RE: [papercreters] PAH

I have been following Don’s webpage for quite some time it would be nice if he updated a bit more frequently.  Depending on the depth the tubes go in the ground I may have enough elevation on my site to use only gravity.  How deep are your tubes going in?  Are you using 4” solid plastic tile?

I had the great fortune to meet Don Stephens (www.greenershelter.com), solar architect/engineer.  He designed a brilliant passive annual heat storage system for Jerry and Marilyn Mueller's new home on Mica Peak in eastern Washington.  I was privileged to see the system in use and look at Jerry's log of the temps at the various sensor points.  Very illuminating.  He'd been keeping track of the ground temperature since building began.  At 4 years of running the system he was nearly at his thermal battery conditioning goal.

 

The Mica Peak (Mueller's) system uses a solar chimney, which I don't want, so we've worked out a different system that uses solar powered fans and loops that begin and end in the collector.  The air is drawn through the ground loops (multiple loops per collector) very slowly to allow the heat to be absorbed into the ground.  The fans will come on when the box temperature is X degrees higher than the ground temperature.
