Show HN: Mini-Air Personal Air Conditioner
- GFischer 12y agoNo idea how it works, but I really hope you can make it happen. There's a HUGE market for this kind of thing in the 3rd world, especially for those who can't afford air conditioners everywhere, or where electricity is spotty (including some of the biggest cities in the planet).
- HeyLaughingBoy 12y agoHmmm. 3" tall, about 1.5" in diameter. Cooling air by around 10 degF. I'm not going to be so uncharitable as to say "impossible," but I will note that it would require the energy density of a bomb even if the entire volume were nothing more than batteries. Not something I'd wear around my neck! I wonder where the hot air goes...
