The human-powered planes that have crossed the English channel
required something like 2.5 HP (about 2000 Watts). That's about the most
efficient plane you can make that'll carry a person. Try peddling like
2.5 horses for more than a few minutes and see if you'd like to "land" yet

You're off by an order of magnitude. The Gossamer Albatross flew on 1/4 to
1/3 hp.
See "Gossamer Odyssey" by Morton Grosser for lots and lots of details.
