Stove Camp will be held July 27-31 at Aprovecho's Blue Mountain Campus. Participants will learn about the design, testing, funding, and marketing of biomass cook stoves. Bring your ideas and your prototypes. Two emissions hoods will be available all day to give a rough view of your stove's emissions performance (1). Materials and expertise will be available for you to construct new stoves and modify existing models. There will be ample time for discussions among colleagues between lecture sessions, during moderated discussions, during work sessions, and during meals.</span><o:p></o:p></p><p style='margin:0cm;margin-bottom:.0001pt'><span style='font-family:"Tahoma",sans-serif;color:black'> </span><o:p></o:p></p><p style='margin:0cm;margin-bottom:.0001pt'><span style='font-family:"Tahoma",sans-serif;color:black'>The coveted Kirk Smith 'Cat Pee' Award along with the $250 prize will be awarded to the team that produces the cleanest burning stove. The WHO guidelines for PM are very difficult to meet - 1.75 mg/min for an unvented stove and 7.15 mg/min for a vented stove. Can you pass the test? If during Stove Camp a stove is found that appears to meet the WHO standards the owner will be invited back to Aprovecho free of charge so that the stove can receive extensive testing. Aprovecho will produce an official report for the owner to use at his or her discresion.</span><o:p></o:p></p><p style='margin:0cm;margin-bottom:.0001pt'><span style='font-family:"Tahoma",sans-serif;color:black'> </span><o:p></o:p></p><div><p class=MsoNormal><span style='font-family:"Tahoma",sans-serif;color:black'>Space for tent camping will be available.
