Hi All,

Here's the announcement of dates for Aprovecho Summer Stove Camp July 27-30

at the beautiful Blue Mountain campus. My newly built 23' Scottish coastal
rowboat ("Sanctify") will be

in the water at the nearby lake and everyone is welcome to go for a
row/sail.

One theme ($250 prize) will be:

"Best Stove Meeting World Health Organization Indoor Air Guidelines".

Best,

Dean

*The FireFly: A TLUD Lantern Stove and the Well-Tuned Rocket Stove*

Studying the TLUD (Top Lit Up Draft) stove unified our thinking about how
clean combustion can be described. Both the Rocket and TLUD can be cleaned
up by following the same design principles:

   - Only make the amount of gaseous fuel (by heating wood) that will all
   flow into the flame above the fuel. (Lean mixtures usually burn cleaner
   than rich mixtures).
   - The gaseous fuel must be supplied with enough air to fully combust.
   - The flame, air, gases, and smoke must be completely mixed.
   - The very well mixed gaseous fuel must reside in the flame for a long
   enough period of time to completely combust.

The FireFly Lantern/Stove illustrates how these principles can be applied.
Very little primary air enters the fuel from below limiting the rate of
gaseous fuel production. The forceful secondary air jets supply enough air
and mixing to prepare for successful combustion in the flame. When the well
mixed gases remain for a long enough time in the vertical column of flame
almost complete combustion occurs.

The Rocket stove functions in the same way. Burning only the tips of the
sticks meters the amount of made gaseous fuel. Burning only the ends of the
sticks creates the amount of gas that will all flow up into the flame above
the fuel. When the gases are well mixed (usually with forced air) and
reside in the flame long enough very clean combustion results.

The FireFly will be available for purchase very soon through

             *Summer Stove Camp **2015 **July 27th-30th at Aprovecho
Research Center*

Aprovecho's Summer Stove Camp is back! This is an opportunity to conduct
lots of emissions testing of stoves “under the hood” in the lab and in a
Test Kitchen.

Stove Camp is open to everyone, and is regularly attended by – designers,
producers, program implementers/administrators, folks interested in
environmental issues, women’s advocates, student interns, and some amazing
inventors. We all share the goal of serving humanity – particularly in the
developing world – by finding viable solutions.

Stove Camp encourages participants, and shows them how, to solve stove
problems. One year NASA participated and we combined emissions equipment to
do experiments on Black Carbon. Working with GIZ the participants at Stove
Camp 2012 revisited and did further exploration and analysis of charcoal
stoves. Participants have open access to the emissions hoods and sometimes
spend the whole week tuning their stove.

People have the option of camping out by the river at our new beautiful
campus at Blue Mountain, or choosing one of several affordable
accommodations, in the small Oregon town of Cottage Grove.

Stove Camp is unusual because there are unique kinds of learning
opportunities all around you.
We expect a large turnout this year, so please reserve a spot soon!
