Don't bet any big money cause Dave (usenet wind tunnel) Hyde is right.
Just think, if he was wrong we'd be seeing Biplane Boeing 777's,these guys spend
millions to get a couple percent increased efficiency on their transports.
Better believe if a biplane was more efficient they'd be doing it.
No if's, ands, or buts. :-)

How 'bout a challenge: I can show you mathematically and using physical
relationships why (without aerodynamic treatments like winglets or
conjoined
wings) two wings will produce more drag than a single wing of equivalent
area but higher aspect ratio. Your challenge: Prove the physics wrong.
Show how a second wing will result in less drag. Show me the math.
