There is a law irrevocably decreed in the intersewers that if someone makes something, people will insult them for not spending more money on something commercially available and vaguely similar. It is also human nature to latch onto bad ideas and defend them vehemently, so there are very mixed camps with these.

Why do you ask? Intellectual curiosity or you want to be cool?
My experience is that I use a whole house fan and only 'need' the air conditioner on the hottest days. The air pulled in by the fan can come across my back from a window, or straight down if I open a ceiling vent. It exhausts straight up into an aluminum mushroom cap. I've upgraded once already and I have a third vent to be installed as part of a solar collector.
The air conditioner is old and beat-up but it still works. I'm eyeing replacements against the day, I see them secondhand for $25-35.
