Double pyramid structure for building has outer pyramid with slits to admit visible light and IR and has inner pyramid containing accommodation and has spray producing stream of water down outside

摘要

The double pyramid building structure (1) has slits (11) in the outer pyramid (2) to admit visible light and IR (5). The pyramid is a regular four-sided pyramid. The inner pyramid (3) is similar in shape to the outer pyramid and contains accommodation and has windows (15). A spray head (7) on top is connected to a feed pipe (6) leading from outside and produces sprays of water (9) running down the outside (12) of an evaporator body (4). Water vapor may condense on the inside surface of the outer pyramid and the condensate runs down into a water trough (10). Access to the inner pyramid is via an underground tunnel (14).
