They claim 75% better. I doubt this is better than compressors in general but they seem to be going for a niche where a high power compressor does the high load part but when only a litte cooling is needed the compressor is now very inefficient and so the peltier is better. Normal fridges just let the temperature have a wider swing which is good enough for most needs.
> Normal fridges just let the temperature have a wider swing which is good enough for most needs. These wide swings annoy me. You hear that you shouldn't let your fridge go above 4°C, because that's dangerous. And you obviously don't want your fridge to go below 0°C. But finding a setting where the hottest part of the fridge doesn't go above 4°C (or even 5°C or 6°C) during the hottest part of the cycle and the coldes…
I think the 4C recommendation is an average. There is not magic in ~1% temperature difference from 3 to 6. Just slightly different rates. Which again slow, but do not stop when it is at low end compared to high.

#194I remember back in 2006ish, my PC modding days, buying some peltier modules from eBay and (attempting) to get subzero temps out of my CPU cooling.
If I recall correctly I got the setup powered but stopped short of actually putting it on my CPU when I couldn't mount it all in a way that would let me contain the condensation with what I had.
Maybe it was pccooling or pccasemods dot com? There was a really strong community forum back then where it was all going down, people were nitrogen cooling their PCs, watercooling was a big deal, and CPU temps of 60c were considered unsustainable.
I still overclock my computers but usually my aim is a silent computer under 60% load, so my goals have changed. Peltiers are not something I see taking over PC cooling even now. You still need the same radiator capacity, the peltier just moves the heat away faster and can get below ambient temps at the CPU.

Bit-tech.net was a good one

My parent's new fridge has the word AI printed on at least 5 of the stickers that were plastered all over the thing.
And I bet those stickers ripped when trying to remove them, and left a sticky residue on the surface.

While Peltier cooling have low efficiency wouldn't it be ideal in some cases like: - energy source is solar, DC already and abundant. - cold climate so the fridge can contribute to heating the room Anyway good to know those small electric cooler with Peltier effect must be consuming a lot electricity.
A common use case: coolers. You don't want a whole compressor, but you do want to keep your hot dogs safe and your beer drinkable. It's not very efficient but it's enough for short periods.
There are mini-compressor based coolers available now if you look for them. They cost a little bit more, and obviously have more weight than a peltier, but I think are worth it if a bag of ice isn't viable by itself because they will run for way longer than a peltier setup.

"AI" has become the seasoning you sprinkle on anything to make it sound futuristic
I wonder if there's a site that keeps track of these. It was crypto before, then ML, for a while a lot of job openings seasoned their text with IoT, etc.

#200I wish they had gone into detail about what makes this device different from Peltier coolers that are available today. You can already get mini fridges that use them, but they're not very good - the total amount of cooling you can get from them is not enough to maintain the temperatures that a regular refrigerator does.
Yeah I have a cooler box with a peltier cooler, but it will only cool a few degrees, not sure I'd trust it as a standalone fridge. Plus its energy use is much higher.
