In the 400 years or so leading up to the adoption of heavy steam power in the 19th century, sailing ships ruled the waves. In an effort to cut increasing fuel expenses and decrease emissions, sails are set to as soon as again show their well worth. However unlike the sails proposed by B9 Shipping and the Wind Challenger Project, Japan-based Eco Marine Power (EMP) is establishing sails with a much more contemporary twist. Instead of simply utilizing the power of the wind, EMP's EnergySail can easily be fitted with solar panels to also utilize renewable energy.
The EnergySail is a rigid take on the sail that sits upon a pole and instantly spins to take complete advantage of the wind and help propel the vessel. At the same time, solar panels embedded in the sail harness energy from the sun to offer electrical power to minimize the quantity of fuel used by auxiliary generators. In bad weather condition or when the ship is at anchor, the sails could be decreased and kept.
However, the solar panels could also be used while the ship is in port, with energy kept in battery modules, offering the potential for absolutely emissions-free operation while not at sea. EMP says a modified variation of the EnergySail could additionally be utilized to collect solar energy when lowered in the horizontal position. The company claims the rigid sails have been designed to call for little upkeep and to endure the high winds discovered at sea.
Building on its previous Aquarius Eco Ship idea-- a cargo ship design boasting a collection of 14 inflexible sails-- EMP has recently unveiled a modified variation of the system aimed at vessels like naval frigates, which would make use of four sails, and smaller sized patrol vessels and coast guard ships that might be fitted with simply two. Solitary EnergySails can also be fitted as standalone units on even smaller vessels, such as cable laying vessel or oceanographic ship, while a variation of the EnergySail targeted at even smaller sized ships, such as ferryboats or fishing vessels, is also in development.
EMP estimates that, relying on the number, size, form and setup of the EnergySails, a fossil fuel-powered ship's yearly fuel consumption could possibly be cut by up to 20 percent, while vessels powered by an electrical propulsion system might cut fuel consumption by around 40 percent. In addition to the fuel usage and harmful gas emission benefits, EMP states EnergySails could possibly also allow ships to run even more quietly at reduced speeds in bays and harbors in comparison to typical ships.
Currently checking a control system that will instantly raise, reduced and position each EnergySail based upon the prevailing weather, EMP is intending to begin sea trials in 2013.

That is crazy and such a great idea!! I wonder how you can get some HVAC in St Paul for a ship like that. Would it be the same or would you have to do it different?
