Designer Phil Pauley has a dream: he wants to build a new biosphere, but instead of putting it on solid ground, he wants to put it in the middle of the ocean. He envisions a scientific utopia, one that could work either floating on the surface or down in the watery depths.
His design consists of eight living biomes surrounding one larger, central biome full of control equipment. The smaller biomes would be where people would live and experiments would take place. And through an "innovative control of variant atmospheric pressures that occur at depth," the entire thing would be self-sustainable, generating its own electricity and other resources.
It sounds neat, to be sure, but who would lay out the cash for such a pricey endeavor?
