In addition to using vertical axis wind turbines, electrical energy is also collected by solar means. Two applications of solar glazing are used: the first, a semi-transparent solar window is used facing the open-air, inner vortex; the second, a glass with a printed array of solar cells spaced to create partial shading, is used as a solar pergola or roof material. Furthermore, underwater nacelle’s function both as tidal generators when the structure is anchored and as thrusters for propulsion when Gyre is under way. The structure manages undersea pressures and stresses by virtue of its shape. Rainwater is harvested in the inner vortex and gravity fed to the water purification system at the base of the Gyre. Mechanical systems and emergency freshwater storage basins are in the deepest portion of the structure.
