Is the Double Channel Wing Design an Improvement?

[roineust]

Can anyone take a look at the following video, and then look at the attached drawing, and tell me: Why shouldn't the design described in the drawing, improve upon the channel wing lifting force?

Here is the video:

P.S.
Just found the following image on German Wikipedia Channel Wing entry, which gives me a hint that it indeed might be an improvement of design:

One way or another, the air has to be directed downward to produce lift. Blowing it horizontally over/across a wing is a really inefficient way to do that (sucking it over the wing is even worse)...as the results in the video show, with the thrust produced being about 5x the lift produced.

I'm sure it would -- but you should be able to predict how much of an improvement based on the results in the youtube video, and show yourself why it is still a really bad idea.
