Here's the deal. I'm planning a camping trip with my daughter that will take us to the top of a high ridge for two nights. The ridge has no water at the top but there are several seeps visible with binoculars from an opposite hill where we usually camp.

We will be doing this trip in July, dry/cold season for Brazil so I don't want to depend on these seeps to replenish our water supply. The ridge is always covered in cloud in the morning and I'm betting there is a healthy dew on the ground up there.

I know we could soak up water with sponges but is there a more effective way to harvest water from heavy fog? I know our tent will get covered with hevy dew and will probably yeild a half liter in iteslf. I would like to pack in a days supply of water and harvest enough to stay another day if possible. Mac
