Very interesting history... As an inventor myself, I'm now wondering how the efficiency of such a wing compares with current/conventional airfoils... Hmmm... Tetra wings would certainly be strong and relatively easy to build, but they look like they would have a lot of "drag."

Interesting! Yeah I'd bet there would be a considerable drag problem. I was wondering also about the location for testing these (up in Novia Scotia.) Do you think that the naturally cold air had any positive influence on the airflow of these designs?
Cold air == improved density-altitude, and so it seems likely that it would. :)
One really cool characteristic of a tetrahedral wing flying machine would be that it would be pretty easy to make it collapsible/foldable... How about a man-carrying wing that you could fold down to backpack size? :) :) :)
Guess that's why they're all wearing jackets! A backpack that could unfold into a flying device like this one would be incredible! Maybe one day... :)
