Kevin;

First, let me apologize for not getting emissions testing done for you at
Aprovecho. Life seems to get in the way sometimes - especially when you're
older and events crop up suddenly.

The metal band with the stocks upright is probably a better way to make use
of the maize stocks. From watching your videos it is clear this is
functioning as a hybrid between TLUD's and flame caps. Do you make any
attempt to regulate the air from below? When we go to Aprovecho I can
easily make a band and we can do emissions testing on this new arrangement.
I still plan to compare emissions of dried maize stocks versus maize stocks
at ambient relative humidity. I think there will be a difference. I'm also
planning to do this in a metal band versus the "conservation burn" style
you originally worked with. Let me know what you think.

Norm
