June 14, 2007 The ambitious WINDREAM ONE project to cross the Atlantic Ocean in a sail balloon driven by natural and renewable energy sources is progressing. Test flights got underway last Saturday with a small prototype balloon designed to test the curved carbon foil which will run under the water’s surface and guide the 900m3 helium balloon’s flight path via a 50 metre cable. The prototype also gave Stephan Rousson an opportunity to test the pedal power and he reports that it was an absolutely brilliant flight which lasted four hours.
