[Stoves] Hybrid cooking-stoves: solar+fuel?

[Boll, Martin Dr.]

Dear Crispin,

Since sometime, I am thinking how to pre-warm primary and secondary-air, in
order to get a better blow without fan.

One idea was, to pre-warm air in a concentrating solar-trough, or just by a
mass with black surface, possibly covered with glass.

The second step in reflecting then is:

 

 Why do we not think of hybrid-cooking-stoves: combined solar-fuel-stoves? (
whatever fuel)

 

In a certain time before starting the fuel-stove, solar heat-collection
could be done in advance, so the fuel-stove could run with less fuel, but
getting a powerful output. The power of the solar-collector I guess can be
between 300 and 1500W.

Advantage was: quickly speeding up the fire and simmering by collected
sun-energy. Cooking would work by different weather-conditions, not only by
sunshine.

Was it worth to try a bigger-scale simple pre-warming of air for your
Libhubesi-stove?

 

Regards
