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

[–] socsa@piefed.social 75 points 3 months ago (2 children)

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.

Or we innovate 🤷

It isn't a given that every device needs a fan anymore. For example non intel MacBook air.

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.

Sound familiar?

I think Dave2D made a video about those. He was cautiously optimistic.

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.

Is this the same way those bladeless Dyson fans work?

[–] MangoPenguin@lemmy.blahaj.zone 16 points 3 months ago

Those things have a fan with blades, just stuck in the base.

[–] Bezier@suppo.fi 34 points 3 months ago

They aren't actually bladeless. The fan is just hidden in the base.

[–] ptz@dubvee.org 1 points 3 months ago

More like those Ionic Breeze air purifiers.

[–] dabaldeagul@feddit.nl 70 points 3 months ago (1 children)

Bladeless Dyson's have the fans hidden, as far as I know. But they still have a bladed fan in there.

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.

[–] catloaf@lemm.ee 6 points 3 months ago (3 children)

What catalyst? There's no chemical process here.

[–] Viri4thus@feddit.org 4 points 3 months ago (1 children)

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.

Oh, to compensate for generated ozone. I suppose that would depend on how quickly it's depleted.

[–] SzethFriendOfNimi@lemmy.world 3 points 3 months ago

Possibly to deal with the ozone things like this can produce.

[–] MonkderVierte@lemmy.ml 46 points 3 months ago* (last edited 3 months ago) (5 children)

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.

[–] AtHeartEngineer@lemmy.world 26 points 3 months ago (1 children)

They use a grounded faraday cage around it. Video on it where he touched on that https://youtu.be/fyai_kUYhLs

[–] RubberElectrons@lemmy.world 5 points 3 months ago (1 children)

Can't watch the video rn, anything about the dust problem?

[–] Chronographs@lemmy.zip 7 points 3 months ago (2 children)

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

[–] RubberElectrons@lemmy.world 19 points 3 months ago

Strange, patented means it should be findable on the USPTO system, diagrams and all. And yet..
