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

[–] [email protected] 76 points 1 month 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.

[–] [email protected] 43 points 1 month ago

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.

[–] [email protected] 43 points 1 month ago

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.

Apple has been doing that for years

They already do. My thinkpad T14s is incredibly thin, and it can dissipate ~~400~~ 40 watts of power. My P1 dissipates 160+ watts and it’s also very thin.

[–] [email protected] 8 points 4 weeks ago (2 children)

T14s

You mean 40W? Can't imagine a T config that'd do 400.

[–] [email protected] 6 points 4 weeks ago

Yes, single zero. 400w would indeed be VERY impressive.

This bad boy can do so much ~~crypto~~ AI

[–] [email protected] 5 points 4 weeks ago

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.

https://ventiva.com/how-it-works/

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?

[–] [email protected] 6 points 1 month ago (1 children)

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.

[–] [email protected] 8 points 1 month ago* (last edited 1 month ago)

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.

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.

[–] [email protected] 26 points 1 month ago (1 children)

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

[–] [email protected] 5 points 1 month ago (1 children)

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

[–] [email protected] 7 points 1 month 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

[–] [email protected] 19 points 1 month ago

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

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.

[–] [email protected] 3 points 4 weeks ago (2 children)

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.

That's correct.

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

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

[–] [email protected] 11 points 4 weeks ago* (last edited 4 weeks ago)

The "fan" sits inside a faraday cage.

[–] [email protected] 7 points 4 weeks ago (2 children)

I want to put one in a Valve Steamdeck.

Is this the same way those bladeless Dyson fans work?

[–] [email protected] 70 points 1 month ago (22 children)

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

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

[–] [email protected] 16 points 1 month ago

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

I'm more excited about those Frore MEMS airjet chips.

That's actually in at least one consumer product right now.

[–] [email protected] 4 points 1 month ago

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.

[–] [email protected] 3 points 4 weeks ago (2 children)

So my take away from all of this is that this is a laptop that can propel itself around in space. Pretty neat.
