It all sounds logical to turn a low emissivity flame to radiant heat
like this and heat transfer seems the next area for big improvements
with a clean burning stove.

I imagine as long as the wires are kept above the autoignition point
of the gases in the flame or the flame has completely burned out
before touching the strainer there won't be much effect. I wonder how
this sits compared with the wire gauze in a Davey Safety lamp, which
is there specifically to remove the source of ignition from the gases
outside?

Have you managed to analyse the offgas before it is burnt to see if
the blue flame is down to CO or just good premixing?
