A solar energy powerplant is described comprising a group of seven or more vertical towers open at both ends, these towers being mounted on a base structure in an equally spaced configuration with a single central tower surrounded by at least six towers. A plurality of vertically spaced, radially projecting heating chambers are mounted externally on each tower, each chamber projecting from the tower a distance at least equal to the radius of the adjacent tower. The chamber at each level is divided into a series of segment-shaped compartments separated by radial divider walls, each segment-shaped compartment having an inlet for ambient air and an outlet into the tower for heated air. Secondary heating chambers are associated with the radially projecting chambers, with each secondary heating chamber being positioned beneath a radially projecting chamber and having a V-shaped configuration with one wall thereof being a wall of the tower and the other wall thereof being upwardly and outwardly inclined from the tower wall and connecting at the upper end thereof to a bottom wall of the radially projecting chamber to thereby form both a secondary chamber wall and a support for the radially projecting chamber. Each secondary heating chamber has an inlet for ambient air and an outlet into the tower for heated air. A water reservoir is mounted at the top of each tower and a water reservoir is also in the base structure of the powerplant; Conduit and pump means are provided for moving water between the reservoirs by way of heat exchange coils in the heating chambers such that hotter water is stored in the reservoir in the base structure and cooler water is stored in the reservoir at the top of each tower. Tiltable concave mirrors are mounted on the outermost edges of the segment-shaped compartments and wind-powered impellers are horizontally mounted in at least the upper half of each tower in vertically spaced locations in association with the heating chambers, these impellers being adapted to drive electrical generating units.
