It bears an epic name and is the first ferry which will connect Finland and Sweden powered wind power.
Viking Grace it is in fact equipped with a rotor sail and is a large passenger ship that uses wind energy. This could mean that this will soon be possible for freight ships as well.
As had already happened for the electric power ferry (read the article), the boat in question represents a challenge and an important achievement in the field of transport innovation powered by renewable energy sources.
Viking Grace in the meantime, it sets sail to connect two cities in northern Europe: the Finnish Turku to the capital of Sweden, Stockholm and is the first of its kind to integrate its power supply system with the so-called Rotor Sail, or rotor sails that capture energy wind to turn it into electricity.
The wind-powered ferry that uses the Magnus effect.
The principle on which the electric-powered ferry is based is that ofMagnus effect, responsible for the variation of the trajectory of a rotating body in a moving fluid. The boat takes up a concept from the end of the last century and re-adapted in 2014 first in a modern and efficient version of the Flettner rotor in operation on a ship.
Thanks to the technology contained in the device installed on the boat, the Viking Grace is able to automate and detect when the wind is strong enough to guarantee savings, allowing the company that manages it to save over 900 tons of CO2 per year, Viking line, thanks to a significant reduction in the use of fuels.
An achievement for the entire global maritime industry that will be able to count on a significant reduction in costs, as well as promoting the well-being of the marine environment. When the avant-garde manages to develop solutions that help the environment.
