How do you decide on those figures from this discussion?

My inference from recent discussions here  was that a small PV
solar-battery combination was more likely to be cost effective than a
TEG IF it was decided that a fan powered stove was "worthwhile".

I come from a country with a well established and reliable grid so I
can only but imagine what I might value of the utility of a small
amount of electricity. I suggest that powering a smart phone and
lighting would be high on that agenda but it would be interesting to
see the price/demand curve as electricity gets cheaper, I think it
would have to fall a lot before cooking with electricity becomes
economic. My cooking is almost exclusively done with electricity but
that cost is a very low percentage of my income.
