May I offer a related not-engineering comment. I have explored the financial feasibility of seasteads. I am comfortable sharing my findings. I expect you all are able to define the physical feasibility — or not. I encourage you to share your thought about cost for such a platform. I can articulate the “value.” As I guide only let me offer that the platform cost can not exceed 20% of the total occupied use.
This is an approximation only but please accept this for this moment. A single level of building occupancy might be thought to be 150 pounds / square foot. So the displacement must be grater than this. What volume of biorock is required for this? What si the cost for this displacement? Can we go to 2 levels of human occupancy? Can we go to 3 or 4 or 5? At what cost?
I am offering to do the pro-forma financial analysis if you all can join to provide the cost / square foot of platform cost and displacement. I know that my economics are odd on an engineering thread — Financial feasibility is part of a simultaneous equation ---- engineer is another. My credentials can be found at www.amentaco.com ---- Ted
