Ultra low cost Aqua-solar AeroTrain, with on board electric ducted-propellers, cable/track/block hook/wheel/magnet and/or cold/hot gas rocket propulsion; modular passenger, cargo and buoyancy floating carts (H2+Steam mix, electrolysis of H2O and H2 Fuel Cell) with top solar panel/film; modular pile-up green residential-commercial and wind-solar power at base towers; cable/tube energy, communication and sanitation distribution; vertical AeroTowers/AeroRoofs and horizontal AeroParks stations with gardens and pedestrian/cyclist pathways. Sandaerotrain can use cables, tracks and/or tunnels with different levels of speed and number of stops. 3 level cable-track-tunnel tower-station home-offices. Composite modular independent cabin Ocar cube-sphere can pick-up/drop/join e-track cart (50-100km/h/ 1 km stop), e-cable airship (150-250km/h /10 Km stop) or e-tunnel vacuum-composite-module (500-1000 km/h / 100km stop):
