In one embodiment, this invention pertains to desalination of seawater by eding methane into seawater at a depth generally exceeding 100 meters to form methane hydrate which rises to where it is decomposed into methane and water, and recoverig water. Methane is recycled to depth to form more buoyant hydrate.

Em uma incorporação, esta invenção pertence ao desalination do seawater eding o methane no seawater em uma profundidade que excede geralmente 100 medidores ao hydrate do methane do formulário que se levanta a onde decomposed no methane e na água, e água do recoverig. O methane recycled à profundidade para dar forma a um hydrate mais flutuante.
