Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.
Ionic acceleration of air needs high voltages and the air gets ionized (the reason people recommend against vacuuming a PC). I’m surprised that it works at all in close proximity to sensible tech.
Edit: right, low static pressure, meaning: lower voltages. But still not low.
They use a grounded faraday cage around it. Video on it where he touched on that https://youtu.be/fyai_kUYhLs
He just mentions they have a solution but it’s patented so they wouldn’t talk about it. Take that as you will of course
the reason people recommend against vacuuming a PC
A regular vacuum isn’t doing anything with ions or high voltages. Moving air can generate potentially harmful static electricity, but usually the reason people recommend against vacuuming a PC is because if you spin the fans doing that, the motors inside turn into generators and drive current back into your PC parts that could damage them.
Moving air can generate potentially harmful static
Well, and what do you think creates that static electricity? Ionization.
Feeding back electricity, that’s why motors usually have a diode or something.
The difference between a vacuum and this fanless cooling device is that a vacuum happens to generate a small amount of static, and usually has grounding wires in the hose to prevent it shocking things, while this fanless device is intentionally ionizing as much air as possible to get it to move.
Uuuh, the cooling in macbook airs and ipads is just passive aircooling, like in all phones and all other “normal” tablets.
There’s no rule against using active cooling for tablets and phones, only practicality. This technology seems like it might be practical enough to use in compact devices such as those, but we’ll see if that’s true.
I’d be surprised if they can keep phones with this waterproof and dust proof. Laptops I can see, phones not so much.
Sadly, this won’t go anywhere now for the same reason it didn’t go anywhere for the 10 times it has been proposed before. It looks great on first look but longevity is amazingly low and likely will require purchasing of catalyst less than a year after first use. I’m sure investors loved that part of the pitch but compared to current fan tech, with good static pressure, there’s no way someone with half a brain would chuck this in their laptop. And that’s before considering the rest of the downsides.
Highly suspect this account is part of some kind of influencer marketing bundle. On lemmy, such amount of upvotes for a completely wrong post is unusual given the population around here.
It uses an MnO2 catalyst plus a non disclosed tech which will absolutely not last a year if the laptop is used for anything more than web browsing or happens to be used, you know, on your lap.
Looking forward to be wrong on this one, except, I won’t.

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.
I recently watched some YouTube video that debunked that claim. They are basically pointless.
I think you are talking about the Coandă effect.
They do not. For a given power input they produce less airflow at lower velocity than a regular fan. They’re a complete scam.
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.
