This tech is absolutely incredible and I think it will change the industry

1) Ionic thrusters suffer quite a bit of material degradation.
2) There is a chance of electric shock if not properly gaurded.

Dust is the undefeated destroyer of solid state coolers.

[soliton]

very positively surprised that you mention the ozone problem. so many youtubers that make videos about ionic air movers dont even seem to know that problem exists. thank you!

[PlasmaChannel]

I love your enthusiasm about ionic thrust! Thats exactly how I feel about it honestly. Have to say, your breakdown on this topic is phenomenal. I've had viewers for years ask about using ionic thrust in computer cooling and i've personally advocated against it, as ionic thrust still tends to have ionic residuals, which can interact with sensitive components. Apparently ventiva has worked to reduce this? Great video!

[boltvanderhuge]

Any amount of dust will drastically reduce the efficiency, and just a few hairs could short it entirely.

[sebastianborusinski]

Ozone generation is not the only consideration. NOx are formed as well, much more toxic and, even worse, corrosive towards copper heat exchangers (a.k.a. radiators). Question is, how much will it produce?

[Humtog]

I am from future. My laptop just failed the mandatory yearly pollution test...what to do!!

For anyone who is curious about the reupload: I watched the whole old clip and there were a lot of `missing media` screen, potentially when he was trying to show some figures.

[Pyroteknikid]

This is not new technology. We had ionic fans 20 years ago.
Can the cooler be removed for cleaning? The electrodes will attract dust and start arcing over eventually.
Unlike a traditional fan, a dirty ionic blower will cease to function entirely.
Also, these things create absolutey zero static pressure.

[eyeball]

Oh, it's just a small ozone generator.

[alexandersanchez]

Yeah, I'll pass on generating ozone+NOx and risking serious shock, not to mention my fan failing silently as the material degrades after ionization for a long period of time.
I don't see this to be a viable replacement at all, even if you could make this more efficient, the benefits don't offset the drawbacks enough.

The piezoelectric device generates enough static pressure you can use hepa filters, meaning you can make incredibly well sealed devices with almost no particulate ingress.
If they can improve efficiency then I think piezo is the way to go.

At 6:01 I think it is written Dell on that surface

[AnyFishKiller]

Ozone, nox, dust…sure. I’m just worried if it’s constantly going to build up static electricity everywhere around me. That’d be annoying😂

Bladeless magnetic ionized fans have been around in the mining industry since the 1970s for emergency airflow situations in, and supplemental airflow in conjunction with overcast/undercasts for decades. They were used when the working area was too far away from the intake or exhaust fan to have proper airflow especially in Shaft or slope mining operations that were miles away from the fan or for longwall mining. I was always surprised no one tried this before now, but I always thought that maybe it was because of the size and it being so small that it would be hard to produce or the magnetization would not be at an acceptable level in a few millimeters of width. Sometimes industrial level technology can't be scaled down because of output losses but this seems like a great idea. Its time the computer industry started looking at new way of doing things since computers haven't really changed in their fundamentals since the 1980s. Fans are a good start to rethinking the computing paradigm.

[Chamieiniibet]

Frore's device is(was?) not just about producing the airflow, it's about breaking the surface layer that makes standard radiators' magnitudes of order less efficient than it could have been. And that offsets a lot of the perceived inefficiency in the flow generation.

[HannesMrg]

No moving parts does not necessarily mean that it lasts longer. The high voltage can be a big stress in the electronics of the fan, but also can mean a lot of noise that the other Components need to endure.
Similar to good quality LED lights. The LEDs themselves rarely fail, but often it's the driver circuitry.

[TayoTheT]

I don't think comparing energy to air volume per time is completely the same as energy to heat removal. With piezoelectric coolers they are able to hit really high pressures, meaning they can remove a lot more heat with much less volume. Like, a breeze outside could be thousands of CFM, but obviously a CPU would overheat. Only the air in contact with the surface you're trying to cool is what matters, and the higher the pressure, the less volume you need. If you had infinite pressure, you'd only need one atom's width of air to cool something.

[ceebee]

This tech isn't new. 25 years ago you could buy cheap "fanless" air filters from Walmart that used the same ionization process.

[NXaiUL]

Sorry for being pedantic but "1 watt of energy" is incorrect.

Watt is a unit of Power.
Watt.Hour is a unit of energy.
