I have a fan from the sixties that I got from my great grandma. It has been running practically constantly for 10 years. Also have a great really old metal fan that has a laughable guard on it. Runs great and blows more air then any new fan of the same size. Build things right and they last a long time, companies want you to buy a new fan every year.
as far as I'm aware electric motors don't rly create a lot of stress on the bearings because they create a magnetic field to keep the bearings straight as opposed to the bearings on an axle for example being run by a drive belt from an electric motor because that axle is being affected by gravity
I found one of those old fans, I think mine was from the '50s. Metal fan blades, with a guard holes big enough to fit my hands through... i tested it & it worked. After a minute to clean the bearings it stated spinning oh so smooth! ...but since it was all steel, wired with a 2-prong cord wrapped in cotton, and could also be used to slice corn while still on the cob...it weighed too much and I was afraid to get near it me while powered.
@@Eis_ I did find my fan covered in dust & dirt in the back of on old farm barn where it had been abused & stored since the 1980s. Neglect seems like a good way to preserve this stuff, as long as it isn't stored outside. It cleaned up nice, with metallic blue paint & chrome preserved by the 1/8" thick crust of corn dust.
There's only one thing that comes to my mind: material fatigue. It's far easier to break something by bending it back and forth than by friction caused by turning. Grease is way easier to apply and therefore makes rotating machines arguably easier to maintain than periodic replacement of fatigued element. Not to mention the cost of manufacturing components that can withstand vibrations of that magnitude. We can flap our hands because our tissue is soft, deformable and rebuilds itself. Metal, plastic, even rubber, is rigid and cannot repair itself without external help.
@@gabor6259 They're called ornithopters, and the soft material part isn't the issue. They can be built with serviceable bushings and bearings. The issue is that the wings would have to be much larger and flap unrealistically quickly to generate a reasonable amount of lift. Ornithopters have been built, but they're unmanned due to very strict weight tolerances. They're mostly just impractical, though not necessarily impossible.
I’m a mechanical engineer and I work in data center cooling. We use liquid cooling and fan bearings wear out a lot on the dry coolers. I would love to see what kind of CFM these can produce.
He also made a misleading claim that a "waving" fan was essentially limited due to electronics rather than more accurately attributing the obstacles to mechanics. Electricity is just the power source. An electrically powered motor can do the "wave" motion, but may not be easily implemented onto a compact consumer product. This should've been his claim.

I have an oscillating fan that's at least 25 years old and works great. I'm 37 and my parents had it in the living room when I was growing up. Took it to college, and now it's in my workshop in South Texas.
@@paulallenscardsyeah I’ve been running my fan that’s 24 years old almost constantly for the last couple years and it still is running consistently and quietly pushing so much air…
Can't say the same for exauhst fans in industrial settings. A small oscillating fan isn't experiencing nearly the same forces as ones in industrial settings.
My question is how much maintenance has been done on it. That's a long time regardless but I would bet there's a good chance it's had some kind of maintenance.
Annoyingly nowadays we "could" make a lot of things last much longer than it used to but we don't because we're apparently hellbent on making cheap crap that'll break in the next week so you have to fix it or better yet buy a new one
You can avoid wear on things with material rubbing against another material. Use grease or oil. It lubricates the parts and protects them from wear over a long period of time. In an ideal setting, the lubricant is always changed on time, avoiding the wear and tear that comes from waiting too long to change it.
I found out that the best oil to use for motors in household appliances is chainsaw Bar oil. It’s additive free so it won’t gum up like WD40, motor oil or other silicone based products will. It’s also better to use in small electric motors like RC cars or drones that don’t have sealed bearings.
I installed a ceiling fan in the living room when I moved into my house five years ago. It has only been turned on once. I change directions seasonally. It's really well-balanced. I'm not seeing it dying, like, ever. But if it does, I'll update my comment.
@@hockeyguy820 afaik performance wise there's no significant difference with regular fan. But the form factor is way smaller so it would be useful for mobile devices
in fact they did have fans that moved back and forth instead of ceiling fans. The "fans" or wings? were moved back and forth by way of a connecting rod linkage to a slowly rotating gear motor shaft.
keep in mind, regular fans are great at moving lots of air, we only have very very small piezoelectric fans. they produce jets of higher pressure air however, so while two fans can have similar cubic meters of air moved, the regular fans air will be moving much much slower, but over a much larger area than the piezoelectric ones
anywhere flammable seems like a good idea. I saw a fan built on a power hammer motor that uses mercury bearings, like the old light house bearings, it was a beast and ran at high revs 24/7, last I checked the company (which works with all kinds of flammable fibres) is still going and using the same fan almost 45years later.
I think a more important factor is how small it can be. Imagine like 20 of these pulling air through tight hardware to cool it. I mean liquid cooling is probably more effective, but if you have some tech that needs to survive long term in a harsh condition this would be a good alternative to traditional fans
There’s actually a wall fan made by a company called Fanimation that uses the same back-and-forth motion, but the actual source of the motion still comes from a motor and then using a few hinges it attaches to a bar that moves back-and-forth that is attached to about five Palm blades that move back-and-forth
"Flapping" fans were actually a thing early 20th century. A theatre, say, would have rows of canvas sheet, that rocked back and forth, on the ceiling. The structure was something like canvas deck chairs, with actuating arms. A bit of clanking, but people in the tropics didn't mind.
It's true that an assembly where parts are rubbing together will wear out quickly. However most rotary fans use bearings, where the trapped elements (commonly steel balls) roll along the inner track as opposed to sliding across it
I took apart my fan because it was slowing down faster than expected. It was a simple brass "bearing". Rod goes through the brass hole and it simply rubs. The wear was minimal even though it has run for years.
@@jackykoningI rebuilt a few fans with those bearings. I learned that the oil they use in them, in the fiber packing, is solvent free oil. Oil like WD40 or motor oil has a lot of other solvents mixed in and will eventually gum up over time. The only oil that’s free of those additives, plus cheap and easy to get ahold of is Bar oil for chainsaws. One quart will service dozens of motors that use similar characteristics.
I've had the same box fan running in my room for the past 12 years. It has never been turned off unless there was a power outage. It still runs like new. Fans do not wear out "quickly"
@jackpfefferkorn3734 look, that'd fine if we're having a conversation about geology or trees growing, but in terms of fans? Decades are not quick by anyone's definition.
the main issue with these kinds of fans for certain applications is that, while they can move a fairly decent volume of air, they produce basically zero static pressure.
I am constantly replacing air curtains at work simply because people never clean them and they burn out. Anything that is dust proof that moves air will be huge.
i used to fix laptops and desktops, and fixed a couple old machines from factories or CNC shops, and those were the absolute biggest candidate for some kind of technology like this. if you could make an array that could effectively cool a standard rackmount chassis, you could immediately provide a useful solution for a number of machine shops
Unfortunately there are no material that can go through indefinite amount of bending like that. You can only bend stuffs so many times before they start cracking and finally breaking.
@@theboxofdemons but what the point? good brush-less fan outlives capacitors 100% already and would perform better and cost less than those little flippers. They just never put those in laptops.

In Indonesia, a fan has two type of fan motor which are bushing/boshing which are used in many fans, and the other one is bearing which is like boxing but instead there's a cylinder like thing on the motor as, as for fan like in the video it can stay for atleast 35 or 26 years (according to me)
There’s a study right now in new mexico I can’t remember why but they’re creating bird drones, if the phiezo crystals can support the weight of a bird’s wing it could work… maybe Edit: Ok, so I got more info on what they’re doing. They are using dead bird corpses that have been turned into taxadermy as the body of the drone. I don’t know why they need to be dead bird corpses but I assume they’re method differs from the technology mentioned by other commenters, or atleast has a different use? I don’t know, if people keep calling me out maybe I’ll keep doing more research to find the difference
Why not set them up like solar panels? Individual arrays of them on a large scale should produce the same results as a fan in theory right? Or am I missing something? 🤔
I've had the same Honeywell oscillating fan in my living room for over 5 years now. Still works great. Once a month, I take it to work with me. Using a carpenters square through the slats to keep the blades still. Blast it with compressed air. Clean as new 😅 It even still has the clear plastic film on the buttons. I try to keep the film on as long as possible to keep the area from being scratched up.
RC cars. My RC car has cooling fans on the motor, and the electronic speed control unit. Grass, dirt, tiny twigs, pebbles, and other things often get caught in the blades of the fans or even break the fan blades off. I don’t know if it would have a high enough output to effectively cool the electronics, but it’s worth a shot.
@ActionLabShorts These might be great for computers. Since it’s only one piece/“blade”, it would be monumentally easier to dust, and the random pattern it seems to follow would be great for keeping the whole area around it cooled, instead of allowing for potential hotspots in the PC. The biggest downside would only be how difficult it would be to get manufacturers on board with integrating this.
I've owned the same box fan since my parents got it for my room instead of getting me an aircon unit. It's lasted perfectly for the last 18 years. I'm very confident it will last for the rest of my grandchildren's lives.
Regular household fans use frictionless motors. They put a bearing between a copper spool. When electricity passes through the copper it creates a magnetic force that I turn spins the motor without material touching material. What you showed was a bearing. Which is not a fan.
I’ve used Honeywell fans for ages. Had one run for 7 years nonstop. Unplugged it one day, plugged it back in, it said “I’m tired boss”, and I let it go. It was a great fan. Money well spent.
I have an electric fan that belonged to my mom, it's older than I am.... I'm nearly 60! It still works great! I've never had a problem w/it!! CCC plastic fans I bought 1-2-3 years ago have already worn out!!
Regular fan will do just fine thanks..and tbh if this piazo crystal fan is low energy consumption then it might be a good idea to use it as cooling for a small electric devices.....also if they can be used in combination they might be able to move liquid opening up the idea for liquid cooling?
We have a fan at work made by a company called Dayton that has been spinning almost continuously since the 50s. We only turn it off to clean the blades every 6 months for about 15 minutes.
My parents bought a fan in 1989 when my sister was born during summer. The fan is still working perfectly fine ut to now, and now my sister owns it and used for her daughter who was also born during summer.
We have had anti friction bearings for many, many decades. They use ball bearings or tapered rollers that rotate instead of the very old style bearings that rub against things. Moving an object in a circle is much more efficient then accelerating an object in one direction, stopping it, then accelerating it back in the opposite direction. Also, a fan with an air foil blade would be much more efficient at moving air than a panel waving back-and-forth. Sorry to burst the creator's bubble, I guess he needed to show off a cool new thing somehow.
That would be good on flammable conditions, althought regular non brushing fans are also good. Maybe inside a fermentation chamber, at work we got to change our fans every year, but it would need to move a big amount of air
My Honda bike has moved its pistons up and down around 1 billion times (if you do the math) and it still works flawlessly. Don't tell me things that rub against each other wear out. If you manufacture them properly, they wear out so slowly, that from our point of view, they don't.
There was a company 2 or so years ago that was at one of the electronics conventions in LV. They had this tiny fan that came in 2 sizes and it could move some crazy amount of air using a fraction of the power that a conventional laptop fan uses. Pretty cool stuff. still waiting to see it pop up in a laptop. edit: just looked it up, it's Frore Systems
Of it can move water (antifreeze)than engine is perfect. First thing to fail in engine is water pump. Therefore it's replaced in regular maintenance. It's kinda complicated setup and pricey, so if you could install few of those flappy things in engine coolant system it would be beneficial
I think the real question is how much voltage is required for piezoelectric vs rotary . Either way this is an amazing piece of knowledge! Thank you for sharing! 🎉
That flapping fan in the video also require maintaining too. It rub itself against the air all the time when it move the air so overtime the friction still wear it down.
He’s referencing your home fan for comprehension, if you kept the fan running 24/7 then it would reach a critical point and a piece would break or wear down, but just so you understand the idea. The real issue with this is like the roller system at the beginning. Industrial systems and places that run nonstop, for factories and huge installations, and services like hotels and airports. These machines wear out way faster than anything you personally use at home. It’s actually a problem because they have to be so closely monitored, and stopped and repaired or replaced before they fail, and it means going through a lot of materials. That’s why we need better cooling equipment so that we don’t have to pump so much money and energy into simple maintenance of the cooling equipment on top of running the facility and doing the work that needs to be done.
😮🎉❤This is a very good invention for Fan. If normal Fan, if still be available after 100 years, means it was designed with 2.x times of Safety multiplied. Or in another word, it never runs in full load mode.😊
If we could make a scaled up version it would be great for speed boats because as a fish owner I know fins are more efficient at making thrust than propellers. So a imagine a speed boat doing 200mph with that
deep mineshafts air circulation is important and getting rid of the harmful gasses is as well but they need to work until the work is done without breaking down from wear and tear

I've been trying to tell you people for years now: Birds Aren't Real! This is the evidence!
FESTO ROBOTICS
Why not set them up like solar panels? Individual arrays of them on a large scale should produce the same results as a fan in theory right? Or am I missing something? 🤔
You said it yourself.
Birds
That's why watches have jewels. Because the jewels, sapphires and rubies, are harder than steel, and created little heat or friction.
Well here in arizona we broke the record for most consecutive 100+ degree days in a row so put it in my room
I've had the same Honeywell oscillating fan in my living room for over 5 years now. Still works great. Once a month, I take it to work with me. Using a carpenters square through the slats to keep the blades still. Blast it with compressed air. Clean as new 😅
It even still has the clear plastic film on the buttons. I try to keep the film on as long as possible to keep the area from being scratched up.
Living room tornado machine
Good use: my face after the coming in from outside during the heat of an Alabama July 😂
RC cars. My RC car has cooling fans on the motor, and the electronic speed control unit. Grass, dirt, tiny twigs, pebbles, and other things often get caught in the blades of the fans or even break the fan blades off. I don’t know if it would have a high enough output to effectively cool the electronics, but it’s worth a shot.
they don’t rub bit they flex. same problem
I think you are giving these things way more credit than they deserve.
Well done! It turned out beautifully. One day I’ll attempt this style again!
A good use is helping cool my house. And I'm glad you straightened out why planes don't flap their wings, that was pretty good..
who needs school when you have this guy?
@ActionLabShorts
These might be great for computers. Since it’s only one piece/“blade”, it would be monumentally easier to dust, and the random pattern it seems to follow would be great for keeping the whole area around it cooled, instead of allowing for potential hotspots in the PC. The biggest downside would only be how difficult it would be to get manufacturers on board with integrating this.
It's always fascinating to hear about things that are completely trivial and easy for us, but that are super complicated for machines.
I can't think of a better use than cooling me down specifically
I've owned the same box fan since my parents got it for my room instead of getting me an aircon unit. It's lasted perfectly for the last 18 years. I'm very confident it will last for the rest of my grandchildren's lives.
I've never once in my life seen a worn-out fan. Today's my 45th b-day.
It would really be useful if leaf blowers or others could use that technology
I feel smart. That was my first idea at the beginning of the video.
Regular household fans use frictionless motors. They put a bearing between a copper spool. When electricity passes through the copper it creates a magnetic force that I turn spins the motor without material touching material. What you showed was a bearing. Which is not a fan.
They used piezo injectors in diesel engines. No need to say they wore out much faster than regular non common rail diesels
I’ve used Honeywell fans for ages. Had one run for 7 years nonstop. Unplugged it one day, plugged it back in, it said “I’m tired boss”, and I let it go. It was a great fan. Money well spent.
I have an electric fan that belonged to my mom, it's older than I am.... I'm nearly 60! It still works great! I've never had a problem w/it!!
CCC plastic fans I bought 1-2-3 years ago have already worn out!!
Regular fan will do just fine thanks..and tbh if this piazo crystal fan is low energy consumption then it might be a good idea to use it as cooling for a small electric devices.....also if they can be used in combination they might be able to move liquid opening up the idea for liquid cooling?
We have a fan at work made by a company called Dayton that has been spinning almost continuously since the 50s. We only turn it off to clean the blades every 6 months for about 15 minutes.
Dude, you always find the most interesting things. So cool.
My parents bought a fan in 1989 when my sister was born during summer.
The fan is still working perfectly fine ut to now, and now my sister owns it and used for her daughter who was also born during summer.
If I was your editor, I woulda popped off when you said “plane’s don’t flap their wings like a bird”
Those fans would be PERFECT for making a video showing people that those fans exist.
We have had anti friction bearings for many, many decades. They use ball bearings or tapered rollers that rotate instead of the very old style bearings that rub against things. Moving an object in a circle is much more efficient then accelerating an object in one direction, stopping it, then accelerating it back in the opposite direction. Also, a fan with an air foil blade would be much more efficient at moving air than a panel waving back-and-forth.
Sorry to burst the creator's bubble, I guess he needed to show off a cool new thing somehow.
I have a fan my family bought from the 90s and it's still a tornadomaker spinning nonstop 24/7 (except for going out).
EVERYONE, and I mean everyone in New Mexico needs these kinds of fans
I could imagine the "plat plat plat plat plat" noise that this would make if it was installed in a confined space.
My grandparents have had the same ceiling fan in their living room for like 65 years. I've never seen a fan break.
the urge to put my finger there and see what will happen is insane
That would be good on flammable conditions, althought regular non brushing fans are also good. Maybe inside a fermentation chamber, at work we got to change our fans every year, but it would need to move a big amount of air
My Honda bike has moved its pistons up and down around 1 billion times (if you do the math) and it still works flawlessly.
Don't tell me things that rub against each other wear out.
If you manufacture them properly, they wear out so slowly, that from our point of view, they don't.
The plane flapping it's wings made me giggle
There was a company 2 or so years ago that was at one of the electronics conventions in LV. They had this tiny fan that came in 2 sizes and it could move some crazy amount of air using a fraction of the power that a conventional laptop fan uses. Pretty cool stuff. still waiting to see it pop up in a laptop.
edit: just looked it up, it's Frore Systems
My ceiling fan is old enough to drink. "Quickly" must be relative.
I’ve had my fan for about 9 years now and use it may-September and it’s not had any issues so far
Of it can move water (antifreeze)than engine is perfect. First thing to fail in engine is water pump. Therefore it's replaced in regular maintenance. It's kinda complicated setup and pricey, so if you could install few of those flappy things in engine coolant system it would be beneficial
You got me thinking about a plane that just flaps its wings like a hummingbird and it cracked me up
I think the real question is how much voltage is required for piezoelectric vs rotary . Either way this is an amazing piece of knowledge! Thank you for sharing! 🎉
Low profile GPUs and laptops cooling, that would be cool
I’ve had my ceiling fan fun constantly for like 4 years now
That flapping fan in the video also require maintaining too. It rub itself against the air all the time when it move the air so overtime the friction still wear it down.
He’s referencing your home fan for comprehension, if you kept the fan running 24/7 then it would reach a critical point and a piece would break or wear down, but just so you understand the idea. The real issue with this is like the roller system at the beginning. Industrial systems and places that run nonstop, for factories and huge installations, and services like hotels and airports.
These machines wear out way faster than anything you personally use at home. It’s actually a problem because they have to be so closely monitored, and stopped and repaired or replaced before they fail, and it means going through a lot of materials.
That’s why we need better cooling equipment so that we don’t have to pump so much money and energy into simple maintenance of the cooling equipment on top of running the facility and doing the work that needs to be done.
We've had our bedroom fan for 8 years. Going strong.
I've been waiting for laptop fans using piezoelectric tech for years now.
sounds like we finally figured out how to make the ornithopter from dune come to reality
😮🎉❤This is a very good invention for Fan. If normal Fan, if still be available after 100 years, means it was designed with 2.x times of Safety multiplied. Or in another word, it never runs in full load mode.😊
If we could make a scaled up version it would be great for speed boats because as a fish owner I know fins are more efficient at making thrust than propellers. So a imagine a speed boat doing 200mph with that
Replaceable electrical cooling hardware!
deep mineshafts
air circulation is important and getting rid of the harmful gasses is as well
but they need to work until the work is done without breaking down from wear and tear
Ive had a desk fan thats been running almost 24/7 every summer for 8 years
Very excited to see this tech in laptop cooling
