[Stoves] Lanny Hanson pot insulator

[frank]

Dear group.
When at ETHOS Lanny sent me home with his stoves and my daughter and I 
have been having fun with them.

Working on a science project we compared a three stone fire boiling 5 L 
water to a pot with, and without,  the pot holder Lanny produced.
Still working out the numbers but what a difference.
1) much less wood was needed. (hot gases squeezed between the pot and 
insulated metal jacket)
2) much less smoke produced from the fire (more draw so more oxygen? or 
longer hot space for organics to burn?)
3) much safer to use because the hot pot of boiling water had a 'jacket' 
of warm metal one could pick up and pour off the water.

Now if Dale could put his fins in the space between the pot and outside 
insulated layer where the hot gases go.......

I can see pots being sold with this insulated jacket with a gap for the 
hot gases built onto the pots to be used on the three stone fire. Very 
simple.

Regards
Frank
