Thanks a lot Crispin, as usual, for a very insightful answer. We did a very similar thing for our gasifier where we took out a small stream of gas and passed it through a cotton filter, weighed it and knowing the gas flow rate could correlate particulates with the power/energy of gasifier. But that was with a big system (150 kW gasifier unit) etc. With the small size of stove and free convection of flue gases it might be little tricky but I am sure it can be done.
I will also be very interested in Tami Bond's invention. Do you have her email so that I can write to her. Thanks again for the help.
