Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.
Counterpoint: stop trying to make laptops thinner and implement realistic and functional air cooling
Passive cooling is generally better for reliability if you can make it work, since all active airflow systems will degrade as dust and hair works into the airflow paths.
Plus, the two can be used in combination. Improved passive cooling systems will make active cooling better by reducing the need to run the active system all the time, or at least run it at reduced rates, which will make the whole system last longer and reduce maintenance.
But this system still makes airflow right? Just without moving parts.
Or we innovate 🤷
It isn’t a given that every device needs a fan anymore. For example non intel MacBook air.
Make the chassis out of aluminium so the whole bastard is a heatsink.
Slaps roof of laptop This bastard can cook so many egg omelettes
Two eggs and one sausage
Apple has been doing that for years
My laptop and older phone has this and it really does help with the added surface area.
The only issue is if you go full throttle, the section right above the CPU can fry your hand lol.
Although I only ever reached that temp doing stupid crap like hashing.
Well there’s no shortage of those, and they’re unusually cheaper too (unless they’re specced out). I prefer a thin silent one myself, so I welcome this innovation.
Speaking from experience here, and limited information from the company, this looks like a polished version of a high-voltage grid accelerator.

What can be an expected concern is that besides ionizing air and imparting motion to neutral air molecules as the ionized ones rush from one plate to the other, that same effect can and will charge dust particles. That “collector plate” will need to be easily accessible.
Appreciate the link. I’ve got a hand-me-down Ionic in my house, and knowing that I can skip running it for basically the same effect means I can save a couple of cents on my electricity bill.
Gonna take another look at those IKEA tables with the HEPA filters built in. Those seem handy to avoid having to dust so often.
Sure thing, glad to be of some kinda help. Ozone can be a good irritant, never mind charged dust sticking to stuff it ordinarily wouldn’t.
I hope this company has a trick for dust control, but I’m expecting that’d be tougher than figuring out the ionic wind part.
They do have a solution for the ozone and dust problems. See this video at about the 9 minute mark:
https://youtu.be/fyai_kUYhLs?t=539
tl;dw: they’re using a cataylist to convert the ozone. There’s a lack of specifics on the dust issue, but they apparently have thought about it and have something there.
One other issue is that the static pressure is abysmal. You can work around that, but it’s not a drop in thing.
Not a fan
That’s correct.
It Fannot. Or it Fan’t.
Defanned
I think Dave2D made a video about those. He was cautiously optimistic.
Yes.
Doesn’t an ionic air moving system like this put out a big ass EM field?
Im a fabricator who don’t fuck with the lecky, but maybe someone more educated than me can explain why this doesn’t wipe your memory every time the cooling kicks on
The “fan” sits inside a faraday cage.
I want to put one in a Valve Steamdeck.
Nintendo Switch would be more compelling.
It would be a good use case; however, you can only do so much with a cut down version of a SOC that was originally made in 2015. It may be work for very little gains.
Is this the same way those bladeless Dyson fans work?
Bladeless Dyson’s have the fans hidden, as far as I know. But they still have a bladed fan in there.
Yes but they generate more airflow than the fan alone can
I recently watched some YouTube video that debunked that claim. They are basically pointless.
Edit: https://www.youtube.com/watch?v=ySSo5PmZZJM
It actually works better when You take the inner fan out of the casing. So they are actually a scam.
Not a dyson
Not a proper test, air volume not measured - only speed. The point is to not have fast air so this only confirms the concept works
Are you a Dyson salesman? Watch the video.
I sat through the whole ass thing
They do not. For a given power input they produce less airflow at lower velocity than a regular fan. They’re a complete scam.
Citation needed
You made a claim first, so you should provide your citation first as well.
https://electronics.howstuffworks.com/gadgets/home/dyson-bladeless-fan.htm
Air surrounding the edges of the fan will also begin to flow in the direction of the breeze. This process is called entrainment. Through inducement and entrainment, Dyson claims its fans increase the output of airflow by 15 times the amount it takes in through the pedestal’s motor.
Advertising for a product isn’t a citation. That article literally just repeats Dyson’s own claims. Do you have anything that actually tests that claim?
They’re “bladeless” fans are just regular fans with more steps. Those added steps introduce inefficiencies. Simple as that. If you wanted to make a fan more efficient, you could add a shroud close to the blades, but the energy cost of electric fans are already low enough that it really doesn’t matter.
They literally generate as much as that small fan in the case can generate.
With the aerodynamics of the case it’s just a matter of converting higher pressure into lower pressure with higher (& a bit more laminated) airflow.
I think you are talking about the Coandă effect.
I believe it’s called entrainment which is different?
They aren’t actually bladeless. The fan is just hidden in the base.
Those things have a fan with blades, just stuck in the base.
More like those Ionic Breeze air purifiers.
I’m more excited about those Frore MEMS airjet chips.
That’s actually in at least one consumer product right now.
I see what they did there with the “ICE9” name.
If it works, it sounds like it’d be something meant for a future Steam Deck to experiment with.
So my take away from all of this is that this is a laptop that can propel itself around in space. Pretty neat.
Sadly, there would be no reaction mass.
All that would happen is the lcd panel would boil and crack, and the processor would overheat soon after because nothing is carrying away the heat.
Nah, it can use all the dust and bits of carpet fluff. It’s magical stuff carpet fluff, it’s always a different color to any color you actually have as a carpet.
I have a house filter that functions on the same principal… Lol!
Hey! Are you crazy!!! You’re wearing pants while using your new iPad? Those pants club iPads in mere seconds! Try new silicone pants! Silicone pants are as clean as polystyrene without the downsides of other clean fabrics such as glass fabric! Get them at Walmart! Or get a new IPad Thin! It comes with a clean set including underwear, hair removal creme, pants, T-shirt and panties and bra for women. You can get a discount if you don’t want the unisex version. The I-condom comes included with Bluetooth.
… what?
