Back in December, 2006 we first wrote about SkySails, the company that wants shippers to return to the age of sail. Well, since that time they’ve grown up a bit and now have commercial product. The idea is simple, harness a large ship to a kite/sail with a large area (~600 m²) about 300 m above the surface where the winds are stronger and more consistent. The result? Up to 15% savings on fossil fuel consumption by letting the wind help out.
