Salesforce Transit Center's structural fiasco saga revisited


The cracks discovered beneath the rooftop park were classic brittle fractures. The tapered 4-inch-thick steel beams—2.5 feet wide and 60 feet long, with a horizontal flange on the bottom—undergirded the 5.4-acre park on the building’s fourth level, and buttressed the roof of the bus deck on the second level. By themselves, the cracks formed a point of weakness with potentially hazardous consequences. But they also suggested the possibility of a larger crisis.

Going beyond borders, oceans, and thinking of the continents as a continuous entity comes from this vision. Fifty years later, we face the existential threat of ecological disaster, and maybe revisiting the whole earth project seems like a way of recapturing that drive. This proposal looks at a network of towers that span across the oceans connecting the planet in a matrix that provides energy cleans the oceans and gives new chances for life to thrive. Fusion, Solar, and Hydro-power are used in this matrix with all of these being in high abundance in the ocean.
