This tropical cyclone weakening system involves, firstly, injecting cold water drawn from depths of at least 200 meters into the surface of seas and oceans, and secondly, injecting this water beneath a layer of sargassum seaweed to limit the warming of this deep water. This system operates primarily in areas of the North Atlantic where both the major cyclone tracks and sargassum beds are located. The aim is also to capture the sargassum at sea so that it no longer washes ashore. Furthermore, the system allows for continuous electricity production through its ocean thermal energy conversion (OTEC) plants and includes a sargassum collection system to utilize the harvested sargassum.

The useful solution refers to a process for producing instant seasoning from fermented Sargassum quinhonense seaweed. This process involves treating the seaweed with soda, then fermenting it with a mixture of Lactobacillus plantarum, Lactobacillus pentosus, and Lactobacillus farciminis bacteria. The resulting mixture is then combined with spices and dried. This dried fermented Sargassum seaweed product is then mixed with food additives to create an instant seasoning. The instant seasoning produced using this solution has a distinctive flavor and can be used directly with rice as a supplementary food, or sprinkled directly onto rice.
