one grams of wood (186 LB cooked weigh, 50 lb dry with 10 LB. of wood,
giving credit for the left over char) and my ¼ thick aluminum pot only gets
about 10 to 12 grams of rice or 10 grams of pinto beans.</FONT></P>

<P><FONT size=5>I believe the heat flows across the rounded bottom of a vat and
spreads out better than it does when it dead heads into the flat bottom of a
pot. I could be wrong about this last statement.</FONT></P>

<DIV>With my little gasifier, I always try to keep flames well underneath the
pot. But if really high heat is needed, and if the pot is a bit small, flames
will come up the sides of the pot. I imagine that the pegs of the Cajun Rocket
Pot will transfer more heat to the pot, and they will slow down the flow of
hot gases. In Louisiana such big pots are quite common for boiling seafood,
especially crayfish, and for making gumbo. Big pots are also needed in Vietnam
where it is quite common to boil bones for many hours to make a stock for
noodle soup. If the Cajun Rocket Pot achieves a 50% increase in the transfer
of heat (as claimed in the video), this would be hugely significant,
especially in a commercial setting where noodle shops can consume a bottle of
gas in three days.<BR><BR></DIV>
