In one diplomatic word - Crap. You are mistaking the power requirements to lift off vertically, ala space shuttle .. as compared to the power required for a gradual takeoff, using wings, as all normal planes do.
If Bert Rutan can get a purely solar-panel-driven plane off the ground and up to many thousands of feet .. surely Yves Rossy can organise a little larger wing span to give him the necessary lift to enable a standard style of takeoff ..
Must say .. I gotta admire the guy. I reckon you'd need cojones the size of base jumpers to strap yourself to a barely controllable set of wings and motors, and in effect, turn yourself into a borderline human missile .. with all the potential for going out of control, that entails ..
