   Sure. Isn't that what ceiling fans basically do?

   How do you intend to move the heated air into and through ducts?

   I have thought of using this idea within the cathedraled living room. Instead of moving the hot air down through ducts I thought of moving the cold air, low in the room, up to the ceiling.

   I thought of moving the cold air, low in the room, up to the ceiling.

   Would the cold air then not fall and create a cold down-draft in the room.

   Would it not be better to pump the warm air to the floor level then release it, therby creating a warm up-draft?

   I would rather keep the turbulence up high than down below where there is more dust to get stirred up.I think the cold and hot would mix well enough so that one would not feel the extreems as they would if the hot air was released low.I guess it also depends on the air velocity and direction when exiting the duct. My thinking is to have the cold air released from the gable ends. This would give it opportunity to mix well with the hotter air.Just some thoughts.FrankieThere he goes—one of God's own prototypes—a high powered mutant of some kind never even considered for mass production.
