For years the corporate motto has been ~ 'We move more than hot air',
Then, just when some of the airhead ideas were starting to solidify, the **** hit the fan.

The intent of the UniCopter (http://www.unicopter.com/UniCopter.html) is to bring together in a new helicopter a number of 'advanced' rotorcraft features,
Features such as; · Laterally located counter-rotating main rotors
· Extremely rigid rotors
· Slow turning, wide chord, high solidity rotors
· Advancing Blade Concept
· No tail rotor
· Pusher propellers

Well I'll be damned. Some dude by the name of Sir George Cayley came up with the very same idea 150 years ago.

from Helicopters and Autogiros ~ "Cayley made these drawings for a vertical take-off and landing aircraft in 1848.
Although the design looks fanciful by modem standards, it has features that have appeared in successful helicopters (the wide fanlike rotors resemble those used on the deBothezat machine flown by the U.S. Army in 1922; the lateral side-by-side arrangement of the rotors is similar to the recordbreaking Focke helicopters built in Germany in the late 1930's).
One especially interesting feature is the design of the blades: they flatten down to form a solid disc and act as a wing in forward flight.
The bird's-head bowsprit may have been a deliberately humorous touch."
