Could a bicycle power generator provide enough power to lift an ultralight helicopter

I couldn't find a better article but according to this article,

http://www.popularmechanics.com/technology/aviation/diy-flying/a-human-powered-helicopter-takes-flight

it is at least possible to get off the ground using only human power. I am trying to work on something similar using a bicycle power generator to aid in spinning the prop and getting me some (aided) liftoff! First off is this even possible? Secondly, This thing has to be able to lift its own weight + at least 200 lbs. (me and 30-40lbs cargo, I plan on groceries!) so what so of calculation would that require as far as rotor diameter and how much is the minimum HP I need to get me off the ground? There's probably loads more stuff I'm leaving out from ignorance so if anybody knows something that would help it would be much appreciated! :)

P.S. And I'm not entering the competition so engines/capacitors/whatever are GO for me as long as the primary power source is still my feet!

Why would you use a bicycle to power an electric engine and not just gear it directly to the rotor mechanism? The efficiency loss you would experience would be significant, both in the alternators and in the engine's output. Unless you are planning on using batteries to augment your power input - which would limit the range - I would suggest that you run some efficiency calculations on a geared transmission system...

Also, the possibility of using this to make grocery runs is not practical. If, for example, you got a cramp while pedaling, what would you do? Auto-gyration can only do so much to land a helicopter - once the rotors stop spinning they're pretty much aerodynamic coffins.

Let's put it this way - helicopter manufactures spend millions developing helicopters. Rotor designs are extremely fickle and the fluid mechanics of helicopter operations are complex. I mean, you could run some simulations in CAD and think you have a good design, but unless you've got a degree in engineering or have some serious experience in aviation, I would not suggest you attempt to build or fly anything.

Didn't you see in the article? People have been trying this for 30 years. The best record is less than 20 seconds.

The energy required to lift 200 lb up 1 meter is about 890 J. To do this in 3 seconds (pretty much the slowest climb rate that would result in a practically usable vehicle) would require about 300 W. That's about the average power output of a Tour de France cyclist.

It would be fun if you could build such a device but the reality is that unless you are a great athlete and can design and build an extraordinary machine you cannot generate enough power to lift the weight of yourself and the machine off of the ground.

NO! Bicycle light generator output is 6V AC and current limits to 400mA , just good enough to light up a small light bulb.
