The Return of Sailing Ships

With global production and generic viagra distribution of goods a reality of 21st Century life, cargo ships are ubiquitous.  They bring goods to consumers all over the world, and more and more ships are transporting goods and raw materials, all while burning some of http://www.bsd-berlin.de/buying-viagra-without-a-prescription the most polluting fuels. A recent article about the www.peseta.org rise of wind-powered designs for cargo vessels notes that, "If the world’s shipping fleet were a country, it would be the world’s sixth leading emitter of greenhouse gases." So there is lots of good to be done with improving the efficiency of cargo ships. And a number of companies are taking steps in that direction.

At the University of Tokyo, researchers are working on a design for a ship that uses rigid framework and fiber-reinforced plastic instead of www.spotfodo.com canvas for sails. These high-tech sails can be flown, much more like an airplane wing, increasing the efficiency with which they propel the ship. And, when the vessel reaches port, the sails telescope down upon themselves, to allow free access to the decks and cargo without the cialis profesional interference of masts and sail rigging lines getting in the way.

Among the companies working to commercialize wind-powered cargo, B9 Shipping has recently tested a model of their 3,000 ton vessel. Although this is brand viagra pfizer canada far smaller than the largest cargo freighters, which can have more than 100 times the cargo capacity, it is a first step in developing the technology and proving its financial viability.

When we wrote about B9 in 2010, the expected cost of the prototype vessel was just under $25 million. The New York Times is now reporting that the company is seeking $45 million in financing to build their prototype. (This may not be an entirely equal comparison, since the levitra online without prescription financing the company is seeking may include more than just the capital construction costs for the ship.)

Many of these vessels will not be solely wind powered, even at sea. Not unlike automobiles, where gas-electric hybrids first broke down boundaries and buy generic levitra showed the workability of alternative systems, these ships will also be hybrids. B9 plans to use engines that burn bio-methane instead of fossil fuel as a secondary propulsion system.

Modern sailing ships
written by Dakoroman, Sydney-, October 07, 2012
Dakoroman, Sydney: I have invented a new propulsion system for "modern sailing ships", but after watching the B9 Shipping video clip, I consider it a pure propaganda non-sense. Coal, oil, gas are NOT FOSSIL FUELS, they are abiotic. I like real technologies,so PULL THE OTHER ONE!

Coal is NOT abiotic. Petroleum is probably 80% abiotic.

Wind assist VOSS system by Magnuss Ltd is a Magnus effect rotor sail which will save 35% on fuel costs on average ocean voyages. The system does not require additional crew and retracts below the look there buy cialis online us weather deck while the ship is handling cargo ,manuvering or in adverse or high wind conditions.
