Safety of Wood Gas [Gasification] storing wood gas.

[Harmon Seaver]

   Oh, ya, damn, I always forget about all that N2. That's always a
big kicker in any producer gas equation, but somehow I only think
about the volatiles. With N2 being the major component. Duh.
    But anyway, thanks for the exact cool down.   8-)
