I mean, technically you can convert electricity into "cold" using extremely precise laser frequencies and atomic resonances to convert thermal energies into photonic light.
Cooling a CPU using this method is probably overkill.

He truly has nothing to lose. Probably has a massive saving account protected from his business finances so he can just dick around with a billion dollar company, thousands of people's livelihoods, and if it goes tits up he is still a rich asshole.
Not surprised at all that he is clinging to this.

"No."
My least favorite way to start a reply. Especially when wrong. Which you are.
Also electricity directly into cold? Sounds like a violation of the first law of thermodynamics. Some heat must be dumped somewhere.

You have thermoelectric and piezoelectric mixed up.

>from 100% usage to 99%
Isn't that just disabling turbo/boost clocks?

You're thinking of the peltier coolers. The piezoelectric fans that they are mentioning are the ones that vibrate like you mentioned

Laptops can get pretty hot these days. However reducing the Cpu usage through Power setting helped massively dropped down from 100% usage to 99% and the temps went down from 101°C on max fan speed to 78-79 on default and as low as 70-69 with max fan speed.

Hmm. Looks like it might work on a similar principle to those piezoelectric fans LTT did a video on a while back. I'd be very interested in seeing how they arranged the oscillators to pull air through like that.
Really there's a lot of technical information about the design that the article really doesn't go into. I'm also interested in the heat exchanger, since I would imagine they're generating comparatively lower airflow but also making everything very compact.
Kind of excited to see if thia goes anywhere.

The big question is how they handle dust

This is probably a concept that “will” take off. Maybe not for awhile though. If they have a basis for how to do it at scale, and adapt to the market, they will be well positioned.
I think Apple will probably kick off widespread adoption of AR/VR.
That being said, no one wants to have their data skimmed by Meta.

It creates a gradient. One side hot, one cold. It helps to move heat away from the cold side but overall it net generates heat.
