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

Perhaps it will help to emphasize the scale of the OIF opportunity. It takes energy to fix air's carbon, and sunlight is a most sustainable energy source. Much earth-incident sunlight is already used by life on earth, but desert areas as well as High Nutrient - Low Chlorophyll ocean (HNLC)
