Human Powered Helicopter Aims To Break Records

An anonymous reader writes "A team of 50 from the University of Maryland has developed a human-powered helicopter, 'The Gamera,' which took two years to complete. The size of the helicopter is one third of a football field. The helicopter is made from light materials such as balsa, mylar, carbon fiber and foam and weighs about 210 pounds. The team aims to have it hover at least 3 meters off the ground."

Stored energy

I'm sure they wouldn't allow a helicopter that uses air earlier compressed by the human pilot so what about stored momentum in the blades and machinery? Also do air currents count as stored energy? Obviously this couldn't fly without the ground effect [wikipedia.org]... Just some thoughts.
