I was watching some videos made by Dr. Victor Fursov from Ukraine where he was touting the advantages of new frame design. In the videos, the brood nest and supers had frames that were 90 degrees to each other and had no space between the top of one frame and the bottom of the frame immediately above it. The claim was that because the two frames contacted each other at a 90 degree angle, the bees would build comb from one section to the other and be able to move directly from one colony section to another. Am curious if anyone has tried using that approach and with what results, or if anyone has any other information on Dr. Fursov.
