had many iterations, the density of the cage increased and so the distance of the cage from the propeller. The propeller got replaced with a plastic one with rounded edges (though probably to save cost not as much for safety), so even if the cage is removed and you touch the propeller it isn't that dangerous.
I don't know what country you are in, and it is possible that in some place there might be dangerous fans, but if you can buy the bladeless Dyson, then chances are that stores also sell only modern fans, unless you're purposefully buying an antique somewhere.
at work we have expensive fans with a cheap metal mesh around them - to avoid a crying co-worker. at home i have a cheap tower fan with a weird plastic mesh - there are no visible blades on it except if i crank my neck into a really uncomfortable position and shine a flashlight into it. which one of the two can i call bladeless?
luckily i already have a devils advocate and @[email protected] dropped the name of god. how well do i need to hide my fans blade to create a Ventilationbescheißerle?
They are basically very large ravioli, but with a more German flavor (for lack of a better word). As far as I know, the origin story is more legend than fact, but it's a funny anecdote nevertheless.
Very tasty, I recommend giving them a try if you ever have the chance. Vegetarian and vegan versions are available BTW (at least in Germany).
Well, Beef comes from cows, and cows only eat vegetation, so beef raviolis are vegetarian. Now, I’m not a Rocket Biologist, but I think the math here is pretty conclusive.
beavers are also a funny thing: it swims, therefore it is a fish. fish aren't animal.
i was more referencing things like @[email protected] expanded: hiding meat in dough. funny how many strategies they had to cheat a supposedly all-seeing, all-knowing entity.
You know ... Bernoulli Fan - that's way better idea than a room full of MBAs from expensive business schools and months of market research and focus groups with 2 way mirrors ever came up with. Well done
There was time I was thinking too buy Tesla and willing to look past that in name of advancing EVs. That until I realized who he was (the thing in Thailand raised my eyebrow, then the covid, but my breaking point was when he sabotaged Ukraine's offensive). Now that finally seeing who he is made me wonder what I was thinking overlooking those things.
Fortunately I never pulled the trigger so I never owned any model. I still plan to have my next car and EV, but it definitely won't be Tesla.
To be fair the originals were cool. A small museum in my town has one on display and damnit if those roadsters weren't pretty cool (to me). Then the Nazi bitch bought the company and they started designing hot garbage.
Much like Sharper Image's Ionic Breeze, this is a very expensive bullshit tower, but I am seeing them everywhere lately. Box fans are fucking amazing. Get a box fan.
Of course they have benefits. Depending on the situation of course. I wouldn't put one in my computer, but I sure as shit have one in my home with a kid running around. Turns out a fan with all the heavy spinning hardware stuff in it's base is less likely to fall over than one with all that stuff up on top. Honestly all my Dyson stuff work fucking great for their intended purpose.
Paying the absolute minimal amount for something isn't necessary the goal of life. You're not a corporation.
Used to have to use one and I just don't understand the bagless appeal. I like having a bag to contain all this awful dust. Felt like I needed to wash every time I emptied it and they fill up so fast in comparison too.
And yet despite the fact that they're using less electricity and a smaller fan somehow the product costs five times as much as a normal fan. How does that work?
Partly because of the overall quality of the fan. Like you can go to Walmart and get a comparable bladeless fan for 49.99 but it's gonna be louder, won't be as efficient and won't last as long.
Speaking of the dyson. IMO one of the worst fans out there: extremely weak (see measurements on YouTube), extremely loud and very fragile...
Have one in the office, and I hate it...
A classic fan, fraction of the price performs better in all relevant categories...
Btw. They also create a "bigger" airflow around them so in that regard not better...
I got one years ago when they still were a lot cheaper and I must say it's the best one I ever had. It's powerful and so quiet that I can leave it running next to my bed when it's hot.
I have the opposite experience, have ypu tested competition at the same price level? IMO they're overpriced fragile plastic products with a very good marketing...
I mean now it doesn't matter anymore when you're satisfied, but before buying these overpriced fragile plastic stuff, I would at least test it against other fans. And surprise - almost all other fans work better and are cheaper, especially similar priced ones...
A much higher percentage of extra air will get pulled "down range" from a Dyson style fan. It's just that the air speed and total volume of those dysons are too low and they'd be noisy as hell to overcome it. But as a ratio of forced air to air that moves along, it's a much better amount than a traditional fan.
It's just some standard fluid dynamics. It uses "Bernoulli’s Principle" and the "Coanda Effect".
You can look up those, or probably look up those along with "dyson bladeless fan" to find a more direct explanation. The gist of it is that the ring of moving air causes a pressure drop inside and behind the opening that causes the air from further behind the ring to rush into the low pressure area and get pulled along through it.
I've never really understood this multiplayer thing, sounds like a free energy gimmick. You can move more mass at the same speed without putting in more power.
Basically they're trying to claim that the Bernoulli principle is some amazing concept that only they've come up with.
Their fans do work in the sense they do move more air but it creates so much back pressure that most of that air movement is lost. So you might as well not bother.
You're basically trading energy to move higher volume of air. The fan can move smaller amount of air at higher speed, but larger amount at a gentle breeze feels nicer and helps with circulating the air in the room better.
You could achieve it by taking that exact motor and slapping a bigger fan onto it, but that looks less cool and probably produces more noise? Maybe there's some efficiency differences if the motor is better at spinning fast, but as a spherical cow in vacuum it should be similar.
It's cheaper to make electric motor spin fast with low torque than slow with high torque, a ceiling fan of the same cfm needs a bigger motor than a standing fan.
Yeah, the fan being completely shrouded in plastic will dampen a lot of noise. And for the price, the fan is probably well balanced and somewhat optimised. From what I recall, the dyson bladeless fans are near silent.
So it's like a lever, you aren't just magically getting more volume at the same speed without more power, it just slows down when interacting with the outside air, ie conservation of momentum
Well in fluid dynamics you don't really make the distinction between liquid and gas. You can model air as basically just a very low viscosity fluid and it works. No one really knows why it works because it shouldn't, air doesn't stick to itself, but if you pretend that it does the simulations still work, even though they're wrong.
If you look in most physics textbooks even at quite a high level they will tell you that aircraft fly because air sticks to itself, but again, it doesn't. No one is quite sure why aircraft work, no one's all that certain where the lift comes from. But physics textbooks hate to admit that so they just pretend that air sticks to itself.
The whole air moves faster over the top than the bottom, why would it do that? It's not like the on the top of the wing and the bottom of the wing are connected by magic.
It's also possible to reduce perceived noise with some blade spacing tricks. I remember reading about how Apple designed the MacBook fan blades to seem really quiet under normal load. It was pretty interesting to read. I'm too lazy to find a link, but it should be easy to find with a quick search, if interested.
Yes. It's not necessarily the size that makes the noise, but rather the rpm required of the smaller fans to move an equivalent amount of air. I have a fan in my phone, for instance. It is so small that it spins at 23,000 rpm to make just a small amount of air movement I can barely feel, but easily hear. My ceiling fan can't be heard at all but still moves WAY more air while spinning at a couple hundred rpm. The air turbulence from blade speed is most of what you hear from a fan.
(I thought this was going to be about the guy dressed in a toga trying to sneak two of his friends into a showing of The Odyssey by hiding them in a little Trojan horse. (Worked until the horse tipped over and the two friends fell out.))
I remember going to the local waste dump about two or so years after the Dyson vacuum cleaner came out and seeing a shit ton of them in a shipping container. As I was throwing my rubbish away I asked a worker why and got the reply that a specific part inside always breaks so they put them all together and a company collects them to fix up as resell.
Which was a good thing to do, but I left there thinking, "yeah I'm not ever buying a Dyson anything."
I've not followed the company but it does seem that every time they bring out a product all they've done is reinvent the wheel and then marketed the shit out of it.
I wasn't a big fan of my wife proposing that expensive of a vacuum but ours has lasted longer than I thought it would. I believe we are on year 12 now and I've had to replace two parts (both were pretty cheap and easily found online).
We bought a Shark one when we moved and needed something and as impressive as the shark is, the Dyson can always find stuff it's missed.
Here's a pretty interesting vid on it. TL;DW Its a capacitor next to the motor that easily overheats and breaks. I hope whatever company it is repairing them also installs a better cap.
I did read somewhere that it was a plastic impeller type thing that would break due to the speed, not a capacitor. Though both can be true. Either way, thanks.

That may be a lemmy specific way to markdown
It's not Lemmy specific

how much could a marvel film cost? like $10?
Because the source material is bad.

It should
Aw... I really liked First Steps. One of the few genuinely artistic pieces of film to emerge from the Marvel Slop Farm since COVID.
I also liked it. Only gripe I have is Reed didn't get a whole lot of stretch time :^(
Pretty confident it's from Deadpool and Wolverine.
Can't believe I forgot about that. Best Blade movie since the original.

Regular fans dont have exposed blades either, there is a mesh over it.
I take it you've never seen a toddler stick their fingers through the mesh
Yes, I saw. The holes are small enough for an adult and far away from the blades for a toddler that it is safe.
My experience differs.
A lot of time came since we had fans like this: https://i.pinimg.com/originals/24/55/85/245585f84697075b625f5fff32089e07.jpg
The cage had many iterations, the density of the cage increased and so the distance of the cage from the propeller.

Honestly, I'd be half-tempted to buy one for a tiny fraction of the cost, just to build a powerwall out of the battery.
I saw some fully funcitonal going to less than 10k at one point
To be fair the originals were cool. A small museum in my town has one on display and damnit if those roadsters weren't pretty cool (to me). Then the Nazi bitch bought the company and they started designing hot garbage.
Yeah, I remember them wanting to open-source a lot of the design to help push electrics forward.
This is such a rollercoaster to read LMAO
A traditional fan also pulls air from around its blades using the same principal. A bladeless is just a gimmick it has no actual benefits.
Here's a video on the subject:
https://www.youtube.com/watch?v=ySSo5PmZZJM
It turns out, a bladeless fan is even less efficient than a traditional one. It works better, when you remove the casing.
Toddler hands don't go through the protection of a classic fan, if it's built like after 1965.
Also we were not discussing esthetics but efficiency.
Thank you.
Much like Sharper Image's Ionic Breeze, this is a very expensive bullshit tower, but I am seeing them everywhere lately. Box fans are fucking amazing. Get a box fan.
I did one better, I got myself a ceiling fan.
Of course they have benefits. Depending on the situation of course. I wouldn't put one in my computer, but I sure as shit have one in my home with a kid running around. Turns out a fan with all the heavy spinning hardware stuff in it's base is less likely to fall over than one with all that stuff up on top. Honestly all my Dyson stuff work fucking great for their intended purpose.
Paying the absolute minimal amount for something isn't necessary the goal of life. You're not a corporation.
None of what You said is about efficiency, which is the subject here. Not paying corporations for bullshit is one of my goals in life.
unironically love Lemmy for the explainers you get on a shitpost. Only stumbled on this cause I was looking it up myself. Thanks for the write up :)
Keep in mind, that the explanation is wrong.
Yep, dyson bullshit marketing.
Just like their hoovers then.
Used to have to use one and I just don't understand the bagless appeal. I like having a bag to contain all this awful dust. Felt like I needed to wash every time I emptied it and they fill up so fast in comparison too.
It's also just Dyson's completely overpriced bullshit. It makes weak air flow and has no real benefit for use as a fan.
Project Farm has tested them a couple different times. They're expensive aesthetic toys.
*Edit: While I'm on a bit of a Dyson rant; I'd just like to also say that I HATE their hand dryers that some places bathrooms use.
Works pretty well on my end
Any similar priced fan likely works better. Especially the fans seem to be garbage IME...
The dyson we use in the office is worse than the other fairly standard fan for a fraction of the price (airflow and loudness...)
It’s the same reason I use a beef bouillon cube in place of real meat when I feed my vegan friends. It’s much smaller so it doesn’t count.
My god, the sass - it’s magnificent.
And yet despite the fact that they're using less electricity and a smaller fan somehow the product costs five times as much as a normal fan. How does that work?
Partly because of the overall quality of the fan. Like you can go to Walmart and get a comparable bladeless fan for 49.99 but it's gonna be louder, won't be as efficient and won't last as long.

Btw. They also create a "bigger" airflow around them so in that regard not better...
Don't forget the fact that they cost like 400 plus dollars for reasons
Smaller fans = more noise
And why isn't a regular fan getting the "surrounding air" to move too? Is there a subscription for that?
It's most probably dyson bullshit (the moved extra air is slowing the original air down, or it's magic) marketing.
Magnets!
I got one years ago when they still were a lot cheaper and I must say it's the best one I ever had. It's powerful and so quiet that I can leave it running next to my bed when it's hot.
How much?
What?
HOW MUCH?
(Did you pay)
I don't really remember, it's been years. I think it was somewhere between 100-150€.
So 3-5 times a normal one... Kind of not cheap IMO, but if you like it...
I have the opposite experience, have ypu tested competition at the same price level? IMO they're overpriced fragile plastic products with a very good marketing...
Why would I test others when I already have one I'm completely satisfied with for quite some years now?
I mean now it doesn't matter anymore when you're satisfied, but before buying these overpriced fragile plastic stuff, I would at least test it against other fans. And surprise - almost all other fans work better and are cheaper, especially similar priced ones...
You're right, it doesn't matter
Yeah don't understand the hype for dyson, for (almost?) every category they have a product for there's a higher quality product for a lot less money.
They really seem to have perfected their marketing...
The products are not even high quality, thin fragile plastic everywhere...
The air thing is real physics. It does "work". It just isn't very useful in this application.
Sure it works, but it works for a basic fan as well, there is nothing special with the dyson variant.
A much higher percentage of extra air will get pulled "down range" from a Dyson style fan. It's just that the air speed and total volume of those dysons are too low and they'd be noisy as hell to overcome it. But as a ratio of forced air to air that moves along, it's a much better amount than a traditional fan.
Why would that happen? If you have some non-dyson source about that I'd be interested.
It's just some standard fluid dynamics. It uses "Bernoulli’s Principle" and the "Coanda Effect".
You can look up those, or probably look up those along with "dyson bladeless fan" to find a more direct explanation. The gist of it is that the ring of moving air causes a pressure drop inside and behind the opening that causes the air from further behind the ring to rush into the low pressure area and get pulled along through it.
Thanks!
I remember the Bernoulli effect from school :-)
I've never really understood this multiplayer thing, sounds like a free energy gimmick. You can move more mass at the same speed without putting in more power.
Basically they're trying to claim that the Bernoulli principle is some amazing concept that only they've come up with.
Their fans do work in the sense they do move more air but it creates so much back pressure that most of that air movement is lost. So you might as well not bother.
You're basically trading energy to move higher volume of air. The fan can move smaller amount of air at higher speed, but larger amount at a gentle breeze feels nicer and helps with circulating the air in the room better.
You could achieve it by taking that exact motor and slapping a bigger fan onto it, but that looks less cool and probably produces more noise? Maybe there's some efficiency differences if the motor is better at spinning fast, but as a spherical cow in vacuum it should be similar.
It's cheaper to make electric motor spin fast with low torque than slow with high torque, a ceiling fan of the same cfm needs a bigger motor than a standing fan.
I would counter that a small fan spinning at high rpm makes more (annoying) noise than a large fan spinning at a lower rpm.
But due to it being hidden maybe it can be isolated easier?
Yeah, the fan being completely shrouded in plastic will dampen a lot of noise. And for the price, the fan is probably well balanced and somewhat optimised. From what I recall, the dyson bladeless fans are near silent.
So it's like a lever, you aren't just magically getting more volume at the same speed without more power, it just slows down when interacting with the outside air, ie conservation of momentum
maybe it works kind of like how water works. Water also sticks to itself, like how separate droplets combine very fast when close enough.
Well in fluid dynamics you don't really make the distinction between liquid and gas. You can model air as basically just a very low viscosity fluid and it works. No one really knows why it works because it shouldn't, air doesn't stick to itself, but if you pretend that it does the simulations still work, even though they're wrong.
If you look in most physics textbooks even at quite a high level they will tell you that aircraft fly because air sticks to itself, but again, it doesn't. No one is quite sure why aircraft work, no one's all that certain where the lift comes from. But physics textbooks hate to admit that so they just pretend that air sticks to itself.
The whole air moves faster over the top than the bottom, why would it do that? It's not like the on the top of the wing and the bottom of the wing are connected by magic.
Fans are usually loud in proportion to their speed. Quiet ceiling fans have a big diameter and many blades. Doesn't a small fan cause a lot of noise?
Yep, which is why those Dyson fans emit an annoying high-pitched shriek.
Honestly depends on speed, quality of bearings and motor, blade geometry and thickness as well as any possible enclosures.
The biggest source of noise with fans is air cavitation.
It's also possible to reduce perceived noise with some blade spacing tricks. I remember reading about how Apple designed the MacBook fan blades to seem really quiet under normal load. It was pretty interesting to read. I'm too lazy to find a link, but it should be easy to find with a quick search, if interested.
Yes. It's not necessarily the size that makes the noise, but rather the rpm required of the smaller fans to move an equivalent amount of air. I have a fan in my phone, for instance. It is so small that it spins at 23,000 rpm to make just a small amount of air movement I can barely feel, but easily hear. My ceiling fan can't be heard at all but still moves WAY more air while spinning at a couple hundred rpm. The air turbulence from blade speed is most of what you hear from a fan.
I just imagined someone turning on a fan and hearing an electric f1 car drive by
But all in all:
i don't think the point of the post is about being useless or inefficient, but about the misleading name
Nothing sticks to my breath, especially in the mornings.
Oops! It's all fans!
It's OnlyFans!
If only.
Hey hey, no spoilers I haven't gotten to see The Odyssey yet!
I am not a fan.
(I thought this was going to be about the guy dressed in a toga trying to sneak two of his friends into a showing of The Odyssey by hiding them in a little Trojan horse. (Worked until the horse tipped over and the two friends fell out.))
Ionic wind generators also exist. Cool to have a particle accelerator but not very strong and catches dust (that's why they're called "air purifiers")
But it's bladeless on the outside, and that's what people care about.
That's totaly worth the $300 price tag that the OG Dyson one has cost when it was new.
Edit: they still cost hundreds of dollars. You can get any other brand's version for like $50.
I like the ones with dc motors. They are much quieter.
So are regular fans then, the blades are inside a mesh
Good luck creating one of those trendy diy air filters with a bladeless fan.
Remember losing all interest in the entire Dyson company when I realised this myself.
I remember going to the local waste dump about two or so years after the Dyson vacuum cleaner came out and seeing a shit ton of them in a shipping container. As I was throwing my rubbish away I asked a worker why and got the reply that a specific part inside always breaks so they put them all together and a company collects them to fix up as resell.
Which was a good thing to do, but I left there thinking, "yeah I'm not ever buying a Dyson anything."
I've not followed the company but it does seem that every time they bring out a product all they've done is reinvent the wheel and then marketed the shit out of it.
I wasn't a big fan of my wife proposing that expensive of a vacuum but ours has lasted longer than I thought it would. I believe we are on year 12 now and I've had to replace two parts (both were pretty cheap and easily found online).
We bought a Shark one when we moved and needed something and as impressive as the shark is, the Dyson can always find stuff it's missed.

Here's a pretty interesting vid on it. TL;DW Its a capacitor next to the motor that easily overheats and breaks. I hope whatever company it is repairing them also installs a better cap.
Interesting.
I did read somewhere that it was a plastic impeller type thing that would break due to the speed, not a capacitor. Though both can be true. Either way, thanks.
Yea they probably have multiple issues, considering these tend to be designed form over function so durability is likely sacrifced in many areas

I always thought it was a rotating, wide rubber belt. Maybe with fins. Idk
Surely that would work better. ?
And don't call me "Shirley."
I looked up the Dyson one and it uses a turbine rather than a fan, but it's effectively the same concept. The spinny part is in the lower part.
I probably saw a diagram of the Dyson one at some point and that's why I thought it worked like that.
