I have a friend who built about a 12x12x10 foot shed from rough cedar 10 inch thick walls filled with saw dust. It sat on an insulated concrete floor with copper lines on it. In the coldest part of the Wisconsin winter he'd start running water in the shed an inch or two at time and of course it would freeze. By the end of winter he had a block of ice the size of his shed, he'd seal it up tight and when the heat showed up he would circulate water through the copper pipe and through a radiator in his duct work. It was cold enough to condense and get the humidity out of his house. Last I knew he was working out a few kinks in the rig. I've lost touch with him but might have to look him up to see how it worked out. I've always wondered how long his ice lasted. Around here we've got snow piles that make it into May out in the sun.
