Under non gaming loads (for me, that's mostly web, iOS development in Xcode, and streaming movies/TV) the M1 Air barely ever gets even slightly warm.
No, they can't put a bigger battery. The 16" MBPs already have a 100 Wh battery, which is the maximum size allowed by the TSA [1].

The market for that is minuscule, and they likely can't make a solution that works universally for every laptop.
Why? They should be able to acquire purchase agreements and startup investment on the strength of the product.
My brother in christ, have you heard of the patent system in general?
Try starting a new phone or laptop company. Your step 1 will be to acquire a patent war chest, so if someone sues you for patent infringement (and they will), you can sue them right back for the same.
In this world, if that company is for sale, someone much bigger is going to buy it, and make their technology their own exclusive. Be it Apple or Samsung or whatever. Getting hands on this tech _so your competitors don’t_ would also be a valid reason for acqusition.
Also, could a hacker build something like this (but likely much less efficient) at home by taking apart a DLP video projector and playing a carefully constructed video loop on its micromirror (https://en.wikipedia.org/wiki/Digital_micromirror_device)?
However, the marketing images on the product page don't match with this; there's definitely a lot of images of use at home. I'm not sure whether it's a consumer product or not.
The fact that hasn't happened, either means the product has a big downside (eg. stops working after 1 hour use as it blocks with dust), or because the manufacturer is offering silly terms.
I suspect it’s more of a “does it work, how does it hold up, and can they scale to our volumes/heat levels” question.
The fact they could hack this is still interesting. Fun to watch.
It would be nice for consoles and other living room electronics. My PS5 fans are annoyingly loud.
The downvoting anything critical of Apple is getting ludicrous. Maybe you believe they are a benevolent user-loving company who always does what's best for their users regardless of how it affects their business, but viewpoints who don't share that position aren't automatically wrong because they have a different opinion than you. Skeptical people are what built the hacker community. If you don't want to embrace that spirit, at least don't try to silence it.
Edit: And yes, whether Apple would want this or not is very relevant, because if you read the article, they do not sell to consumers. The only customer for this would be Apple, and having Apple buy their product and put it in macbooks is the strategy they are pursuing.
2) it's not critical of Apple
To quote Doc Brown, "you're not thinking fouth-dimensionally!" It was when I posted the original comment.
This is unintentionally funny, because the law of fans is that the smaller they are, the louder they have to be to achieve the same cooling.
Air moved is a function of blade size and speed (and shape and count and more, all applying to big and small fans ~alike) — and those two are indirectly proportionate. The smaller the blade, the faster you have to spin it. The faster you spin, the more turbulence you make, the more sound you get.
Biggest hack for silent active PC cooling is to use upsized fans spinning slower (see Notcua).
The PS5 is fairly loud, but the noise is quite directional - it's much louder from the rear than the front. By keeping all of the vents on the front and rear of the console, it can work effectively inside a TV cabinet or media center that would suffocate an Xbox. It's not the set of tradeoffs I would have preferred, but it isn't a thoughtless design.
Seems like a harder sell as an off-the-shelf component. I wonder if they're angling for an acquisition (by apple or otherwise)
> AirJet isn’t a consumer product–consumers can’t buy it and modify their own MacBook Air, nor does Frore plan to create a kit for consumer sale.
This is aimed at Apple, and he doesn't want to offer it for sale? Acquisition.
I get that it's a new product that requires good engineered integration to really show off how amazing it is, so they want to start with some flagship products... But if Frore Systems starts treating the airjet like it's a secret sauce to be slowly doled out to manufactures it'll just make me suspicious of their claims and the airjets real world usability.
Piezoelectric cooling doesn’t cool air so there’s no chance of condensation.
Don’t judge if this is a very stupid question - about to buy a MacBook Air to substitute an M1 Max for travel.
Removing that heat should be beneficial either way.
both of those are way less efficient than something that cools the chip directly
I'd love to get this Airjet thing installed in it to see if it makes a difference.
This "airjet" is a kind of almost solid state fan using membranes to generate airflow. They may be able to perform similarly to normal fans with less noise and a smaller physical footprint, but they still need to get that air moving through a heatsink somehow. I don't think it'll work for laptops that are designed to thermal throttle after a few seconds.
I jumped to a 16" M1 Max that I found at a pretty decent sale price. You won't regret it if you can swing the cash. The fans have only turned on when I've played Civ 6. I think they maayyy have turned on during Lightroom use but I'm not so positive.
It's said because my old 15" still operates, hardware wise, without any issues. I plan to turn it into a linux or a windows machine to play other old computer games.

Or, switch to Linux and use mitigations=off.
Just get an M1 Air on sale, second hand, or refurbished. It will be night and day.
Air gets warm only with some long compiling.
So now if Apple is well ahead of the competition in power efficiency, and if, on top of that, the Aijet is really a revolution in (silent?) cooling, then we have here a maximization of the value of all those Ghz.
As an amateur computer musician, this is exactly what I need: a continuous silent performance at a "budget" price.
The other is Apple chips target a lower clock rate than Intel and AMD do for laptop chips, this is a tradeoff. You get better perf/watt at lower clock rates, and a lower targer design can be smaller[1] and lower power. OTOH, you miss out on the top end of performance for those willing to power and cool the beast. It's a good tradeoff for Apple, who never provided ample cooling for their Intel based laptops, but it's hard to market for Intel and AMD when PC laptop makers do want to sell some devices that can clock to the moon all day if users want it. AMD is expirementing with their compact cores as power efficient cores in some laptop skus, so we'll see something there; Intel is going with the BIG.little approach of less capable little cores, rather than just clock limited little cores.
[1] see AMD's Zen4c which is about half the size as a regular Zen4 for the core+L1+L2, L3 cache footprint remains the same for a given size
You can try running these chips at their boost clock all the time by attaching coolers, but the hardware wasn't designed for that and neither was the software. It's easier (and more power efficient) to clock down if you care about maintaining a set speed. With a battery capacity designed for short bursts, you'll also lose out on battery life if you decide to crank the hardware.
The Macbook Air and its competition (MS Surface etc.) are completely silent because they are fanless, and I don't expect their performance to be inadequate for anything but the most CPU intensive tasks. The Airjet will add some airflow, so while the difference may be minjmal, it'll always end up louder than before.
I understand how you could have a bunch of membranes that vibrate ultrasonically -- it's basically an array of miniaturized audio speakers. What I don't understand is how any localized oscillation of air gets transformed into massive, consistent air suction in a single direction.
I can vaguely imagine how valves might work, but I'm still curious how they do. I looked at the linked patent applications but the descriptions seem way too complex and abstract to get any kind of intuitive sense of the mechanism without already being an expert.
There's a related video they link to: https://youtu.be/NY-gA_zA_os?si=9ULOds_TqUO56MGs which demonstrates one type of piezoelectric fan, but it seems to be operating on totally different principles -- one end is freely swinging, rather than a membrane with fixed edges oscillating. And there are definitely no valves involved in that one.
Is there anywhere else that explains how oscillating membranes generate smooth airflow?
Hope that helps!
The reason I asked is because this is sick, unless it makes my dog cry.
