It looks like it's more of an air "cooler" than an air conditioner. It probably works somewhat depending on the climate, but air conditioning actively cools the air (it produces colder air than the exterior air temperature) and reduces humidity.

Yeah so as I expected. It would work well in a lot of climates today, but it's basically just a very well directed fan. If the wet-bulb temperature is high, it's not going to help.
