[Stoves] Aprovecho Stove Camp

   Apologies for not getting off a Tuesday summary.  Now almost done with Wednesday.  I will try to answer various early questions (photos, simmer, etc) later.   I have seen some new design ideas here - but most stoves here will be familiar to list members.  Testing being done seriously.  Considerable changes in designs after a test.

  I have been waiting for at least ten years to make spherical briquettes (spherequettes?) as this has been a recent project for InStove (their briquettes of (maybe 2"x2"x14" shape made in large press of their design, mine 2" diameter sphere made by hand).  Probably can dry by Friday and test in Art Donnelly stove (the biggest here).

  Had nice long conversation with smallest stove herel (camper type) developed by Kirk Harris.  More coming on that.  Many new design ideas.

Last night everyone could make their own pizza, which were  cooked in wood oven.  Beer available.

This AM nice presentation by Dean Still on range of stove topics he has been working on.  Nice new large kettle available from StoveTek,  with built in skirt.

Paul Anderson' son Simon showed nice split screen video of real time diagnostics chart and changes happening with stove.  Speeded up by four, but could be 8 or 16.

Paul and Art Donnelly showed a wide range of TLUDs.  Aprovecho has a museum of at least 100 stoves ( most with test data)

more coming.
