[quote="dragonfly Jafe"]I saw a nifty evaporator (forget the camp - somewhere near 4:00 and c street I think) - it was a pvc drum like structure with black cloth/canvas sewn into a wrap around it. Additional cloth flaps hung from the drum wrap. A small motor slowly turned the pvc/cloth drum (axis parallel to ground) which dipped the cloth and flaps one-by-one into the water, then they got several minutes in the air to dry. Originally it had a circuit to pause briefly as the rag was in the water, but that had failed. A mechanical cog could do this just as well if not better.
It had no water level limits, no spray, was quiet, and could be easily scaled (by making 2 or more) for any size camp. Unfortunately I had no more film by then. I forget how many people were in the camp, but it was a big one. If anyone knows what I am talking about and has a photo, please post it.[/quote]
Jafe, that was where I was camped, Iron Rose. It is based on a modification of design from someone else (Earth Guardians, or AEZ, or someone). I will see if Gerry (who made it) has any pictures.
The PCV was just a lightweight frame. Everything packed into an amazingly small space.
The logic behind the delay in the power circuit was to save power, the drum doesn't need to move constantly. A mechanical cog still requires continuous power?
