"Wel then, we might as well close the patent office because everything that could possibily be invented has already been invented.............. "

As far as what those designs show there isn't anything there that if they were patented the patents would have expired a long time ago.

Exactly, there is nothing new in any of these designs. They have never been used on commercial aircraft for a reason.

Example: Delta wings SUCK at low speed. Current commercial wing design is a compromise between straight wing (excellent lift, high drag, and poor high speed performance), and a fully swept, or delta wing (low drag, great high speed performance, lousy low speed performance requiring much higher take-off and landing speed)
