| Free energy | |
| "We're absolutely excited," said Verena Frank, spokeswoman for Beluga Group, SkySails GmbH's partner. | |
| She told the BBC's World Today programme that the project's core concept was "using wind energy as auxiliary propulsion power and using wind as a free of charge energy". | |
| "Nevertheless, it differs very much from traditional sailing, as we do not have any bothersome mast on deck which might be a hindrance to cargo-loading operations." | |
| Ms Frank said the efficiency of the kite depended on wind and weather conditions. | |
| But the advantage of the SkySails system "is that you do not need only backward winds - there can also be side winds and you can still set sail," she said. | |
| She said the kite could be used on medium-size cargo ships, cruise liners and trawlers. |
