To solve the problem of a present state wherein not wholly adopting a global warming preventive measure, except for only prohibiting marine abandonment in ratification of an international treaty for preventing marine pollution, though the global warming preventive measure can be performed in a special environment of a ship, when viewing a limit of the global warming preventive measure of the industrial world, in a conference in various places in the world for preventing global warming.

Power generation using natural energy is put in an environment to be most effectively used, and at the same time, the whole operation energy of a ship-mounted apparatus breaks down a disposable present state, and generator driving energy wholly matches for free no-energy in photovoltaic power generation, wind power generation, power generation using operation energy of a mounted apparatus, power generation using fluid energy in a pipe, and at the same time, power generation using flowing water energy outside of the ship by a sailing speed. In a process of evolving a main machine up to electric propulsion from an internal combustion engine, a hybrid ship is also possible, and is put in a transition period for coping with an environment of the shipping world in the future.
