Cargo ship with metal sails would save 30 percent fuel
University of Tokyo)
Can wind energy really power modern cargo ships? We’ve seen the idea of hybrid freighters before, but this concept from the University of Tokyo has a remarkable sail system.
A model of the UT Wind Challenger was recently shown off at the Sea Japan trade show in Tokyo. It would have giant telescoping sails that rise above the deck when wind conditions are good.
As seen in the vid below, University of Tokyo professor Kiyoshi Uzawa and collaborators believe this hybrid system could cut fuel consumption by cargo ships by about 30 percent.
- Yacht powered by wind even with sails lowered
- Navy charters kite-powered cargo ship to deliver equipment
- Sail-powered cargo ship test results in: It cut fuel by 20 percent
The rigid sails would be 164 feet tall and 65 feet wide, made of aluminum and fiber-reinforced plastic. Consisting of five … [Read more]
