Interestingly, this averts the strong issues of evaporation-based air coolers as explained e.g. on [(67) Personal "air conditioners" aren't what they seem - YouTube](https://www.youtube.com/watch?v=2horH-IeurA). TL;DW: this works even if air is pretty humid.
When used outdoors this also even averts the issue of only moving heat very near.
# Predictable minus sides of the T-shirt option
People with extremely short hair and static position indoor might probably notice a heat flux rising to the back of their head, in practice this may not be a problem.
On the contrary, what happens if long hair covers the device? Hair being an insulator, the device may lose a lot of its efficiency.
Also, resting on your back (e.g. napping) wearing this device would lose its efficiency.
Apart from those specific situations, this looks like a cool device!
