After recent talk about human-powered flight -- Sikorsky has offered
a $250K prize to anyone who can fly a human-powered helicopter to 10'
altitude and keep it there, or above, for 60 seconds.
Since humans I believe can generate less than 1/2HP I think their
money is safe.
World's record so far is about 0.2 meters for 19 seconds.

The most horsepower a human can generate is running up a steep flight
of stairs as fast as possible.
Of course the output will improve if it's a big fat guy doing as well
as a scrawny 150 lb guy would do.
Not likely. Body builders would fare poorly too.
To take advantage of what little ground effect you would have at 10'
the rotor would have to be located
as far down the total assemblage as possible. The hover would be a
little unstable but it could be done.
Bicycle type pedals are a poor way to get top power. You would nee a
rowing machine arrangement.
