Most rotating floors of a high rise are relegated to the topmost floor, which is usually a restaurant. Not so for David Fisher’s Dynamic Tower. EACH of its 80 floors rotates. It will take up to 3 hours for a floor to make its 360 degree trip. The tower will generate its own power from photovoltaic solar cells and 79 wind turbines, one of which will be located between each floor. The estimated cost for one of these buildings clocks in at about $700 mil. So far two are on order. One for Moscow and one for–no surprise–Dubai.
