My fans are circulation fans, positioned fairly high up, in the hope that this will also pull cooler air in from outside. as there are paired ridge vents along the length of the roof. Point taken that intake fans could well be rather more effective. Ernie, my reference to scams was a response to you...

Re: Cactus world

Thanks Teg! Interesting article Terry. Some of my colleagues in my research group Cardiff University worked on nonphotorealistic rendering - computer algorithms that take in a photo, and automatically re-render it in an "artistic" style.
