Wave Power Ship
A wave-powered ship is a ship, propelled harnessing the energy of the waves. Ships Constructed boats As yet, there is only one boat that is propelled by wave harnessing fins: * Suntory Mermaid II ''Suntory Mermaid II'' is a 9.5-metre, 3-tonne catamaran driven by wave power. It features two fin tails which absorb wave energy and generate thrust by moving up and down with the motion of the boat. The ship was designed by Hiroshi Terao of Tokai ... : ''Mermaid II'' uses a passive fin mechanism mounted at the bow. A combination of fins and springs capture wave energy, then release it as a propelling drive forwards. Ship concepts 1. Ship concepts having wave harnessing fins like the "Suntory Mermaid, described above: * ''E/S Orcelle'' A conceptual design for a large car ferry has been projected. This is planned to use wave energy as a minor component of its energy supply, the major source of which is hydrogen fuel. 2. Ships with several hulls, that are movable among one another: * ...

Suntory Mermaid II
''Suntory Mermaid II'' is a 9.5-metre, 3-tonne catamaran driven by wave power. It features two fin tails which absorb wave energy and generate thrust by moving up and down with the motion of the boat. The ship was designed by Hiroshi Terao of Tokai University. World record On March 16, 2008, then 69-year-old Japanese sailor and environmentalist Kenichi Horie left the Hawaii Yacht Club, Honolulu, in ''Suntory Mermaid II'', bound for Japan. He arrived on July 4, 2008 in the Kii Channel offshore of Hinomisaki cape, Wakayama, Japan, without incident. Horie had made the world's longest solo voyage in a wave-powered boat, using green technology.afp.google, Japanese sailor first to cross Pacific in wave-powered boat The non-stop voyage across the Western < ...

Hydrogen Fuel
Hydrogen fuel refers to hydrogen which is burned as fuel with oxygen. It is zero-carbon, provided that it is created in a process that does not involve carbon. It can be used in fuel cells or internal combustion engines (see HICEV). Regarding hydrogen vehicles, hydrogen has begun to be used in commercial fuel cell vehicles such as passenger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for spacecraft propulsion and is being proposed for hydrogen-powered aircraft. Production Because pure hydrogen does not occur naturally on Earth in large quantities, it usually requires a primary energy input to be produced on an industrial scale. Hydrogen fuel can be produced from methane or by electrolysis of water. As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming or partial oxidation of methane and coal gasification with only a small quantity by other routes such as biomass gasification or electrolysis of water ...

Ship Types
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were ...
