That kind of thing is very much of interest to me for whatever larger door I put on the shop building I hope to build. I don't want a "garage door" on it, but need something larger to be able to bring machinery, materials and completed projects in and out. So a carriage door or a flip up panel like the door in the video makes for a good accomodation and they can be insulated to suit as well. Weather sealing should be easier than a multi-panel door, too.
