Fans - what are they good for?


So in the absence of Charlotte and Rachel sending me tidbits of wisdom, I'm going to write my own - and it's about fans...
Being incredibly hot in our terribly insulated, badly positioned house, and having ONE fan as our cooling method during these hot nights - I've been pondering the idea that fans might actually not be all they are cracked up to be....
Do fans just push the hot air around so it feels like it's cooler, or is there some method behind their apparent hard work? I'm beginning to think that they actually just massage our mental state, allowing us to THINK that we are being cooled down...
Anyone else got a theory?

  1. I'll happily explain the physics of this to you in detail (and why opening your firdge door will not cool the kitchen) but suffice to say that fans do work (just like wind chill on a cold day makes it feel colder than the ambient temperature) - However I think you need more air moving around - unfortunately on a hot day the cooling effect of one fan is probably less than the heat produced by its motor so you are actually warming your house up!
