Kite-powered ship sets sail. Answered
German container ship MS Beluga SkySails has set sail for Venezuela from Germany, towed in part by 160 square metres of parafoil.
The kite is flown at an altitude of around 200m (depending on exact wind conditions), and is expected to save nearly $1600 in fuel costs every day.
The kite is computer-controlled, flying in a constant figure-eight to maintain traction.
If this trial is successful, kites of up to 5000m2 are planned for future trips.
