Mesh Tests

With just over a week till we head off to Peru, we thought we'd update you on our experiments so far. Pictured above is our first go at building a 'Standard Fog Collector' just before we put it inside the fog room. It's built out of aluminium square hollow sections, half a pvc pipe for the trough and mesh (from Reverse Garbage) stretched over a clothesline cable. The nuts are attached with fishing line to provide some drop-points for the water droplets.

We're trying to determine the best mesh for the job, so we've sewn different meshes to coat-hanger frames (pictured above) and hung inside the fog room to see which is most efficient (ie best at catching and dripping water droplets). Once we've determined the best one, we'll take the sample to Lima and try and use equivalent locally available mesh. 

Each sample has a 500 mL beaker underneath it, plus a control beaker just in front of it to see how much water is collected just by being in the fog room. We've also got a control PVC trough to compare with the one on the SFC.
