Evaporative vs Refrigeration cooling

Once upon a time I lived in the Mojave desert.  It's the most arid place that I've ever been to, although from what I've seen, it's nowhere near as dry as the Sahara desert.  In the summer months, the sun is intense and the heat is brutal.  Any time you live in a desert, it's a great idea to try to keep the inside of your house from getting as hot as the rest of the desert!

Garage door alarm

I'm taking a brief break from Hydro failures and the depressing loss of life that goes along with it.  I have a post on the Johnstown flood in draft, and will get to that shortly.

Meanwhile, I thought I'd put up a post about a practical home improvement.  I thought of the idea after reading this article.
