G'Day, Well nanotechnology was my game for 14 years and I had the good fortune to work with ANU. The strength of composite fiber resin materials doesn't just reside in the fiber but in the nature of the fiber resin interface (You probably know the bundle of sticks analogy). I didn't work with the ANU group you referenced but from general knowledge of the area will guestimate a 20lb sea kayak as strong as my Pittarak in 5 years time. (Of course some foldables are almost that weight now!!) Suspect most of the delay will be in getting production quality QC systems in place. For an equivalent strength 10lb kayak someone will have to work on a lightweight strong resin. (but don't go making investments on my say so:~) All the best, PeterO (Whos in India next week so forgive slow replies) *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
