Here is a complete, self-contained 3D WebGL scene built using modern Three.js. I have designed it to exactly match your specifications: the dimensions, the 45-degree dished legs half-submerged, the tension cables, the fold-down solar canopy, and the banana propellers positioned 5 feet behind the mid-underwater section. 1 Unit in the 3D space is equal to 1 Foot. Save the code below into an `.html` file (e.g., `seastead.html`) and open it in any modern web browser to view, rotate, and zoom the interactive 3D model. ```html Seastead 3D Concept
