Hi Ken, I had thought of doing it with a drip tank, yes. That definitely seems like the simplest passive setup. I bet we could figure out something else though.
My main goal with a passive setup would be to do away with fan noise. >From that perspective a battery or solar powered pump would probably be a fine addition, because depending on the model of pump it could be quite quiet. I do like the elegance of totally passive systems though. I'll roll it around in the head for a bit.
