It's a video of a human powered helicopter. A thing of beauty and

utter uselessness. ;-)



An autogiro would be more useful. The father of a childhood friend

built one in his basement. IIRC, it had both pedals and a petrol

engine - it actually flew.



I don't think that would count as "human powered". The pedals were

presunably just a way of spinning up the big rotor from rest while the

petrol engine provided the forward thrust. Once there's enough forward

speed the main rotor just "windmills" and needs no direct power source.



Besides, we're not talking "usefulness" here, we're talking about art. ;-)

If they can't find a use for the $250,000 Sikorsky prize I'll have it.

there might not be much left once they've paid the bills ;)
