From the article:

WINDREAM ONE is an ambitious enterprise : to make the first successful “aero-maritime” crossing of the Atlantic powered solely by renewable energy sources. The idea is not really to establish a record, but to prove that it is technologically possible to cover a distance of 5 000 km flying night and day using sources of energy drawn from the sea, the sun and the wind. All those involved in WINDREAM ONE wish to participate in a new chapter of aeronautical history, in a context were they contribute scientific knowledge and skills current thought on fundamental choices for tomorrow’s energy solutions, a field where Theolia is a forerunner.

Also:

Sun and wind are the main sources of energy for WINDREAM ONE, but the sea will playing a major role in this technological challenge. WINDREAM ONE is a dirigible 900m3 inflated with helium. She is 93 ft 6 inches (28.50 m) long, has a «chien de mer», a curved carbon foil which will be under the water’s surface. It is linked to the balloon’s car by a long cable whose length can be adjusted from 65 ft 6 inches to 164 ft (20m to 50 m) and which acts as a centreboard. This appendage assists the crew in controlling the flight path.
