HI Paul
Nice work. We should talk as our work is very complementary to yours. We did our tests at CSIRO division of atmospheric physics in Melbourne

In large gasifiers I have tested a linear relationship between fuel bound nitrogen and NOX. I haven’t tested this in TLUDS but I would expect the same result.

NOx is not associated with TLUDs because the temperatures do not get high enough (that is my understanding, but not my field of expertise). And the same applies for CH4. The TLUD devices that are the sizes of 200 L drums are constructed with a final flame as the gases exit. CH4 should not be able to survive that flame area.

For ETHOS 2015, there will be numerous independent presentations that relate to TLUDs, so I will NOT be summarizing about them. But I will present the findings of those who cannot make it to the ETHOS meeting, or who only want a short summary of their work.

> Numerous advances in TLUD and other micro-gasifiier cookstoves that occurred in 2014 have their own presentations at the ETHOS 2015 conference. This presentation is an overview of additional work and status reports that otherwise would not be presented. With one or two slides from several TLUD stove projects, the range of diversity of approaches and underlying issues are seen on a world-wide basis. The presenter is in contact with potential contributors, organizing their inputs, and presenting the diversity of results.

Same applies to Crispin with both Mongolia and Indonesia TLUD information. Less likely to attend are people with TLUD efforts ongoing in India, Cambodia, Vietnam, Uganda, Kenya, South Africa, USA and El Salvador (I have direct contact with all of them), and am sure that 6 to 10 others might respond to this contact requesting them to provide some short summary info. It will be SPECIFIC to TLUD and related micro-gasification. I am not trying to cover all types of stoves.
