Operations
Fill up the bucket of water. You will need to fill the refrigerator backing. This is the rough part. Use gravity to help you out but you will need to suck the water through the cold-in side. Go ahead and attach the nylon tubing to the refrigerator backing that you are going to suck through helps to make this step more enjoyable.

Take the temperature of the water before you set the system in the sun facing south. Each hour, check on the system and record difference in temperatures of the water and ambient air.

Hey, can you drink this water? I've just finished making a similar on to this with a freon-removed fridge condenser, and it heats water like a charm, but at first the water came out oily. Now it's coming out cleaner but a bit brownish, like maybe the pipes are corroding. I'd like to use this to make coffee but I don't want to kill anyone. Anyone have ideas on cleaning/testing for chemical content? Thanks!
