[Stoves] Fwd: 2015 Stove Camp at Aprovecho Research Center

[Dean Still]

Dear Crispin,

I think that the WHO figured on only 75% going out of the room up the
chimney.

The thinking is that the smoke comes back in the windows, the stove leaks
into the room, especially when the pot is removed, or from back drafting,
etc.

I've seen some of this in kitchens but it is strange to me that "Indoor
Emissions" is used for a measurement of CO and PM2.5 out of the chimney.

The biomass stoves that scored less than 1.75mg/min PM2.5 in the Indonesia
tests are so great! If an inventor sends one to Stove Camp it will very
probably win and he or she wins the $250 prize!

We'll pay for the shipping!

Best,

Dean
