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.

Thanks.
