High sea surface temperatures (SST) are a major factor in the formation and maintenance of tropical cyclones. Global warming has contributed to a rise in SSTs causing an increase in tropical cyclone formation. This increase in SSTs in the Atlantic basin is attributed to failing of the ThemoHaline Currents (THC) that provides warm ocean waters to Europe. Should the THC fail, it is estimated that Europe would be plunged into a 200-400 year ice age. The invention described herein uses OTEC or similar technology to pump cold ocean water to the surface, reducing SSTs limiting the formation and growth of tropical cyclones. Additional benefits would include strengthening of the THC as well as providing a stop-gap solution for global warming while more responsible manufacturing and industrial methods are designed and implemented. With limited additions to the OTEC platform other benefits can be derived including but not limited to mariculture, algaeculture, biodiesel and ethanol production, and carbon sequestration.
