[Stoves] TLUD stove is fragile, traditional stove is robust, no stove is antifragile

[lh cheng]

TLUD stove is efficient but fragile. this fragile concept comes from a book
"Antifragile", written by Nassim Nicholas Taleb, like Dr Anderson, he is a
Doctor and professor. He have a good understanding of man-made artificial
system, have deep insight of the weakness of some man-made system, and he
find a good way to make money (of no small amount ) through it from
financial market.

Fragile thing like Titanic ship, is high efficient, beautiful, but there
were big risks, which cannot be avoided anyway, underneath the surface,
when something wrong happened eventually, inevitably, no one can afford it.

I criticize TLUD stove here, not in malice, but try to make something
clear, maybe we can find out the hindrance of its popularity, find a
direction to improve it, and help the user to use it in a safer way.

TLUD stove separates gas combustion from gasification, and is batch-feed,
this combination create efficiency and convenience, but also big risk. many
thing can cause the fire ( gas combustion )  go out, too much or too little
gas, too much or too little air, temperature too low, (too much or too
little prmary air, cause too much or too little gas, both can lead to
extinguish of the secondary combustion), too much moisture in the fuel.
once the fire go out, great smoke jet out like crazy, poisonous, and the
fuel is burning inside the inner cylinder like crazy, no easy way to put
out the first combustion. it is very dangerous and bad situation for
housewife, neighbors scared by the big smoke, people even can got killed by
the poisonous gas. (when water can't low down the charcoal temperature,
water H2O can be turned into poisonous CO gas immediately).

Traditional stove have no such thing, because it is not batch-feeding, not
burning in a tight closed space. and safer in unexpected situation. it is
robust. that's why people prefer it over TLUD stove maybe.

I have no clear idea yet, I just typed this message, not thinking it
thoroughly.

best regards
