<p>Retired conservative engineer and solar expert. Married to the same woman since 1972. This home took 7 years to build. It has no wires from the outside world, is mostly heated by the sun and except for occasional generator use during winter, completely powered by the sun in frigid semi tropical Montana. I have a blog about solar that isn&apos;t hard to find. The 8 panels on the shop provide our electricity. The 6 on the house heat water. And yes, I really am a wild old Turkey. WWG1WGA</p>
