            Looks like it’s specifically when an underscore follows a normal letter instead of whitespace. Not sure if that’s as intended by the markdown spec, incorrect in Voyager or unspecifed

            With underscores:

            normal_italics_ normal italics

            With asterisks:

            normalitalics normal italics

          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.

                Well, I guess I’m about to watch Blade 3 again.

                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.

    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.

    https://www.youtube.com/watch?v=rAAelB7nN14

    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.

          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?

        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.

      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.

      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:

      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.

      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.

      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?

        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.

    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”)
