here is the buisness end of his patent,, flat metal shaped to a corrigation vertically to which then the efforts to bend it around in a circle naturally promote interlocking of the two ends.
the areas curved away from the tube it surrounds would act as a chimney and as heat is produced, naturally it goes up, yet the base would suck cool air in.

I really like it actually, but a part of me says it has to in some fashion actually "trap" heat as well.

in my design i am trying to attach metal to the hottest glass area of heat prodution then pull it up and away. mine is more complicated than his as far as work efforts are concerned to deal with heat,, his is more cost affective and probably does work.... i did not mock up or try his method.
