Windtrap
A device which precipitates water from the air for use by people. (Read the full article)
| "Windtraps for water production have been used here on Earth for thousands of years. They are pyramid shaped strutures made out of loose stones so that the wind can blow through them. They work best in desert areas where the difference between day and night temperatures is 30 degrees or more. Moisture in the air condenses on the stones as they are cooled at night like the condensation on a glass of cold water. It drips down and collects in a catchbasin. These devices worked even when the humidity was very low. Ain't technology great?" (BrotherDog 11/4/2004 8:30:48 PM ) |
| "Just to add a little to BrotherDog's comments, windtraps have been used for thousands of years in Iranian architecture, particularly in the city of Yazd. They're called badgirs (or badghirs), and are really a combination of air conditioners and refrigerators. I don't think they generate more water than they lose, but nevertheless I think they're what Herbert based the idea on; a lot of his Fremen ideas are based on the Middle East (since the Fremen are supposed to be the descendants of current Sunni). There are some good photos online if you want to see what I mean, just google "badgirs"..." (Anthony 11/5/2004 4:17:12 AM ) |
