[Stoves] Hi TLUDers -- and EPA testing questions

[Dean Still]

Hi Ron,

Paul, Christa, Paal, Art and others taught at several TLUD oriented Stove
Camps how to make TLUDs. All we did was to change different amounts of air,
mixing, heat transfer strategies to the prototype design under the emissions
hood. The emission hood lets us tune a stove the way cars are tuned.

The TLUD we sent to Jim has a lot of fast air and mixing at the top of the
fuel bed. We have the fuel sitting on a screen letting in as much bottom air
as possible so the charcoal catches on fire and helps to cook the food or
simmer the water. The stove burns up all the fuel. We pay a lot of attention
to making the heat transfer to the pot as good as possible.

I think it's really neat that a stove can either make bio-char or not by
controlling the bottom air so consumers can pick what they want the stove to
do.

Great to hear from you.

Dean
