Crispin,
If the wood is high quality like well seasoned oak the water I am boiling does
not take on a nasty flavor. But of course high quality wood will be rare so a
lid may be necessary.
I have worked with hopper fed designs mostly charcoal cookers. I have one that
will hold steady temps for 48 hours without refueling. You do have to pull the
ashes every 12 hours though using briquettes.
Me and my senior cooking partner cooked 2000 LB of pork for Habitat for
Humanity an org that builds houses for the poor* with 4 cookers that I designed
in two cooking sessions. We have another cook for the Knights of Columbus a
Catholic org, this Labor day. I do two charity events a year.
*The poor in the USA should be called the "Impovrich". Hopefully soon I will be
able to help the "real poor" to which I have more sympathy.

Dear Lanny
Thanks for the interesting review. I think it will be of interest to the
viewers to know that a pot heated all around will probably have to have a lid
on it to prevent the food absorbing smells from the combustion. This is so
important in certain regions that users can be observed waiting until 'a
certain point' during the ignition of a stove before putting on the pot to
avoid any contamination.
There are cases where the smoke is desirable but that is more unusual.
So there is no big issue for the cooker, it is just that the lid will
probably have to be on when cooking and the flat lid-thing will have to clear
the handle.
I like the side loading. It is one approach to refuelling TLUDS's (top-lit
updraft-started stoves). There is a variation on the theme in Mongolia which is
a TLUD with hopper fed continuation, and it generates >50 Watts of electricity
too.

The TLC burner ("Top Lit Combustor") is new technology. I believe it is step
forward toward improved biomass cooking stove design.
The TLC is a batch-fueled burner to which you can add fuel without creating
smoke to boost the heat and extend the cooking time.
This video demonstrates the "Top Lit Combustor" and the 'School Lunch
Cooker's" amazing capability to burn damp and wet wood outdoor in the rain.
Even adding a chunk wet concrete block does not stop this burner.
The "School Lunch Cooker" uses the "TLC burner", and my "Exhausted Pot
Shell" to cook outdoor in all weather.
This stove just wants to cook!
