Hi Daryl, thanks, and i would think if this is feasible at all, it would be really hard to do in a DIY type project.
Hi Franco, yes, that thought occurred to me as well, but there might be ways around this. Speaking very theoretically, say you used a very fine dyneema thread and in a very simple and more open weave pattern, then slightly calendared the threads to "spread it out" (flatten) some, and then used nano technology to attach the shingle scales, it might get the weight down enough to be feasible (it's also highly dependent on what material you are using for the shingle scales)? But no doubt it would be very expensive to produce! Hey, but then again, it's not unheard of to hear people spending 400 or more dollars on a WPB jacket anyways.
(one problem with using dyneema thread is that it's super, super conductive-- i have some safety sleeves with a lot of dyneema in them, which i use for motorcylce riding, and it's amazing how fast and easy body heat passes through!)
btw, good to see you again.
