Propped up on the tower, like the propeller of
a helicopter, is a wind-wheel, a wind turbine.
Down below, inside the courtyard, a ring is
cut into the landscape, separating one circular band of ground from the rest of
the landscape. The separated ring of ground is a turntable, with a built-in
track that fits over a circle of wheels below the ground.
The turbine up on the tower generates
electricity for a set of motors down in the courtyard, under the ring of
landscape: powered by the turbine, the ring of landscape rotates.
