CutSolar Home Cutaway Drawing 1979

This is a circa 1979 cutaway drawing of a solar-heated home in Falmouth, Massachusetts.  That part of Massachusetts has a 6,000 degree heating season, yet owner John Moody was able to get by spending only $9.63 in the 1978 winter.

The whole winter.

The house does not have solar panels that generate electricity.  Rather, the house collects solar heat, redistributes it, and saves it.  The pile of rocks (lower center section of cutaway) is one way of absorbing and storing heat.

The house is located at 5 Fire Tower Road, Falmouth, MA 02540.  Ironically, when I look on Google Street View to see if the house is still around, Fire Tower Road is lined with electric company utility trucks.
