I also had the same idea, but I wondered if I could run tubing behind the cells,
encased in plastic. Kind of like a watercooled heat sink, I have a couple extra
cells, and could even use them to power a small pump to move liquid around. I
dont want to over complicate things, but would like the best performance out of
this thing. Since I am still waiting for my plastic resin to show up, I can
still add tubing If its a good idea. I posted my progress
here if anyone wants to follow.
