Vindskip (or Windship) is a Norwegian concept ship designed by Lade AS. This hybrid is partly wind-powered, using a specially-shaped hull to harness the power of the wind. The designers claim that their prototype, while not 100% wind-powered, will reduce emissions by 80% and achieve fuel savings of 60%.
The idea was inspired by the aerospace industry, and they created a hull which they describe as a symmetrical airfoil. The airfoil helps harnesses a force akin to aerodynamic lift, pulling the ship along. The symmetrical airfoil ensures that “lift” is generated when the wind comes from both port and starboard sides. The company manager says that “You can compare a symmetrical airfoil with a ‘normal’ sail.”
The company suggests that a computer navigation system could pull in weather data to plot an optimal course. The ship would use a liquefied natural gas-powered electrical generator for the remainder of its energy requirements and to get going from a standstill.
