[Stoves] Results from Vietnam on emissions, biochar and its use in toilets and pig pens

[Alex English]

Hi Stephen,
Figure 5 in the study raises questions. CO ppm should be referenced to 
excess air from measurement of O2 or CO2.
I cannot imagine three separate tests following such similar patterns. 
It is as though the peaks and valleys were traced.

Kinda jumps out at me.
Alex
