[Stoves] Torrified Pellets

[Dean Still]

Dear Ron,

We had three women interns here at the research center for a summer who
found cleaner burning recipes for the TLUDs gathered from the surrounding
forest. Some things like bark make smoke, etc.

Many pellets smoke when using eucalyptus, etc. Different mixtures of
kerosene make more or less smoke in off the shelf stoves.

I'm wondering if torrified pellets will burn cleaner than normal pellets.


Best,

Dean
