Default chimney!! thats where im at

thats actualy the basis of my idea!! the plan that im am tossing around is a res. made of a double walled cylinder with a small silent fan at the bottom blowing straight up the center. there would be fins or ridges similar to the resorator on the outside and if possible on the iside of the cylinder too. i would like to use large diameter pre-made metal (preferably aluminum) tubing for the res, but i will have to see. some of the metal pipeing i have seen is ridged , which means more surface area!! inside the res i am thinking about running a small coil of copper tubing that will (1)spread the heat evenly around the res. and (2) dump the hot water on the opposite side of the cylinder than the pump so that im not recirculating the same hot water i just put back in. i know the addition of a fan is not passive cooling, but it might need to be there in case i get busy!!

i now have a rough draft (really rough) that shows the basics. not shown are the water fill and several small details.
