[Stoves] Char from bagasse

[Paul S. Anderson]

Frank,

I think that I am not understanding something.  Are you saying that  
raw bagasse will become char when subjected to temperatures of about  
75 deg C and higher?  I think we need temperatures of over 350 C.  The  
temp of 75 C does not even drive off the water vapor and is not even  
torrification temperature.

I am missing something.
