Solar raft
Thought: Solar rafts floating on oceans near equatorial regions, more efficient than OTEC and wouldn't tak up land area. Sea conditions there are generally benign. Rafts in grid could be spread out a bit to let in light underneath. Underneath they would also create a floating habitat as happens naturally with large floating objects in the ocean. This provides an anchor for plants which allows fish to hide in an otherwise open ocean. It could perhaps be an automated site for liquifying hydrogen that could be split from seawater, aiding the hydrogen economy. This could be shipped or piped around the world.
