Tips and tricks;

The cone shroud captures the heat off the side of chimney and the taper allows a larger area of the pot bottom to be heated, but the largest performance increase is if your pot or frying pan covers the Entire area of large diameter of cone it traps the hot air under the pan and temperature gets hotter. If you put to small a pan on top the heat escapes to rapidly and low cook temps result.
  Also key is to cook or boil with a pan lid cover, this lantern only puts out about 700-900 BTU so "keeping" the heat we have is key to working well.
  Finally I am using "ultra pure" lamp oil, some say kerosene burns hotter but more smell, I like the Ultra Pure lamp oil as I almost can not smell it inside, and kerosene gives me a mild headache indoors so I will only use outside.
 
The parts in photo cost me approx $15 total.
From left to right is heat cone/lantern/roof.
  You can just snap roof back on if you want to go back to lantern light.
  I welcome any questions or thoughts to refine the lantern/cooker.
