I didn't see any mention in the wiki of integrated solar panels as a roofing
material. 

And for an even easier option there is now a peel and stick version. Nice
article in this months Mother Earth News. Peel and stick the solar panel to
the metal sheeting, tack it to the roof, cover the peak with a cap. The
panels interlock and the cap covers the electrical interconnects. Very
slick.

On the Geothermal Heating and Cooling page, there is no mention of earth
tubes. The Passive Solar Heating and Cooling page makes only passing
mention. Earth tubes are a really interesting idea in my opinion.

Ah... I see, "Trench Geothermal Cooling" 

I would also recommend a lot more interconnection between terms, but that
takes much work.

Overall, its great! I do wish more people would use the wiki abilities of
piclist.com, but...
