[at-l] OT Outdoor Furnaces was Geo-Exchange -OT

[camojack at comcast.net]

My plan involves retiring to a place that averages in the 70º-80º range in the daytime, and in the 60º-70º range at night...all year long.
(With at least one windmill, and LOTS of solar panels)

When I'm using my fireplace, it's mostly for ambiance, although the wood burning stove in the kitchen at "La Casa de Camo" puts out some heat...
