I'm answering the important questions.

How much thrust does a ceiling fan produce?

YouTube
@TechConnectify These truly are the important questions. Very excited for this one
@TechConnectify Could someone please explain the opening architecture joke?
@gudenau @TechConnectify Not sure if this request is sincere but here goes nothing: Somebody who is into architecture might also be interested in ceilings, I.e. the person is a fan of ceilings, hence the joke that there are ceiling fans at such a convention.

@laubblaeser yes but also "to put up" is another word for "provide accommodations" (as in, "Chris needed a place to stay so we put him up for a bit")

my best jokes have layers

@gudenau @TechConnectify architects are fans of (like) ceilings.
@TechConnectify can't wait for the annual Christmas Light video!
@TechConnectify next: how fast a ceiling fan must spin to hover?
@cos
Wouldn't is fall over first?
@TechConnectify
@minecraftchest1 @TechConnectify make it dual fan setup so it'll be stable without tail rotor.

@TechConnectify Bravo. You did it. You finally embodied low effort. You didn't convert to metric, you taunted cookie forces, and you passed a lot of the hard work onto another person.

I'm so proud of you. :3

@TechConnectify That is more than thrust of many spacecraft thrusters!
@jajcus ...except those also work in a vacuum ...

@SvenGeier @jajcus they work in a vacuum by spewing non-vacuum out the back.

If you spew non-vacuum at a fan in a vacuum, it'll probably also work.

@TechConnectify I love your no-effort november! Why not a no-effort all year? IAHAHAHahahaha :)
@TechConnectify I know this is No Effort November and all - but we are all indebted to your tireless persuit of truth. Thanks! Hmm, I wonder what it would take (in terms of weight reduction and power increases) to get a ceiling fan to be an rc helicopter? For another month, I guess. :-)
@TechConnectify Would love to see a collab between you, Randall Monroe and Adam Savage on how much power does it take to launch a ceiling fan. :-)
@TechConnectify I love your videos. I always learn stuff, even during No Effort November. The one about freeze-drying was fascinating. You do a great job. Thank you for the content.

@TechConnectify You know, I had this question as well, but as I have always done when I do any electrical work, I looked up the electrical codes for hanging ceiling fans (in Ontario at least) and the requirement is for the electrical box to be secured on two sides at least, but I do think that most home installs involve just replacing the existing light figure which probably doesn't meet that requirement.

Oh...and a super weird thing about Netherlands (probably European) electrical figures...they don't have electrical boxes to screw to in the ceiling...you just mount directly to the ceiling or wall...so weird.

@TechConnectify Since the fan is so close to the floor, the ground effect could also play a role.
Ground effect (aerodynamics) - Wikipedia

@leckse @TechConnectify

I find it interesting you point out ground effect, when you don't point out that they're designed to be mounted much closer to the ceiling than they actually are to the ground in the testing apparatus.

@ironhydroxide @TechConnectify This is not equivalent. A fan will blow air in a particular direction, but it can’t draw air in from a particular direction. It’s just air pressure equalizing.
@leckse @TechConnectify and funny enough, some fans are reversible as shown in the video. Which means yes, it can make as much (or more) difference than being as close to the ground as shown.
@TechConnectify for the sake of absolute pedantry, all torque is "twisting" 😝
@TechConnectify “Which is a different number in kilograms.” 🤣Love it!
@TechConnectify
Now I want to replace a ceiling fan with a helicopter tail rotor…
@TechConnectify but what about Bernoulli's principle?
@TechConnectify This was great. Loved the helicopter and metric measurements.

@TechConnectify aaaa AAAA <procesing processing processing> OOOver the rainbBOW!

Well done.

@TechConnectify but does it pull away from the ceiling when set to reverse?

@TechConnectify two weeks ago I thought about buying a ceiling fan. Because cold floor and heated air on my ceiling doesn't warm me.

Yesterday you published that no effort video.

Love it. 👍🤗

@TechConnectify Do a Whirlpool washing machine video and how they work. A video for reference...

@TechConnectify great!   . I’m going to watch it at night.
@TechConnectify It's interesting comparing how much less contrast in in your videos today compared to your older videos. I know it's in vogue right now but I kinda miss the contrast!
