Subject: CRYONICS - foam thickness


Regards foam costs - foam can be cheaper in large slabs, it depends on how
it is made.  Years ago,  friends of mine made floating docks out of foamed
polystyrene;  they worked with slabs that were 4 feet by 4 feet by 8 feet.
Handy tip for working with foam - run lots of current through a thin wire
and pull it taut, and you can cut through foam like a cheese cutter ...
but I digress.  Later on, one of them went on to become a civil engineer,
and designed the approaches to the I-205 bridge over the Columbia River.  
Concrete reinforced bridges are made with boxed sections, containing large
hollow cavities to reduce weight (same theory as bicycle frames), and are
usually poured with wooden forms.  My C.E. friend replaced the forms with
HUGE chunks of styrofoam - and left them in place after all the concrete
was poured.  It was cheaper and faster than the wood, and wouldn't rot in
place.  

Perhaps we should be storing patients inside bridge approaches.  I'm told
the Mafia has been doing it for years ... :-)
