Stovers, and Gasifier folks,
Let's give a big round of applause to Colorado State University and also
to Envirofit for their strong entry into the world of gasifier cookstoves!!!
One million dollars worth of encouragement for a strong entry is
fantastic. Congratulations. Details are at:
http://www.news.colostate.edu/Release/6485
The press release states:
"It [semi-gasifier] separates the combustion process into two phases.
In the first phase, combustible gasses are released from solid
biomass. In the second phase, those combustible gasses are mixed with
air and create a secondary flame," Tryner said.
I think that definition is a good one for "gasifiers" and is certainly
how the term has been used for a decade and more regarding cooking
stoves. So I will ask the first question:
Please define the difference between a "semi-gasifier" and a "gasifier"
in the terminology used by CSU. (I hope you just drop the "semi-" part.)
The folks at CSU do GREAT work, and I am sure that their entry into this
aspect of improved cookstoves will result is some great benefits.

However, the general consensus is that only forced-draft gasifier
cookstoves deliver remarkably low emissions, whereas natural draft
gasifiers tend to be similar or only marginal better than most rocket
stove designs. This is an impression reinforced by my own (very
limited) work, as well as by the attached recent paper by Abishek Kar of
the Surya project. In contrast, the recent paper by Jim Jetter's group
is more difficult to interpret, and includes a natural draft gasifier
with better high-performance emissions than all other stoves tested, as
well as a forced-draft gasifier among the worst performers. Go figure!

Apologies for the lack of communication here- I was away all last
week at the ASA-SSSA-CSSA conference. No new stoves/biochar news at
the moment; I'm totally preoccupied preparing for my prelim exam for
the next several weeks.
Hope you well,
john

John,
Sorry that you and Hugh did not meet when he was in Boulder last
week.
Are there any more developments involving you and stoves and
biochar?
