I'm also thinking about installing a solar-powered attic vent fan.

I saw one at an energy fair a couple of years ago, and it really seemed to move the air. Makes sense too that the heat from the sun ends up cooling your attic.

We just went through a big heat wave, so the main thing I am looking at is cycling more air through the attic, to keep it cooler, to run the air-conditioning less.

Anyone else have more direct experience with this?

I was also thinking that maybe I could put my wireless indoor/outdoor transmitting thermostat in my attic to get some temperature info for before and after.
