[Stoves] more on ocean acidification

Hi Tom,

I was impressed at Stove Camp with Paul Anderson's, M. Nerhuda's, Art
Donally's, etc. new TLUDs. Advances have been made in the clean burning of
biomass in TLUDs and the turn down ratios are better. I think it may be
fairly accurate to say that generally less primary air was often seen as an
improvement?

I  mention the improving trend because household scale TLUDs (that can make
biochar when it's desired), in my mind at least, are becoming more of a
technologically ready option.

Stoves that meet the Global Alliance suggested levels of performance are
meant to address both health and climate change. This seems to be right up
their alley for a new generation of found fuel and prepared fuel burning
natural draft TLUDs. I guess we'll see from field tests in the next couple
of years.

I'm very much looking forward to Jim Jetter's TLUD webinar on August 20! A
natural draft TLUD did as well as some fan stoves on some measures and
wouldn't it be great to not need electricity for clean burning.

Best,

Dean
