Japan's largest shipping company Nippon Yusen KK and Nippon Oil Corporation to develop a solar cell systems, can carry 60,000 tons of the Toyota-powered vessel 40 kilowatts. Toyota in 2010 with the introduction of new environment-friendly Prius car roof to install the solar panels, installed on the board of these solar panels, the main vessel for the engine.

Solar panels used in ocean-going ships is not new, but so far, the only solar cells for cabin crew members and can live for the cabin. The new solar system will save 6.5 percent of diesel consumption, and reduce by 1% to 2% of carbon dioxide emissions.

These figures do not sound, however, the plot is not difficult to step into a brief journey of a thousand miles, the number of particle pollution, any reduction will help a little bit,

Save a lot of fuel

The average cost of a cargo ship sailing to 1 gallon of fuel, 0.008. About conversion to the speed of each ship was sailing in a fuel consumption of 120 gallons of fuel cabins.

This shows that, starting from Japan carrying a cargo of 6,000 new Prius, across the Pacific arrived in the United States must consume at least 720,000 gallons of fuel. However, the new solar cells from the same navigation system, will consume 46,800 gallons of fuel.

It is important that regardless of how much energy can be saved, any shipping pollution reduction is a good thing.

U.S. "Environmental Science and Technology" The results show that the world every year, about 60,000 people, as a result of pollution resulting from shipping to death. Pollution of coastal cities in the micro-particles of about 44% of the sulfate emissions from shipping.

The development of clean shipping

Based on the above data, California, approved by the regulatory authorities in the United States ocean-going vessels of the most stringent emission reduction requirements. From the beginning of July 2009, the ship into the harbor of California, to be away from the coast in waters 24 years, the use of cleaner fuels. These provisions will be implemented in 2015 with international standards similar.

The development of clean shipping is a good thing, of course, the world's inventors are also working hard to carry out this cause. Headquarters in Hamburg, Germany, the days of sail, the first to rely on the R & D installed on board the giant cargo ship flying the pull of "Moby Dick fan days", sailing (depending on weather conditions and wind) saved more than 20% of fuel consumption. In Scandinavia, Sweden shipbuilding giant round of the China Shipbuilding Wilson, a research and design is depend on solar energy, wind energy and fuel cells can for the ship.

Nippon Yusen Co., Ltd. company spent 140 million dollars to develop its solar panel system. With the first batch of the ship's solar panels are expected to be available in December. The new Japanese oil company executive vice president, said he hoped that the solar system in 3-5 years to achieve commercialization.
