I find it surprising how very little happens to the overprepared people, and how much happens to the underprepared. At work I built everything over-spec, redundancy left right and center, backup this, backup that. Nothing ever happens. On the other hand Murphy has this ability to know when you aren't prepared and send everything after you.. call it wierd yeah, but it sure seems to work that way. I'd rather be prepared and never need it. If I do.. well, at least it's going to be a lot better than not having anything.
I'm also concerned about keeping cool in the heat, it's always easier to stay warm in the cold. I have an idea, for those of you with a soldering iron, you can obtain 12 volt or 5 volt computer fans, and with an AA battery holder or two build something that'll run on NiMH or alkalines as a personal fan. 5V fans are the best because they run well on 4x1.2V (realistically, fresh NiMH is 1.25-1.3, so it's all good). I believe the fans will tolerate alkaline as well depending on what you buy.
Give each one in the family one as a personal fan, and add some nice fan guards on both ends to save fingers. I'm planning to do this for my next outage, I don't want to sit and sweat. And you all have NiMH too.
