[Stoves] Lanny Hanson pot insulator

[Robert Penn Taylor]

Frank,

I've been thinking along similar lines since seeing Dale's pots at 
ETHOS. There might be a significant per-unit cost involved to produce a 
pot with fins and an outer jacket, but it may turn out to be worth it 
from a fuel usage and cleanliness perspective. The big advantage (other 
than phenomenal heat transfer efficiency) is that if done correctly, the 
outside of the "pot" (actually the built-in insulating jacket) would 
never get sooty, and the nice shiny metal that so many people find 
attractive would stay nice and shiny. The jacket would also protect the 
fins from impact and abuse. It would be interesting to get a production 
cost estimate and see if the expense is worth it.
