Well I suggest they don't bother and I cannot see a spreadsheet but we all
know biomass can be converted to char. My point remaining that to release
heat from wood you need to add oxygen and the fact the wood already has
oxygen containing molecules within it is irrelevant.

bonded to an oxygen or carbon atom, oxygen has to be added to extract heat
from the wood. The same is true for other partially oxidised hydrocarbons
like methanol, acetone or ether.

Okay I shan't comment on the rest of your *non* sequitur diatribe below but
please don't worry about embarrassing me, if I am wrong I admit it, I am
also not a chemist nor ever claimed to be.

Get your chemistry advisor to comment directly  because even if you do
understand the science you are using it wrongly.
