Abstract: Self-inflated marine airship or balloon for producing hydrogen by separating it from water, using electrolyze process and electrical power that is produced by wind utilization. The marine is basically comprised of an air unit, i.e. the airship or the balloon, and of a water unit, that is a pod sunk in a water, e.g. lake water or sea water, and having a turbine driven electric generator. The water unit is harnessed to the air unit by cables, and when dragged by wind, the turbine drives the generator to produce electric power which is then being utilized to separate water molecules into oxygen and hydrogen which is in turn directed to the air unit through a pipe connection, for a storage.
