We can learn so much from this….a good and interesting read. Janet
Wind towers – aren’t they just beautiful? Not only that, they provide low-tech, totally renewable energy solutions to day-time desert heat waves. Within the capped tower is a port that is opened towards the prevailing wind. Some towers are multi-directional, the vents opened and closed as appropriate. Air is drawn into the living quarters below, its movement providing the cooling effect.
When there is no wind, the tower acts as a chimney, venting hot air from the interior. A more sophisticated version involves an underground canal, qanat, in which case the wind tower vent is opened away from the prevailing wind, and the system pulls cooling air up from the canal. You can read more about this if you follow the link.
But it seems to me to be an example of perfect human ingenuity – problem solving with minimal impact on the natural environment, while at the same…
