      Anyone doing solar thermal here? Perhaps Morris?   
      
      I've just reworked my Kreamer style pass through collector. 25' * 8'   
   of south facing collector (+ another 16" on top). Black felt for the   
   pass through, SunTuf glazing with a layer of mylar underneath for double   
   insulation. I'm drawing the air out and ducting it into a collector box   
   and then distributing that into the heating vents. I'm getting about   
   ~16,000 BTUs/hr (20F delta at ~650 CFM) when the sun shines, but I   
   suspect some unfound leaks.   
      
      I've got the collector divided in half so I can throttle down half   
   when it falls in shade. The collector sits slightly to the west of due   
   south and solar gain starts about 3 hours after sun up.   
      
   If anyone is working on something similar, I'll post up some pics and   
   data. There is a lot unknown to me at this point.   
      
   One of the other projects has been the solar cabana, which has the roof   
   (formed of 3/4" 10' irrigation PVC, ie thin wall) glazed in corrugated   
   polycarbonate with vinyl under. The sides are all single wall vinyl (~8   
   * 10' footprint). That heats up nicely, well into the 80's on a blustery   
   40F day, but of course loses heat rapidly at sun down. But during the   
   day a delight to pour a glass of scotch and image myself in the tropics.
