Mitsubishi Successfully Tests World's First Cargo Ship with Foldable Sail-Wings
Mitsubishi has completed the trials of the world's first cargo ship with foldable sail-wings - and it has exceeded all expectations. Over the course of six months of testing, it crossed the Indian and Pacific Oceans, as well as the North and South Atlantic. Initially, it was estimated that the sails, which are as tall as a 10-story building, would save 1.5 tons of fuel per day, but in practice, the savings amounted to at least three tons. Now, these sails are planned to be installed on other cargo ships - three sails per ship - which will further reduce fuel consumption.
