But its a lot less sexy too

Richard your system is more akin to papermaking where the fibres are
separated from the rest of the wood and then dry on a mesh which
eliminates the air spaces, paper has a density >1 whereas the dry raw
wood will be around 0.4 and of course chipping increases the bulk
density such that 1m3 of dry wood weighing 400kg will occupy 3m3.
