I can probably do 200 Watts "for a while" - but I'm also several times older than you and not a paragon of fitness. My "100 Watts continuously" was the sort of figures that a reasonably fit person could maintain for an hour say. I'd be far more comfortable at 50 Watts and even that would be annoying after an hour. As I noted, keeping airborne requires substantial power. Gossamer Albatross took 2 hours 49 minutes to cross the English Channel. 300 Watts in still air - rather more with turbulence http://en.wikipedia.org/wiki/Gossamer_Albatross " ...The aircraft is of unusual "canard" configuration, using a large horizontal stabilizer forward of the wing in a manner similar to the Wright brothers' successful "Flyer" aircraft. The Gossamer Albatross was constructed using a carbon fiber frame, with the ribs of the wings made with expanded polystyrene; the entire structure was then wrapped in a thin, transparent plastic (mylar aka PET film). The empty mass of the structure was only 32 kg (71 lb), although the gross mass for the Channel flight was almost 100 kg (220 lb). To maintain the craft in the air it was designed with very long tapering wings (high aspect ratio), like those of a glider, allowing the flight to be undertaken with a minimum of power. In still air the required power was of the order of 0.4 horsepower (300 W), though even mild turbulence made this figure rise rapidly. The Albatross I is on display at the Smithsonian Institution's Udvar-Hazy Center."
