Have you been to Singapore? Plenty of people don't use AC, unless you
are talking about office towers and shopping malls. Visit some
residential areas sometime, you'll see curtains flapping in the wind.
You'll also see thousands upon thousands eating at open-air restaurants.

I live a few hours up the road from Singapore, and I sure don't use it.
With a cross-breeze and a fan it's perfectly nice in here. According to
my trusty thermometer it's currently 81F/27C indoors, at 2pm (hottest
part of the day, and it hasn't even rained yet to cool things off).
Marble floors, a thick, insulating roof, and windows on two sides make a
big difference.

When I go to people's houses I would say about 1 in 5 have the AC on
(usually foreigners), despite the fact that almost all of them could
easily afford it.

Again with the moving targets.

You claimed that a fan was useless for feeling cooler because any space
would become increasingly humid until reaching 100%. Mrtravel points out
that few people sit with their fans in sealed containers; they open a
window.

So no, not more hot air - more air that's the same temperature. The
important thing about the new air in this discussion is that it's less
humid than the air which has supposedly been rapidly saturated by your
profuse sweating, allowing you to continue to cool down by perspiring.

so windows haven't been invented in France, funny they have the
words "ouvre la fenetre" (or something similar).
