Mechanical design of the Ocean Grazer's floater blanket

Nowadays, global warming is in the order of the day, as the majority of the countries are experiencing heat waves and other insalubrious atmospheric phenomena continuously. Some countries in Europe, such as United Kingdom, have recently broken historic high temperature records in winter months, wher...
