Nanowood for superior insulation. Supposed to be better insulation than aerogel. http://www.latimes.com/science/sciencenow/la-sci-sn-nanowood-20180309-story.html

The same team who invented super wood.  First they do killer structure, now amazing insulation.  Coat with epoxy.  Someone will not want to hear about this…

This could be very good structural insulation for future multihulls.  Maybe even a lower cost structural core material.  Especially if it keeps the great fatigue strength of wood.
