To answer your question about drag, Greeney.
The drag of an aircraft is the total sum of resistance applied upon the aircraft, this is caused by the air. Anything that influences the way the aircraft interacts with the air in the atmosphere influences drag, so the material, shape etc definitely all have an impact. Material or finish are important to note because a smooth, slick surface will pose far less friction with the air then a rough, porous material would.
Ideally as much of the plane you can make into an effective airfoil the better. Traditionally the wings are the airfoil, like in older planes with wings that are at a near 90º to the fuselage especially. But nowadays military jets have large portions of their bodies acting as airfoils on top of the wings, the B-2 for instance is one big airfoil, it all acts as a wing. So as a result of the shape the plane generates a LOT more lift then it would if it was shaped like an old B17, which means less of the power from the engines have to be converted to lift.
I think his idea should be experimented with extensively, could prove usefull.
BTW esecallum, it wasn't really a good idea to post it on the internet if you actually plan on holding on to the idea I don't think. But then again, I'm not a lawyer so I could be wrong.
"George Bush says he speaks to god every day, and christians love him for it. If George Bush said he spoke to god through his hair dryer, they would think he was mad. I fail to see how the addition of a hair dryer makes it any more absurd."
