SANDAEROCITY

Sandaerocity, Aero-City, Acity, is a modular cube-sphere composite buoyant atmospheric aero city, solar-wind energy, photo-electrolysis of water vapor storing buoyant energy as hydrogen/oxygen, fuel cell reconverted to water plus energy, high/low atmosphere temperature/composition control/circulation, can reduce Earth/Venus temperature, laser convert hot CO2 into C (Carbon Graphene used for buoyancy envelopes) and refrigerated O2. Acity is the aero component of Global Green Gcities, in addition to Ocities (Oceanic), Tcities (terrestrial), Ucities (Underground-water) and Scities (Space Cities). Sandaerospace/Sandaerotower can be combined or expanded with addition of Sandaeroblocks/Sandaeronets modules into a Sandaerocity that can also be combined with a Sandaerovator, a aerospace pyramid-tower elevator-accelerator.
