[Stoves] Very small stoves and reheating food

Hi to all,
Gus has made an important observation that I simply left out. That is:
There are various stoves that can do the very small cooking. Alcohol
stoves are one type. But many people (except the extremely poor) also
have several different stoves. And they use different fuels for
different tasks.
One aspect about the very small stoves is that they must be fast to
ignite and provide heat. The more advanced fuels (electricity -
including micro-wave cooking, keorsene, LPG, alcohol, etc.) have been
around for a while.
I guess my thinking is swayed because of realizing how TLUD stoves
(among all of the dry biomass stoves) can be in the category with those
that use more advanced fuels. And this can be especially true if the
dry biomass is pellets, which represents a more advanced form of dry
biomass fuel.
In the end, it all boils down to what the stove users want and can
afford and have available. I know that my wife prefers the micro-wave.
