I want these built in to my shoes.
There are heated boots that use Milwaukee batteries, you can also get jackets. Don't know when they'll get on the Peltier/TEC train though.
1500 Hong Kong bucks = ~200 US dollaridoos.

In Japan they have tight fitting plastic shells with fans that pump air in to jacket and expels through ends of the jacket. 1

I imagine this is much more efficient than resistive heating clothing and allows for cooling but what about the front?

A whole new market of products opening up around "climate crisis", nice.
Dune style Stillsuit is the endgame here I guess :)
Yep, hopefully soon this cooler will come with water recycling capabilities including from perspiration.

Interestingly, this thermal device come with the environment temperature sensor or thermometer something that a USD2K worth smartphone do not include built-in.

Just wondering does it also utilize heat pump technology for its cooling and heating function?

Not fucking up the planet instead is just not as profitable unfortunately.

Consumerist capitalism revolves around making profit from fixing the problems that consumerist capitalism has created in the first place from making profit. Nice.

Do communist countries not pollute or have industry?
How is moving the goalposts with a whataboutism relevant to my point?

Where did I say communism causes no pollution?

What are the goal posts? You suggested capitalism is responsible for messing up the planet. So thus I ask if communist countries also aren’t responsible, or if that’s somehow distinctly capitalist countries only who pollute?

Seems like a logical and reasonable question to me.

Where did I say Communist countries don't have pollution?

(former) Communist countries like the one I was born in are too poor to generate the amount of excessive consumerism and environment damage rich countries do.

For example there was no such thing as plastic packaging. Everything was packaged in paper, glass or steel way before rich countries made that a hipster thing for greenwashing.

All goods, even low quality ones that would be unreliable, from cars to clothing and electronics, were kept going forever through endless repairs instead of being landfilled the moment a capacitor leaked and new ones bought on a yearly basis because Company X just dropped the new Shiny and the warranty expired on the previous widget, decades before the rapirability trend hit the rich countries.

Is China communist? They certainly produce a lot of pollution and plastic. Videos I’ve seen out of North Korea lately also show people using plastic everything.

But let’s put that aside, and assume the whole world was communist and repaired things (ignoring that repair also happened under capitalism). Is there no pollution? Industry? Seems like even if the pollution is less, we still would just end up in the same place eventually.

China is as communist only because it calls itself so, but doesn't follow any of Karl Marx's communist rules anymore since 1978 or so. It's basically a capitalist dictatorship at this point.

North Korea also calls itself the Democratic people's republic of Korea, you think it's democratic?

And China pollutes a lot because it's the West's sweatshop so rich countries are outsourcing there pollution there by consuming all those cheaply goods made in China at the profit of the western corporations.

>Seems like even if the pollution is less, we still would just end up in the same place eventually.

How so? Capitalism demands virtually infinite growth long term along with visible growth on a yearly or quarterly basis.

Your point framed the issue as one of political systems("Consumerist capitalism"), not moving the goalpost at all to say that communism also or perhaps even moreso is responsible for creating pollution.

If I framed the issue by saying that it's all because stupid people can't live in harmony with nature and someone replies with one of the countless examples of other animals ruining their habitats that is not moving the goalpost at all, that is showing that my framing is incorrect.

No I didn't frame it as purely political but in the frame of consumerism.
I and others took it as political because you put capitalism in front of consumerism.

Even if I were to take out the capitalism from your initial statement: "Consumerism revolves around making profit from fixing the problems that consumerism has created in the first place from making profit."

This falls down when you begin to look at what consumerism is, which is buying and using goods to signal status. This practice has existed since the dawn of time when Ogg traded a new ax to Ugg for the shiny rock to impress Ogget.

The industrial revolution, which it looks like is the actual target of your ire just accelerated the ability for more people to obtain the shiny rocks, leading to the loss of value in shiny rocks and thus the demand for more and new types of shiny rocks.

In a sibling comment, you do make it political by comparing Communist countries to Rich countries: "Communist countries like the one I was born in are too poor to generate the amount of excessive consumerism and environment damage rich countries do."

This is also not a good argument unless your view is that by making people richer and allowing them to have access to more things is a bad idea.

Bringing people up from a subsistence level of survival to a modern lifestyle costs energy and resources. Now, we could say that it is bad to bring people up or that we don't want to. That is a moral argument that you can make, I think that you will be hard pressed to find anyone that agrees that human society peaked at any point in the past in terms of lifestyle, comfort or almost any other metric.

Now, could we be more mindful of how we elevate and progress? I do believe that we could.

How is making a pointless point relevant to any productive conversation? There's no political commentary made by this device, yet here you are trying to introduce it for whatever reasons you think you might have. Now, you've been called on it and are acting like a petulant child with your own version of whataboutism.
Where exactly did I act like e petulant child?

Please stop breaking HN rules by making faceless personal accusations against people and call them children just because you disagree with someone's point.

Complaints about capitalism do not amount to praise for communism.
It’s the clear opposite, and the criticism suggests other modes of economic systems do not have this bug.
This is the 5th generation of the device. I don't think it's a response to climate change in any way. Japan and South Korea is obsessed with self image and (sometimes perceived) personal hygiene, so the device doesn't hit me as odd.

Also, it's in line with Low Tech Magazine's "heat people not spaces" stance, so it's not bad from any perspectives.

Makes sense that this is coming out of Hong Kong. I visited there in late July a few years back and it was unbelievably hot and humid (and I lived in Louisiana at the time).
Go to Tokyo in Summer, you'll know why this device sells.
Anyone else with hyperhidrosis having thoughts about buying one?

Never seen one of these before, and I'm sure people would gawk and think it's weird, but after so many years of suffering I don't think I give a shit.

Thoughts, but also concerns. I'd certainly try out a demo, but I think a peltier cooler that size wouldn't make much of a dent when I'm in "hot mode".
It's been amazing to me how much it helps to use a cooling towel around my neck.
The use case that jumps out at me is people that have to wear heavy protective clothing outside in hot weather. Like motorcycle gear.
I tend to be a bit overweight and also always hot, but I'd instantly get one for motorcycle gear.
I wouldn't wear this over my current hot weather motorcycle gear. I rarely ride over 102F/38C so maybe those in hotter conditions will feel differently.

* Putting on motorcycle gear already takes a significant amount of time, I am always looking for ways to spend less time putting on gear not more time.

* While on a motorcycle you have excellent access to wind, and good summer gear will use that to its full advantage.

* This doesn't cover the parts of the body that gain the most heat in the summer. The head inside the helmet and the knees near the engine are the hottest locations.

* I have bad luck using items not designed for motorcycle riding while riding a motorcycle. Even items designed for riding a motorcycle such as boots can show significant wear quickly. It's a special use case with high forces.

Does anyone remember the "Personal Cooling System" sold in the Sharper Image catalogue in the late 90s / early 00s?
Wonder how these compare to other cooling neck metals. They cost around 3-4k hk for the good style.

Sony went for a different route, instead of side neck cooling, they did the back.

I would love to find one of these that does the opposite -- provides heating instead of cooling.

...also known as... clothes, I guess?

This one does heating.
There's actually quite a collection of heated clothing, which is much easier to make. Milwaukee, Dewalt (and probably all the big power tool makers) make heated jackets and vests.
Insulation plus the power of endothermy can do a lot.
yeah. the worst thing about moving from Boston to California wasn't the first winter, but the second one, where my body had forgotten how to deal with mild cold.
This does both heating and cooling.
I am genuinely curious about how effective these are. If I'm sweating all over my body, will putting this on my upper back help the rest of the body to cool down? Sony must have done their research so what is the principal behind this approach?
The principle is dead simple. Blood circulates through body.
The back of the neck and the wrists are the points where you get a bigger cool down effect if you put them under a cold water stream in summer. I think every runner or cyclist know that. A good amount of blood circulates close to the skin there so it's easy to cool. Blood circulation does the rest of the job.
I bought one of these in 2018 on ebay for my dad, and had it shipped from japan.

Living in the US I had to jump through the hoop of making a fake japanese icloud account just to be able to access the app on the app store, which is how you control the device.

Ultimately it seemed like a really cool device but at least at the time wasn't very effective or practical for cooling down, at least in my and his experience. This was mostly just being outside, doing yard work etc in the hot summer.

I think buying one of the <$50 portable neck coolers on amazon are probably just as if not more effective

Or, for about twenty quid, you can get a semiconductor cooler https://shkspr.mobi/blog/2021/07/gadget-review-usb-c-powered...

I have one. Rather effective at chilling my blood. No app needed.

No battery, so I assume it is rather power hungry? The Sony solution seems much more appropriate for walking around freely (and no noise).

Neither solution really captivates me, even though I am currently in Asia with a heatwave. But then again I do not wear suits nor have professional meetings in person.

Maybe missed it but broken aliexpress link and no name?
handy device to tuck under the ‘nads

I'd really love something like this. I really suffer if I get too hot, but I just can't imagine these being effective enough to make a difference. Maybe the fact that you can feel something coldish on your skin is good placebo though.
I wonder if this is too small to be worth fitting a compressor into, or if the gains over a peltier aren't enough to consider it.

Regardless, I look forward to this or another device like it appearing on the techmoan channel in the coming months.
