Shell Structure

Here's a nice water bottle structure by Shigeru Ban. Our final structure need not resemble it, but it's a nice reference to start off from.

I've sketched a shell structure in which how the collection, filtration and storage can be organized in it. It might be a simple but sound structure to hold the fog collection nets as well as for water drainage to filters and storage tanks at the bottom.

The weak point might be on the top of the shell, thus rigid joints between bottles should be introduced.

For structures that depend on others eg trees, this is an interesting way to tie the bottles together Plastic Bottle Chandeliers
