Sweden has the largest wind powered ship

The transatlantic liner Oceanbird is designed by the Swedish shipbuilder Wallenius Marine, the company also

will finance the government and severalresearch centers. The vessel can accommodate 7 thousand cars. The vehicle, 200 meters long, will look completely different from other sea vessels. Five "wing sails" were introduced into its hull, each of them being 80 m high. They can turn 360 degrees without touching each other, the sails can be removed to pass under a bridge or in order to wait out bad weather.

Sails to be made of steel andcomposite materials, made large enough to generate enough power for a vessel weighing 35,000 tons (when fully loaded). In order to take into account the atmospheric conditions and create a housing, the researchers installed several sensors at an altitude of 200 m above sea level. “All this information helped us design an efficient wing and hull system that can make the most of the wind energy,” the researchers note.

New nanomaterial acts like a molecular thermometer

The authorities of many countries demand reductiongreenhouse gas emissions from the shipping industry. In 2018, shipping accounted for 2.89% of global human-induced greenhouse gas emissions, according to the International Maritime Organization (IMO), the UN body that regulates global shipping. In the same year, the IMO introduced a mandatory 50% reduction in total annual greenhouse gas emissions by 2050.

The new vessel is designed to beeven exceed these numbers - it will emit 90% less carbon than any other marine transport vessel. However, so far scientists cannot completely get rid of harmful emissions - the engines are running in the vehicle, which are needed for maneuvering in ports and during emergencies.
