Dear Dr N

The 15th picture

has a slit and twisted top on the can. There is attached a stove developed
by an industrial design student at the University of Johannesburg (one of
two that rated as being really interesting out of a dozen entries). I don't
have a specific suggestion for you, but the slitting and folding in at the
top brought slightly pre-heated air into the gas burning section. It is a
way to get a vortex going without adding additional metal.

Regards
Crispin
