Would love to have something like this in some kind of portable vest. So long as the cooling unit and battery pack are reasonably small, I could wear it anytime I leave my house (it's 35+C here in Tokyo and uncomfortable)

  Thank yiu. I'm aware of that option. They last 30-60 minutes before needing to swap out the cooling packs. So useful only when you are near a refilling station.

Leave it to the Japanese to be genuinely interested in high-maintenance convenience gadgets. And yes I've been to Japan in the middle of summer. 35C isn't your problem, it's the near 100% humidity that makes people uncomfortable.

  Then again, "I'm too hot" can be solved on an individual level, even if the solution is bulky (thermoregulating vests are a real thing). "It is too humid" is not a problem you can even start solving other indoor climate control and never going outside.

    I've solved the humidity problem: get comfortable with being sweaty. High heat on the other hand, especially in combination with humidity, would have serious effects. Where I'm from, it occasionally will get to 110F, and rarely 115F, sometimes higher (albeit, with low humidity). I've seen recycling bins melted to the sidewalk on the hottest days. How much water do you (reader) drink in a given day? I wonder how drastic the effects of heat and sweat vary, depending on how much water a person has.

Not necessarily ready-made, but an interesting discussion with Adam Savage about cooling down costumes (including a cooling vest/suit): https://www.youtube.com/watch?v=-oQUn8fTxa8 https://www.youtube.com/watch?v=-oQUn8fTxa8

I keep wishing to make a solar powered peltier cooling module vest..
- rm_-rf_slash 8y ago
  Peltier cooling modules are pretty cheap nowadays, but they require too much power and need too much heat sinking to be useful in a wearable, in my opinion. Either you become a walking solar panel or you have to carry around a pretty hefty battery for it to be useful for any significant period of time, and either option may end up weighing so much that you’ll heat up anyway from carrying all that extra weight around. As much as I would love to have a peltier cooling vest, I don’t think it’s practical. However, if there existed a muscular exoskeleton (in the vein of power armor from Fallout or The Expanse) that could compensate for its own extra weight and bulkiness, then an active-cooling garment might actually work. Or just buy an air-conditioned fursuit ;)

    maybe circulating exo-skeleton ? with cooling gloves and soles
    - rm_-rf_slash 8y ago
      That would be pretty awesome, although I can’t imagine it would be anything more than a garage project without some way to significantly reduce the weight or have it handle some of the weight through some sort of active posture control. But if those things can be resolved, I bet there are some juicy defense contracts waiting in the wings...

  huh, never seen those used anywhere outside of motorsports.

Start with athletic wear. There’s a lot you can do just to avoid getting sweaty and it really does help. For me shirts and socks make a big difference.
