Hi Chris, I've forgotten exactly; it was an appendix to a OTEC feasibility study done at least two decades ago. Sorry for the inexactitude. I believe that there's a 100 kW OTEC operated experimentally on Hawai'i; the outflow of which nourishes a few aquaculture operations, including a spirulina

Brian, Where does the “value of this fertility to mariculture is sixty-fold the value of the OTEC power produced” come from? The deep oceanic waters also contain high levels of dissolved organic carbon that need to be taken into account in calculating the overall benefit of CO2 being

Since hurricanes tap energy differences, reducing energy differences weakens them. Ocean Thermal Energy Conversion(OTEC) plants/machines use the difference between cold, near-freezing ocean bottom waters, which underlie the world's oceans around the globe a kilometer or so beneath the ocean

Slowing down winds by stirring the ocean would be equivalent to increasing surface roughness in a model. This would be fairly easy to test, I think. I'm not sure whether the below idea has been suggested before, but using membrane polymers for DAC means that these materials could be adapted to
