Ja, the problem with an open foam structure is that the stress is too
difficult to analyse everywhere.  We need to optimize the disign so that all
the material is stressed about the same everywhere.

Regarding an open Fuller design (to allow the wind to blow thru the
structure) has some promise, if the intention is to make a support structure
for a linear launcher.
