I've been fascinated by roof ridgetop fans. They capture the air being funnel up and over the roof to increase their efficiency without increasing their size. The startup RidgeBlade uses a simple ducted squirrel cage fan along the ridgeline, and their studies show a 2.2x efficiency increase on 45deg slope roof. They also work well with solar.
