- tomohawk 12y agoI can see how something like that would work in arid conditions, but in areas where it is humid, it seems like you would get a lot of problems with mold and dampness.
- kijin 12y agoNone of the A/C alternatives I've seen on HN in the last couple of years even try to tackle the problem of humidity. They only focus on lowering the temperature, and sometimes even increase the humidity while doing so. Maybe this has something to do with the fact that a lot of U.S. tech startups are located in relatively arid parts of the country, such as the Bay Area. I'd like to see what they can come up with if they were all relocated to Florida, or even better, Southern China.
