Cloud of Sea is an innovative user-friendly tool, adaptable to any type of boat, which encourages and facilitates seafarers interested in the health of the marine world, to remove microplastics that contaminate the waters of our planet. Cloud of Sea is a product designed to be hooked on to all boats using ropes. The product contains an internal rotating filter that can capture micro-plastics in the water. Cloud of Sea moves in the sea via a boat so therefore it does not need any other source of energy to move through the sea to collect micro-plastics. It is an intuitive product and allows for easy carryover and sorting of rubbish on the shore. This product can be sold to port areas, where sailors rent it and in return receive discounts within the port, promoting a new type of system for the protection of the sea.
