Here's an interesting idea: http://www.foxnews.com/story/0,2933,319473,00.html So now we just need to train it to collect all the snow, drop it in a big hole with heat pipes near the bottom, and then get significantly cheaper air conditioning in the summer. I read somewhere that a typical house would require it's own size in frozen water to cool the house comfortably for a full summer, but I don't recall the details (temperature of ice, duration of summer, etc) - it was a back of the envelope calcuation anyway, but is a handy guide for sizing ice cubes for cooling purposes. Although one has to get rid of the water by the end of summer for new bricks -perhaps pass it through a heat exchanger to extract the 'cool' (heat up) and then water the garden. Alternately use all that warm water to heat the house in the winter. -Adam -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
