Abstract
Abstract Apparatus for collecting fog water consists of a slotted stainless steel rotatable tube. The tube is rotated and fog droplets are collected by impaction on the tube. Centrifugal force causes the water to flow outward toward the ends of the tube where it is collected in small vials.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
89 words
A fog water collector comprising: at least one hollow elongated tube having a slotted opening formed along a substantial portion of the length of said tube; means for rotating said tube in a direction such that said fog water passes through said slotted opening and impacts on the back wall of said tube; and removable container means for each said tube, said container means receiving tHe fog water impacted on said tube as it moves to the ends of said tube under the influence of the centrifugal rotational force.
Claim 2
Dependent Claim
89 words
A fog water collector comprising: at least one hollow elongated tube having a slotted opening formed along a substantial portion of the length of said tube; means for rotating said tube in a direction such that said fog water passes through said slotted opening and impacts on the back wall of said tube; and removable container means for each said tube, said container means receiving tHe fog water impacted on said tube as it moves to the ends of said tube under the influence of the centrifugal rotational force.
Claim 3
Dependent Claim
15 words
The fog water collector of claim 1, wherein said tube is formed of stainless steel.
Claim 4
Dependent Claim
24 words
The fog water collector of claim 1, wherein said container means is a polypropylene vial which is threaded onto the end of said tube.
Claim 5
Dependent Claim
25 words

Claim 7
Dependent Claim
97 words
A fog water collector comprising: at least one hollow elongated tube having a slotted opening formed along a substantial portion of the length of said tube; means for rotating said tube, said slotted opening facing in the direction of rotation so that said fog water passes through said opening and impacts on the back wall of said tube; and at least one removable container means for each said tube, said container means receiving the fog water impacted on said tube as it moves to the ends of said tube under the influence of the centrifugal rotational force.
Claim 8
Dependent Claim
97 words
A fog water collector comprising: at least one hollow elongated tube having a slotted opening formed along a substantial portion of the length of said tube; means for rotating said tube, said slotted opening facing in the direction of rotation so that said fog water passes through said opening and impacts on the back wall of said tube; and at least one removable container means for each said tube, said container means receiving the fog water impacted on said tube as it moves to the ends of said tube under the influence of the centrifugal rotational force.
